Abstract
Advancements in technology have recently allowed us to collect and analyse large-scale fine-grained data about human performance, drastically changing the way we approach sports. Here, we provide the first comprehensive analysis of individual and team performance in One-Day International cricket, one of the most popular sports in the world. We investigate temporal patterns of individual success by quantifying the location of the best performance of a player and find that they can happen at any time in their career, surrounded by a burst of comparable top performances. Our analysis shows that long-term performance can be predicted from early observations and that temporary exclusions of players from teams are often due to declining performances but are also associated with strong comebacks. By computing the duration of streaks of winning performances compared to random expectations, we demonstrate that teams win and lose matches consecutively. We define the contributions of specialists such as openers, all-rounders and wicket-keepers and show that a balanced performance from multiple individuals is required to ensure team success. Finally, we measure how transitioning to captaincy in the team improves the performance of batsmen, but not that of bowlers. Our work emphasizes how individual endeavours and team dynamics interconnect and influence collective outcomes in sports.

Abstract
The demands of professional tennis, including physical and psychological aspects, contribute to the frequency of retirements at elite levels of the sport. The aim of this study was to analyze epidemiological patterns and risk factors associated with retirements in previous ATP and WTA Tour tournaments. A retrospective cohort study was conducted. This study focused on previous ATP and WTA Tour tournaments. The ATP database encompassed 584,806 matches, while the WTA database included 267,380 matches. To assess retirements, potential risk factors such as playing surface, tournament category, match round, and player age were analyzed. Incidence rates were calculated for the period between 1978-2019 for men and 1994-2018 for women. The overall incidence rate was 1.56 (95%CI: 1.54, 1.59) and 1.36 (95%CI: 1.33, 1.39) retirements per 1000 games played in male and female competitions, respectively. Retirements increased over the years. Higher incidence rates were observed on hard (1.59 [95%CI: 1.56, 1.63] and 1.39 [95%CI: 1.34, 1.44]) and clay (1.60 [95%CI: 1.57, 1.63] and 1.36 [95%CI: 1.32, 1.41]) compared to grass courts (0.79 [95%CI: 0.65, 0.94] and 1.06 [95%CI: 0.88, 1.27]). Risk factors differed by gender, with tournament category significant in males (IRR: 1.23 [95%CI: 1.19, 1.28] in ITF vs ATP) and match round in females (IRR: 0.92 [95%CI: 0.88, 0.98] in preliminary vs final). This study provides valuable insights for coaches, players, support teams, and epidemiologists regarding retirements and associated risk factors in previous ATP and WTA Tour tournaments, contributing to injury prevention strategies.

Abstract
OBJECTIVE Adequate conditioning results from various physical, environmental, and psychological factors in sports activities. In this study, we aimed to clarify the concurrence and relevance of injuries, psychological problems, and sleep disturbance in university football (soccer) players. Biomechanical characteristics and risk factors for those injuries were also investigated. METHODS Overall, 1,084 university football players participated in this cross-sectional study using a web-based health history questionnaire. Assessments were made via the presence of injuries for physical problems, the Athlete Psychological Strain Questionnaire (APSQ) for psychological problems, and the Athlete Sleep Screening Questionnaire (ASSQ) for sleep difficulties. RESULTS There were 200 (19%) athletes with injuries; 413 (38%) of these were APSQ-positive, 246 (23%) were ASSQ-positive, and 468 (43%) athletes had no physical, psychological, or sleep problems. APSQ-positive respondents were significantly more likely to have a current injury than those who were APSQ-negative. No significant difference was observed between the number of ASSQ-positive and -negative respondents and current injuries. Those with sleep problems were significantly more likely to have psychological problems. CONCLUSION More than 60% of university football players had one or more physical, psychological, or sleep problems. Players may have co-occurring problems, and it is important to address them for these athletes to reach peak performance.

Abstract
ABSTRACT Previous studies involving injury surveillance in badminton players have used nonstandardized injury definitions and data collection methodologies. The purpose of this study was to apply a Delphi method to (1) reach a consensus on an injury definition in badminton and (2) develop a standardized badminton injury report form. An Injury Consensus Group was established under the auspices of the Badminton World Federation, and initial injury definitions and injury report form were developed. An internal panel was formed from the Injury Consensus Group, and an external panel was selected based on a combination of profession, experience in the field, sport-specific knowledge/expertise, and geographical location to obtain a widely representative sample. Through 2 rounds of voting by the external panel, consensus was reached on both the definition of an injury in badminton and a standardized injury report form. The agreed injury definition was "Any physical injury sustained by a player during a match or training regardless if further diagnostic tests were done or if playing time was lost" and the injury report form contained the following 7 sections: Injury record, Diagnosis, Injury mechanism, Regarding pain, Pain and return to play/training after injury, Grade of severity, and Recurrence. We recommend the use of the definitions and methods presented in this consensus statement for the reporting of injury in all international and domestic badminton players. This should make future injury surveillance reports directly comparable and hence more informative in recognizing trends over time and differences between countries.

Abstract
Published injury rates amongst elite and club-level youth cricketers highlight the need to implement injury risk-reducing strategies amongst the youth cricketing population. Data from sports injury surveillance systems are a prerequisite for the development and evaluation of strategies to reduce injury risk. Therefore, collecting injury surveillance data is a positive move towards reducing injuries in cricket. In South Africa, a systematic, standardised, evidence-informed injury surveillance system currently does not exist for community levels of play, namely, in cricket-playing high schools and cricket clubs. Although injury surveillance systems exist at elite levels, the obvious differences in elite versus community cricket settings mean that these systems cannot be implemented in their current form at community-level cricket. An innovative model is required to implement an injury surveillance system in community cricket.

