Abstract
Among the most widely used methods for understanding human-horse relationships in the archaeological record is the identification of human skeletal pathologies associated with mounted horseback riding. In particular, archaeologists encountering specific bony changes to the hip, femur, and lower back often assert a causal link between these features and prolonged periods of mounted horseback riding. The identification of these features have recently been used to assert the early practice of mounted horseback riding among the Yamnaya culture of western Eurasia during the third and fourth millennium BCE. Here, we summarize the methodological hurdles and analytical risks of using this approach in the absence of valid comparative datasets and outline best practices for using human osteological data in the study of ancient animal transport.

Hip adduction and abduction strength values in elite-level male and female youth soccer players: A comparison between sexes, and across age-groups. Phys Ther Sport 2024; 70:7-14. [PMID: 39178504 DOI: 10.1016/j.ptsp.2024.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Revised: 08/18/2024] [Accepted: 08/19/2024] [Indexed: 08/26/2024]
Abstract
OBJECTIVES To report isometric hip adduction squeeze and abduction press strength values of elite-level youth male and female soccer players and examine if differences exist between sexes, and age-groups. DESIGN Cross-sectional cohort study. SETTING Elite youth soccer academy. PARTICIPANTS 102 soccer players (n = 64; male, n = 38 female) competing in the national youth soccer leagues from under (U) 14-19 years of age level (U-14, U-15, U-17, U-19). MAIN OUTCOME MEASURES Isometric hip adduction and abduction strength values were measured with a ForceFrame in various testing positions. RESULTS Isometric hip adduction and abduction strength values are presented. Male U-17 and U-19 players demonstrated significantly greater (p < 0.05) absolute(N) and relative (N/kg) hip adduction and abduction strength than their female counterparts, with large (η2 = 0.068-0.227) and medium-to-large (η2 = 0.049-0.234) effect size, respectively. Significant differences in absolute strength, but not relative strength, were observed for hip adduction and abduction between male age-groups (U-14, U-15, U-17, U-19), with hip abduction strength differences only existing between U-14 and U-17 groups. No significant differences in hip strength were observed between U-17 and U-19 groups for female players. CONCLUSION Male youth soccer players have higher absolute and relative hip adduction and abduction strength than females at the U-17 and U-19 level.

Abstract
Isolated spontaneous tears in the non-insertional portion of the iliopsoas tendon without any underlying injury are uncommon, especially among elderly individuals. We describe the case of an 88-year-old man who experienced right groin pain caused by a spontaneous non-insertional tear in the iliopsoas tendon identified through ultrasound and confirmed via MRI. Ultrasound revealed hypoechogenicity in the non-insertional portion of the iliopsoas tendon, leading to quick identification and conservative treatment and resulting in positive functional outcomes. This case report emphasises the significance of considering spontaneous non-insertional iliopsoas tendon tears when evaluating cases of acute groin pain. This finding underscores the effectiveness of ultrasound as an initial diagnostic tool for the early cost-effective diagnosis of soft tissue injuries around the hip joint, especially in low-resource settings. Timely detection and management can help avoid unnecessary operative interventions and facilitate faster and better recovery.

Abstract
BACKGROUND While extensive research exists on muscle injuries among adult football players, a notable gap persists in studies concerning younger footballers. The aim of the current study is to provide epidemiological data on the characteristics of time-loss muscle injuries in young football players participating in the Italian Under-19 male elite Championship ("Primavera 1"). RESULTS Conducted as a multicentre, prospective, observational cohort study, this research gathered injury data from the 2022-23 season across 14 of the 18 Clubs in the first Italian Under-19 championship. The cohort comprised 391 players with a mean age (± standard deviation) of 18.0 ± 0.4 years. A total of 479 injuries were reported, resulting in 14,231 days of activity lost. Of these, muscle injuries were 209 (44%), accounting for 4,519 (32%) days lost. Overall muscle injuries incidence was 1.82/1000 hours, with a mean injury burden of 39.4 days lost/1000 hours. Almost all muscle injuries (206 out of 209: 98.5%) occurred in hamstrings, quadriceps, adductors, calf and iliopsoas. Hamstrings injuries were the most burdensome (18.8 days lost/1000 hours) accounting for nearly half of all days lost due to muscle injuries. Incidence and burden of adductors injuries (0.25 injuries and 4.1 days lost/1000 hours, respectively) were found to be comparable to calf injuries (0.24 injuries and 4.7 days lost/1000 hours, respectively). Iliopsoas injuries accounted for a noteworthy portion of the total, with an injury incidence of 0.16/1000 hours and a burden of 3.3 days lost/1000 hours. Injuries with myo-tendinous or myo-aponeurotic involvement demonstrated delayed return-to-football compared to those without such involvement (35.6 vs. 18.5 days, p < 0.0001). CONCLUSIONS The study highlighted a peculiar distribution of non-contact muscle injuries among elite young football players. While hamstring injuries were confirmed as the most burdensome, incidence and burden of adductors and calf injuries were found to be similar. A significant incidence and burden of iliopsoas injuries were observed. These findings suggest potential implementations for targeted injury prevention strategies in the Italian male elite Under-19 football Championship.

Goller M, Quittmann OJ, Alt T. How to activate the glutes best? Peak muscle activity of acceleration-specific pre-activation and traditional strength training exercises. Eur J Appl Physiol 2024; 124:1757-1769. [PMID: 38280014 PMCID: PMC11130056 DOI: 10.1007/s00421-023-05400-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 12/05/2023] [Indexed: 01/29/2024]
Abstract
PURPOSE Isometric training and pre-activation are proven to enhance acceleration performance. However, traditional strength training exercises do not mirror the acceleration-specific activation patterns of the gluteal muscles, characterized by ipsilateral hip extension during contralateral hip flexion. Therefore, the aim of the study was to determine gluteal muscle activity of acceleration-specific exercises compared to traditional strength training exercises. METHODS In a cross-sectional study design, the peak electromyographic activity of two acceleration-specific exercises was investigated and compared to two traditional strength training exercises each for the gluteus maximus and medius. Twenty-four participants from various athletic backgrounds (13 males, 11 females, 26 years, 178 cm, 77 kg) performed four gluteus maximus [half-kneeling glute squeeze (HKGS), resisted knee split (RKS), hip thrust (HT), split squat (SS)] and four gluteus medius [resisted prone hip abduction (RPHA), isometric clam (IC), side-plank with leg abduction (SP), resisted side-stepping (RSS)] exercises in a randomized order. RESULTS The RKS (p = 0.011, d = 0.96) and the HKGS (p = 0.064, d = 0.68) elicited higher peak gluteus maximus activity than the SS with large and moderate effects, respectively. No significant differences (p > 0.05) were found between the HT, RKS and HKGS. The RPHA elicited significantly higher gluteus medius activity with a large effect compared to RSS (p < 0.001, d = 1.41) and a moderate effect relative to the SP (p = 0.002, d = 0.78). CONCLUSION The acceleration-specific exercises effectively activate the gluteal muscles for pre-activation and strength training purposes and might help improve horizontal acceleration due to their direct coordinative transfer.

Abstract
BACKGROUND Female sex is a significant determinant of anterior cruciate ligament (ACL) injury. It is not understood if sex is a key determinant of other sports-related injuries. OBJECTIVE The aim of this systematic review was to identify where differences in injury profiles are most apparent between the sexes in all sports across the six-tiered participant classification framework. METHODS This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the 'implementing PRISMA in Exercise, Rehabilitation, Sport medicine and SporTs science'(PERSiST) guidance. The databases PubMed, CINAHL, Web of Science, SPORTDiscus, Medline, Scopus, Cochrane Library and EBSCO were searched from database inception to 24 April 2023. Longitudinal, prospective and retrospective cohort studies and cross-sectional and descriptive epidemiology studies that used standard injury data collection were included. Studies were excluded if injuries were not medically diagnosed and if injuries were not reported and/or analysed by sex. Two reviewers independently extracted data and assessed study quality using the Downs and Black checklist. RESULTS Overall, 180 studies were included (8 tier-5, 40 tier-4, 98 tier-3, 30 tier-2, 5 tier-1 studies; one study included data in two tiers). Of those, 174 studies were of moderate quality and six studies were of limited quality. In sex-comparable sports, there was moderate evidence that female athletes had greater risk of knee injury (relative risk (RR) 2.7; 95% CI 1.4-5.5), foot/ankle injuries (RR 1.25; 95% CI 1.17-1.34), bone stress injury (RR 3.4; 95% CI 2.1-5.4) and concussion (RR 8.46; 95% CI 1.04-68.77) than male athletes. Male athletes were at increased risk of hip/groin injuries (RR 2.26; 95% CI 1.31-3.88) and hamstring injuries (RR 2.4; 95% CI 1.8-3.2) compared with females, particularly in dynamic sports. Male athletes were 1.8 (1.37-2.7) to 2.8 (2.45-3.24) times more likely to sustain acute fractures than female athletes, with the highest risk in competition. DISCUSSION Most studies in all cohorts were of moderate quality (mean/range of scores tier-5: 17 ± 2.2 [14-20], tier-4: 16.9 ± 1.9 [11-21], tier-3: 16.9 ± 1.5 [11-20], tier-2: 16.3 ± 2.2 [11-20], tier-1 studies: 15.6 ± 1.3 [14-17] out of 28 on the Downs and Black checklist), with only six studies of limited quality. Female athletes' propensity for bone stress injuries highlights opportunities to reinforce development of optimal bone health during adolescence and to outline the effects of energy availability. Earlier strength development and exposure to neuromuscular training programmes and modification of skill development in female athletes may be effective strategies for reducing lower limb injury risk. Key components of neuromuscular training programmes could be beneficial for reducing hip/groin and hamstring injury risk in male athletes. There may be a need for sex-specific prevention and return-to-sport protocols for sports-related concussion in female athletes. CONCLUSIONS Female sex was a key determinant of sports-related injuries beyond ACL injury including foot/ankle injury, bone stress injury and sports-related concussion. Male sex was a key determinant of hip/groin, hamstring injury and upper limb injury. TRIAL REGISTRY PROSPERO registration number: CRD42017058806 (last updated on 7th June 2023).

