The NTL injuries accounted for a substantial amount of the total number of injuries sustained by high school student-athletes. This project demonstrates the feasibility of creating large-scale injury surveillance systems using commercially available injury-tracking software.
IMPORTANCE A report by the Institute of Medicine called for comprehensive nationwide concussion incidence data across the spectrum of athletes aged 5 to 23 years. OBJECTIVE To describe the incidence of concussion in athletes participating in youth, high school, and collegiate American football.
Background/Aim Recent injury data for collegiate-level swimming and diving is limited. Previous data is limited to single seasons, elite and national team athletes, or emergency department data. This study describes the epidemiology of men’s and women’s swimming and diving injuries reported by the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) during the 2009/10-2013/14 academic years. Methods Injuries and athlete-exposure (AE) data reported within nine men’s and 13 women’s swimming and diving programs were analyzed. Injury rates, injury rate ratios (IRR), and injury proportions by body site, diagnosis, and mechanism were reported with 95% confidence intervals (CI). Results The ISP captured 149 and 208 injuries for men’s and women’s swimming and diving, respectively, leading to injury rates of 1.54/1000AEs and 1.71/1000AEs. Among females, divers had a higher injury rate (2.49/1000AEs) than swimmers (1.63/1000AEs; IRR=1.53; 95%CI: 1.07, 2.19). Injury rates for male divers (1.94/1000AEs) and swimmers (1.48/1000AEs) did not differ (IRR=1.33; 95%CI: 0.85, 2.31). Most injuries occurred to the shoulder and resulted in strains. Many injuries were classified as overuse or non-contact. Female swimmers had a higher overuse injury rate (1.04/1000AEs) than male swimmers (0.66/1000AEs; IRR=1.58; 95%CI: 1.14, 2.19). Overuse injury rates for female divers (0.54/1000AEs) and male divers (0.46/1000AEs) did not differ (IRR=1.16; 95%CI: 0.40, 3.34). Conclusions Shoulder, strain, and overuse injuries were common in collegiate men’s and women’s swimming and diving. In addition, divers may have higher injury rates than swimmers, although small reported numbers in this study warrant additional research.
Background:Research evaluating the effect of comprehensive coach education and practice contact restriction in youth football injury rates is sparse. In 2012, USA Football released their Heads Up Football coaching education program (HUF), and Pop Warner Football (PW) instituted guidelines to restrict contact during practice.Purpose:To compare injury rates among youth football players aged 5 to 15 years by whether their leagues implemented HUF and/or were PW-affiliated.Study Design:Cohort study; Level of evidence, 2.Methods:Athletic trainers (ATs) evaluated and tracked injuries at each practice and game during the 2014 youth football season. Players were drawn from 10 leagues across 4 states. The non–Heads Up Football (NHUF) group consisted of 704 players (none of whom were PW-affiliated) from 29 teams within 4 leagues. The HUF+PW group consisted of 741 players from 27 teams within 2 leagues. The HUF-only group consisted of 663 players from 44 teams within 4 leagues. Injury rates and injury rate ratios (IRRs) were reported with 95% CIs.Results:A total of 370 injuries were reported during 71,262 athlete-exposures (AEs) (rate, 5.19/1000 AEs). Compared with the NHUF group (7.32/1000 AEs), the practice injury rates were lower for the HUF+PW group (0.97/1000 AEs; IRR, 0.13; 95% CI, 0.08-0.21) and the HUF-only group (2.73/1000 AEs; IRR, 0.37; 95% CI, 0.26-0.53). Compared with the NHUF group (13.42/1000 AEs), the game injury rate was lower for the HUF+PW group (3.42/1000 AEs; IRR, 0.25; 95% CI, 0.15-0.44) but not for the HUF-only group (13.76/1000 AEs; IRR, 1.02; 95% CI, 0.73-1.43). Also, the HUF+PW game injury rate was lower than that of HUF-only (IRR, 0.20; 95% CI, 0.12-0.36). Higher injury rates were typically found in those aged 11 to 15 years compared with those aged 5 to 10 years. However, stronger effects related to HUF implementation and PW affiliation were seen among 11- to 15-year-olds. When restricted to concussions only, the sole difference was found between the practice concussion rates among 11- to 15-year-olds in the HUF+PW (0.14/1000 AEs) and NHUF groups (0.79/1000 AEs) (IRR, 0.18; 95% CI, 0.04-0.85).Conclusion:These findings support comprehensive coach education and practice contact restrictions as effective methods of injury mitigation. Future research should continue evaluating similar programming within other levels of competition and sports.
Context Recent injury-surveillance data for collegiate-level women's gymnastics are limited. In addition, researchers have not captured non–time-loss injuries (ie, injuries resulting in restriction of participation <1 day). Objective To describe the epidemiology of National Collegiate Athletic Association (NCAA) women's gymnastics injuries during the 2009–2010 through 2013–2014 academic years. Design Descriptive epidemiology study. Setting Aggregate injury and exposure data collected from 11 women's gymnastics programs providing 28 seasons of data. Patients or Other Participants Collegiate student-athletes participating in women's gymnastics during the 2009–2010 through 2013–2014 academic years. Intervention(s) Women's gymnastics data from the NCAA Injury Surveillance Program (ISP) during the 2009–2010 through 2013–2014 academic years were analyzed. Main Outcome Measure(s) Injury rates; injury rate ratios; injury proportions by body site, diagnosis, and apparatus; and injury proportion ratios were reported with 95% confidence intervals (CIs). Results The ISP captured 418 women's gymnastics injuries, a rate of 9.22/1000 athlete-exposures (AEs; 95% CI = 8.33, 10.10). The competition injury rate (14.49/1000 AEs) was 1.67 times the practice injury rate (8.69/1000 AEs; 95% CI = 1.27, 2.19). When considering time-loss injuries only, the injury rate during this study period (3.62/1000 AEs) was lower than rates reported in earlier NCAA ISP surveillance data. Commonly injured body sites were the ankle (17.9%, n = 75), lower leg/Achilles tendon (13.6%, n = 57), trunk (13.4%, n = 56), and foot (12.4%, n = 52). Common diagnoses were ligament sprain (20.3%, n = 85) and muscle/tendon strain (18.7%, n = 78). Overall, 12.4% (n = 52) of injuries resulted in time loss of more than 3 weeks. Of the 291 injuries reported while a student-athlete used an apparatus (69.6%), most occurred during the floor exercise (41.9%, n = 122) and on the uneven bars (28.2%, n = 82). Conclusions We observed a lower time-loss injury rate for women's gymnastics than shown in earlier NCAA ISP surveillance data. Safety initiatives in women's gymnastics, such as “sting mats,” padded equipment, and a redesigned vault table, may have contributed to minimizing the frequency and severity of injury.