Abstract
OBJECTIVE The objective of the review was to describe the incidence and prevalence of injuries among female cricket players of all ages, participating in all levels of play. INTRODUCTION Cricket, a bat-and-ball sport, is becoming popular among women of all ages and abilities worldwide. However, cricket participation carries a risk of injury. Injuries negatively affect sport participation, performance, and short- and long-term health and well-being. Injury prevention, therefore, is the key to safe, long-term cricket participation as a physical activity goal. Epidemiological data are needed to underpin evidence-based injury-prevention strategies. INCLUSION CRITERIA Studies reporting incidence and prevalence of injuries in female cricket players of all ages, participating in all levels of play, were included in this review, including studies that report data by sex or by sport. Studies without enough data to calculate prevalence or incidence, that do not distinguish female injury data from males', that focus on athletes participating in other sports, or that focus on case studies were excluded. METHODS A systematic review and meta-analyses were conducted according to the JBI and PRISMA 2020 guidelines. MEDLINE, SPORTDiscus, Physiotherapy Evidence Database (PEDro), EBSCO MasterFILE Premier, EBSCO CINAHL Complete, ProQuest Health and Medical Complete, Scopus, and Science Direct were systematically searched from inception to August 2021. Additionally, Cochrane Controlled Trials Register and ClincalTrail.gov were searched. EBSCO MegaFile Premier (EBSCO), OpenGrey (SIGLE), WorldCat, Grey Matters, Grey Literature, and Google Scholar databases were searched for gray literature. Full-text articles that met the inclusion criteria were critically appraised using JBI-tools, and were extracted and synthesized in narrative summary and tabular forms. Three meta-analyses were conducted: injury incidence rate, injury prevalence proportions, and injury incidence proportions. Heterogeneity was assessed using the I2 statistic and the random-effects model. RESULTS Of the 7057 studies were identified and only 4256 screened after duplicates removed, 23 studies met the inclusion criteria. Risk of bias was low for 21 studies. The injury incidence rate for elite cricket was 71.9 (SE 21.3, 95% CI 30.2-113.6) injuries per 1000 player hours, time-loss injury incidence rate was 13.3 (SE 4.4, 95% CI 4.6-22.0) injuries per 1000 player hours, and non-time-loss injury incidence rate was 58.5 (SE 16.9, 95% CI 25.6-91.7) injuries per 1000 player hours. The injury prevalence proportions for community to elite cricket was 65.2% (SE 9.3, 95% CI 45.7-82.3) and injury prevalence proportions for community cricket was 60% (SE 4.5, 95% CI 51.1-68.6). The injury incidence proportions for community cricket was 5.6 (SE 4.4, 95% CI 0.1-18.3) injuries per 10,000 participants. Elite cricket players were more frequently injured than community cricket players. The most prevalent body regions injured were the shoulder and knee, and most were sustained by fast bowlers. Injuries to the hand, wrist, and fingers had the highest incidence and were most sustained by fielders. CONCLUSIONS The study's findings can help stakeholders (including players, coaches, clinicians, and policymakers) make informed decisions about cricket participation by informing and implementing strategies to promote cricket as a vehicle for positive public health outcomes. This review also identified gaps in the available evidence base and addressing these through future research would enhance women's cricket as a professional sport.

Abstract
This systematic review was conducted to identify the incidence, nature and mechanisms of head, neck and facial (HNF) injuries in cricket and the reported use of helmets. Five databases were searched up to 30th November 2020. From peer-reviewed cricket injury studies published in English, studies reporting on HNF cricket injuries as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were selected. Twenty-nine studies were included. HNF injuries had a cumulative total of 794/5,886 injuries equating to 13% of all injuries. Non- specified HNF injuries (n=210, 26%) were the most prevalent type of injury followed by non-specified head injuries (n=130, 16%), other non-specified fractures (n=119, 15%) and concussions (n=60, 8%).The impact of the ball was reported as the most common mechanism for sustaining HNF injuries in cricket. The use of helmet was reported in only three studies (10%). From studies reporting on HNF cricket injuries, facial fractures, and concussions were the most common specified-types of injury. There is little evidence on reporting of HNF cricket injuries as per the international cricket consensus injury definitions, as well as the use of helmets at the time of injury.

Abstract
This study aimed to translate and culturally adapt the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O) and the Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H) into the Japanese context. The validity and reliability of these translated questionnaires examining overuse injuries and health problems among Japanese university athletes were also examined. The translation was performed following an internationally recognized methodology. A total of 145 athletes were tracked over 10 consecutive weeks and four questions were added in the 10th week to examine the questionnaires’ content validity. Test-retest analysis for reliability was performed 24–72 hours after the 10th week of registration. Internal consistency was determined by calculating Cronbach’s a during the cohort study. No major disagreements were found in the translation process. The translated questionnaires had high acceptance and compliance, with an average response rate of over 80% throughout the 10-week cohort study. Most participants reported that the questionnaires were not difficult to complete, there were no items they wanted to change or add, and that the web-based technique worked effectively. Good test-retest reliability and high internal consistency was observed in the translated questionnaires. The translated questionnaires were found to be valid, reliable, and acceptable for medically monitoring Japanese athletes.

Abstract
OBJECTIVES Cricket is a popular sport enjoyed worldwide. Injuries in cricket are not well understood at community level but are important to understand for prevention to ensure the game continues to be enjoyed safely. This systematic review was designed to assess the quality of data collection and reporting, and to summarise the injury data, in studies of community cricket players. DESIGN Systematic review. METHODS Nine databases were searched to November 2018 using the terms "cricket*" and "injur*". A nine-item critical appraisal and three-item likelihood-of-bias evaluation was conducted on included studies. Data completeness was evaluated against recommendations in the international cricket consensus statement for recording/reporting injury and the Australian Sports Injury Data Dictionary (ASIDD). Descriptive injury data (n,%) are presented in tabular format for different subgroups (activity, position, population). RESULTS Thirteen studies were included, of which eight were rated as unclear, one as high and three having a low likelihood-of-bias. The mean score for completeness of data against the consensus statement was 3.5/10 (95%C.I. 2.8-4.2). The mean score for completeness of data against the ASIDD was 4.4/6 (95%C.I. 3.9-5.0). Bruising and inflammation was the most common injury in junior cricket. Stress fractures were most common in studies of bowlers. Where studies included all activities, batting accounted for most injuries (7-49%). CONCLUSIONS The included studies inconsistently addressed recommended items for injury surveillance in community sport and cricket. Most studies focused on junior levels or adolescent bowlers, with bruising/inflammation and stress fractures being most common, respectively.