Kelly M, Secomb J. Associations Between Hip Pathology, Hip and Groin Pain, and Injuries in Hockey Athletes: A Clinical Commentary. Int J Sports Phys Ther 2024; 19:625-641. [PMID: 38707850 PMCID: PMC11065768 DOI: 10.26603/001c.116580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/29/2024] [Indexed: 05/07/2024] Open
Abstract
Femoroacetabular impingement (FAI), particularly cam morphology, is highly prevalent among elite hockey athletes. Moreover, hip and groin pain has become a common issue in hockey, with approximately 50% of European professional athletes reported to experience a hip or groin problem during a season. While most athletes will not miss training or competition due to this, restricted competitive performance and increased risk of reduced physical and psychological well-being are likely. Recent research suggests that the development of cam morphology is related to the repetitive shear stresses experienced at the hip joint during adolescence from skating. This condition likely increases the potential for intra-articular and extra-articular injuries in these athletes later in their careers. Research also indicates that the hip joint mechanics during forward skating substantially increase the possibility of sustaining a labral tear compared to other sports. Such an injury can increase femoral head movement within the joint, potentially causing secondary damage to the iliofemoral ligament, ligamentum teres and joint capsule. These injuries and the high density of nociceptors in the affected structures may explain the high prevalence of hip and groin pain in hockey athletes. Compensatory adaptations, such as reduced hip strength, stability, and range-of-motion (ROM) likely increase the opportunity for core muscle injuries and hip flexor and adductor injuries. Specifically, the limited hip ROM associated with cam morphology appears to exacerbate the risk of these injuries as there will be an increase in pubic symphysis stress and transverse strain during rotational movements. It is hoped that this article will assist practitioners currently working with hockey athletes to develop evidence-informed monitoring strategies and training interventions, aimed at reducing the incidence and severity of hip and groin problems, ultimately enhancing athlete performance and well-being. Therefore, the purpose of this clinical commentary was to examine current evidence on common hip pathologies in hockey athletes, exploring potential associations between hip and groin pain and the biomechanics of hockey activities. Level of Evidence 5.

Abstract
OBJECTIVE To describe the prevalence, incidence, and burden of groin injuries in the Norwegian women's premier football league and to describe their clinical and imaging characteristics. METHODS During the 2020 and 2021 seasons, players in the Norwegian women's premier league reported groin injuries weekly, using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H2). We calculated weekly prevalence, incidence, and burden of groin injuries. The team physical therapists classified the player-reported injuries based on the Doha classification system. Injuries with more than 3 days' time loss or reported in 2 consecutive weeks were eligible for magnetic resonance imaging (MRI). RESULTS On average, 3.9% (95% CI: 3.4-4.4) of players reported a groin injury at any time; of which 78% caused time loss. The incidence rate was 1.6 injuries/1000 h (95% CI: 1.3-2.0) and their burden was 11 days lost/1000 h. The physical therapists examined 67 of 124 player-reported groin injuries (53%). Adductor-related injury was most common (55%) followed by iliopsoas (15%) and rectus femoris-related (12%). Pubic-related injuries caused most time loss (median: 24 days, IQR: 5-133). In this study, 42 injuries were investigated with MRI; 8 (19%) showed no changes, 6 (14%) an acute musculotendinous lesion, and 32 (76%) a nonacute finding (e.g., central symphyseal disc protrusion, tendinopathies). CONCLUSION The incidence rate and burden of groin injuries were high. Adductor-related injuries were most common, but pubic-related injuries caused most time loss. Most MRI examinations demonstrated nonacute findings.

Abstract
BACKGROUND In National Collegiate Athletic Association (NCAA) soccer athletes, men have higher rates of hip and groin strains, whereas women have higher rates of knee ligament injuries. Strength imbalances of the hip and thigh, specifically in agonist-antagonist muscles, are known risk factors for these injuries. OBJECTIVE To perform hip and thigh strength assessments in NCAA soccer players to evaluate for differences between genders and correlations with gender-specific injury patterns. DESIGN With a handheld dynamometer, weight-normalized isometric strength of six muscle groups (hip abductors, hip adductors, hip flexors, hip extensors, knee flexors, knee extensors) was calculated in NCAA soccer players. The strength ratio of each agonist-antagonist muscle was also calculated (hip abductors/adductors, hip flexors/extensors, knee extensors/flexors). PARTICIPANTS Thirty-six NCAA soccer players (18 men, 18 women) from a single NCAA Division III institution. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Weight-normalized strength of six muscle groups and their agonist-antagonist strength ratios were compared between genders using linear mixed-effects models. RESULTS Compared with male players, female players had decreased weight-normalized strength for hip abduction (0.170 vs. 0.204, p = .012) and hip extension (0.172 vs. 0.211, p = .021). Otherwise, weight-normalized strength was similar between genders. When comparing agonist-antagonist strength ratios, there was a significant difference between female and male players for hip flexion:extension (1.70 vs. 1.35, p = .008), whereas the hip abduction: adduction ratio did not reach statistical significance (1.45 vs. 1.62, p = .080). CONCLUSIONS NCAA male and female soccer players had different hip strength profiles that fit their injury patterns. Male NCAA soccer players have higher rates of hip and groin strains, and men in the cohort had strength ratios that were deficient in the hip flexors and adductors compared with women. Female NCAA soccer players have higher rates of knee sprains and anterior cruciate ligament tears, and women in the cohort had strength ratios that were deficient in the hip abductors and extensors, which function to stabilize the knee. These strength disparities could be the focus of future gender-specific soccer injury prevention programs.

Abstract
OBJECTIVES To describe and compare seasonal prevalence, anatomical location, severity, and onset of injuries between female and male elite ice hockey players. DESIGN Cross-sectional survey study. SETTING Elite ice hockey. PARTICIPANTS Swedish elite ice hockey players (170 females & 190 males). MAIN OUTCOME MEASURES Past season injuries reported on a modified version of the Oslo Sports Trauma Research Center overuse injury questionnaire. Proportions of players who experienced any and substantial problems, as well as respective injury severity scores were presented and compared between sexes. RESULTS Highest seasonal prevalence was reported for hip/groin [31.1% (n = 112)], lower back [24.2% (n = 87)], and shoulder injuries [23.6% (n = 85)]. Prevalence of injuries was approximately similar between sexes. Substantial injuries were most prevalent in the hip/groin (13.3% [n = 48]) and knee (18.6% [n = 67]) region. Females reported a higher proportion of substantial hip/groin injuries. Most reported injuries were acute except for hip/groin and lower back injuries (74.4% and 81.8% due to overuse). CONCLUSION Seasonal prevalence of injuries in elite ice hockey players were comparable between sexes. Acute injuries were most common but hip/groin as well as lower back injuries were predominantly due to overuse. The highest reported prevalence was found for hip and groin-, lower back-, and shoulder injuries.

Abstract
BACKGROUND Controversies remain regarding the diagnosis, imaging, and treatment of acute adductor injuries in athletes. PURPOSE To investigate the diagnostic imaging, treatment, and prevention of acute adductor injuries based on the most recent and relevant scientific evidence. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS The PubMed and Web of Science databases were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify articles studying acute adductor injury in athletes. Inclusion criteria were original publication on acute adductor injury in amateur or professional athletes, level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or the methodological index for non-randomized studies criteria. Articles were grouped as imaging, treatment, prevention focused, or mixed. RESULTS A total of 30 studies published between 2001 and 2021 were selected, involving 594 male patients with a mean age 26.2 years (range, 16-68 years). The most frequent sports were soccer (62%), basketball (14%), futsal (6%), American football (3%), and ice hockey and handball (2%). Risk factors for acute adductor injury were previous acute groin injury, adductor weakness compared with the uninjured side, any injury in the previous season, and reduced rotational hip range of motion. The frequency of complete adductor muscle tears on magnetic resonance imaging was 21% to 25%. For complete adductor tears, the average time to return to play was 8.9 weeks in patients treated nonoperatively and 14.2 weeks for patients treated surgically. Greater stump retraction was observed in individuals treated surgically. Partial acute adductor tears were treated nonoperatively with physical therapy in all studies in the present systematic review. The average time to return to play was 1 to 6.9 weeks depending on the injury grade. The efficacy of adductor strengthening on preventing acute adductor tears has controversial results in the literature. CONCLUSION Athletes with partial adductor injuries returned to play 1 to 7 weeks after injury with physical therapy treatment. Nonoperative or surgical treatment is an acceptable option for complete adductor longus tendon tear.

