Context Frequent inspection of sports-related injury epidemiology among National Collegiate Athletic Association (NCAA) women's basketball student-athletes is valuable for identifying injury-related patterns. Background Emerging patterns in epidemiology of NCAA women's basketball injuries are unknown though general sports medicine practices, and playing rules and regulations have evolved in recent years. Methods Athlete exposures (AEs) and injury incidence data were reported to the NCAA Injury Surveillance Program between 2014–2015 and 2018–2019. Injury counts, rates, and proportions were used to examine injury characteristics, and injury rate ratios (IRRs) were used to assess injury rate differences. Results Practice and competition injury rates were 5.93 and 10.35 per 1000 AEs, respectively. Preseason injury rates were higher than regular (IRR = 1.41; 95% CI = 1.31, 1.53) and postseason (IRR = 3.12; 95% CI = 2.39, 4.07). Ankle sprains (14.3%), concussions (7.5%), and anterior cruciate ligament tears (2.5%) were the most commonly reported injuries. Summary Higher rates of practice and competition injuries, as well as ankle sprains, were observed relative to previous reports; continuous monitoring is necessary to identify potential contributing factors to these trends.

Context The National Collegiate Athletic Association held the first women's soccer championship in 1982; sponsorship and participation have greatly increased since. Background Routine examinations of athlete injuries are important for identifying emerging temporal patterns. Methods Exposure and injury data collected in the National Collegiate Athletic Association Injury Surveillance Program during the 2014–2015 through 2018–2019 seasons 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 8.33 per 1000 athlete-exposures. Lateral ligament complex tears (ankle sprains) (8.6%), concussions (8.3%), and quadriceps tears (5.0%) were the most commonly reported injuries. Rates of lateral ligament complex tears followed an increasing trajectory during the study period, whereas quadriceps tear rates fluctuated during the early years, and concussion rates decreased then increased. Summary The findings of this study were mostly consistent with existing evidence; notable temporal patterns were observed with regard to lateral ligament complex tears and concussions.

Background: Updated epidemiology studies examining sports-related concussions (SRCs) are critical in evaluating recent efforts aimed at reducing the incidence of SRCs in National Collegiate Athletic Association (NCAA) sports. Purpose: To describe the epidemiology of SRCs in 23 NCAA sports during the 2014/15-2018/19 academic years. Study Design: Descriptive epidemiology study. Methods: SRC and exposure data collected in the NCAA Injury Surveillance Program were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics by sport, event type (practices, competitions), injury mechanism (player contact, surface contact, equipment/apparatus contact), and injury history (new, recurrent). Injury rate ratios (IRRs) were used to examine differential injury rates, and injury proportion ratios (IPRs) were used to examine differential distributions. Results: A total of 3497 SRCs from 8,474,400 athlete-exposures (AEs) were reported during the study period (4.13 per 10,000 AEs); the competition-related SRC rate was higher than was the practice-related SRC rate (IRR, 4.12; 95% CI, 3.86-4.41). The highest SRC rates were observed in men’s ice hockey (7.35 per 10,000 AEs) and women’s soccer (7.15 per 10,000 AEs); rates in women’s soccer and volleyball increased during 2015/16-2018/19. Player contact was the most prevalently reported mechanism in men’s sports (77.0%), whereas equipment/apparatus contact was the most prevalently reported mechanism in women’s sports (39.2%). Sex-related differences were observed in soccer, basketball, softball/baseball, and swimming and diving. Most SRCs reported in men’s sports (84.3%) and women’s sports (81.1%) were reported as new injuries. Conclusion: Given the increasing SRC rates observed in women’s soccer and volleyball during the latter years of the study, these results indicate the need to direct further attention toward trajectories of SRC incidence in these sports. The prevalence of equipment/apparatus contact SRCs in women’s sports also suggests that SRC mechanisms in women’s sports warrant further investigation. As most SRCs during the study period were reported as new injuries, the prevalence of recurrent SRCs in men’s and women’s ice hockey is also noteworthy.

Churilla, JR, Summerlin, M, Richardson, MR, and Boltz, AJ. Mean combined relative grip strength and metabolic syndrome: 2011–2014 National Health and Nutrition Examination Survey. J Strength Cond Res 34(4): 995–1000, 2020—The purpose of this study was to examine the relationships among mean combined relative grip strength (MCRGS), the metabolic syndrome (MetS), and the individual MetS criterion using a nationally representative sample of U.S. adults (≥20 years of age). The study sample included subjects from the 2011–2014 National Health and Nutrition Examination Study (NHANES). Subject MCRGS, using an average of 3 attempts per hand, was measured by a trained examiner using a handgrip dynamometer. All anthropometric, blood pressure, and serum blood measures used to diagnose the MetS were obtained in a Mobile Examination Center using a subsample of NHANES subjects (N = 4,664). Results suggest a favorable inverse dose–response relationship exists across quartiles of increased MCRGS and likelihood of MetS in both men and women (p < 0.0001 for trend). In analyses adjusted for age, race, education, and meeting aerobic physical activity recommendations, when compared with a referent group in the lowest quartile of MCRGS (MCRGS <2.66 kg/body mass index [BMI] in men; MCRGS <1.58 kg/BMI in women), those in the third (MCRGS >3.20–3.77 kg/BMI in men; MCRGS >1.99–2.38 kg/BMI in women) and fourth quartile (MCRGS >3.77 kg/BMI in men; MCRGS >2.38 kg/BMI in women), were significantly less likely to have the MetS, independent of gender (p ≤ 0.05 for all). Similar findings varied according to individual MetS criterion. These findings provide the first data suggesting that increased MCRGS may be inversely related to the MetS or the individual MetS criterion in a nationally representative sample of U.S. adults.

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.