Abstract
Injury and illness surveillance, and epidemiological studies, are fundamental elements of concerted efforts to protect the health of the athlete. To encourage consistency in the definitions and methodology used, and to enable data across studies to be compared, research groups have published 11 sport-specific or setting-specific consensus statements on sports injury (and, eventually, illness) epidemiology to date. Our objective was to further strengthen consistency in data collection, injury definitions and research reporting through an updated set of recommendations for sports injury and illness studies, including a new Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist extension. The IOC invited a working group of international experts to review relevant literature and provide recommendations. The procedure included an open online survey, several stages of text drafting and consultation by working groups and a 3-day consensus meeting in October 2019. This statement includes recommendations for data collection and research reporting covering key components: defining and classifying health problems; severity of health problems; capturing and reporting athlete exposure; expressing risk; burden of health problems; study population characteristics and data collection methods. Based on these, we also developed a new reporting guideline as a STROBE Extension-the STROBE Sports Injury and Illness Surveillance (STROBE-SIIS). The IOC encourages ongoing in- and out-of-competition surveillance programmes and studies to describe injury and illness trends and patterns, understand their causes and develop measures to protect the health of the athlete. Implementation of the methods outlined in this statement will advance consistency in data collection and research reporting.

Abstract
Objectives The aim was to identify and describe outcomes from original published studies that present the number, nature, mechanism and severity of medically treated injuries sustained in community-level cricket. Design Systematic review. Methods Nine databases were systematically searched to December 2019 using terms "cricket*" and "injur*". Original, peer-reviewed studies reporting injury for at least one injury descriptor (body region, nature of injury and/or mechanism of injury) in community-level cricketers of all ages were included. Qualitative synthesis, critical appraisal and descriptive summary results are reported within the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Results Six studies were included: five reported hospital-treated data and one reported insurance claims data. Two had a low risk of bias. In hospital-based studies, fractures were the most frequent injury type. Upper and lower limb injuries (age ≥15 years) and injuries to the head (age <15 years) were the most common body region injured. Being struck by the ball was the most common mechanism for injury presenting to hospitals. Children were also commonly struck by equipment. One study using insurance claims data reported soft tissue injuries as the main of injury type. Conclusion Hospital treatment data were most prominent, which emphasised injuries of a more serious nature or requiring acute care. These injuries were primarily fractures, dislocation/sprain and strains, bruising and open wounds with the majority resulting from players being struck by the ball. Research into whether properly fitted protective equipment, at an approved standard, is worn and is effective, is recommended.

Abstract
BACKGROUND Injury and illness surveillance, and epidemiological studies, are fundamental elements of concerted efforts to protect the health of the athlete. To encourage consistency in the definitions and methodology used, and to enable data across studies to be compared, research groups have published 11 sport- or setting-specific consensus statements on sports injury (and, eventually, illnesses) epidemiology to date. OBJECTIVE To further strengthen consistency in data collection, injury definitions, and research reporting through an updated set of recommendations for sports injury and illness studies, including a new Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist extension. STUDY DESIGN Consensus statement of the International Olympic Committee (IOC). METHODS The IOC invited a working group of international experts to review relevant literature and provide recommendations. The procedure included an open online survey, several stages of text drafting and consultation by working groups, and a 3-day consensus meeting in October 2019. RESULTS This statement includes recommendations for data collection and research reporting covering key components: defining and classifying health problems, severity of health problems, capturing and reporting athlete exposure, expressing risk, burden of health problems, study population characteristics, and data collection methods. Based on these, we also developed a new reporting guideline as a STROBE extension-the STROBE Sports Injury and Illness Surveillance (STROBE-SIIS). CONCLUSION The IOC encourages ongoing in- and out-of-competition surveillance programs and studies to describe injury and illness trends and patterns, understand their causes, and develop measures to protect the health of the athlete. The implementation of the methods outlined in this statement will advance consistency in data collection and research reporting.

Abstract
Background To commence injury prevention efforts, it is necessary to understand the magnitude of the injury problem. No systematic reviews have yet investigated the extent of injuries in field hockey, despite the popularity of the sport worldwide. Objective Our objective was to describe the rate and severity of injuries in field hockey and investigate their characteristics. Methods We conducted electronic searches in PubMed, Embase, SPORTDiscus, and CINAHL. Prospective cohort studies were included if they were published in English in a peer-reviewed journal and observed all possible injuries sustained by field hockey players during the period of the study. Results The risk of bias score of the 22 studies included ranged from three to nine of a possible ten. In total, 12 studies (55%) reported injuries normalized by field hockey exposure. Injury rates ranged from 0.1 injuries (in school-aged players) to 90.9 injuries (in Africa Cup of Nations) per 1000 player-hours and from one injury (in high-school women) to 70 injuries (in under-21 age women) per 1000 player-sessions. Studies used different classifications for injury severity, but—within studies—injuries were included mostly in the less severe category. The lower limbs were most affected, and contusions/hematomas and abrasions were common types of injury. Contact injuries are common, but non-contact injuries are also a cause for concern. Conclusions Considerable heterogeneity meant it was not possible to draw conclusive findings on the extent of the rate and severity of injuries. Establishing the extent of sports injury is considered the first step towards prevention, so there is a need for a consensus on injury surveillance in field hockey.