Abstract
ABSTRACT Hip pain is a common complaint in sports, and narrowing the differential diagnosis can be difficult. Many etiologies are secondary to overuse and respond well to nonsurgical treatment. The increased use of point-of-care ultrasound has helped provide timely and accurate diagnoses and some guided treatments. The hip is in close proximity to the abdomen and pelvis, and clinicians should be familiar with nonmusculoskeletal pain generators. This article is a comprehensive review of hip pain etiologies in athletes.

Abstract
Adductor-related groin pain is a common problem in sports. Evidence-based management of athletes with adductor strains, adductor ruptures, and long-standing adductor-related groin pain can be approached in a simple yet effective and individualized manner. In most cases, managing adductor-related pain in athletes should be based on specific exercises and loading strategies. In this article, I provide an overview of the different types of adductor injuries, from acute to overuse, including their underlying pathology, functional anatomy, diagnosis, prognosis, mechanisms, and risk factors. This information leads to optimal assessment and management of acute to long-standing adductor-related problems and includes primary, secondary, and tertiary prevention strategies that focus on exercise and load-based strategies. In addition, information on different options and contexts for exercise selection and execution for athletes, athletic trainers, and sports physical therapists in adductor injury rehabilitation is provided.

Abstract
Acute adductor injuries are a common occurrence in sport. The overall incidence of adductor strains across 25 college sports was 1.29 injuries per 1000 exposures, with men's soccer (3.15) and men's hockey (2.47) having the highest incidences. As with most muscle strains there is a high rate of recurrence for adductor strains; 18% in professional soccer and 24% in professional hockey. Effective treatment, with successful return to play, and avoidance of reinjury, can be achieved with a proper understanding of the anatomy, a thorough clinical exam yielding an accurate diagnosis, and an evidence-based treatment approach, including return to play progression.

Abstract
OBJECTIVES Hip and core injuries are common in National Football League (NFL) athletes; however, the impact following injury remains unclear. The goal of this manuscript was to determine the impact of nonoperative hip and core injuries on return to play and performance. METHODS NFL athletes who sustained a hip or core injury treated nonoperatively between 2010 and 2016 were identified. Offensive and defensive power ratings were calculated for each player's injury season and two seasons before and after to assess longitudinal impact. A matched control group without an identified hip and/or core injury was assembled for comparison. RESULTS A total of 41 offensive and 71 defensive players with nonoperative hip or core injury were analyzed. All athletes returned to play; offensive and defensive players missed 4.0 ± 5.2 and 3.1 ± 2.6 games after injury, respectively. Offensive players played fewer cumulative career games returning from core injury versus hip (23.5 ± 20.6 vs 41.0 ± 26.4). Defensive players played fewer games (58.1 ± 41.1 versus 37.4 ± 27.1, p < 0.05) with lower defensive power rating (133.9 ± 128.5 versus 219.8 ± 212.2, p < 0.05) cumulatively after hip or core injury. Additionally, 2 years following injury, defensive players played fewer games compared to controls (9.5 ± 7.0 versus 10.9 ± 6.8, p < 0.05). Following hip injury specifically, NFL defenders played fewer games (39.8 ± 27.9 vs 61.9 ± 38.8; p < 0.05) and had a lower defensive power rating (145.9 ± 131.7 vs 239.0 ± 205.9; p < 0.05) compared to before injury. CONCLUSION Overall, NFL players return to play following nonoperative hip and core injuries. Defensive players played in fewer games following hip or core injury compared to controls; offensive players were unaffected. Hip injuries have a greater impact on performance compared to core injuries in defensive athletes; offensive players played fewer games upon return from core injury.

Abstract
OBJECTIVES Baseball players are highly susceptible to shoulder injuries due to repetitive overhead throwing. The purpose of this study was to investigate men's collegiate baseball shoulder injury rates and associated risk factors. METHODS Using the NCAA Injury Surveillance Program (ISP) database, shoulder injury data for men's baseball players was analyzed from 2009-2010 through 2013-2014. Only the most common shoulder injuries were examined, including acromioclavicular (AC) sprain, anterior dislocation, biceps tear, biceps tendinitis, SLAP (superior labrum from anterior to posterior) tear, non-SLAP labral tear, rotator cuff tear, rotator cuff tendinitis, and shoulder impingement. Statistical analysis was performed using proportion ratios (PR). Statistical significance was initially defined as p < 0.05; a post-hoc Bonferroni adjustment was applied using a p < 0.005 threshold balancing the likelihood of false positive and false negative findings. RESULTS Overall, 138 shoulder injuries were identified of which 51.4% occurred during practice. Rotator cuff pathology represented 45.6% of all injuries, with rotator cuff tears significantly more likely to be season-ending injuries (PR 2.5, 95% CI 1.2-5.6, p = 0.019). Pitching or throwing was the mechanism of injury in 100% of players with rotator cuff tendonitis, 87.5% of SLAP tears, 70% of players with biceps tendinitis, and 67% of players with rotator cuff tears. Biceps tendinitis (PR 3.9, 95% CI 1.2-12.5, p = 0.024) and SLAP tears (PR 6.4, 95% CI 1.6-25.0, p = 0.008) were significantly more likely to be chronic. SLAP tears were significantly more likely to be recurrent (PR 5.5, 95% CI = 1.5-20.4, p = 0.010). Being a freshman or sophomore was significantly associated with a lower proportion of biceps tendinitis (PR = 0.2, 95% CI = 0.04-0.8, p = 0.028). All anterior shoulder dislocations occurred while running the bases or sliding, and AC sprains were significantly associated with contact (PR 20.6, 95% CI = 2.5-168.7, p = 0.0048). CONCLUSIONS Repetitive overhead throwing in college baseball is a common cause of overuse shoulder injuries. These athletes are especially susceptible to rotator cuff pathology, which is significantly more likely to cause season-ending injuries. While we have to interpret these results in light of both adjusted and unadjusted p-values, this information signifies the importance of shoulder injury prevention strategies by physicians and trainers taking care of collegiate baseball players.

Abstract
BACKGROUND Hurdling is a track event that is unique due to a combination of running and jumping over an apparatus. Since hurdling requires a special skillset with sprinting and jumping, athletes are at risk for various musculoskeletal injuries. However, there has been a paucity of studies describing the epidemiology of pediatric hurdle injuries. PURPOSE To examine hurdle-related injury types, injured body parts, injury mechanisms, and injury settings in children and adolescents. METHODS Descriptive epidemiology study. Data from the National Electronic Injury Surveillance System, which represents emergency room visits was retrospectively reviewed. Injury data involving hurdle injuries was searched during a 10-year period (2008-2017) with hurdlers 18 years of age and younger. Injuries were then classified based upon injury types, body parts, injury mechanisms, and injury settings. Descriptive statistics were used including mean ± standard deviation, frequency (N), and percentages (%). RESULTS A total of 749 hurdle-related injuries were found from 333 males (44.5%) and 416 females (55.5%). The top three injury types were traumatic fracture (N=218, 29.1%), joint sprain (N=191, 25.5%), and contusion/hematoma/bruise (N=78, 10.4%). The top three injured body parts were ankle (N=140, 18.7%), knee (N=120, 16.0%), and wrist (N=69, 9.2%). The most common injury mechanisms were apparatus-related trips, falls, and landings (N=594, 79.0%). Finally, injury settings consisted of track and field practices (N=469, 62.6%), track and field meets (N=96, 12.8%), and other settings including gym, physical education class, recess, school activities, and camps (N=49, 6.5%). CONCLUSION In pediatric hurdle athletes, the most prevalent injury type seen in the emergency room was fracture. Although most hurdle-related injuries occur in the lower extremity, injuries at the wrist were the 3rd most commonly injured body location. The most common injury mechanism was apparatus-related trip, fall, and landing, and injuries most commonly occurred during track practices. In pediatric hurdle athletes seen in the emergency room, majority of injuries consisted of traumatic fractures and joint sprains at ankle, knee, and wrist, which frequently occurred with apparatus-related trip, fall, and landing mechanisms during track and field practices.

