Kim HG, Jung JH, Bae SU. Effects of the Three-Direction Movement Control Focus Complex Pain Program and Neurodynamic Focus Complex Pain Program on Pain, Mechanosensitivity, and Body Function in Taekwondo Athletes with Non-Specific Low Back Pain: A Preliminary Study. Healthcare (Basel) 2024; 12:422. [PMID: 38391798 PMCID: PMC10887569 DOI: 10.3390/healthcare12040422] [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: 12/13/2023] [Revised: 01/28/2024] [Accepted: 02/01/2024] [Indexed: 02/24/2024] Open
Abstract
We aimed to determine the effects of three-direction movement control focus complex pain program (3D-MCE) and neurodynamic focus complex pain program (NDT) on pain, mechanosensitivity, and body function in Taekwondo athletes with non-specific low back pain. This study used a two-group pretest-posttest design and was conducted at a university physiotherapy lab and training center. It included 21 Taekwondo athletes with non-specific low back pain from a Taekwondo studio and a University in Busan. Participants were divided into a 3D-MCE group (n = 10) and an NDT group (n = 10). The numerical rating pain scale (NRPS), pain pressure threshold (PPT), movement analysis, and Oswestry Disability Index (ODI) were measured before and after the intervention. The intervention was performed for 45 min twice a week for 4 weeks. Each group performed movement control exercises and neurodynamic techniques. The NRPS, motion analysis, and ODI were significantly changed after the intervention in the 3-DMCE group. The NRPS, PPT, and ODI changed significantly after the intervention in the NDT group. Moreover, the PPT and motion analysis showed significant differences between the two groups. For Taekwondo athletes with non-specific low back pain, 3D-MCE improved the stability control ability of the lumbar spine. It was confirmed that neurodynamic techniques reduce muscle and nerve mechanosensitivity.

Abstract
Combat sports require participants to engage in potentially dangerous forms of contact-based competition. Pressure to succeed, coupled with the risk of severe injury can induce significant levels of anxiety, which if uncontrolled, can negatively impact performance and possibly promote unsporting conduct. The present study examined competitive anxiety levels of combat sports athletes and determined whether self-reported scores were associated with mental toughness and Sportspersonship attitudes. A cross-sectional survey design was used whereby participants (N = 194) completed a battery of questionnaires measuring competitive combat sport experiences, demographic details, Sportspersonship traits (compliance towards rules, respect for opponents, and game perspective), and competition anxiety (somatic, cognitive, and self-confidence; reported retrospectively). Results suggest that mentally tough athletes experience lower levels of cognitive and somatic anxiety, and higher self-confidence, prior to competitions. Findings also found that athletes endorsing more altruistic and respectful attitudes in sport (Sportspersonship) reported higher levels of competition anxiety. The findings demonstrate that mental toughness is allied to positive attributes and could potentially be operationalized to improve both the retention and performance of combat sports athletes. Thus, the authors advocate the use of mental toughness coaching interventions within combat sports.

Abstract
Background and Objectives: Neck and shoulder injuries are common in Brazilian ju-jitsu (BJJ) athletes, and scapular dyskinesis (SD) is associated with these injuries. This study aimed to investigate the prevalence of SD in BJJ athletes, their neck and shoulder function and strength, and the BJJ training period. Materials and Methods: Forty-eight BJJ athletes participated in the study. Years of experience with BJJ, belt, shoulder internal and external rotation strength, neck strength, neck disability index (NDI), and SD were measured. Results: Approximately 31 BJJ athletes (64.6%) showed SD, and the nondominant arm showed a more obvious SD (n = 22, 45.8%) than the dominant arm (n = 18, 37.5%). Those with over five years of BJJ training experience showed a significantly higher rate of SD (p = 0.006) than those with less than five years of experience. Shoulder isometric internal rotation strength was significantly weaker in the obvious SD group than in the normal SD group (p = 0.014). Neck isometric strength and NDI did not differ significantly between individuals with or without SD. Conclusions: SD was common among BJJ athletes, and more experienced BJJ athletes exhibited higher rates of SD. Shoulder rotational strength was weaker with SD. Further studies are necessary on the neck and shoulders of BJJ athletes with SD.