Abstract
OBJECTIVE Scientific knowledge about symptoms of common mental disorders in professional cricket is non-existent. Consequently, the aims of the study were to determine the prevalence and the 6 months incidence of symptoms of common mental disorders (CMD: distress, anxiety/depression, sleep disturbance, adverse alcohol use) among current and former professional cricketers and to explore the association of potential stressors (significant injury, surgery, adverse life events, career dissatisfaction) and CMD. METHODS An observational prospective cohort study with a follow-up period of 6 months was conducted among current and former professional cricketers from South Africa. Using validated questionnaires to assess symptoms of common mental disorders as well as several stressors, an electronic questionnaire was set up and distributed by the South African Cricketers Association (SACA). RESULTS A total of 116 participants enrolled at baseline (overall response rate of 33%) and 76 of those participants completed the 6 month follow-up (follow up rate of 66%). The prevalence of symptoms of CMD in current professional cricketers was 38% for distress, 38% for sleep disturbance, 37% for anxiety/depression and 26% for adverse alcohol use. Among former professional cricketers, baseline prevalence as was 26% for distress, 24% for anxiety/depression, 21% for sleep disturbance and 22% for adverse alcohol use. Career dissatisfaction led to an increased risk of distress, anxiety/depression and sleep disturbance in current professional cricketers. Surgeries and adverse life events led to an increase in reported symptoms of distress and anxiety/depression in current professional cricketers. CONCLUSIONS It was concluded that symptoms of CMD are prevalent in both current and former professional cricketers and the association with surgery, adverse life events and cricket career dissatisfaction may provide some insight into possible mechanisms.

Abstract
BACKGROUND T20 (Twenty20 or 20 over) cricket has emerged in the last decade as the most popular form of cricket (in terms of spectator attendances). International consensus cricket definitions, first published in 2005, were updated in 2016 to better reflect the rise to prominence of T20 cricket. METHODS Injury incidence and prevalence rates were calculated using the new international methods and units for elite senior male Australian cricketers over the past decade (season 2006-2007 to season 2015-2016 inclusive). RESULTS Over the past 10 seasons, average match injury incidence, for match time-loss injuries, was 155 injuries/1,000 days of play, with the highest daily rates in 50-over cricket, followed by 20-over cricket and First-Class matches. Annual injury incidence was 64 injuries/100 players per season, and average annual injury prevalence was 12.5% (although fast bowlers averaged 20.6%, much higher than other positions). The most common injury was the hamstring strain (seasonal incidence 8.7 injuries/100 players per season). The most prevalent injury was lumbar stress fractures (1.9% of players unavailable at all times owing to these injuries, which represents 15% of all missed playing time). DISCUSSION The hamstring strain has emerged from being one of the many common injuries in elite cricket a decade ago to being clearly the most common injury in the sport at the elite level. This is presumably in association with increased T20 cricket. Lumbar stress fractures in fast bowlers are still the most prevalent injury in the sport of cricket at the elite level, although these injuries are more associated with high workloads arising from the longer forms of the game. Domestic and international matches have very similar match injury incidence rates across the formats, but injury prevalence is higher in international players as they play for most of the year without a substantial off-season.

Abstract
BACKGROUND AND AIMS Data from sports injury surveillance systems are a prerequisite to the development and evaluation of injury prevention strategies. This review aimed to identify ongoing sports injury surveillance systems and determine whether there are gaps in our understanding of injuries in certain sport settings. A secondary aim was to determine which of the included surveillance systems have evaluated the quality of their data, a key factor in determining their usefulness. METHODS A systematic search was carried out to identify (1) publications presenting methodological details of sports injury surveillance systems within clubs and organisations; and (2) publications describing quality evaluations and the quality of data from these systems. Data extracted included methodological details of the surveillance systems, methods used to evaluate data quality, and results of these evaluations. RESULTS Following literature search and review, a total of 15 sports injury surveillance systems were identified. Data relevant to each aim were summarised descriptively. Most systems were found to exist within professional and elite sports. Publications concerning data quality were identified for seven (47%) systems. Validation of system data through comparison with alternate sources has been undertaken for only four systems (27%). CONCLUSIONS This review identified a shortage of ongoing injury surveillance data from amateur and community sport settings and limited information about the quality of data in professional and elite settings. More surveillance systems are needed across a range of sport settings, as are standards for data quality reporting. These efforts will enable better monitoring of sports injury trends and the development of sports safety strategies.

Abstract
Cricket was the first sport to publish recommended methods for injury surveillance in 2005. Since then, there have been changes to the nature of both cricket and injury surveillance. Researchers representing the major cricket playing nations met to propose changes to the previous recommendations, with an agreed voting block of 14. It was decided that 10 of 14 votes (70%) were required to add a new definition element and 11 of 14 (80%) were required to amend a previous definition. In addition to the previously agreed 'Match time-loss' injury, definitions of 'General time-loss', 'Medical presentation', 'Player-reported' and 'Imaging-abnormality' injuries are now provided. Further, new injury incidence units of match injuries per 1000 player days, and annual injuries per 100 players per year are recommended. There was a shift towards recommending a greater number of possible definitions, due to differing contexts and foci of cricket research (eg, professional vs amateur; injury surveillance systems vs specific injury category studies). It is recommended that researchers use and report as many of the definitions as possible to assist both comparisons between studies within cricket and with those from other sports.

Abstract
Sports participation is a major ally for the promotion of physical activity. However, sports injuries are important adverse effects of sports participation and should be monitored in sports populations. The purpose of this paper is to review the basic concepts of injury monitoring and discuss the implementation of these concepts in practice. The aspects discussed are: (1) sports injury definition; (2) classification of sports injuries; (3) population at risk, prevalence, and incidence; (4) severity measures; (5) economic costs; (6) systems developed to monitor sports injuries; and (7) online technology. Only with reliable monitoring systems applied in a continuous and long-term manner will it be possible to identify the burden of injuries, to identify the possible cases at an early stage, to implement early interventions, and to generate data for sports injury prevention. The implementation of sports injuries monitoring systems in practice is strongly recommended.

Abstract
OBJECTIVE To assess workload-related risk factors for injuries to particular tissue types in cricket fast bowlers. DESIGN 235 fast bowlers who bowled in 14600 player innings over a period of 15 years were followed in a prospective cohort risk factor study to compare overs bowled in each match (including preceding workload patterns) and injury risk in the 3-4 weeks subsequent to the match. Injuries were categorised according to the affected tissue type as either: bone stress, tendon injuries, muscle strain or joint injuries. Workload risk factors were examined using binomial logistic regression multivariate analysis, with a forward stepwise procedure requiring a significance of <0.05. RESULTS High acute match workload and high previous season workload were risk factors for tendon injuries, but high medium term (3-month workload) was protective. For bone stress injuries, high medium term workload and low career workload were risk factors. For joint injuries, high previous season and career workload were risk factors. There was little relationship between muscle injury and workload although high previous season workload was slightly protective. CONCLUSIONS The level of injury risk for some tissue types varies in response to preceding fast bowling workload, with tendon injuries most affected by workload patterns. Workload planning may need to be individualised, depending on individual susceptibility to various injury types. This study supports the theory that tendons are at lowest risk with consistent workloads and susceptible to injury with sudden upgrades in workload. Gradual upgrades are recommended, particularly at the start of a bowler's career to reduce the risk of bone stress injury.

