Diving Into the Health Problems of Competitive Divers: A Systematic Review of Injuries and Illnesses in Pre-elite and Elite Diving Athletes.

The Olympic sport of diving involves the competitive disciplines of 3 m springboard and 10 m platform. Although it is generally accepted that lumbar spine injuries are common in diving athletes, the existing literature of health problems in diving athletes remains scarce. To identify the incidence, prevalence, and type of health problems that occur in competitive diving athletes. Medline, EMBASE, SportsDiscus, PsycINFO, and Google Scholar. Studies written in English investigating elite or pre-elite competitive diving (springboard, platform) injuries and/or illnesses were eligible. Two independent reviewers screened for inclusion by title, abstract, and full text in accordance with the eligibility criteria. Systematic review. Level 4. Data extraction was completed by 1 author using a structured form. A second author then independently reviewed and verified the extracted data, any discrepancies were resolved through consensus. The search identified 2554 potential articles, with 28 studies meeting eligibility criteria. The surveillance setting of most studies was restricted to competition-based events, with the reported injury incidence proportion ranging from 2.1% to 22.2%. The reported injury incidence rate ranged from 1.9 to 15.5 per 1000 athlete-exposures. Injuries to the shoulder, lower back/lumbar spine, trunk, and wrist/hand were reported most frequently. The prevalence of low back pain was reported as high as 89% (lifetime), 43.1% (period), and 37.3% (point). The illness incidence proportion ranged from 0.0% to 22.2%, with respiratory and gastrointestinal illness reported most frequently. Up to 1 in 5 diving athletes sustain an injury and/or illness during periods of competition. A reporting bias was observed, with most cohort studies limiting surveillance to short competition-based periods only. This limits the current understanding of the health problems experienced by diving athletes to competition periods only and requires expansion to whole-of-year surveillance.

Time-loss Injuries among Female and Male Spanish Rink Hockey Players.

The present study describes the time-loss injuries among female and male athletes of the Spanish rink hockey league during the 2021/22 season.We performed a retrospective cohort study on time-loss injuries, whereby the athlete is prevented from participating in a training session or game because of the injury.A total of 463 athletes were included, with 326 (70.4%) senior male and 137 (29.6%) female. Two hundred and eighty-two time-loss injuries were recorded, the most common form being muscle injuries (112 episodes, 39.7%), especially those affecting the hip adductor muscles (52 episodes, 46.4% of muscle injuries). Most injuries were classified as mild (1-7 days of time-loss) and the median return-to-play was 9.5 days (range 1-180).Injury patterns were compared according to gender, position and moment: the results showed significant differences between senior males and females, between field players and goalkeepers, as well as between training and game, in terms of injury nature and type. The injury incidence proportion was significantly higher for field players compared to goalkeepers), and senior males had a significantly higher risk than senior females.The present study provides a starting point for studying and preventing injuries in rink hockey athletes.

Epidemiology of Injuries during Judo Tournaments.

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. 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). 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.

Influence of High School Socioeconomic Status on Athlete Injuries during the COVID-19 Pandemic: An Ecological Study.

It is presently unclear how the cessation of high school sport has affected injury incidence at different socioeconomic levels. The COVID-19 pandemic may have disproportionately affected athletes of lower socioeconomic status, potentially increasing injury risk in this population. To 1) Describe athlete injury incidence prior to and during the 2019-2020 and 2020-2021 school years in high school athletes by socioeconomic status; 2) Investigate the association between socioeconomic status and injury incidence in high school athletes. Ecological Study. High schools were matched between the 2019-2020 and 2020-2021 school years. All athletes from all sports were included. High school socioeconomic status was determined by the school district median household income. Socioeconomic strata were defined as <$30,000, $30,000-50,000, $50,001-100,000, and >$100,000. Injury incidence proportion with 95% confidence interval (95% CI) was calculated for each academic year. Mixed effects negative binomial models with robust errors were performed to assess the association between the incidence proportion ratio and high school median household income. Six states and 176 high schools were included (2019-2020: 98,487 athletes; 2020-2021: 72,521 athletes). Injury incidence increased in three of four socioeconomic strata during the 2020-2021 year (<$30,000: 2019-2020: 15.6 (13.1-18.1), 2020-2021: 26.3 (23.1-29.6); $30,000-50,000: 2019-2020: 7.8 (7.1-8.6), 2020-2021: 14.9 (13.8-15.9); $50,001-100,000: 2019-2020: 15.1 (14.7-15.4), 2020-2021: 21.3 (20.9-21.8); >$100,000: 2019-2020: 18.4 (18.1-18.8), 2020-2021: 17.3 (16.8-17.7)). An association was observed between injury incidence ratio and log median high school household income in 2019-2020 [1.6 (1.1-2.5)] but not 2020-2021 [1.1 (0.8-1.6)] school years. Athletes from lower socioeconomic high schools reported increased injury incidence compared to higher socioeconomic high schools during the 2020-2021 academic school year. These results highlight the increased COVID-19 pandemic vulnerability in athletes from lower socioeconomic high schools. High school sport stakeholders should consider how abrupt sport stoppage can affect lower socioeconomic athletes. 2.