Abstract
Objective To determine the injury incidence proportion, distribution of injuries by anatomical location; injury type; injury severity, time loss; mechanism and situations of injuries; and the relative risk of injuries by gender, age, and weight categories during judo tournaments. Study Design. It is a systematic review. Data Sources. A systematic review of the literature was conducted via searches in PubMed, EMBASE, Web of Science, CINAHL, SPORTDiscus, Google Scholar, and PEDro. Eligibility Criteria. All original studies on the incidence of injuries during judo tournaments were included. Results Twenty-five studies were included out of the 1979 studies. Using the modified AXIS tool score for quality assessment, seven were rated as having good quality, nine were rated as having fair quality, and four were rated as having poor quality. The injury incidence proportion during tournaments ranged from 2.5% to 72.5% for injuries requiring medical evaluation and 1.1% to 4.1% for injuries causing time loss (i.e., inability to continue game participation). The most commonly reported injury location was the head, followed by the hand, knee, elbow, and shoulder. The most frequent types of injury were sprains, followed by contusions, skin lacerations, strains, and fractures. In judo tournaments, injuries were more often sustained during standing fights (tachi-waza) than in ground fights (ne-waza). Conclusion The tournament injury incidence proportion ranged from 2.5% to 72.5% for injuries requiring medical attention and 1.1% to 4.1% for injuries causing time loss. The head was the most frequently injured body part, and sprain was the most frequent injury type. However, current reports on injuries during judo tournaments are heterogeneous and inconsistent, limiting our understanding of in-match injury risks. Future studies should utilize the guidelines of the International Olympic Committee consensus meeting statement on the methodological approach to injury reporting. We recommend a judo-specific extension of this statement to fit the unique features of judo sports practice.

Abstract
ABSTRACT Combat sports are very common in sport mega-events. Taekwondo is a combat sport that prioritizes direct contact between participants, specially by kicks and punches, and provides ambiguity in the health-sport relationship, as its practice could be harmful. This study aimed to quantify the prevalence of injuries in amateur Taekwondo athletes, from training or competitions, and assess their association with intrinsic and extrinsic factors. This is a descriptive, observational, and retrospective study that assessed injuries by a reported morbidity inquiry. Information on sports injuries considered the last six months of 2018. Participants were athletes aged from 12 to 25 years old, of both sexes, practicing Taekwondo in the city of Pelotas, Rio Grande do Sul, Brazil. The prevalence of sports injuries in amateur Taekwondo athletes in Pelotas was 26.2% (n=1), without significant differences between sexes. The main reason for the practice was physical conditioning (35.7%). The main mechanism of injury was kick when attacking (45.4%), followed by impact when defending (27.3%). The most frequent type of injury was sprain (27.3%). followed by contusion (18.2%), and the most injured body parts were knees (36.4%) and ankles (36.4%). The prevalence of sports injuries in amateur Taekwondo athletes in Pelotas was lower than the one found in the literature, and it may be due to the nature of the practice, as they are recreational amateur athletes aiming to improve physical conditioning.

Abstract
RESUMO As modalidades esportivas de combate (MEC) são muito frequentes em megaeventos esportivos e, dentre elas, destaca-se o taekwondo, que prioriza o contato direto entre os participantes principalmente a partir de chutes e socos, e proporciona ambiguidade na relação saúde-desporto, pois sua prática pode ser lesiva. O objetivo do estudo foi quantificar a prevalência de lesões em atletas recreacionais de taekwondo, oriundas de treinos ou competições, e testar sua associação a fatores intrínsecos e extrínsecos. Trata-se de estudo observacional descritivo, de natureza retrospectiva, que empregou inquérito de morbidade referida para registro dos agravos. As informações quanto à lesão desportiva foram registradas considerando os últimos seis meses de 2018. Participaram atletas com idade entre 12 e 25 anos, de ambos os sexos, praticantes de taekwondo na cidade de Pelotas, no Rio Grande do Sul. A prevalência de lesões desportivas em praticantes recreacionais de taekwondo na cidade de Pelotas é 26,2% (n=11), sem diferenças significantes entre sexos. O principal motivo de prática é o condicionamento para saúde (35,7%); o principal mecanismo de lesão foi chute atacando (45,4%), seguido de impacto ao realizar defesa (27,3%); o tipo de lesão mais frequente foi entorse (27,3%), seguido de contusão (18,2%); e os segmentos corporais mais lesionados foram joelho (36,4%) e tornozelo (36,4%). A prevalência de lesões desportivas em praticantes recreacionais de taekwondo da cidade de Pelotas é inferior à encontrada na literatura, e isto pode decorrer da natureza da prática, dado que eles são atletas recreacionais amadores, com a prática direcionada ao condicionamento para a saúde.