[PMID: 25245426 DOI: 10.1016/j.jsams.2014.09.002] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2014] [Revised: 07/18/2014] [Accepted: 09/01/2014] [Indexed: 10/24/2022]
Abstract
OBJECTIVES This study examined whether high match fast bowling workloads in the short to medium term were associated with increased bowling injury rates. DESIGN Prospective cohort study. METHODS Over a 15 year period, workload patterns for 235 individual fast bowlers during time periods from 5 to 26 days were examined to consider whether there was an increased injury rate during the month (28 days) subsequent to the workload. RESULTS Fast bowlers who bowled more than 50 match overs in a 5 day period had a significant increase in injury over the next month compared to bowlers who bowled 50 overs or less RR 1.54 (95% CI 1.04-2.29). For periods ranging from 12 to 26 days, there was no statistically-significant increase in injury over the next month from exceeding thresholds of certain amounts of overs, although bowlers who bowled more than 100 overs in 17 days had a non-significant increase in injury over the next month RR 1.78 (95% CI 0.90-3.50). CONCLUSION There were no statistically-significant increases in subsequent injury risk for high workloads for periods of 12-26 days, although exceeding 100 overs in 17 days (or less) was associated with higher injury rates. Compression of cricket fixtures is likely to have only a minimal contribution to increased fast bowling injury rates being seen in the T20 era (along with sudden workload increases due to transferring between forms of the game, which has been previously established as a major contributor).

Inj Epidemiol 2014; 1:19. [PMID: 26613071 PMCID: PMC4648950 DOI: 10.1186/s40621-014-0019-y] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2014] [Accepted: 06/28/2014] [Indexed: 11/10/2022] Open
Abstract
Background Previous research aimed at improving injury surveillance standards has focused mainly on issues of data quality rather than upon the implementation of surveillance systems. There are numerous settings where injury surveillance is not mandatory and having a better understanding of the barriers to conducting injury surveillance would lead to improved implementation strategies. One such setting is community sport, where a lack of available epidemiological data has impaired efforts to reduce injury. This study aimed to i) evaluate use of an injury surveillance system following delivery of an implementation strategy; and ii) investigate factors influencing the implementation of the system in community sports clubs. Methods A total of 78 clubs were targeted for implementation of an online injury surveillance system (approximately 4000 athletes) in five community Australian football leagues concurrently enrolled in a pragmatic trial of an injury prevention program called FootyFirst. System implementation was evaluated quantitatively, using the RE-AIM framework, and qualitatively, via semi-structured interviews with targeted-users. Results Across the 78 clubs, there was 69% reach, 44% adoption, 23% implementation and 9% maintenance. Reach and adoption were highest in those leagues receiving concurrent support for the delivery of FootyFirst. Targeted-users identified several barriers and facilitators to implementation including personal (e.g. belief in the importance of injury surveillance), socio-contextual (e.g. understaffing and athlete underreporting) and systems factors (e.g. the time taken to upload injury data into the online system). Conclusions The injury surveillance system was implemented and maintained by a small proportion of clubs. Outcomes were best in those leagues receiving concurrent support for the delivery of FootyFirst, suggesting that engagement with personnel at all levels can enhance uptake of surveillance systems. Interview findings suggest that increased uptake could also be achieved by educating club personnel on the importance of recording injuries, developing clearer injury surveillance guidelines, increasing club staffing and better remunerating those who conduct surveillance, as well as offering flexible surveillance systems in a range of accessible formats. By increasing the usage of surveillance systems, data will better represent the target population and increase our understanding of the injury problem, and how to prevent it, in specific settings.

Abstract
Cricket has over the years gained much popularity in Asia, thus the number of cricket players has also grown in tandem. However, cricket players are not as fortunate as other athletes as they do not always have a standard cricket infrastructure to practice; therefore, the injury prevalence is expected to be high. Unfortunately, very few studies have been conducted to investigate the nature and pattern of cricket injuries prevalent to cricketers in this region. Therefore, a prospective cohort injury surveillance study was conducted during the Asian Cricket Council (ACC) Under-19 Elite Cup held in June 2013 in order to gather more data on the type of injuries sustained by cricket players. Overall, 31 injuries occurred to 28 players throughout the tournament, of which 7 injuries happened during practice sessions. The overall injury incidence rate (IIR) was 292.0 per 10,000 player hours (95% CI 176.9-407.1) and 10.4 per 10,000 balls faced and 2.6 per 1000 overs bowled delivered during batting and bowling, respectively. Injuries to the lower limb (IIR: 146; 95% CI 1.8-98.2) were the most frequent, followed by injuries to the upper limb (97.3;95% CI 30.2-164.5) and to the trunk and back (IIR: 36.5;95% CI 0.0-77.7). Sprain/strains (IIR 109.5;95% CI 38.4-180.7) to muscle/tendon and joint/ligament were the most commonly reported nature of injury. This is the first study investigating injury incidence among the players of the ACC. It provides an overview of injuries sustained by elite players' under-19 years of age from 10 Asian countries. The overall IIR is similar to earlier studies conducted in well-established cricket playing nations.