A prospective study on local cold injuries in northern Sweden

ABSTRACT The study aimed to determine the prevalence and incidence proportion of local cold injuries in northern Sweden, and identify associated factors. It was based on prospective data from surveys in 2015 and 2021 sent to a population-based sample in northern Sweden. Multiple binary logistic regression was performed. The study included 5,017 subjects (response rate 44.4%). The prevalence of cold injuries in the hands was 11.4%, feet 12.6%, and face 19.9%, while the incidence proportion was 1.0%, 1.0%, and 0.9%, respectively. Male gender was associated with incident cold injuries in the hands (OR 1.69; 95% CI 1.31–1.28), feet (OR 1.34; 95% CI 1.04–1.73), and face (OR 1.53; 95% CI 1.15–2.03); mental stress with cold injuries in the hands (OR 1.55; 95% CI 1.16–2.05) and feet (OR 1.39; 95% CI 1.04–1.88); previous stroke with cold injuries in the hands (OR 2.64; 95% CI 1.09–6.40) and face (OR 3.09; 95% CI 1.26–7.56); and Raynaud’s phenomenon with cold injuries in the hands (OR 2.48; 95% CI 1.80–3.41) and feet (OR 2.07; 95% CI 1.50–2.87). We conclude that male gender, mental stress, previous stroke, and Raynaud’s phenomenon increased the probability of contracting local cold injuries.

Uses of Health Care System Medical Care Services by Athletes After Injury at the HighSchool Level.

Health care utilization can vary by age group, geographic location, and socioeconomic status (SES). A paucity of information exists regarding the availability and utilization of medical care by injured scholastic athletes. The purpose of this study was to describe and compare injuries and health care service utilization by school SES over an academic year. Injury and health care service data was collected from 1 large school district. Percentage of free and reduced lunch (FRPL) for each school was calculated to stratify schools into high (<50% FRPL) and low (≥50.1% FRPL) SES groups. Incidence proportion and relative risk (RR) with 95% confidence intervals (95% CI) were calculated. About 1756 injuries were reported among over 7000 participating athletes from 14 high schools. Similar injury incidence proportions were reported between high and low SES schools (RR=1.10 [1.00-1.20]). Athletes from low SES schools were twice (RR=2.01 [1.21-3.35]) and over three (RR=3.42 [1.84-6.55]) times more likely to receive emergency and physical therapy care. SES was not associated with the use of physician, imaging, or surgery services. School medical providers and administrators should have ready and provide a list of trusted outside primary care and specialty providers that have experience in sports medicine. They should also enquire and follow up on which outside provider the high school athlete will seek care when referring out to outside providers. Injury incidence was similar between high and low SES schools. However, athletes from low SES high schools were over 2-fold more likely to use emergency department services. Understanding factors influencing health care services choice and usage by student athletes from different socioeconomic backgrounds may assist sport medicine clinicians in identifying barriers and potential solutions in improving time to health restoration, athlete outcomes, and health care monetary burden.

