A Prospective Study

This prospective cohort study aimed to identify the incidence and characteristics of Taekwondo-related injuries according to age, sex, and event type (i.e., practice or competition) based on a web-based injury surveillance system (ISS) with a follow-up period of 12 months. A total of 285 members of the Korea Taekwondo Association who competed in the 2016 season participated. Injury incidence rates (IRs) were calculated per 1000 athlete-exposures (AEs). Injury rate ratios (RRs) with 95% confidence intervals were calculated and compared regarding age, sex, and event type. During the season, 336 injuries were reported, resulting in a rate of 6.31/1000 AEs. The most common location, type, and mechanism of injury in Taekwondo athletes were the foot/ankle, ligament sprain, and contact with another player, respectively. The overall injury IRs associated with Taekwondo practicing and competition were 4.79/1000 AEs and 24.86/1000 AEs, respectively. The overall injury RR related to both practice and competition was higher in youth athletes than in adult athletes. However, adult athletes were more likely to sustain more severe injuries. Korean elite Taekwondo athletes were commonly exposed to injury, especially youth and female athletes. Therefore, continuation of the ISS suggests the development of interventions for preventing injuries sustained by Taekwondo athletes.

Background: There is limited epidemiologic data on pediatric basketball injuries and the correlation of these injuries with sex-based differences pre- and post-adolescence. Purpose: To describe sex and age-based injury rates associated with common pediatric basketball injuries. Methods: A descriptive epidemiology study was conducted utilizing publicly available injury data from the National Electronic Injury Surveillance System (NEISS) and participation data from the National Sporting Goods Association (NSGA). Data on pediatric basketball injuries from January 2012 – December 2018 in patients ages 7-17 years were extracted and used to calculate national injury incidence rates with 95% confidence intervals. Results: Over 7 years, 9,582 basketball injuries were reported annually in the NEISS in pediatric patients 7-17 years old, which corresponds to an annual national estimate of 294,920 visits. The 5 most common diagnoses were ankle strain/sprain (17.7%), finger strain/sprain and finger fracture (12.1%), concussion/head injury (9.4%), knee strain/sprain (4.5%), and facial laceration (3.3%). There was a notable increase in injury rate in adolescents when compared with childhood ages; 7- to 11-year-old category accounted for 19.1% of estimated injuries (56,242 injuries per year) and the 12- to 17-year-old category accounted for 80.9% (238,678 injuries per year). While boys accounted for the majority of injuries in both age groups [72.6% of all injuries (40,824 injuries per year) in the 7- to 11-year-old category and 74.4% of all injuries (177,572 injuries per year) in the 12- to 17-year-old category], overall, there was no significant difference in injury rate between boys and girls (boys: 91 injuries per 100,000 athlete days, 95% CI = 73-109; girls: 110 injuries per 100,000 athlete days, 95% CI = 92-128; p=0.140). Overall injury rates across the two age groups are reported in Table 1. Head injuries/concussions were a frequent cause of presentation (second only to finger injuries) in 7- to 11-year-olds, and occurred at a similar rate in girls and boys. In adolescents, ankle injuries were the most common injury overall, but there was a most notable increase in the rate of girls’ head and knee injury compared with their boy counterparts within these ages (Table 1). Conclusions: Ankle injuries continue to be the most predominant pediatric basketball injury. However, disproportionate rates of girls’ head and knee injuries during adolescent basketball suggest that style of play and knee injury prevention programs should target girls participating in youth basketball.

Context Women's softball athletes account for approximately 9% of all female athletes competing within the National Collegiate Athletic Association (NCAA). Background Routine surveillance of NCAA women's softball injuries is important for identifying the emerging injury patterns in this sport. Methods Exposure and injury data collected during competitive seasons in the NCAA Injury Surveillance Program during 2014–2015 through 2018–2019 (5 years) academic years were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics; injury rate ratios (IRRs) were used to examine differential injury rates. Results The overall injury rate was 3.92 per 1000 athlete exposures. Practice and preseason injury rates increased during 2015/16 through 2018/19. Most injuries were shoulder (15.2%), hand/wrist (11.8%), knee (11.2%), and head/face injuries (11.2%) and were classified as contusions (14.2%), sprains (14.1%), and inflammatory conditions (14.1%). Concussion (6.8%) was the most commonly reported injury, and concussion incidence fluctuated during 2014–2015 through 2018–2019. Summary Results indicate an increasing trend in practice and preseason injury incidence. Findings also suggest that workload accumulation in the shoulder and the mechanisms of concussion warrant further attention in this population.