Abstract
BACKGROUND Before preventive actions can be suggested for sports injuries at the national level, a solid surveillance system is required in order to study their epidemiology, risk factors and mechanisms. There are guidelines for sports injury data collection and classifications in the literature for that purpose. In Sweden, 90% of all athletes (57/70 sports federations) are insured with the same insurance company and data from their database could be a foundation for studies on acute sports injuries at the national level. OBJECTIVE To evaluate the usefulness of sports injury insurance claims data in sports injury surveillance at the national level. METHOD A database with 27 947 injuries was exported to an Excel file. Access to the corresponding text files was also obtained. Data were reviewed on available information, missing information and dropouts. Comparison with ASIDD (Australian Sports Injury Data Dictionary) and existing consensus statements in the literature (football (soccer), rugby union, tennis, cricket and thoroughbred horse racing) was performed in a structured manner. RESULT Comparison with ASIDD showed that 93% of the suggested data items were present in the database to at least some extent. Compliance with the consensus statements was generally high (13/18). Almost all claims (83%) contained text information concerning the injury. CONCLUSIONS Relatively high-quality sports injury data can be obtained from a specific insurance company at the national level in Sweden. The database has the potential to be a solid base for research on acute sports injuries in different sports at the national level.

Abstract
Objective Sports injuries are often recurrent and there is wide recognition that a subsequent injury (of either the same or a different type) can be strongly influenced by a previous injury. Correctly categorising subsequent injuries (multiple, recurrent, exacerbation or new) requires substantial clinical expertise, but there is also considerable value in combining this expertise with more objective statistical criteria. This paper presents a new model, the subsequent injury categorisation (SIC) model, for categorising subsequent sports injuries that takes into account the need to include both acute and overuse injuries and ten different dependency structures between injury types. Methods The suitability of the SIC model was demonstrated with date ordered sports injury data from a large injury database from community Australian football players over one playing season. A subsequent injury was defined to have occurred in the subset of players with two or more reported injuries. Results 282 players sustained 469 subsequent injuries of which 15.6% were coded to categories representing injuries that were directly related to previous index injuries. This demonstrates that players can sustain a number of injuries over one playing season. Many of these will be unrelated to previous injuries but subsequent injuries that are related to previous injury occurrences are not uncommon. Conclusion The handling of subsequent sports injuries is a substantial challenge for the sports medicine field—both in terms of injury treatment and in epidemiological research to quantify them. Application of the SIC model allows for multiple different injury types and relationships within players, as well as different index injuries.

Abstract
BACKGROUND Injury surveillance is the cornerstone of effective injury management. However, to date no studies using recommended methods and involving multiple nations have been conducted within International Cricket. AIM To conduct injury surveillance across multiple teams during the ICC Cricket World Cup 2011. METHODS An electronic system, based on the guidelines for injury surveillance in international cricket, was used to record all new injury episodes was used for data collection. RESULTS Twenty-three time-loss and 97 non-time-loss injuries were recorded. The injury incidence was 3.7/100 player-days (0.7 time-loss and 3.0 non-time-loss) with time-loss incidence being; for match injury 20.1/1000 player-days, bowling injury 3.3/100 bowling days and batting injuries 2.2/10,000 balls faced. Thigh muscle strain and medical illness were the diagnoses with the highest incidence. Fast bowlers, slow bowlers and batters all had a similar injury prevalence of approximately 5%. The bowling delivery stride was the activity that resulted in the greatest lost time. CONCLUSIONS This is the first study to use recommended injury surveillance guidelines to reporting injury rates across multiple teams at a major cricket tournament. Non-time-loss injury incidence appears relatively high and further study of the effect on performance and progression to subsequent time-loss is required. Fast bowler injury prevalence rates are lower than reported elsewhere, however this may be due to the nature of the tournament and match format, which is likely to impose a lower relative workload. In future, data from all competing teams over all formats of the game (Twenty20, ODI and Tests) needs to be analysed to effectively inform injury prevention research and practice.

Abstract
STUDY DESIGN Prospective, descriptive single-cohort study. OBJECTIVE To assess the incidence and severity of injuries to a professional ballet company over 1 year. METHODS Data for an elite-level ballet company of 52 professional dancers were collected by an in-house medical team using a time-loss injury definition. RESULTS A total of 355 injuries were recorded, with an overall injury incidence of 4.4 injuries per 1000 hours (female, 4.1; male, 4.8; P>.05) and a mean of 6.8 injuries per dancer (female, 6.3; male, 7.3; P>.05). Mean injury severity was 7 days (female, 4; male, 9; P<.05). Most injuries were classified as overuse (64%; female, 68%; male, 60%; P>.05); mean severity of injury was 3 days for females and 9 days for males (P<.05). The percentage of traumatic injuries was 32% for females and 40% for males (P<.05); the corresponding severity was 6 and 10 days, respectively (P<.05). CONCLUSION The relatively high number of injuries reported and the resulting loss of dance time support the need to introduce interventions to reduce the risk of injury in professional dancers.J Orthop Sports Phys Ther 2012;42(9):781-790.

Abstract
This paper describes injury (circumstances and type) experienced by sub-populations at all levels of cricket and, where possible, the type of protective equipment used. The sample differs to that generally examined in the literature in that it is not restricted to evaluation of elite and professional players only. Over a 6-year period (2000-2005), 498 cases were identified. The average age of injury was 27 years and 86% of those injured were male. The population incidence rate was 2.3 per 100,000 per year, and participation incidence rate 39 per 100,000 per year. Over all age groups upper limb (36%) and lower limb (31%) were most commonly injured. Fracture was the main type of injury. Differences among age groups were identified. Children (<10 years) most commonly suffered head injury (contact with the bat); 10-19 year olds, head, upper and lower limb injury (in similar proportions) generally from contact with bat/ball; those over 20 years mainly had upper and lower limb injuries. Contact with the bat/ball was the dominant mechanism of injury for those under 50 years of age while overexertion, strenuous or repetitive movements, slips and falls were the mechanisms for those over 50. The large number of head injuries to children is of concern and both these, and the substantial number of injuries to the hand/phalanges (63% of all upper limb injuries), are important targets for injury prevention. The difference in injury patterns between children and adults is indicative of a need to develop, and use, different types of PPE at different skill/age levels.