Abstract
Sports participation is not without risk, and most athletes incur at least one injury throughout their careers. Combat sports are popular all around the world, and about one-third of their injuries result in more than 7 days of absence from competition or training. The most frequently injured body regions are the head and neck, followed by the upper and lower limbs, while the most common tissue types injured are superficial tissues and skin, followed by ligaments and joint capsules. Nutrition has significant implications for injury prevention and enhancement of the recovery process due to its effect on the overall physical and psychological well-being of the athlete and improving tissue healing. In particular, amino acid and protein intake, antioxidants, creatine, and omega-3 are given special attention due to their therapeutic roles in preventing muscle loss and anabolic resistance as well as promoting injury healing. The purpose of this review is to present the roles of various nutritional strategies in reducing the risk of injury and improving the treatment and rehabilitation process in combat sports. In this respect, nutritional considerations for muscle, joint, and bone injuries as well as sports-related concussions are presented. The injury risk associated with rapid weight loss is also discussed. Finally, preoperative nutrition and nutritional considerations for returning to a sport after rehabilitation are addressed.

Abstract
OBJECTIVE The purpose of this study was to describe the concussion-related symptoms reported among combat sport athletes with and without a history of concussion, and a history of neck injury. DESIGN Cross-sectional survey. SETTING Data were collected using an online survey instrument. PARTICIPANTS Three hundred and nine adult combat sport athletes. MAIN OUTCOME MEASURES Self-reported 12-month concussion history and neck injury history and a 22-item symptom checklist. RESULTS A history of concussion was reported by 19.1% of athletes, a history of neck injury was reported by 23.0%, and 13.6% reported both injuries. Neck pain was the most frequently reported symptom. Athletes with a history of injury had significantly greater proportions of 'high' total symptoms and symptom severity scores compared with athletes with no history of injury. Athletes with a history of concussion had 2.35 times higher odds of reporting 'high' total symptoms and symptoms severity scores. CONCLUSION Athletes with a history of concussion or neck injury have greater odds of presenting with higher symptom scores. The presence of high total symptom scores and high symptom severity scores may indicate a need for further investigation into domains commonly associated with concussion.

Abstract
Background Musculoskeletal injuries (MSK-I) are a serious problem in sports medicine. Modifiable and non-modifiable factors are associated with susceptibility to these injuries. Thus, the aim of this study was to describe the prevalence of and identify the factors associated with MSK-I, including tendinopathy and joint and muscle injuries, in athletes. Methods In this cross-sectional observational study, 627 athletes from rugby (n = 225), soccer (n = 172), combat sports (n = 86), handball (n = 82) and water polo (n = 62) were recruited at different sports training centres and competitions. Athlete profiles and the prevalence of MSK-I were assessed using a self-reported questionnaire. Only previous MSK-I with imaging confirmation and/or a positive physical exam by a specialized orthopaedist were considered. The association of the epidemiological, clinical and sports profiles of athletes with MSK-I was evaluated by a logistic regression model. Results The mean age was 25 ± 6 years, and 60% of the athletes were male. The epidemiological, clinical and sports profiles of the athletes were different for the five sport groups. The MSK-I prevalence among all athletes was 76%, with 55% of MSK-I occurring in a joint, 48% occurring in a muscle and 30% being tendinopathy, and 19% of athletes had three investigated injuries. The MSK-I prevalence and injury locations were significantly different among sport groups. There was a predominance of joint injury in combat sports athletes (77%), muscle injury in handball athletes (67%) and tendinopathy in water polo athletes (52%). Age (≥30 years) was positively associated with joint (OR = 5.2 and 95% CI = 2.6–10.7) and muscle (OR = 4.9 and 95% CI = 2.4–10.1) injuries and tendinopathy (OR = 4.1 and 95% CI = 1.9–9.3). Conclusion There is a high prevalence of tendinopathy and joint and muscle injuries among rugby, soccer, combat sports, handball and water polo athletes. The analysis of associated factors (epidemiological, clinical and sports profiles) and the presence of MSK-I in athletes suggests an approximately 4–5-fold increased risk for athletes ≥30 years of age. The identification of modifiable and non-modifiable factors can contribute to implementing surveillance programmes for MSK-I prevention.