Abstract
Background Bibliometric citation analyses have been widely used in medicine to help researchers gain foundational knowledge about a topic and identify subtopics of popular interest for further investigations. There is a lack of similar research in collegiate athletics. Purpose To identify the 100 most-cited research publications related to collegiate athletics. Study Design Cross-sectional study. Methods The Clarivate Analytics Web of Knowledge database was used to generate a list of articles relating to collegiate athletics on January 24, 2022. Articles were filtered by the total number of citations, and the 100 most-cited articles were selected. For each article, we identified and analyzed the following: author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, sex of study population, and level of evidence. Results Of the top 100 most-cited articles, 63 were related to medicine. In total, 96% of articles were published in the United States, and 80% were published in the year 2000 or later. Of the top 100 articles, 85 were observational; only 5 were experimental. The sport most represented was soccer, followed by football, baseball, and basketball. Of the top 100 articles, 21 were published in a single journal, the American Journal of Sports Medicine. Ten authors published ≥5 of the top 100 most-cited studies. Conclusion The majority of top 100 articles were published in the United States after 1999 and primarily focused on medicine-related topics. Soccer was studied by more articles than football, baseball, and basketball. An author's prestige may have influenced the likelihood of citation. The top 100 most-cited studies provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the literature on collegiate athletics.

Abstract
Background: Orthopaedic injuries are common in ice hockey at all levels and can result in physical and psychological adverse effects on these athletes. Purpose: Primarily, to summarize published data on orthopaedic hockey injuries at the junior through professional level. Secondarily, to characterize the literature based on anatomic site injured, return-to-play rates, cause/mechanism of injury, time lost, and treatments used. Study Design: Scoping review; Level of evidence, 4. Methods: PubMed, EMBASE, Cochrane library, and SCOPUS were searched using the terms “hockey” and “injuries” using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, and 4163 studies involving orthopaedic injuries were identified. Our inclusion criteria consisted of accessible full-text articles that evaluated orthopaedic injuries in men’s ice hockey athletes of all levels. We excluded case reports and articles evaluating women’s ice hockey injuries, as well as those evaluating nonorthopaedic injuries, such as concussions; traumatic brain injuries; and facial, dental, and vascular injuries, among others. Studies were divided based on level of play and anatomic site of injury. Level of evidence, year published, country of corresponding author, method of data collection, incidence of injury per athlete-exposure, and time lost were extracted from each article. Results: A total of 92 articles met the inclusion criteria and were performed between 1975 and 2020, with the majority published between 2015 and 2020. These were divided into 8 anatomic sites: nonanatomic-specific (37%), intra-articular hip (20.7%), shoulder (9.8%), knee (8.7%), trunk/pelvis (7.6%), spine (7.6%), foot/ankle (6.5%), and hand/wrist (2.2%). Of these studies, 71% were level 4 evidence. Data were obtained mostly via surveillance programs and searches of publicly available information (eg, injury reports, player profiles, and press releases). Conclusion: This scoping review provides men’s hockey players and physicians taking care of elite ice hockey athletes of all levels with a single source of the most current literature regarding orthopaedic injuries. Most research focused on nonanatomic-specific injuries, intra-articular hip injuries, knee injuries, and shoulder injuries, with the majority having level 4 evidence.

Abstract
Hockey is a fast-paced contact sport with a high incidence of injuries. Although injuries are more frequent among elite players, recreational hockey injuries are a common issue faced by primary care and emergency physicians. Lower extremity injuries in hockey are particularly important because they account for approximately a third of all injuries and > 60% of all overuse injuries. This pictorial review provides the general and specialty trained radiologist with a knowledge of the patterns of lower extremity injury that occur in ice hockey.

Abstract
CONTEXT The epidemiologic focus on time loss may underestimate the true magnitude of hip and groin problems in male ice hockey players. OBJECTIVE To describe the prevalence, incidence, and severity of hip and groin problems (time loss and non-time loss) in Swedish ice hockey players over the course of a season and explore potential preseason risk factors for these conditions. DESIGN Prospective 1-season cohort study. SETTING Professional and semiprofessional Swedish ice hockey players. PATIENTS OR OTHER PARTICIPANTS A total of 12 professional and semiprofessional male ice hockey teams were invited to participate. Of those, 9 teams agreed, and 163 players were included in the analyses. MAIN OUTCOME MEASURE(S) Hip and groin problems in the previous season (time loss, non-time loss), isometric adduction and abduction strength, and 5-second squeeze test results were recorded before the season and served as independent variables in the risk factor analysis. Main outcome measures were cumulative incidence of hip and groin problems, average prevalence, and odds ratios (ORs) for groin problems in season. RESULTS Cumulative incidence was 45.4% (95% CI = 37.6%, 53.4%) for all problems and 19% (95% CI = 13.3%, 25.9%) for substantial problems. Average prevalence was 14.1% (95% CI = 10.8%, 17.5%) for all and 5.7% (95% CI = 4.3%, 7.2%) for substantial problems. Among reported problems, 69.2% had a gradual onset, and only 17% led to time loss. Players with non-time-loss problems in the previous season had higher odds for new problems (all: OR = 3.3 [95% CI = 1.7, 6.3]; substantial: OR = 3.6 [95% CI = 1.8, 8.4]). Preseason strength was not significantly associated with the odds for subsequent problems. CONCLUSION Hip and groin problems are common in ice hockey players and may lead to substantial impairments in performance. Only 1 in 5 problems led to time loss, and 7 in 10 had a gradual onset. Non-time-loss problems in the previous season were a significant risk factor for new problems, whereas decreased preseason hip-adduction and -abduction strength was not.

Abstract
OBJECTIVE In this narrative review, we highlight sex-specific anatomic and biomechanical features of the hip region in female athletes, as well as the potential impact of these characteristics on observed disparities in both intra-articular and extra-articular injury patterns between female and male athletes. It is our goal to broaden the scope of knowledge related to hip pathology in active female athletes among sports medicine providers with the hope of better optimizing sport participation and performance in female athletes. DATA SOURCES A literature review was conducted using PubMed database and Google Scholar search engine. Search terms included sport, female, athlete, sex differences, injury, hip, and all diagnoses discussed in this review. Cross-reference of these articles identified additional resources. MAIN RESULTS Sex-specific differences in both static design and dynamic function contribute to disparities in hip injury patterns between female and male athletes. Intra-articular injuries, including labral and ligamentum teres pathology, as well as extra-articular injuries, including iliopsoas tendon dysfunction, gluteal and proximal hamstring tendinopathy, ischiofemoral impingement, bone stress injuries, and certain nerve entrapment syndromes, seem to affect female athletes more commonly than male counterparts. CONCLUSIONS Given unique anatomic and functional considerations, the growing population of female athletes worldwide warrants specialized care and consideration. Potential predisposition to specific hip injuries should be taken into consideration during diagnostic evaluation of hip pain in the female athlete.

Abstract
BACKGROUND Although lower back injuries (LBIs) are common among National Collegiate Athletic Association (NCAA) female volleyball athletes, their incidence and etiology has not been well-defined. PURPOSE To describe the epidemiology of LBIs in collegiate female volleyball athletes over a 5-year period from the academic years 2009 to 2010 and 2013 to 2014. STUDY DESIGN Descriptive epidemiology study. METHODS The incidence and characteristics of spine injuries were identified utilizing the NCAA Injury Surveillance Program database. Rates of injury were calculated as the number of injuries by the total number of athlete-exposures (AEs). AEs were defined as any student participation in any single NCAA-sanctioned practice or competition. The injury rate was computed as the number of injuries per the total number of AEs and reported as a ration of injuries per 10,000 exposures. The ratio was then reported as overall number as well as stratified for event, time of season, and athletic NCAA division. Incidence rate ratios were then calculated to compare rates between event type. Results with 95% CIs that did not include 1.0 were considered statistically significant. RESULTS An estimated 3384 LBIs occurred in NCAA female volleyball players during this 5-year time frame. These LBIs occurred at a rate of 4.89 injuries per 10,000 AEs. LBIs were 2.76 times more likely in preseason when compared with regular season. More injuries occurred in practice (85%) when compared with competition (15%). The outside hitter and middle blocker were the most commonly position to sustain an LBI. Almost 70% of injuries were new injuries, and another 29% were recurrent injuries. The most common mechanism of injury was equally split between contact (50.4%) and overuse (45.5%) injuries, whereas the remaining mechanisms of injury were secondary for unknown reasons (4.14%). Most players returned to play within 24 hours (72.3%) followed by 1 to 6 days (16.4%), and finally 7 to 12 days (11.3%). No patient required surgical intervention. CONCLUSION The rate of LBIs was high (4.89/10,000 AEs) and injuries commonly recurred (29.2%). Most injuries were new, with most athletes returning to play with 24 hours.