Abstract
The Orchard Sports Injury Classification System (OSICS) is one of the world's most commonly used systems for coding injury diagnoses in sports injury surveillance systems. Its major strengths are that it has wide usage, has codes specific to sports medicine and that it is free to use. Literature searches and stakeholder consultations were made to assess the uptake of OSICS and to develop new versions. OSICS was commonly used in the sports of football (soccer), Australian football, rugby union, cricket and tennis. It is referenced in international papers in three sports and used in four commercially available computerised injury management systems. Suggested injury categories for the major sports are presented. New versions OSICS 9 (three digit codes) and OSICS 10.1 (four digit codes) are presented. OSICS is a potentially helpful component of a comprehensive sports injury surveillance system, but many other components are required. Choices made in developing these components should ideally be agreed upon by groups of researchers in consensus statements.

Abstract
This study analyzes injuries occurring prospectively in Australian men’s cricket at the state and national levels over 11 seasons (concluding in season 2008–09). In the last four of these seasons, there was more cricket played, with most of the growth being a new form of the game – Twenty20 cricket. Since the introduction of a regular Twenty20 program, injury incidence rates in each form of cricket have been fairly steady. Because of the short match duration, Twenty20 cricket exhibits a high match injury incidence, expressed as injuries per 10,000 hours of play. Expressed as injuries per days of play, Twenty20 cricket injury rates compare more favorably to other forms of cricket. Domestic level Twenty20 cricket resulted in 145 injuries per 1000 days of play (compared to 219 injuries per 1000 days of domestic one day cricket, and 112 injuries per 1000 days of play in first class domestic cricket). It is therefore recommended that match injury incidence measures be expressed in units of injuries per 1000 days of play. Given the high numbers of injuries which are of gradual onset, seasonal injury incidence rates (which typically range from 15–20 injuries per team per defined ‘season’) are probably a superior incidence measure. Thigh and hamstring strains have become clearly the most common injury in the past two years (greater than four injuries per team per season), perhaps associated with the increased amount of Twenty20 cricket. Injury prevalence rates have risen in conjunction with an increase in the density of the cricket calendar. Annual injury prevalence rates (average proportion of players missing through injury) have exceeded 10% in the last three years, with the injury prevalence rates for fast bowlers exceeding 18%. As the amount of scheduled cricket is unlikely to be reduced in future years, teams may need to develop a squad rotation for fast bowlers, similar to pitching staff in baseball, to reduce the injury rates for fast bowlers. Consideration should be given to rule changes which may reduce the impact of injury. In particular, allowing the 12th man to play as a full substitute in first class cricket (and therefore take some of the bowling workload in the second innings) would probably reduce bowling injury prevalence in cricket.

Abstract
Objective To assess whether a history of lumbar stress fracture in pace bowlers in cricket is a risk factor for lower limb muscle strains. Methods This was a prospective cohort risk factor study, conducted using injury data from contracted first class pace bowlers in Australia during seasons 1998–1999 to 2008–2009 inclusive. There were 205 pace bowlers, 33 of whom suffered a lumbar stress fracture when playing first class cricket. Risk ratios ([RR] with 95% confidence intervals[CI]) were calculated to compare the seasonal incidence of various injuries between bowlers with a prior history of lumbar stress fracture and those with no history of lumbar stress fracture. Results Risk of calf strain was strongly associated with prior lumbar stress fracture injury history (RR = 4.1; 95% CI: 2.4–7.1). Risks of both hamstring strain (RR = 1.5; 95% CI: 1.03–2.1) and quadriceps strain (RR = 2.0; 95% CI: 1.1–3.5) were somewhat associated with history of lumbar stress fracture. Risk of groin strain was not associated with history of lumbar stress fracture (RR = 0.7; 95% CI: 0.4–1.1). Other injuries showed little association with prior lumbar stress fracture, although knee cartilage injuries were more likely in the non-stress fracture group. Conclusion Bony hypertrophy associated with lumbar stress fracture healing may lead to subsequent lumbar nerve root impingement, making lower limb muscle strains more likely to occur. Confounders may be responsible for some of the findings. In particular, bowling speed is likely to be independently correlated with risk of lumbar stress fracture and risk of muscle strain. However, as the relationship between lumbar stress fracture history and calf strain was very strong, and that there is a strong theoretical basis for the connection, it is likely that this is a true association.

[PMID: 20031485 DOI: 10.1016/j.jsams.2009.10.489] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2009] [Revised: 10/29/2009] [Accepted: 10/30/2009] [Indexed: 10/20/2022]
Abstract
Internationally, there is a lack of good quality, prospectively collected injury data reported for junior club cricketers. This study describes injury rates according to age level of play and playing positions in junior community-level club cricketers to identify priorities for prevention. A prospective cohort study was used to monitor injuries in 88 under 12 years (U12), 203 U14 and 120 U16 players from the Ballarat Junior Cricket Association, Australia over the 2007/2008 playing season. Injury rates were calculated per 1000 participations when batting, bowling or fielding in matches and training sessions. Injury rate ratios were used to compare rates across age levels of play and position of play. Overall, 47 injuries were reported. Injury rates increased with age level of play with only one U12 player injured. Match injury rates were 3.57 per 1000 U14 participations versus 4.80 per 1000 U16 participations. Training injury rates were 4.20 per 1000 U14 participations versus 5.11 per 1000 U16 participations. On a proportionate basis, injuries occurred equally to fielders, batters and bowlers. There was a trend towards more injuries occurring while batting and fielding in matches, and more injuries occurring while bowling and batting during training sessions. In conclusion, injury rates in junior cricket players are low, but increase with age level of play. Unlike adult forms of the game, injuries occur to fielders and batters at least as frequently as to bowlers, indicating that preventive strategies need to be developed for all junior players and not just bowlers, as has been the focus previously.