Abstract Purpose The purpose of this study was to provide updated high school soccer concussion incidence rates by gender and event type. It was hypothesized more soccer injuries occur in females, during games, and that females would have higher injury rates and risk. Methods This study used data from the Rank One Health Injury Surveillance Database (ROH ISD) between 2012–17, from 1,999 high schools in student-athletes ages 14 to 18. This study examined high school soccer concussion incidence rate reporting by Athletic Trainers (ATCs). Injury rates per 1,000 Athletic Exposures, injury rate ratios (IRRs), and risk ratios (RR) were calculated by event type. All 95% confidence intervals (CIs) not containing 1.0 were considered statistically significant. Results A total of 6,669 concussions with an average age of 15.62 (SD=1.26) were reported by ATCs in high school soccer from 2012-17. More concussions occurred in games (4,527; 67.9%) than practices (2,142; 32.1%). During games, males (3.49/1,000 AEs) had lower rates than females (7.78/1,000 AEs). During practice, males (0.52/1,000 AEs) had lower rates than females (0/97/1,000 AEs). Injury risk ratio was higher in games than practices for males (RR=6.71; 95% CI=6.67, 6.75) and females (RR=8.11; 95% CI=8.08, 8.14). Conclusion This study marks the largest epidemiological high school soccer concussion incidence investigation to date. The findings from this study provide updated high school soccer concussion incidence rates and provide further evidence of differences in injury rates when comparing practices and games.

A Prospective Study

Background: Judo is a full-contact fighting sport that may lead to severe injuries. There are limited data available on the incidence of judo-related injuries. The French Judo Federation has established a surveillance system to document the frequency and type of injuries during judo competitions. Purpose: To describe the incidence rates and types of judo-related traumatic injuries during 21 seasons of competitions in France with respect to athlete (judoka) age, sex, and level of performance. Study Design: Descriptive epidemiology study. Methods: Between 1993 and 2014, each physician in charge of each judo competition filled out a form in which he/she documented the number of competing judokas, the number of fights, the number of medical interventions, the specific type of traumatic injuries for each intervention, the number of fight interruptions, and the number of athletes removed from the competition venue because of an injury. The age, sex, and level of performance of each judoka were also documented. Variance analysis was applied to assess whether differences in incidence rates of injuries between groups were significant (Student t test and chi-square test). Results: Surveillance of 421,670 fights demonstrated 3511 injuries in 316,203 judokas (incidence proportion, 1.1%). Among the injuries recorded, the most common were sprains (54.3%), fractures (15.6%), and dislocations (12.5%). Female athletes exhibited significantly higher incidence rates for knee sprains and elbow dislocations, whereas male athletes exhibited a higher incidence rate for shoulder dislocations ( P < .001 for all). Regarding age, higher incidence rates were observed in young adults (aged 18-20 years) for acromioclavicular sprains and in children (aged 10-14 years) for clavicle fractures compared with adults (aged 21-35 years) ( P < .001 for both). Both young adult and adult athletes had a higher incidence rate of shoulder dislocations ( P < .001). Regarding the level of performance, athletes competing at higher levels had a higher incidence rate of sprains to the knee ( P < .001). Conclusion: During 21 years of surveillance of injuries in judo competitions in France, the incidence proportion of injuries was 1.1%. Significant differences in incidence rates demonstrated when considering age, sex, and level of performance may help in developing strategies to prevent traumatic injuries in the future.