Profiling the injuries of law enforcement recruits during academy training: a retrospective cohort study

BackgroundInjuries within law enforcement are a significant issue as they increase organisational costs and workforce strain. As one of the biggest risk factors of future injury is previous injury, minimising injuries suffered during academy has multiple beneficial and long-term effects, including a healthier and fitter police force. The purpose of this study was to profile the injuries sustained at a law enforcement academy to inform future injury mitigation strategies.MethodsInjury data were provided retrospectively (from May 2012 to September 2019) from the official insurance records of a law enforcement academy and included nature, location, and activity performed at time of injury. A total of 4340 (3288 males, 938 females, 114 sex not stated) recruits participated in academy training during this period. Inclusion criteria for the data were (a) injury record related to a recruit, and (b) the recruit was injured during academy training., with injury defined as tissue damage caused by acute or repetitive trauma, inclusive of musculoskeletal, neural, and/or integumentary systems but excluding general medical conditions such as cardiac (e.g. heart attacks) or respiratory (asthma) that was subsequently reported for worker’s compensation. Injury incidence rates and proportions were calculated and a Spearman’s correlation analysis was conducted between injury rates over successive classes.ResultsAn injury incidence rate of 368.63 injuries per 1000 recruits per year was calculated in this population, with a moderate correlation coefficient (rs = 0.60) of increasing injury rates over chronologically occurring classes. Females also had higher injury rates than male recruits, even across various fitness levels. Trauma to joints and ligaments (49.30%) was the most common injury, and the knee the most common location (23.17%) of injury. Physical training (56.10%) was the most common activity being performed at the time of injury.ConclusionsThis research demonstrates a large number of lower limb, musculoskeletal injuries that often occur during physical training. Further research is needed to assess suitable injury mitigation programs.

The Impact of Statewide Limitations of Practice on High School Injury Incidence During the COVID-19 Season: An Ecological Study.

Abrupt training stoppage can increase injury incidence and risk following return to sport. The rate of coronavirus disease 2019 (COVID-19) infections in the general population has resulted in the abrupt stoppage of high school education and sport. The objective of this study was to (1) compare injury incidence proportion (IP) and excess injury in high school athletes before and during the COVID-19 pandemic; and (2) stratify by identified gender. The COVID-19 academic year will demonstrate increased injury incidence, and injury incidence will be similar between genders. Ecological. Level 2. High schools (6 states; 176 high schools) were matched between prepandemic and pandemic years. Injury IP with 95% confidence interval (CI) was calculated. Interrupted time series models with robust errors were performed to assess the IP ratio and excess injury incidence between prepandemic and pandemic academic calendar years. A total of 98,487 athletes participated in high school sport in the prepandemic year and 72,521 athletes in the pandemic year; 15,477 injuries were reported in the prepandemic year compared with 14,057 injuries during the pandemic year. Injury IP (CI) was 15.7 (15.5-15.9) and 19.4 (19.1-19.7) for the prepandemic and pandemic years, respectively. Injury incidence ratio increased by 1.3 (1.2-1.5) between the prepandemic and pandemic years. Excess injuries were 1812 greater in the pandemic year compared with the prepandemic year. Female and male athlete incidence ratios were similar. Prolonged sport stoppage due to the COVID-19 pandemic resulted in increased injury incidence compared with the previous high school academic year. High school sports stakeholders should consider longer periods of ramp up for training in lieu of future sport stoppages compared with usual preseason training. These data may also have more generalizable implications to other abrupt sport and physical activity stoppage scenarios such as earthquakes and hurricanes.

Epidemiologic characteristics of anterior cruciate ligament injury in 10 consecutive seasons of Turkish Division-1 professional football league

Objective: Anterior cruciate ligament (ACL) rupture is a potentially career-threatening injury in professional athletes. This study aimed to evaluate the epidemiology and injury characteristics of ACL rupture of male football players participating in the Turkish Super League. Materials and Methods: Epidemiologic characteristics of professional male football players participating in the professional first division Turkish Super League in 10 consecutive seasons were evaluated through a publicly available online soccer archive. Exposures in matches, as well as training, were calculated. Results: A total of 100 ACL injuries were included (mean age at the time of injury: 25.2±3.9). Of these, 13% were re-rupture and 11% were contralateral rupture. The ACL incidence rate was 0.4060 per 1000 hours of play during Super League matches, 0.0801 per 1000 hours of training (rate ratio [RR], 5.06; 95% CI, 3.25-11.84; p&lt;0.001), and 0.0622 per 1000 hours of total play. Although there was a regular number in other periods, the most frequent injury was in August. Also, training injuries peaked in July. A significantly higher incidence rate was found for the teams ranked from 1st to 5thplace compared with teams ranked 6th to 18th (0.0654 vs 0.0317 per 1000 hours of training; RR, 2.06; 95% CI, 1.44-3.65; p&lt;0.05). A similar finding was found for total injury incidence proportion (2.17% vs 1.36%; p&lt;0.05). Conclusion: Epidemiologic data is important as a resource for athletes and those responsible for their health to develop appropriate training and preparation programs to reduce the risk of ACL injury.