Abstract
BACKGROUND Groin strains are one of the most common time-loss injuries in athletes. The Copenhagen Adductor Exercise (CAE) eccentrically strengthens the adductors and may function to prevent adductor strains, similar to the eccentric mechanism in which the Nordic Hamstrings exercise acts to prevent hamstring strains. OBJECTIVE The purpose of this study was to systematically review the literature on the CAE and its effects on adductor muscle strength and muscle activity in athletes. STUDY DESIGN Systematic Review. METHODS A systematic search of the literature was performed in the following databases: Pubmed; Medline (EBSCO); Sportdiscus; Scopus; Web of Science; CINAHL; Proquest; Cochrane Library; Physiotherapy Evidence Database (PEDro). Inclusion criteria consisted of 1) implements CAE, 2) includes athletes of any age participating in at least one sport, 3) study type is a cohort study or randomized control trial. Studies were excluded if they were not written in English or did not measure strength as an outcome. Data were extracted on eccentric hip adductor strength (EHAD), eccentric hip abductor strength (EHAB), EHAD:EHAB ratio, and electromyography (EMG) activity of the adductor muscles. Quality assessment was performed on all included studies using Quality Assessment Tool for Quantitative Studies. RESULTS Five articles were identified for inclusion, four of which received a strong rating, and one a moderate rating on the Quality Assessment Tool for Quantitative Studies. The CAE significantly increased EHAD in four of the four studies that examined it; significantly increased EHAB and EHAD:EHAB in three of the three studies that examined them, and increased the EMG activity of the adductors in the dominant leg 108%. CONCLUSION Overall, the CAE increases EHAD, EHAB, EHAD:EHAB, and EMG activity in the hip adductors in male soccer players. The increase in strength may reduce adductor muscle injuries, although more research needs to be done in this area to identify a clear relationship between the CAE and groin injury prevention.

Abstract
Background: Spine injuries are common in collegiate wrestlers and can lead to reinjury, persistent pain, and time lost from participation. Purpose: To describe the epidemiology of spine injuries in National Collegiate Athletic Association (NCAA) wrestlers between academic years 2009 to 2010 and 2013 to 2014. Study Design: Descriptive epidemiology study. Methods: The incidence and characteristics of spine injuries were identified utilizing the NCAA–Injury Surveillance Program database. Spine injuries were assessed for injury type, injury mechanism, time of season, event type, recurrence, participation restriction, and time lost from participation. Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). Injury rate ratios (IRRs) were calculated for event type and time of season, and results with 95% confidence intervals that did not include 1.0 were considered statistically significant. Results: There were an estimated 2040 spine injuries reported in the database over the 4-year period, resulting in an injury rate of 0.71 per 1000 AEs. Spine injuries were over twice as likely to occur in competitions as in practices (IRR, 2.02; 95% confidence interval, 1.10-3.69). More injuries occurred in both the preseason (0.94 per 1000 AEs) and the postseason (1.12 per 1000 AEs) compared with the regular season (0.55 per 1000 AEs). Contact injuries (42%) were the most common mechanism of injury, and brachial plexus injury (20%) was the most common diagnosis. Only 1.3% of injuries required surgery, and athletes most commonly returned to sport within 24 hours (33%) or within 6 days (25%). Conclusion: This investigation found an overall injury rate of 0.71 per 1000 AEs in wrestling athletes between academic years 2009 to 2010 and 2013 to 2014. The majority of these injuries were new, and athletes most commonly returned to sport within 24 hours. The injury rate was highest in competition, and both the preseason and the postseason showed a higher injury rate than that in season. Efforts to improve injury prevention and management should be informed by these findings.

Abstract
Hip pain is a common complaint in athletes and can result in a significant amount of time lost from sport. Diagnosis of the source of hip pain can be a clinical challenge because of the deep location of the hip and the extensive surrounding soft tissue envelope. Establishing whether the source of hip pain is intra-articular or extra-articular is the first step in the process. A thorough history and a consistent and comprehensive physical examination are the foundation for the proper management of athletes with hip pain.

Abstract
Background The effects of foot injuries on collegiate athletes in the United States are of interest because of the short 5-year eligibility period in the National Collegiate Athletic Association (NCAA). Purpose To discuss the epidemiology of severe NCAA foot injuries sustained over 10 years in 25 sports. Study Design Descriptive epidemiology study. Methods We utilized the NCAA Injury Surveillance System, which prospectively collects deidentified injury data for collegiate athletes. Severe injuries were classified as season- or career-ending injuries, injuries with >30-day time loss, or injuries requiring operative treatment. Injury rates (IRs) were analyzed per 100,000 athlete-exposures. Results Of 3607 total foot injuries, 18.71% (n = 675) were classified as severe, with an IR of 5.73 per 100,000 athletic-exposures. For all severe injuries, the operative rate was 24.3%, the season-ending rate 37.0%, and the career-ending rate 4.4%. The proportion of recurrent injuries was 13.9%. Men's sports with the highest severe foot IRs were basketball (IR = 10.71), indoor track (IR = 7.16), and football (IR = 7.08). Women's sports with the highest severe foot IRs were cross-country (IR = 17.15), gymnastics (IR = 14.76), and outdoor track (IR = 14.65). Among all severe foot injuries, the most common was a fifth metatarsal fracture. The highest contact/noncontact injury ratios were phalangeal fracture, turf toe, and Lisfranc injury. The severe injuries with the highest operative rates were Lisfranc injuries, fifth metatarsal fractures, and midfoot fractures. The severe injuries associated with the highest season-ending IRs were Lisfranc injury, midfoot fracture, and general metatarsal fractures. Severe flexor/extensor injuries had the highest career-ending IRs, followed by turf toe. Severe injuries with the highest median time loss were sesamoidal fractures, calcaneal fractures, and plantar fascial injuries. Conclusion Of all collegiate foot injuries sustained over a 10-year period, 18.7% were characterized as severe, and 24.3% of severe injuries required surgery. Basketball was the men's sport with the highest severe IR, and cross-country was the women's sport with the highest severe IR. Overall, female athletes experienced slightly higher severe foot IRs as compared with male athletes.

Abstract
The incidence of strain injuries continues to be high in many popular sports, especially hamstring strain injuries in football, despite a documented important effect of eccentric exercise to prevent strains. Studies investigating the anatomical properties of these injuries in humans are sparse. The majority of strains are seen at the interface between muscle fibers and tendon: the myotendinous junction (MTJ). It has a unique morphology with a highly folded muscle membrane filled with invaginations of collagen fibrils from the tendon, establishing an increased area of force transmission between muscle and tendon. There is a very high rate of remodeling of the muscle cells approaching the MTJ, but little is known about how the tissue adapts to exercise and which structural changes heavy eccentric exercise may introduce. This review summarizes the current knowledge about the anatomy, composition and adaptability of the MTJ, and discusses reasons why strain injuries can be prevented by eccentric exercise.

Abstract
The athlete's hip is complex when it comes to the surrounding musculature-approximately 21 different muscles can cross the hip and pelvis region, all synchronously working to maintain pelvic stability and functional hip activities. Commonly injured muscle groups for high-level athletes include flexors, adductors, abductors, and/or proximal hamstring musculotendinous complex. These muscle groups work in harmony; however, each has an independent function and propensity for injury. Rehabilitation phases for each injury group can be broken down into 3 phases: acute management, strengthening, and return-to-sport or return-to-competition phase. Specific rehabilitation principles and modalities are described for each injury group.

Abstract
Hip injuries are common in the athletic population, typically occurring in sports as a result of contact or overuse. Previous literature describes differences in injury rates between male and female athletes, clinical presentation, treatment, and outcomes. In addition, anatomic differences in acetabular and femoral version, hip alpha angles, lateral center-edge angles, pelvic tilt, and knee biomechanics have been demonstrated. These differences may alter injury patterns between male and female athletes and contribute to differences in hip pathology. Therefore, individualized treatment and rehabilitation strategies should be taken into consideration in order to expedite an athlete's return to play.

Abstract
Athletic injuries to the hip flexors and iliopsoas have been described in populations across all levels of competitive sports. Overall estimates of hip flexor pathology have ranged from 5% to 28% of injuries among high-risk sport specific groups. Although most of these injuries are successfully treated with conservative management, and high rates of return to play are observed, significant rehabilitation time can be involved. As the understanding of hip pathology with imaging modalities such as MRI has advanced, greater importance has been placed on accurately diagnosing hip flexor injuries and initiating rehabilitation protocols early to minimize time loss from sport.

Abstract
Background The present study investigated the impact of competitive soccer on the short-term changes in isometric strength of the adductor muscle group during the competitive season. Methods In this cohort study we evaluated the association between a serum marker of muscle damage [creatine phosphokinase (CPK)] and isometric strength of the adductor muscles of the hip in 30 professional football players (age: 26.7±2.9 years) during two seasons of the national top-level championship. Serum CPK level was determined the day before the match, 12–20, 36–48, 60–72 h after the match. The maximum voluntary isometric contraction force of the adductor muscles complex was determined immediately after having taken blood samples. Results There was evidence of a statistically significant positive association between age, body mass index (BMI), percentage of body fat, and muscle strength, and between weight and muscle strength. There was evidence of a statistically significant negative association between the level of CPK and the maximum isometric strength of the adductors of soccer players. Changes in CPK levels were associated with the muscle strength recovery trend (P<0.001). The strength/CPK ratio at different time points had a U-shaped curve. Conclusions Exercise induced muscle damage significantly affects the strength of the adductor muscle group of professional soccer players during the competitive period. The lower the CPK level, the greater the athletes' strength at a given time point. Also, the greater the decrease in CPK level, the greater the rate of strength restoration.