Abstract
Limited research has systematically examined injuries resulting from Brazilian Jiu Jitsu (BJJ), Judo, and mixed martial arts (MMA), especially when compared to more well-known or -established martial arts. These three combative sports differ substantially regarding their rules and techniques. BJJ emphasizes ground positioning and submission, Judo rewards throwing an opponent on their back with submission ending the match, and MMA emphasizes knocking out or forcing the submission of one's opponent. We examined injuries, among people of any age, experienced from participation in BJJ, Judo, and MMA. We analyzed data from the United States (U.S.) Consumer Product Safety Commission National Electronic Injury Surveillance System to create estimates of injuries presenting to U.S. emergency departments (EDs). We compared injury profiles between sports, including estimated numbers of injuries, their site, type, and mechanism. Participation in BJJ, Judo, and MMA resulted in an estimated 39,181 injuries presenting to U.S. EDs from 2008 through 2015. Strains and sprains were the most common diagnoses for BJJ and Judo participants, whereas abrasions/contusions were the most commonly diagnosed MMA injury. Being struck resulted in the majority of injuries for all three sports. The head was the most injured body region for BJJ and MMA, whereas the leg was the most injured body region for Judo. Finally, the majority of BJJ and Judo injuries occurred during noncompetitive grappling, whereas most MMA injuries occurred during competition. Our study adds to the limited literature examining injuries from BJJ, Judo, and MMA using data from a probability sample and is an initial step towards understanding the national burden of injury from participation in these sports. Given the quantity and severity of injuries sustained by participants, additional research is needed to assess the riskiness of participation and the effectiveness of interventions, such as improved personal protective gear and mats, as a means to prevent commonly occurring injuries.

Abstract
BACKGROUND Physical activeness is one of the main elements of lifestyle in terms of preventing civilization diseases. The main purpose of this study was to assess the selected health behaviors of men practicing combat sports and martial arts and to find out what features or variables may have an influence one's lifestyle. METHODS Overall, 561 men aged 17-35 yr were enrolled and divided into three groups. Studies were conducted from March 2011 to June 2015 in Warsaw, Poland. The main research tool was Juczyński's Health Behaviour Inventory. The questionnaire includes 24 statements - descriptions of various health-related attitudes and behaviours - divided into four categories: proper eating habits, preventive behaviours, positive psychical attitude, and health practices. RESULTS The persons practicing combat sports and martial arts presented the highest level of health behaviours. The result of Group 1 was significantly higher than the result of Group 2 (P=0.05) and Group 3 (P<0.001). The sportsmen from Group 1 obtained the highest result in the category of psychical attitude (3.5), which was similar to the result of the non-active group (3.29). The men belonging to Group 2 rated highest their eating habits (3.37). All groups obtained the lowest results in the category of preventive behaviours. CONCLUSION The men practicing combat sports and martial arts showed high general level of health behaviours. It may give evidence to the intellectualization of sport and health training process, as well as to the fact of adopting the desired behaviours in everyday life.