The Impact of COVID-19 Related Disruption on Injury Rates in Elite Men's Domestic Cricket.

This study aimed to investigate the impact of COVID-19 enforced prolonged training disruption and shortened competitive season, on in-season injury and illness rates. Injury incidence and percent proportion was calculated for the 2020 elite men's senior domestic cricket season and compared to a historical average from five previous regular seasons (2015 to 2019 inclusive). The injury profile for the shortened 2020 season was generally equivalent to what would be expected in a regular season, except for a significant increase in medical illness as a proportion of time loss (17% compared to historic average of 6%) and in-season days lost (9% compared to historic average of 3%) due to COVID-19 related instances (most notably precautionary isolation due to contact with a confirmed or suspected COVID-19 case). There was a significant increase in the proportion of in-season days lost to thigh injuries (24% compared to 9%) and a significant decrease in the proportion of days lost to hand (4% compared to 12%) and lumbar spine (7% compared to 21%) injuries. These findings enhance understanding of the impact prolonged period of training disruption and shortened season can have on cricket injuries and the challenges faced by practitioners under such circumstances.

Prevalence and incidence of injuries among female cricket players: a systematic review and meta-analysis.

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. 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. 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 were excluded if they did not have enough data to calculate prevalence or incidence, did not distinguish female injury data from male injury data, focused on athletes participating in other sports, or focused on case studies. 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 ScienceDirect were systematically searched from inception to August 2021. Additionally, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched. EBSCO MegaFile Premier, OpenGrey (SIGLE), WorldCat, Grey Matters, Grey Literature, and Google Scholar were searched for gray literature. Full-text articles that met the inclusion criteria were critically appraised using tools from JBI, and were extracted and synthesized in narrative summary and tabular format. Three meta-analyses were conducted: injury incidence rates, injury prevalence proportions, and injury incidence proportions. Heterogeneity was assessed using the I2 statistic and the random-effects model. Of the 7057 studies identified, 4256 were screened after duplicates were removed. A total of 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 proportion for community to elite cricket was 65.2% (SE 9.3, 95% CI 45.7-82.3) and the injury prevalence proportion for community cricket was 60% (SE 4.5, 95% CI 51.1-68.6). The injury incidence proportion 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. 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. PROSPERO CRD42020166052.

Overuse Injury, Substance Use, and Resilience in Collegiate Female Athlete.

BackgroundOveruse injury is a common stressor experienced by female collegiate athletes and is often underreported. In response, athletes may develop negative coping skills such as substance use. Alternatively, resilience is a modifiable trait that may positively influence response to musculoskeletal injuries and substance use.PurposeTo provide an updated epidemiological profile of overuse injury and substance use and examine the relationship between resilience, overuse injury, and substance use among collegiate female athletes.DesignCross-sectional studyMethodsTwo-hundred and thirty female collegiate athletes were classified into overuse injury and resilience groups. Overuse injury, pain, and substance use incidence proportions (IP) were calculated. Kruskal-Wallis analyses were performed to investigate differences in substance use among resilience groups. Analyses of covariance were performed to evaluate differences in overuse injuries, substantial overuse injuries, and time loss injuries, among resilience groups.ResultsIP for pain was 45.0% (95% CI: 38.2-51.9); Overuse injury 52.0% (45.1-58.9); Alcohol use 35.1% (28.6-41.6); Electronic cigarette use 19.5% (14.6-24.9); Cigarette use 2.8% (6-5.1); and Drug use 3.3% (0.9-5.8). No significant differences were found between resilience groups for the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC) variables (Pain: p=0.102; Overuse injury: p=0.331; Substantial overuse injury: p=0.084; Not playing: p=0.058), alcohol (p=0.723), or combined substance use (p=0.069).ConclusionsPain and overuse injury prevalence is high among female collegiate athletes. Alcohol followed by electronic cigarette use were the most commonly utilized substances. No significant differences were identified in substance use or overuse injury presentation between resilience groups, though further investigation is warranted.Level of Evidence3