Abstract
Objectives: 1) To evaluate return to play (RTP) timing in National Basketball Association (NBA) athletes following adductor injuries, and 2) to evaluate the effect of adductor injuries on player performance, game availability, and career longevity following RTP. Methods: Adductor injuries in NBA athletes from the 2009-2010 to 2018-2019 seasons were identified utilizing publicly available records via previously validated methodology. RTP time was calculated, and player performance and game availability were compared pre- vs. post-injury. Additionally, an injury-free control group matched for age, BMI, position, and experience was assembled to allow for comparisons in performance, availability, and career length. Results: In total, 79 adductor injuries across 65 NBA athletes were identified. The average injured player was 28.3 ± 4.0 years of age, and had 6.5 ± 4.2 seasons of NBA experience. Guards were injured more frequently than forwards or centers (49% vs 25% vs 25%, respectively). All players were able to RTP following first-time adductor injury after missing an average of 7.7 ± 9.8 games (median [IQR]: 4 [1-9]) and 16.9 ± 20.4 days (median [IQR]: 9 [3.5-20]). Twelve players (18.5%) suffered an adductor re-injury at a mean latency of 509.5 ± 503.9 days. Adductor injuries did not result in significant changes in any major statistical category (points, assists, rebounds, steals, blocks, turnovers, field goal percentage), player efficiency rating (PER), minutes/game, games/season, or a number of all-star selections (all P > 0.05) following RTP. Additionally, when compared to matched controls, no difference was found in pre- to post-injury change of PER, games/season, or minutes/game (all P > 0.05). Career longevity was not significantly different between groups (P = 0.44). Conclusion: Following adductor injury, NBA players returned to gameplay after missing an average of 16 to 17 days, or 7 to 8 games. Adductor injury did not affect player performance, nor game availability or career longevity.

HIP AND GROIN PROBLEMS IN THE PREVIOUS SEASON ARE ASSOCIATED WITH IMPAIRED FUNCTION IN THE BEGINNING OF THE NEW SEASON AMONG PROFESSIONAL FEMALE ICE HOCKEY PLAYERS - A CROSS SECTIONAL STUDY. Int J Sports Phys Ther 2020; 15:763-769. [PMID: 33110695 DOI: 10.26603/ijspt20200763] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022] Open
Abstract
Background Hip and groin problems are common in ice hockey but studies on professional female players are sparse. The available literature describes hip and groin problems by reporting incidence of time-loss injuries and may thereby underestimate the scope of these problems, which are often due to overuse and may not lead to absence from ice hockey participation. Purpose The purpose of this study was to describe the seasonal prevalence and severity of hip and groin problems in professional female ice hockey players. A further aim was to examine the relation between previous problems and self-reported function in the beginning of the new season. Study design Cross-sectional study. Methods Female ice hockey players from the highest league in Sweden [n=69 (19 goalkeepers, 18 defenders, 30 forwards)], responded to an online survey, retrospectively assessing the prevalence of hip and groin problems (time loss and non-time loss) and their duration during the previous season. Furthermore, players reported current self-reported function on the Copenhagen Hip and Groin Outcome Score (HAGOS). Results Two thirds of the players experienced hip and groin problems during the previous season [62.3% (N=43)]. A quarter of the players experienced a hip and groin problem leading to time loss [26.1% (N=18)]. The majority of problems were of short (1-2 weeks) or medium (3-5 weeks) duration [29% (N=20) of players, respectively], while longstanding problems ( ≥ 6 weeks) were rare [4,4% (N=3)]. Players that retrospectively reported hip and groin problems during the previous season reported statistically significant impairments on all HAGOS subscales in the beginning of the new season (p ≤ 0.011). Conclusion Hip and groin problems are prevalent in professional female ice hockey players, experienced by 62% during the previous season with resulting time-loss in 26.1%. Reported problems were rarely of longstanding nature, but players who reported problems in the previous season had significantly impaired hip and groin function in the beginning of the new season. Even though results of this study are based on retrospective player reports this may be a first step toward a greater understanding of the true burden of hip and groin players in professional female ice hockey players.

Abstract
Psychological pressure during sports competition disturbs the ideal physical movement and causes injury. Baseball batting frequently causes trunk injuries. This study aimed to examine the influence of psychological pressure on the lumbar kinematics and trunk muscle activity during the baseball batting. Fourteen collegiate baseball players participated in this study. The participants performed bat swings under three different psychological conditions (non-pressure, pressure, and emphasized pressure). The lumbar kinematics and trunk muscle activity were measured during each bat swing. One- and two-way analyses of variance were performed to compare the lumbar kinematics and trunk muscle activity among different psychological pressure conditions. The lumbar flexion angle throughout the bat swing in the swing phase, from the moment of ground contact of the lead foot to the moment of ball contact, was significantly larger under the pressure and emphasized pressure conditions than under the non-pressure condition (P<0.05). The bilateral lumbar erector spinae (LES) activities in the swing and follow-through phases were significantly higher under the emphasized pressure condition than under the non-pressure condition (P<0.05). These results indicate that the baseball batting under psychological pressure influenced the lumbar kinematics and bilateral LES activities and may be related to the development of low back pain.

Abstract
Background: Hip and groin injuries are common in competitive soccer players and have been shown to be significant sources of time loss. There are few studies describing the epidemiology of hip and groin injuries in female National Collegiate Athletic Association (NCAA) soccer players. Purpose: To describe the epidemiology of hip and groin injuries in women’s collegiate soccer players. Study Design: Descriptive epidemiology study. Methods: The NCAA Injury Surveillance System/Program (ISS/ISP) was analyzed from 2004 through 2014 for data related to hip and groin injuries in female collegiate soccer players. Injuries and athlete-exposures (AEs) were reported by athletic trainers. Data were stratified by time of season, event type, injury type, treatment outcome, time loss, and player field position. Results: Between 2004 and 2014, there were 439 recorded hip or groin injuries in female soccer players and an overall rate of injury of 0.57 per 1000 AEs. Injuries were 12.0 times more likely to occur during the preseason (4.41/1000 AEs) as opposed to during the regular season (0.37/1000 AEs) (injury rate ratio [IRR], 12.01; 95% confidence interval [CI], 9.92-14.55) or postseason (0.38/1000 AEs) (IRR, 11.55; 95% CI, 7.06-18.91). Rates of injury were similar during the regular season and postseason (IRR, 0.96; 95% CI, 0.59-1.58). Rates of injury were higher during competition (0.69/1000 AEs) than during practice (0.52/1000 AEs) (IRR, 1.33; 95% CI, 1.08-1.63). Most injuries were new (87.5%; n = 384) and unlikely to recur (12.5%; n = 55). Conclusion: Hip and groin injuries in female NCAA soccer players are uncommon, and fortunately, most players return to play quickly without recurrence. Future prospective studies should evaluate the effectiveness of strength and conditioning programs in preventing these injuries.

Abstract
STUDY DESIGN Descriptive epidemiology study. OBJECTIVE The purpose of this study was to describe the epidemiology of neck and cervical spine injuries in collegiate athletes over a 5-year period. SUMMARY OF BACKGROUND DATA The incidence and etiology of neck and cervical spine injuries in National Collegiate Athletic Association (NCAA) athletes has not been well defined in recent years. METHODS The incidence and characteristics of neck and cervical spine injuries were identified utilizing the NCAA Injury Surveillance Program database. Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). AEs were defined as any student participation in one NCAA-sanctioned practice or competition. RESULTS Nationally, there were an estimated 11,510 neck and cervical spine injuries over the 5-year period. These occurred at a rate of 7.05 per 100,000 athlete-exposures (AEs). The rate of neck and cervical spine injuries in men was 2.66 per 100,000 AEs, while women suffered injuries at a rate of 1.95 per 100,000 AEs. In sex-comparable sports, men were 1.36 times more likely to suffer a neck or cervical spine injury compared with women. Men's football (29.09 per 100,000 AEs) and women's field hockey (11.51 per 100,000 AEs) were the sports with the highest rates of injuries. These injuries were 3.94 times more likely to occur during competition compared with practice. In-season injury rates were the highest, at 8.18 per 100,000 AEs. CONCLUSION The vast majority of neck and cervical spine injuries in NCAA athletes are minor and uncommon. Across all sports in both sexes, the majority of injuries were new, and occurred during in-season competitions. Most athletes returned to play within 24 hours of injury. These data can inform players, parents, coaches, athletic trainers, and physicians regarding the prevalence and rates of these injuries and potentially inform decision-making regarding injury prevention, treatment, and rehabilitation.