Collection of such data permits the analysis of injury and illness trends, improves early detection of injuries and illnesses, collectively referred to as health problems, and provides evidence to inform prevention strategies. The Athlete Management System (AMS) has been employed across a range of sports to monitor health. Australian combat athletes train across the country without dedicated national medical or sports science teams to monitor and advocate for their health. Employing a Web-based system, such as the AMS, may provide an avenue to increase the visibility of health problems experienced by combat athletes and deliver key information to stakeholders detailing where prevention programs may be targeted. OBJECTIVE The objectives of this paper are to (1) report on the feasibility of utilizing the AMS to collect longitudinal injury and illness data of combat sports athletes and (2) describe the type, location, severity, and recurrence of injuries and illnesses that the cohort of athletes experience across a 12-week period. METHODS We invited 26 elite and developing athletes from 4 Olympic combat sports (boxing, judo, taekwondo, and wrestling) to participate in this study. Engagement with the AMS was measured, and collected health problems (injuries or illnesses) were coded using the Orchard Sports Injury Classification System (version 10.1) and International Classification of Primary Care (version 2). RESULTS Despite >160 contacts, athlete engagement with online tools was poor, with only 13% compliance across the 12-week period. No taekwondo or wrestling athletes were compliant. Despite low overall engagement, a large number of injuries or illness were recorded across 11 athletes who entered data-22 unique injuries, 8 unique illnesses, 30 recurrent injuries, and 2 recurrent illnesses. The most frequent injuries were to the knee in boxing (n=41) and thigh in judo (n=9). In this cohort, judo players experienced more severe, but less frequent, injuries than boxers, yet judo players sustained more illnesses than boxers. In 97.0% (126/130) of cases, athletes in this cohort continued to train irrespective of their health problems. CONCLUSIONS Among athletes who reported injuries, many reported multiple conditions, indicating a need for health monitoring in Australian combat sports. A number of factors may have influenced engagement with the AMS, including access to the internet, the design of the system, coach views on the system, previous experiences with the system, and the existing culture within Australian combat sports. To increase engagement, there may be a requirement for sports staff to provide relevant feedback on data entered into the system. Until the barriers are addressed, it is not feasible to implement the system in its current form across a larger cohort of combat athletes.

The use of nonparametric effect sizes in single study musculoskeletal physiotherapy research: A practical primer. Phys Ther Sport 2018; 33:117-124. [PMID: 30077090 DOI: 10.1016/j.ptsp.2018.07.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2017] [Revised: 07/16/2018] [Accepted: 07/16/2018] [Indexed: 01/23/2023]
Abstract
There is a strong push for the inclusion of effect size indexes alongside the reporting of statistical analysis in academic journals. Nonparametric methods of analysis have generally been developed less than their parametric counterparts have, and are also generally less well known. Too often researchers use parametric statistics where nonparametric measures would be more appropriate. This holds true for nonparametric measures of effect size, where even when researchers use nonparametric statistics, some use parametric effect size measures to interpret the result. This paper attempts to provide a practical overview and illustration of the correct usage and interpretation of effect size measures for nonparametric statistics for single study designs using real-world physiotherapy data in the worked examples. This primer covers a range of different formulae based on categorical measures of effect size, as well as between- and within-group designs using ranked data. While this primer does use examples focusing on physiotherapy research, the applications of the information can be used in any field of research.

A cross-sectional study. BMC Sports Sci Med Rehabil 2017; 9:16. [PMID: 29075501 PMCID: PMC5651575 DOI: 10.1186/s13102-017-0080-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2016] [Accepted: 10/15/2017] [Indexed: 11/10/2022]
Abstract
BACKGROUND Brazilian jiu-jitsu is characterized by musculoskeletal disorders and high occurrence of sports injuries. The present study was aimed to analyze some internal factors, as well as to describe occurrence and characteristics of retrospective musculoskeletal injuries in different age groups of Brazilian jiu-jitsu practitioners. METHODS One hundred ninety-three Brazilian jiu-jitsu practitioners, which were divided into three age groups: Adolescent, Adult, and Master. Besides anthropometric characterization, standard clinical tests were conducted to analyze the global and segmental joint flexibility, lumbar spine range of motion, and handgrip strength. Sports injury occurrence and total physical activity were obtained from an adapted morbidity survey and International Physical Activity Questionnaire - Short Form (IPAQ-SF), respectively. RESULTS A total of 247 cases of retrospective injuries was registered (1.27 injury/ participant). Occurrence of rectus femoral muscle retraction in the right leg was increased within Master. Adult and Master have exhibited higher occurrence of sports injuries than Adolescent group (p < 0.05). Joint injuries were the most common sports-related injuries by all Brazilian jiu-jitsu practitioners. While female gender and exposure time constituted the most predictive variables for sports injury occurrence in Adolescent, graduation level was more associated with sports injuries occurrence in Adult. CONCLUSIONS Joint injuries derived from combat demands were the main sports injury in all age categories of Brazilian jiu-jitsu. Master subjects presented a higher occurrence of clinical changes and retrospective musculoskeletal injuries in relation to other age groups. Female gender and exposure time constituted the main predictive factors in adolescent subjects, while graduation category was more directly associated with retrospective injury onset in the Adult group.