Cross-validation of a machine learning algorithm that determines anterior cruciate ligament rehabilitation status and evaluation of its ability to predict future injury

ABSTRACT Classification algorithms determine the similarity of an observation to defined classes, e.g., injured or healthy athletes, and can highlight treatment targets or assess progress of a treatment. The primary aim was to cross-validate a previously developed classification algorithm using a different sample, while a secondary aim was to examine its ability to predict future ACL injuries. The examined outcome measure was ‘healthy-limb’ class membership probability, which was compared between a cohort of athletes without previous or future (No Injury) previous (PACL) and future ACL injury (FACL). The No Injury group had significantly higher probabilities than the PACL (p < 0.001; medium effect) and FACL group (p ≤ 0.045; small effect). The ability to predict group membership was poor for the PACL (area under curve [AUC]; 0.61<AUC<0.62) and FACL group (0.57<AUC<0.59). The ACL injury incidence proportion was highest in athletes with probabilities below 0.20 (9.4%; +2.7% to baseline), while athletes with probabilities above 0.80 had an incidence proportion of 4.1% (−2.6%). While findings that a low probability might represent an increase in injury risk on a group level, it is not sensitive enough for injury screening to predict a future injury on the individual level.

Frequency and Characteristics of Injuries and Rehabilitation Procedures in Rugby Players in Poland and France.

Objectives: Rugby is sport with a high risk of injury. Repeated changes in exercise intensity and the high training intensity may cause to overuse injuries and long-term disability. The aim of the study was to analyze the prevalence of injuries during trainings and forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Methods: The data was obtained from 60 professional rugby males from France and Poland. Data were collected using paper-based recording form. It was a specially designed questionnaire which concerned specific details of the injury, including body location, type of injury, treatment and number of days off lost from playing rugby and on forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Results: During the study period, the overall incidence rate for injury suggested a 1.04 times more often injury occurrence (IRR = 1.04, 95% CI: 0.08; 2.00) among Polish players compared with French players; however, the distribution of injuries varied by country. The training injury incidence (TII) and incidence proportion (IP) were also higher in Poland than in France (p < 0.05) with the sprain as the most frequent type of injury in all rugby players. France was 7.8 times (IRR = 7.88, 95% CI: 1.29; 3.21) more likely to sustain a fracture than Poland, which much often experienced less serious injuries (bruise, rapture of muscle and ligament) (IRR = 3.02, 95% CI: 2.06; 3.98). Polish players were provided with various forms of physiotherapy while Franch players often worked with a physiotherapist with a therapeutic method (p < 0.005). Poland and France reported experiencing side effects after an injury and the most frequent was pain. In their opinions, the reasons influencing the effectiveness of rehabilitation are too quick return to the game and too short time of rehabilitation. Conclusions: The competitive level of the rugby player influences not only the frequency and type of injury occurrence, but also access to the different forms of rehabilitation. Nonetheless, the side effects occurring after injury and the causes of ineffective rehabilitation are still similar. Further studies are needed to gather significant data to accurately formulate future injury prevention protocols or recommend modifications to game laws or competition formats, aiming at players’ welfare.

Generalized Joint Hypermobility and Injuries: A Prospective Cohort Study of 185 Pre-Professional Contemporary Dancers.

Generalized joint hypermobility (GJH) has been mentioned as one of the factors associated with dance injuries, but the findings are inconclusive. This study aims to investigate whether GJH, based on different Beighton score cut-off points, is a potential risk factor for injuries in pre-professional dancers. Four cohorts of first-year pre-professional dancers (N = 185), mean age 19.1 ± 1.3 years, were screened on musculoskeletal functioning at the start of their academic year. The Beighton score was used to measure GJH. During the academic year, the dancers completed monthly questionnaires about their physical and mental health. Based on the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC), three injury definitions were used (i.e., all complaints, substantial injury, and time-loss injury). To examine potential risk factors for injuries, univariate and multivariate regression models were applied. The response rate of monthly completed questionnaires was 90%. The overall mean (SD) Beighton score was 2.8. The 1-year injury incidence proportion was 67.6% (n = 125), 43.2% (n = 80), and 54.6% (n = 101) for all complaint injuries, substantial injuries, and time-loss injuries, respectively. The multivariate analyses showed a significant association between a previous long lasting injury in the past year and the three injury definitions (p < 0.05). Pre-professional contemporary dancers are at high risk for injuries and hypermobility. However, these two variables are not associated with each other. Health professionals should take injury history into account when assessing dance students, because this variable is associated with increased injury risk.