Abstract
PURPOSE The prevalence of hip and groin problems in professional male ice hockey is unknown and suspected to differ between playing positions. The purpose of this study was to explore potential differences in the seasonal prevalence of hip and groin problems between playing positions in male elite ice hockey players and to explore the relationship between symptom duration and hip and groin function at the beginning of the new season. METHODS Male ice hockey players [n = 329 (92 goalkeepers, 93 defensemen, 144 forwards), Mean age (SD): 24 (5)] from the professional leagues in Sweden responded to an online survey. The survey assessed presence of hip and groin problems (time loss and non-time loss) and symptom duration (categorized into 0, 1-6, or > 6 weeks) in the previous season, and current self-reported hip and groin function (Copenhagen Hip and Groin Outcome Score). RESULTS During the previous season, 175 players (53.2%) had experienced hip and groin problems. Non time loss problems were experienced by 158 (48%) and time loss problems were experienced by 97 (29.5%) players. No significant differences between playing positions were found. Self-reported function differed significantly between players with different symptom duration and more disability was reported among players with longer symptom duration (p ≤ 0.002). CONCLUSION Regardless of playing position, hip and groin problems were prevalent in male ice hockey players. Players with hip and groin problems during the previous season had significantly worse hip and groin function in the beginning of the new season, and longer symptom duration was associated with more disability.

Abstract
BACKGROUND The modern style of goalkeeping in ice hockey is thought to predispose athletes to hip and groin problems. However, little is known about the magnitude of these problems in elite goalkeepers. PURPOSE To describe the incidence, prevalence, and severity of hip and groin problems in elite ice hockey goalkeepers over the course of a single season. STUDY DESIGN Descriptive epidemiology study. METHODS We invited all elite Swedish ice hockey goalkeepers (n = 128) to participate in this prospective cohort study. Every second week, players reported hip and groin problems experienced within the past 14 days on the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O), classifying problems into "all" and "substantial" hip and groin problems. Three times during the season (pre-, mid-, and end-season), players reported hip and groin function on the Hip and Groin Outcome Score (HAGOS) as well as on the OSTRC-O. RESULTS A total of 101 goalkeepers participated in the study (83.3% male [seniors, 44.1%; juniors, 39.2%], 16.7% female). The cumulative incidences of all hip and groin problems and substantial hip and groin problems were 69% (95% CI, 59%-79%) and 36% (95% CI, 26%-46%), respectively. The average biweekly prevalence for all hip and groin problems and substantial hip and groin problems was 28.1% (95% CI, 25.0%-31.3%) and 10% (95% CI, 8.7%-11.4%), respectively. Among all the reported hip and groin problems, 16.9% (n = 70) were acute, 83.1% (n = 343) were because of overuse, and 15.5% (n = 64) led to time loss. HAGOS did not differ in the pre-, mid-, or end-season. Players reporting hip and groin problems on the OSTRC-O had significantly worse HAGOS scores than players without problems (P < .01). CONCLUSION Hip and groin problems are highly prevalent in elite ice hockey goalkeepers. During a competitive season, 69% of players experienced hip and groin problems and 36% of players suffered from substantial problems. The vast majority of problems were because of overuse, not leading to time loss but related to reduced self-reported hip and groin function.

Abstract
Background: Lumbar spine injuries (LSIs) are common in both men’s and women’s National Collegiate Athletic Association (NCAA) basketball players and can frequently lead to reinjuries and persistent pain. Purpose: To describe the epidemiology of an LSI in collegiate men’s and women’s basketball during the 2009-2010 through 2013-2014 academic years. Study Design: Descriptive epidemiology study. Methods: The incidence and characteristics of LSIs were identified utilizing the NCAA Injury Surveillance Program (ISP). Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). AEs were defined as any student participation in 1 NCAA-sanctioned practice or competition. Incidence rate ratios (IRRs) were then calculated to compare the rates of injury between season, event type, mechanism, injury recurrence, and time lost from sport. Results: The NCAA ISP reported 124 LSIs from an average of 28 and 29 men’s and women’s teams, respectively. These were used via validated weighting methodology to estimate a total of 5197 LSIs nationally. The rate of LSIs in women was 2.16 per 10,000 AEs, while men suffered LSIs at a rate of 3.47 per 10,000 AEs. Men were 1.61 times more likely to suffer an LSI compared with women. In men, an LSI was 3.48 times more likely to occur in competition when compared with practice, while in women, an LSI was 1.36 times more likely to occur in competition than in practice. Women suffered the highest LSI rate during the postseason, while the highest rate in men was during the regular season. The majority of both female (58.9%; n = 1004) and male (73.1%; n = 2353) athletes returned to play within 24 hours of injury. Conclusion: To date, this is the largest study to characterize LSIs in NCAA basketball and provides needed information on the prevalence and timing of these injuries. The majority of injuries in both sexes were new, and most athletes returned to play in less than 24 hours. Injury rates were highest during competition in both sexes.

Abstract
Background: Although football is one of the most popular collegiate sports, the epidemiology of and risk factors for shoulder and elbow injuries in this population not been recently described. We aimed to characterize this incidence in National Collegiate Athletic Association (NCAA) football players, determine risk factors, and establish outcomes after injury. Methods: All shoulder and elbow injuries in men's football occurring during the 2009-2010 through 2013-2014 academic years were retrospectively identified in the NCAA Injury Surveillance Program database. The injury incidence per 10,000 athletic exposures (AEs) was calculated overall, and by different risk factors. In addition to descriptive statistics, risk factors were compared using injury risk-ratios, and outcomes were compared using injury proportion ratios. Results: NCAA football players sustained 1,187 shoulder and elbow injuries in 899,225 AEs (incidence: 13.20/10,000 AE), most commonly acromioclavicular separation (29.9%), anterior shoulder subluxation (9.0%), shoulder contusion (9.0%), and rotator cuff tear/sprain (8.0%). Together, shoulder instability comprised 28.1% of injuries. Injuries were split evenly between offense (43.5%) and defense (45.9%), and a tackling mechanism caused 37.7%, with 30.3% coming from blocking. The incidence was eight times higher in competition than practice (62.9/10,000 vs 7.9/10,000AE, p < 0.001). Surgery was performed for 9.9% of injuries, and most commonly for all types of shoulder instability (56.8% of surgeries). Injuries were season-ending in 5.2% of players. The likelihood of an injury being season-ending was 2.9 times greater for recurrent injuries than a new injury (p < 0.001); 86.1% of all injuries were new. Conclusions: Shoulder and elbow injuries to NCAA football players can be severe. Competition had an eight times higher incidence than did practice. Tackling and blocking were the most common mechanisms, while AC separation and shoulder instability were the most common injuries. This epidemiology may help players, coaches, trainers, and governing bodies target injury-prevention programs and assess improvement over time.

Abstract
Background: Little research has focused on the rates and patterns of elbow injuries in
National Collegiate Athletic Association (NCAA) student-athletes. Purpose: To describe the epidemiological patterns of elbow injuries in NCAA athletes
during 5 seasons over the academic years 2009 through 2014 using the NCAA
Injury Surveillance Program (NCAA-ISP) database. Study Design: Descriptive epidemiology study. Methods: A voluntary convenience sample of NCAA varsity teams from 11 sports was
examined to determine the rates and patterns of elbow injuries. Rates and
distributions of elbow injuries were identified within the context of sport,
event type, time in season, mechanism, time lost from sport, surgical
treatment, and injury type. Rates of injury were calculated as the number of
injuries divided by the total number of athlete-exposures (AEs). An AE was
defined as any student participation in 1 NCAA-sanctioned practice or
competition with an inherent risk of exposure to potential injury. Injury
rate ratios (IRRs) and injury proportion ratios (IPRs) were then calculated
to compare the rates within and between sports by event type, season, sex,
mechanism, surgical treatment, and time lost from sport. Comparisons between
sexes were made using only sports data that had both male and female
samples. Results: Overall, 373 elbow injuries were reported in the NCAA-ISP data set during the
2009-2010 through 2013-2014 academic years among 11 varsity sports. The
overall rate of injury was 1.76 per 10,000 AEs. The rate of elbow injuries
in men was 0.74 per 10,000 AEs, while women experienced injuries at a rate
of 0.63 per 10,000 AEs. In sex-comparable sports, men were 1.17 times more
likely to experience an elbow injury compared with women. Men’s wrestling
(6.00/10,000 AEs) and women’s tennis (1.86/10,000 AEs) were the sports with
the highest rates of elbow injuries by sex, respectively. The top 3 highest
injury rates overall occurred in men’s wrestling, baseball, and tennis.
Elbow injuries were 3.5 times more likely to occur during competition
compared with practice. Athletes were 0.76 times less likely to sustain an
elbow injury during the preseason compared with in-season. Contact events
were the most common mechanism of injury (67%). For sex-comparable sports,
men were 2.41 times more likely than women to have contact as their injury
mechanism (95% CI, 0.78-7.38). The majority of athletes missed less than 24
hours of participation time (67%), and only a minority (3%) of patients with
elbow injuries went on to have surgical intervention. Elbow ulnar collateral
ligament injuries were most common (26% of total injuries). Conclusion: Analysis of the study data demonstrated a significant rate of elbow injuries,
1.76 injuries per 10,000 AEs in NCAA collegiate athletes. Higher injury
rates can be expected in males within sex-comparable sports. Elbow injuries
are most common in the setting of competitions and most commonly occur
secondary to contact-type mechanisms. Injuries were more likely to occur
during in-season play. The majority of injuries required less than 24 hours
of time away from sport and did not require surgical intervention.