Abstract
BACKGROUND The reported incidence, severity and nature of injuries sustained in tennis vary considerably between studies. While some of these variations can be explained by differences in sample populations and conditions, the main reasons are related to differences in definitions and methodologies employed in the studies. OBJECTIVE This statement aims to review existing consensus statements for injury surveillance in other sports in order to establish definitions, methods and reporting procedures that are applicable to the specific requirements of tennis. DESIGN The International Tennis Federation facilitated a meeting of 11 experts from 7 countries representing a range of tennis stakeholders. Using a mixed methods consensus approach, key issues related to definitions, methodology and implementation were discussed and voted on by the group during a structured one-day meeting. Following this meeting, 2 members of the group collaborated to produce a draft statement, based on the group discussions and voting outcomes. Three revisions were prepared and circulated for comment before the final consensus statement was produced. RESULTS A definition of medical conditions (injuries and illnesses) that should be recorded in tennis epidemiological studies and criteria for recording the severity and nature of these conditions are proposed. Suggestions are made for recording players' baseline information together with recommendations on how medical conditions sustained during match play and training should be reported. CONCLUSIONS The definitions and methodology proposed for recording injuries and illnesses sustained during tennis activities will lead to more consistent and comparable data being collected. The surveillance procedures presented here may also be applicable to other racket sports.

Abstract
BACKGROUND Limited research in cricket bowlers and baseball pitchers has shown a correlation between workload and injury risk. HYPOTHESIS Acute high bowling workload in cricket leads to increased risk of bowling injury in future matches. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS One hundred twenty-nine pace (fast) bowlers who bowled in 2715 player matches over a period of 10 seasons were followed to compare overs bowled in each match and injury risk subsequent to the match. RESULTS Bowlers who bowled more than 50 overs in a match had an injury incidence in the next 21 days of 3.37 injuries per 1000 overs bowled, a significantly increased risk compared with those bowlers who bowled less than 50 overs (relative risk [RR], 1.77; 95% confidence interval [CI]: 1.05-2.98). Bowlers who bowled more than 30 overs in the second inning of a match had a significantly increased injury risk per over bowled in the next 28 days (RR, 2.42; 95% CI: 1.38-4.26). Time periods of less than 21 days or more than 28 days after the match in question did not yield significant differences in injury risk per over bowled between high and low workload bowlers. CONCLUSION High acute workload in cricket fast bowlers may lead to a somewhat delayed increased risk of injury up to 3 to 4 weeks after the acute overload, possibly via a mechanism of damaging immature (repair) tissue. CLINICAL RELEVANCE Cricket fast bowling and possibly baseball pitching workloads require scrutiny not just for acute injuries but also for injury prevention in the subsequent month.

Orchard J, Hoskins W. For debate: consensus injury definitions in team sports should focus on missed playing time. Clin J Sport Med 2007; 17:192-6.

Abstract
OBJECTIVE To compare the most commonly used and proposed injury definitions for surveillance systems in team sports and attempt to assess their suitability for consensus definitions in terms of reliability and functionality. DATA SOURCES The PubMed and SportDiscus databases were searched for papers on team sports that discussed consensus definitions or compared various definitions of injury. DATA SYNTHESIS A continuum between the most broad "tissue damage" definition and the most narrow "match time loss only" definition was developed. RESULTS A "match time loss only" injury definition can be reliably and accurately applied but only captures a small percentage of the total pool of all "tissue damage" injuries. There are some inherent biases in using a match time loss only definition (late season matches, matches with unequal breaks between games), but these are clearly visible. All other definitions improve the volume of data captured but suffer serious theoretical and/or practical flaws with respect to accuracy and reliability. No study using a broad definition has demonstrated good reliability to date (eg, using 2 independent recorders at the same team). CONCLUSION A "match time loss only" injury definition is the most accurate and reliable of those commonly used in team sports. Other injury definitions are broader and may be more appropriate for individual team and specific injury studies. However, a match time loss definition is the most accurate and reliable tool for comparing injury rates at different teams and between different seasons within teams. Hence, we recommend this as the basis for the injury definition in a consensus statement.

Abstract
Injury classification systems are generally used in sports medicine (1) to accurately classify diagnoses for summary studies, permitting easy grouping into parent categories for tabulation and (2) to create a database from which cases can be extracted for research on specific injuries. Clarity is most important for the first purpose, whereas diagnostic detail is particularly important for the second. An ideal classification system is versatile and appropriate for all sports and all data collection scenarios. The Orchard Sports Injury Classification System (OSICS) was developed in 1992 primarily for the first purpose, a specific study examining the incidence of injury at the elite level of football in Australia. As usage of the OSICS expanded into different sports, limitations were noted and therefore many revisions have been made. A recent study found the OSICS-8, whilst superior to the International Classification of Diseases Australian Modification (ICD-10-AM) in both speed of use and 3-coder agreement, still achieved a lower level of agreement than expected. The study also revealed weaknesses in the OSICS-8 that needed to be addressed. A recent major revision resulted in the development of the new 4-character OSICS-10. This revision attempts to improve interuser agreement, partly by including more diagnoses encountered in a sports medicine setting. The OSICS-10 should provide far greater depth in classifications for the benefit of those looking to maintain diagnostic information. It is also structured to easily collapse down into parent classifications for those wanting to preserve basic information only. For those researchers wanting information collected under broader injury headings, particularly those not using fully computerized systems, the simplicity of the OSICS-8 system may still suffice.

Orchard JW, James T, Portus MR. Injuries to elite male cricketers in Australia over a 10-year period. J Sci Med Sport 2006; 9:459-67.

Abstract
This study analyses injuries occurring to Australian male cricketers at the state and national levels over 10 years using recently published international definitions of injury. Data was collected retrospectively for 3 years and then prospectively over the final 7 years. Injury incidence has stayed at a fairly constant level over the 10 years. Injury prevalence has gradually increased over the 10-year period but fell in season 2004-2005. Increasing match scheduling over the 10-year period has probably contributed to the increasing injury prevalence. Fast bowlers miss, through injury, about 16% of all potential playing time, whereas the prevalence rate for all other positions is less than 5%. Some match and schedule-related risks for bowling injury have been noted, including a greater risk of injury in the second innings of first class matches (compared to the first innings), a greater risk of injury in the second game of back-to-back matches and an increased risk of injury in the rare situation of enforcing the follow-on in a test match. The introduction of a boundary rope at all grounds has successfully eliminated the mechanism of injury from collision with fences whilst fielding. Cricket is a much safer sport to play at the elite level for batsmen, fieldsmen, wicketkeepers, and spin bowlers than the football codes, which are the other most popular professional sports in Australia.