The relationship between flourishing, injury status, and resilience in collegiate athletes

Background Flourishing is a multi-dimensional construct that encompasses physical, psychological and social well-being. A proposed positive attribute of flourishing is resilience, which is the ability to bounce back despite the presence of stressors. A common stressor among athletes is overuse injuries, which may negatively affect well-being. Objective To examine the relationships of resilience and overuse injury with flourishing in collegiate athletes. Materials and methods 253 college athletes participated. The Flourishing Scale, Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC), and Brief Resilience Scale (BRS) were administered via online questionnaire. For OSTRC scores, athletes were classified into injury and participation status groups. For BRS scores, athletes were classified into low resilience (LR), normal resilience (NR), and high resilience (HR) groups. Results Median flourishing score was 50.0 (46.5–53.5); mean BRS score was 21.6 (SD 4.3). Overuse injury and substantial overuse injury incidence proportion (IP) were 25.4 (95% CI: 20.3, 30.5) and 9.1 (95% CI: 7.0, 11.2). The IP for participants unable to play was 15.1 (95% CI: 12.9, 17.2). Significant differences were found in flourishing among resilience groups (p = 0.002) but not among overuse injury groups (p = 0.140) or participation variables (p = 0.205). Conclusion College athletes demonstrated high flourishing scores. Flourishing demonstrated a significant relationship with resilience across all groups but not among overuse injury or participation status. This finding indicates that college athlete well-being is strongly associated with resilience. Future longitudinal studies are needed to determine if resilience can be modified to positively influence athlete well-being.

Injury Profile in Women's Football: A Systematic Review and Meta-Analysis.

Football is the most popular sport among women; however, little is known about the injury profile in this population. This information would help design tailored injury risk mitigation strategies that may make football safer for women. The aim of this study was to perform a systematic review and meta-analysis of epidemiological data of injuries in women´s football. A systematic review following PRISMA guidelines was performed up to January 2020 in PubMed, Web of Science, Sportdiscus and the Cochrane Library databases. Twenty-two studies reporting the incidence of injuries in women football were analysed. Two reviewers independently extracted data (intraclass correlation coefficient [ICC] for inter-reviewer reliability = 0.87) and assessed study quality using the STROBE statement, GRADE approach, Newcastle Ottawa Scale and Downs and Black assessment tools. Studies were combined in pooled analyses (injury incidence and injury proportion) using a Poisson random effects regression model. The overall incidence of injuries in female football players was 6.1 injuries/1000h of exposure. Match injury incidence (19.2 injuries/1000h of exposure) was almost six times higher than training injury incidence rate (3.5 injuries/1000h of exposure). Lower extremity injuries had the highest incidence rates (4.8 injuries/1000h of exposure). The most common types of injuries were muscle/tendon (1.8 injuries/1000h of exposure) and joint (non-bone) and ligament (1.5 injuries/1000h of exposure), which were frequently associated with traumatic incidents. Slight/minimal injuries (1-3days of time loss) were the most common. The incidence rate of injuries during matches in the top five world ranking leagues was higher than the rest of the leagues (19.3 vs 10.7 injuries/1000h of exposure, respectively). The weighted injury proportion was 1.1 (95% confidence interval = 0.6-1.7) whereby on average players sustained more than one injury per season. Female football players are exposed to a substantial risk of sustaining injuries, especially during matches that require the highest level of performance. To markedly reduce overall injury burden, efforts should focus on introducing and evaluating preventative measures that target match specific dynamics to make football players more capable of responding to the challenges that they have to deal with during match play. This systematic review was registered in the PROSPERO international prospective register of systematic reviews (ID = CRD42019118152).