Abstract
BACKGROUND Combat sports involve body contact through striking, kicking and/or throwing. They are anecdotally referred to as 'dangerous', yet long-term investigation into specific injury rates is yet to be explored. OBJECTIVE To describe incidence and prevalence of injury and illness within Olympic combat sports and to investigate risk of bias of prospective injury and illness research within these sports. METHODS We systematically searched literature published up until May 2016. We included prospective studies of injury/illness in elite combat athletes lasting more than 12 weeks. Risk of bias was assessed using a modified version of the Downs and Black checklist for methodological quality. Included studies were mapped to the Oxford Centre for Evidence-Based Medicine levels of evidence. RESULTS Nine studies were included, and most (n=6) had moderate risk of bias. Studies provided level 1/2b evidence that the most frequently injured areas were the head/face (45.8%), wrist (12.0%) and lower back (7.8%) in boxing; the lower back (10.9%), shoulder (10.2%) and knee (9.7%) in judo; the fingers (22.8%) and thigh (9.1%) in taekwondo; and the knee (24.8%), shoulder (17.8%) and head/face (16.6%) in wrestling. Heterogeneity of injury severity classifications and inconsistencies inexposure measures prevented any direct comparisons of injury severity/incidence across combat sports. CONCLUSIONS There is currently a lack of consensus in the collection of injury/illness data, limiting the development of prevention programmes for combat sport as a whole. However, sport-specific data that identify body areas with high injury frequency can provide direction to clinicians, enabling them to focus their attention on developing pathologies in these areas. In doing so, clinicians can enhance the practical elements of their role within the integrated combat sport performance team and assist in the regular update of surveillance records.

Abstract
[Purpose] Respiratory physiotherapy is an effective approach to improving lung function
in patient, including athletes with respiratory dysfunction caused by sports injury. The
purpose of this study was to analyze the differences in the respirograms between taekwondo
poomsae athletes and nonathletes according to the respirogram phase. [Subjects and
Methods] Respiratory measurements for 13 elite taekwondo poomsae athletes were obtained.
Respiratory function was measured using spirometry while the participant was seated.
[Results] In respirogram phasic analysis, the inspiratory area of forced vital capacity
were significantly increased in the athletes than in the nonathletes. The slopes of the
forced vital capacity for athletes at slopes 1, 2, and 3 of the A area were significantly
higher than those for the nonathletes. In correlation analysis, chest circumference was
significantly correlated with slope 1 of the A area of the forced vital capacity.
[Conclusion] Results indicate that differences in respirogram phasic changes between
athletes and nonathletes may contribute to better understanding of respiratory function,
which is important to sports physiotherapy research.

Abstract
[Purpose] Bicycle saddle height is a critical factor for cycling performance and injury
prevention. The present study compared the variance in cadence frequency after exercise
fatigue between saddle heights with 25° and 35° knee flexion. [Methods] Two saddle
heights, which were determined by setting the pedal at the bottom dead point with 35° and
25° knee flexion, were used for testing. The relative variances of the cadence frequency
were calculated at the end of a 5-minute warm-up period and 5 minutes after inducing
exercise fatigue. Comparison of the absolute values of the cadence frequency under the two
saddle heights revealed a difference in pedaling efficiency. [Results] Five minutes after
inducing exercise fatigue, the relative variances of the cadence frequency for the saddle
height with 35° knee flexion was higher than that for the saddle height with 25° knee
flexion. [Conclusion] The current finding demonstrated that a saddle height with 25° knee
flexion is more appropriate for cyclists than a saddle height with 35° knee flexion.

Abstract
[Purpose] The purpose of the present study was to elucidate the muscle conditions such as the isokinetic muscle of Korean ssireum athletes. [Subjects and Methods] This study enrolled 25 elite ssireum athletes. We measured body composition and peak torque at an angular speed at 60°/s using an isokinetic muscle strength dynamometer. [Results] The lean body mass of the left upper limb was significantly higher than that of the right upper limb. However, the lean body mass of the left lower limb was significantly lower than that of the right lower limb. The peak torque for left elbow flexion was significantly higher than that for right elbow flexion. Conversely, the peak torque for left elbow extension was significantly lower than that for right elbow extension. Furthermore, the peak torque for the left knee was significantly lower than that for the right knee for both flexion and extension. [Conclusion] The data from this study elucidate in part the muscle conditions of Korean ssireum athletes, which can be used to establish a reference for the scientific study of sports physiotherapy.