Background: Prospective studies on injuries in martial arts competitions are scarce, especially those involving time-loss injuries. The upsurge of karate athletes competing in top-level karate competitions warrants elucidation of the time-loss injury risk. Purpose: To determine the time-loss injury proportion and incidence rate, describe the injury pattern among elite senior karate athletes, and compare the risk of time-loss injuries in male versus female athletes and in individual (ie, weight categories) versus team competitions (free-weight category). Study Design: Descriptive epidemiology study. Methods: Data were collected at 4 consecutive World Karate Championships (2010, 2012, 2014, and 2016). Injury incidence rates were calculated per 1000 athlete-exposures (IIRAE) and per 1000 minutes of exposure (IIRME), with 95% CIs. Subgroups were compared by calculating their rate ratios with 95% CIs. Results: A total of 506 injuries were recorded, of which 51 were time-loss injuries (10%). The overall time-loss injury rate was significantly lower for female versus male athletes and slightly lower for team versus individual competitions. Overall, 1.4% of all athletes sustained a time-loss injury, and the IIRAE and IIRME were 5.13 (95% CI, 3.82-6.74) and 1.98 (95% CI, 1.47-2.60), respectively. The most common type of time-loss injury was fracture (41%), followed by dislocation (20%) and concussion (12%). Conclusion: The time-loss injury incidence rate for top-level karate competitions found in this prospective study was relatively low. Comprehensive knowledge about the incidence of time-loss injuries during karate competitions represents an essential basis to develop effective strategies for injury prevention. Thus, the introduction of a uniform injury surveillance system in martial arts is of utmost importance.

Context: Whereas researchers have provided estimates for the number of head impacts sustained within a youth football season, less is known about the number of plays across which such impact exposure occurs.Objective: To estimate the number of plays in which youth football players participated during the 2013 season and to estimate injury incidence through play-based injury rates.Design: Descriptive epidemiology study.Setting: Youth football.Patients or Other Participants: Youth football players (N = 2098; age range, 5−15 years) from 105 teams in 12 recreational leagues across 6 states.Main Outcome Measure(s): We calculated the average number of athlete-plays per season and per game using independent-samples t tests to compare age groups (5–10 years old versus 11–15 years old) and squad sizes (&lt;20 versus ≥20 players); game injury rates per 1000 athlete-exposures (AEs) and per 10 000 athlete-plays; and injury rate ratios (IRRs) with 95% confidence intervals (CIs) to compare age groups.Results: On average, youth football players participated in 333.9 ± 178.5 plays per season and 43.9 ± 24.0 plays per game. Age groups (5- to 10-year-olds versus 11- to 15-year-olds) did not differ in the average number of plays per season (335.8 versus 332.3, respectively; t2086.4 = 0.45, P = .65) or per game (44.1 versus 43.7, respectively; t2092.3 = 0.38, P = .71). However, players from smaller teams participated in more plays per season (373.7 versus 308.0; t1611.4 = 8.15, P &lt; .001) and per game (47.7 versus 41.4; t1523.5 = 5.67, P &lt; .001). Older players had a greater game injury rate than younger players when injury rates were calculated per 1000 AEs (23.03 versus 17.86/1000 AEs; IRR = 1.29; 95% CI = 1.04, 1.60) or per 10 000 athlete-plays (5.30 versus 4.18/10 000 athlete-plays; IRR = 1.27; 95% CI = 1.02, 1.57).Conclusions: A larger squad size was associated with a lower average number of plays per season and per game. Increasing youth football squad sizes may help reduce head-impact exposure for individual players. The AE-based injury rates yielded effect estimates similar to those of play-based injury rates.

Objectives: This study aimed to assess how menstrual cycle phase and extended menstrual cycle length influence the incidence of injuries in international footballers.Methods: Over a 4-year period, injuries from England international footballers at training camps or matches were recorded, alongside self-reported information on menstrual cycle characteristics at the point of injury. Injuries in eumenorrheic players were categorized into early follicular, late follicular, or luteal phase. Frequencies were also compared between injuries recorded during the typical cycle and those that occurred after the cycle would be expected to have finished. Injury incidence rates (per 1,000 person days) and injury incidence rate ratios were calculated for each phase for all injuries and injuries stratified by type.Results: One hundred fifty-six injuries from 113 players were eligible for analysis. Injury incidence rates per 1,000 person-days were 31.9 in the follicular, 46.8 in the late follicular, and 35.4 in the luteal phase, resulting in injury incidence rate ratios of 1.47 (Late follicular:Follicular), 1.11 (Luteal:Follicular), and 0.76 (Luteal:Late follicular). Injury incident rate ratios showed that muscle and tendon injury rates were 88% greater in the late follicular phase compared to the follicular phase, with muscle rupture/tear/strain/cramps and tendon injuries/ruptures occurring over twice as often during the late follicular phase compared to other phases 20% of injuries were reported as occurring when athletes were “overdue” menses.Conclusion: Muscle and tendon injuries occurred almost twice as often in the late follicular phase compared to the early follicular or luteal phase. Injury risk may be elevated in typically eumenorrheic women in the days after their next menstruation was expected to start.