Abstract
Background: Low back injuries are common in collegiate football players and can frequently lead to persistent pain, reinjuries, and time lost from participation. Purpose: To describe the epidemiology of back injuries in National Collegiate Athletic Association (NCAA) football players during the 2009/2010 through 2013/2014 academic years utilizing the NCAA Injury Surveillance Program (ISP) database. Study Design: Descriptive epidemiology study. Methods: A convenience sample of NCAA varsity football teams was utilized to determine the rates and patterns of back injuries as well as to generate national injury estimates. The rates and distribution of back injuries were identified within the context of mechanism of injury, injury chronicity, and time lost from sport. Injury rates were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). Incidence rate ratios were calculated to compare the rates of injury between season, event type, mechanism of injury, injury chronicity, and time lost from sport. Results: Nationally, there were 267 low back injuries reported in the database. These were used to estimate 7076 back injuries over the 5-year period, approximately 82% of which were new injuries. The injuries occurred at a rate of 2.70 per 10,000 AEs. Overall, injuries were 3.12 times more likely to occur in competitions than in practices. Athletes were 4.67 times more likely to sustain a back injury during the preseason compared with the postseason but were 1.41 times more likely to sustain a low back injury during the preseason compared with the regular season. Both contact and noncontact were reported equally as the mechanism of injury (37.8% and 38.3%, respectively), and unspecified low back pain was the most common injury (64.2%). Only 1.6% of patients required surgery for their injury, and the majority of athletes (59.6%) returned to play within 24 hours. Conclusion: There was a relatively high rate of lumbar back injuries at the collegiate level (2.70/10,000 AEs), the majority of which were new injuries. About 18% of reported injuries were reinjuries. Although very few required surgery, a careful examination and work-up should be conducted to evaluate each injury. Regimented physical therapy and reconditioning programs are recommended to avert reinjuries.

Abstract
STUDY DESIGN Descriptive epidemiology study. OBJECTIVE The purpose of this study was to describe the epidemiology of cervical spine injuries in collegiate football players. SUMMARY OF BACKGROUND DATA The incidence and etiology of cervical spine injuries in National Collegiate Athletic Association (NCAA) football players has not been well defined in recent years. METHODS The incidence and characteristics of cervical spine injuries were identified utilizing the NCAA-ISP database. Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). AEs were defined as any student participation in one NCAA-sanctioned practice or competition. RESULTS An estimated 7496 cervical spine injuries were identified. Of these, 85.6% were categorized as new injuries. These occurred at a rate of 2.91 per 10000 AEs. Stingers were most common (1.87 per 10000 AEs) followed by cervical strains (0.80 per 10000 AEs). Injuries were nine times more likely to occur during competition when compared with practice settings. When compared with the regular season, the relative risks of sustaining a cervical spine injury during the preseason and postseason were 0.69 (95% CI 0.52-0.90) and 0.39 (95% CI 0.16-0.94), respectively. The rate of cervical spine injuries was highest in Division I athletes. Direct contact-related injuries were most common, representing 90.8% of all injuries sustained. Injuries were most common in linebackers (20.3%) followed secondarily by defensive linemen (18.2%). Most players returned to play within 24 hours of the initial injury (64.4%), while only 2.8% remained out of play for > 21 days. CONCLUSION Fortunately, the rate of significant and disabling cervical spine injuries appears to be low in the NCAA football athlete. The promotion of safer tackling techniques, appropriate modification of protective gear, and preventive rehabilitation in these aforementioned settings is of continued value. LEVEL OF EVIDENCE 4.

Abstract
CONTEXT The complex, high-energy nature of football puts players at risk for hip injuries. OBJECTIVE To analyze National Collegiate Athletic Association (NCAA) Injury Surveillance Program data for men's football hip injuries from 2004-2005 through 2013-2014. DESIGN Descriptive epidemiologic study. SETTING National Collegiate Athletic Association football teams. PATIENTS OR OTHER PARTICIPANTS Data on collegiate football players was provided by the NCAA Injury Surveillance System from 2004-2005 through 2013-2014. MAIN OUTCOME MEASURE(S) The incidence, risk factors, rates, and distribution of hip injuries over the 10-year period from 2004-2005 through 2013-2014 were determined. Rates and distribution of injuries were analyzed by injury type, time loss, event type, time of season, recurrence, mechanism of injury, player position, and if surgery was required. Injury rate ratios were calculated to compare rates between event types and by time of season. RESULTS A total of 1618 hip injuries occurred during 3 121 380 athlete-exposures (AEs), resulting in an overall hip injury rate of 5.18 per 10 000 AEs. Adductor strains (38.63%) were the most common type, followed by hip-flexor strains (28.55%) and hip contusions (18.23%). Players were 3.56 (95% confidence interval [CI] = 3.19, 3.98) times more likely to sustain a hip injury during competitions compared with practices. They were 2.37 (95% CI = 2.15, 2.62) and 3.56 (95% CI = 2.49, 5.08) times more likely to sustain a hip injury during the preseason than in-season or the postseason, respectively. CONCLUSIONS During the 10-year period, NCAA football players sustained higher rates of hip injuries during competitions and the preseason. The majority were noncontact injuries, resulted in time loss of less than 6 days, and did not require surgery. The injuries varied with player position and occurred most often to defensive backs. Muscle strains were the most frequent group of hip injuries, while adductor strains, hip-flexor strains, and hip contusions were the most common injury types.

Abstract
Background: Lumbar spine injuries in National Collegiate Athletic Association (NCAA) athletes have not been well studied. Purpose: To describe the epidemiology of lumbar spine injuries in NCAA athletes during the 2009/2010 through 2014/2015 academic years utilizing the NCAA Injury Surveillance Program (ISP). Study Design: Descriptive epidemiology study. Methods: A voluntary convenience sample of NCAA varsity teams from 25 sports was examined. Mechanism of injury, injury recurrence, and time lost from sport were recorded. Injury rates were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). AEs were defined as any student participation in 1 NCAA-sanctioned practice or competition. Injury rate ratios and injury proportion ratios were calculated to compare the rates within and between sports by event type, season, patient sex, mechanism, injury recurrence, and time lost from sport. Comparisons between sexes were made utilizing data that had both male and female samples. Results: An estimated 37,435 lumbar spine injuries were identified. The overall rate of injuries was 6.01 per 1000 AEs. The rate of injuries was 4.94 per 1000 AEs in men compared with 3.94 per 1000 AEs in women for sex-comparable sports. Men were 1.25 times more likely than women to suffer a lumbar spine injury. Men’s football (24.62 injuries/1000 AEs) and women’s gymnastics (11.46 injuries/1000 AEs) had the highest rates of lumbar spine injuries. Athletes were 1.83 and 3.71 times more likely to sustain a lumbar spine injury during the preseason than the regular season or postseason, respectively. Noncontact was the most common mechanism of injury (38%). Injury recurrence was most common in men’s outdoor track (58%). Most injuries resulted in less than 24 hours of time loss from event participation (61%). Conclusion: The rate of lumbar spine injuries was high in NCAA athletes, and injuries commonly recurred (20%). In general, men were more likely to sustain a lumbar spine injury compared with women. Higher injury rates occurred during competition and via a noncontact mechanism of injury. In addition to prevention programs, reconditioning programs should be considered to prevent these injuries.

Abstract
The physical and demanding style of play in soccer places these athletes at an elevated risk for hip and groin injuries. Several studies have examined hip and groin injuries in professional and youth soccer in European countries, but few have involved American counterparts. Hip injury data were analyzed retrospectively from the National Collegiate Athletic Association Injury Surveillance Program for the 2004 to 2014 academic years for collegiate men's soccer. This study found that hip and groin injuries among collegiate male soccer players were most often new injuries (87.8%; n=527) that were noncontact in nature (77.3%; n=464) and resulted in time loss of less than 7 days (67.5%; n=405). Hip injuries were significantly more likely during the pre-season (5.72 per 1000 athlete exposures) relative to in-season (injury proportion ratio, 1.64; 95% confidence interval, 1.39-1.94) and post-season (injury proportion ratio, 1.69; 95% confidence interval, 1.18-2.41). Further, they were more likely in competition relative to practice (injury proportion ratio, 2.33; 95% confidence interval, 1.98-2.74). The most common injuries were adductor strains (46.5%; n=279) followed by hip flexor strains (27.3%; n=164) and hip contusions (10.8%; n=65). Among these injuries, adductor (73.1%; n=204) and hip flexor (59.8%; n=98) strains were more commonly noncontact related and occurred in practice, whereas hip contusions were due to contact and during competition. The study of the complex and lingering nature of hip and groin injuries in soccer players is critical because these injuries not only are prevalent but also have multifactorial risks associated with coexisting pathologies that make them difficult to prevent and treat effectively.