Context Injuries in professional ultimate Frisbee (ultimate) athletes have never been described. Objective To determine injury rates, profiles, and associated factors using the first injury-surveillance program for professional ultimate. Design Descriptive epidemiology study. Setting American Ultimate Disc League professional ultimate teams during the 2017 season. Patients or Other Participants Sixteen all-male teams. Main Outcome Measure(s) Injury incidence rates (IRs) were calculated as injuries per 1000 athlete-exposures (AEs). Incidence rate ratios were determined to compare IRs with 95% confidence intervals, which were used to calculate differences. Results We observed 299 injuries over 8963 AEs for a total IR of 33.36 per 1000 AEs. Most injuries affected the lower extremity (72%). The most common injuries were thigh-muscle strains (12.7%) and ankle-ligament sprains (11.4%). Running was the most frequent injury mechanism (32%). Twenty-nine percent of injuries involved collisions; however, the concussion rate was low (IR = 0.22 per 1000 AEs). Injuries were more likely to occur during competition and in the second half of games. An artificial turf playing surface did not affect overall injury rates (Mantel-Haenszel incidence rate ratio = 1.28; 95% confidence interval = 0.99, 1.67). Conclusions To our knowledge, this is the first epidemiologic study of professional ultimate injuries. Injury rates were comparable with those of similar collegiate- and professional-level sports.

Background: Although data exist on injuries in youth football leagues, there are limited recent data on injury incidence in middle school football. Updated injury incidence estimates can help drive the development of injury prevention strategies. Purpose: Describe the epidemiology of injuries in middle school football during school years 2015-2016 to 2017-2018. Study Design: Descriptive epidemiology study. Methods: Data originated from 9 public middle schools in Virginia during school years 2015-2016 to 2017-2018. Certified athletic trainers collected injury and athlete-exposure (AE) data from school-sanctioned games and practices in boys’, football. Injury counts and rates per 1000 AEs were calculated. Injury rate ratios with 95% CIs compared rates between games and practices. Results: Overall, 664 middle school boys’, football injuries were reported, leading to an overall injury rate of 20.54 per 1000 AEs (95% CI, 18.98-22.11). The time loss injury rate (inclusive of injuries with participation restriction time ≥24 hours) was 9.28 per 1000 AEs (95% CI, 8.23-10.33). The injury rate was higher in competition than practice (36.19 vs 17.97 per 1000 AEs; injury rate ratio, 2.01; 95% CI, 1.69-2.40). Most injuries were to the head/face (competition, 20.6%; practice, 15.8%) and hand/wrist (competition, 18.8%; practice, 16.4%) and were diagnosed as contusions (competition, 30.9%; practice, 25.9%) and sprains (competition, 19.4%; practice, 12.6%). Competitions also had a large proportion of concussions (10.3%). Overall, 80.0% and 66.9% of injuries were due to contact in competition and practice, respectively; of these contact-related injuries, 62.1% and 41.6% were specifically player contact. Conclusion: Injury distributions parallel those found in previous research from middle school and other sport settings. Injury rates in middle school football were higher than those reported in previous findings in high school and college. However, caution must be taken when interpreting findings in relation to other surveillance systems with varying methodologies. Still, the findings highlight the need for injury prevention strategies within middle school football, particularly as related to contact-related mechanisms.

Context Football is among the most popular collegiate sports in the United States, and participation in National Collegiate Athletic Association (NCAA) football has risen in recent years. Background Continued monitoring of football injuries is important for capturing the evolving burden of injuries in NCAA football. The purpose of this study was to describe the epidemiology of football-related injuries among men's NCAA football players during the 2014–2015 through 2018–2019 academic years. Methods Exposure and injury data collected in the NCAA Injury Surveillance Program were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics, and injury rate ratios were used to examine differential injury rates. Results The overall injury rate was 9.31 per 1000 athlete-exposures. Most injuries occurred during general play (17.5%), blocking (15.8%), and tackling (14.0%). Concussions (7.5%), lateral ligament complex tears (6.9%), and hamstring tears (4.7%) were the most commonly reported injuries. Conclusions Results of this study were generally consistent with previous findings, though changes over time in rates of commonly reported injuries warrant attention. Continued monitoring of injury incidence is needed to appraise the effectiveness of recently implemented rules changes.
