Preseason Functional Performance Test Measures Are Associated With Injury in Female College Volleyball Players.

CONTEXT: Preseason functional performance test measures have been associated with noncontact time-loss injury in some athletic populations. However, findings have been equivocal with many studies consisting of heterogeneous populations. OBJECTIVE: To determine if preseason standing long jump and/or single-leg hop test scores are associated with a noncontact time-loss injury to the lower quadrant (LQ = low back or lower-extremities) in female Division III college volleyball (VB) players. DESIGN: Prospective cohort study. SETTING: National Collegiate Athletic Association Division III female VB teams. PATIENTS: A total of 82 female college VB players (age = 18.9 [1.0] y). MAIN OUTCOME MEASURES: Standing long jump and single-leg hop test measures were collected at the start of the official preseason. Athletic trainers tracked all time-loss injuries and their mechanisms. Athletes were categorized as at risk if their preseason standing long jump <80% height, bilateral single-leg hop <70% height, and had a SLH side-to-side asymmetry >10%. RESULTS: The noncontact time-loss overall injury rate for the LQ region in at-risk athletes was 13.5 (95% confidence interval [CI], 4.3-31.5) per 1000 athletic exposures. At-risk athletes were significantly more likely to experience a noncontact time-loss injury than VB players in the referent group (rate ratio = 6.2; 95% CI, 1.9-17.2; P = .008). The relative risk of sustaining a noncontact time-loss injury to the LQ was 4 times greater in the at-risk group (relative risk = 4.6; 95% CI, 2.1-10.1; P = .01). At-risk athletes were 6 times more likely to experience a foot or ankle injury (relative risk = 6.3; 95% CI, 2.1-19.2; P = .008). CONCLUSION: Suboptimal performance on a battery of functional performance tests is associated with a significantly greater risk of noncontact time-loss injury to the LQ in female Division III college VB players.

Relationships Between Resilience, Mental Well-Being, and COVID-19 Worries in Collegiate Student-Athletes.

The onset of the COVID-19 pandemic was associated with robust declines in well-being for collegiate student-athletes. Worries about COVID-19 have frequently been associated with worsening well-being; therefore, it is important to examine protective factors against well-being decrements. Resilience, one's ability to respond to stress and adversity, may be one such factor. Despite this possible influence, resilience has not yet been studied in student-athletes in this context as the pandemic has progressed. Therefore, the purpose of this study was to examine the moderating role of resilience on the relationship between COVID-19 worries and well-being. In this cross-sectional design, National Collegiate Athletic Association Division III athletes (N = 91) at one university completed surveys on COVID-19 worries, resilience, and well-being between February and March 2021. All competitions had been postponed until the Spring 2021 semester. The findings revealed a negative correlation between COVID-19 worries and well-being (r = -0.21, p = 0.05) and a positive correlation between resilience and well-being (r = 0.44, p < 0.001). Additionally, multiple regression and simple slopes analyses showed that individuals with higher resilience endorsed greater scores of well-being, even when COVID-19 worries increased (ß = 0.38, p = 0.02). In conclusion, our results suggest that resilience had a moderating effect on the relationship between COVID-19 worries and well-being.

Hand and wrist injuries among collegiate athletes vary with athlete division.

BACKGROUND: The rates, severity and consequences of hand and wrist injuries sustained by National Collegiate Athletic Association athletes are not well characterized. This study describes the epidemiology of hand and wrist injuries among collegiate athletes competing in different divisions. METHODS: The National Collegiate Athletic Association Injury Surveillance Program (NCAA-ISP) was accessed from 2004 to 2015 for the following sports: baseball, basketball, football, ice hockey, lacrosse, soccer, wrestling, field hockey, gymnastics, softball and volleyball. The data were used to identify all hand and wrist injuries, the specific injury diagnosis, mean time loss of activity following injury, and need for surgery following injury. These were then stratified by gender. Descriptive statistics were performed to examine the association between sports, event type and division. Student's t test was used to calculate p-values for independent variables. Chi-Square test was used to calculate odds ratio. P < 0.05 was considered significant. RESULTS: 103,098 hand and wrist injuries were reported in in the studied NCAA sports from 2004 to 2015. Male athletes sustained 72,423 injuries (6.01/10,000 athlete exposure) and female athletes sustained 30,675 injuries (4.13/10,000 athlete exposure). Division I athletes sustained significantly more injuries compared to divisions II and III. Overall, 3.78% of hand and wrist injuries required surgical intervention. A significantly higher percentage of division I athletes (both male and female) underwent surgical intervention compared to divisions II and III. The mean time lost due to hand and wrist injury was 7.14 days for all athletes. Division I athletes missed the fewest days due to injury at 6.29 days though this was not significant. CONCLUSIONS: Hand and wrist injuries are common among collegiate athletes. Division I athletes sustain higher rates of injuries and higher surgical intervention rates, while tending to miss fewer days due to injury. Improved characterization of divisional differences in hand and wrist injuries can assist injury management and prevention.

Preseason functional tests discriminate injury risk in female collegiate volleyball players.

OBJECTIVE: Preseason functional tests have been previously associated with noncontact time-loss lower extremity injuries in a variety of athletic populations. This study aimed to determine the effectiveness of one or more functional tests to discriminate injury risk in a cohort of female collegiate volleyball players in the United States. DESIGN: Prospective cohort study. SETTING: National Collegiate Athletic Association Division II & III, National Association of Intercollegiate Athletics female volleyball players; PARTICIPANTS: 130 female volleyball players (mean age: 19.31 ± 1.1 years). MAIN OUTCOME MEASURE: Lower extremity functional test, single limb hop for distance, standing long jump, previous injury history, lower quarter Y-balance test, and limb symmetry index were measured prior to the season beginning. Noncontact time-loss lower quarter injuries were tracked during the season. RESULTS: Athletes with suboptimal scores on the single limb hop test (<70% of height) and standing long jump (<80% of height), combined with a previous history of injury, were three times more likely to sustain an injury during the season (OR = 3.0; 95% CI: 1.09 to 8.30). Individual functional tests did not discriminate injury risk. CONCLUSIONS: A battery of preseason functional tests and injury history discriminates injury risk in female collegiate volleyball players.

Body Size Changes Among National Collegiate Athletic Association New England Division III Football Players, 1956-2014: Comparison With Age-Matched Population Controls.

CONTEXT: Collegiate football programs encourage athletes to pursue high body weights. OBJECTIVE: To examine position-dependent trends over time in body size characteristics among football players in the National Collegiate Athletic Association Division III New England Small College Athletic Conference (NESCAC) from 1956 to 2014 and to compare the observed absolute and relative changes with those in age-matched male population controls. DESIGN: Descriptive laboratory study. SETTING: Medical school affiliated with a NESCAC institution. PATIENTS OR OTHER PARTICIPANTS: Football team rosters from the 10-member NESCAC schools, available as public documents, were analyzed along with body size data from general population males aged 20 to 29 years from the National Health and Nutrition Examination Survey (NHANES). MAIN OUTCOME MEASURE(S): Body weight, height, and calculated body mass index were evaluated using analysis of variance, linear regression, and nonlinear regression to determine the distribution features of size variables and changes associated with time (year), school, and position. RESULTS: Among NESCAC linemen, absolute and relative changes over time in body weight and body mass index exceeded corresponding changes in the NHANES population controls. New England Small College Athletic Conference offensive linemen body weights increased by 37.5% from 1956 to 2014 (192 to 264 lb [86.4 to 118.8 kg]), compared with a 12% increase (164 to 184 lb [73.8 to 82.8 kg]) since 1961 in the NHANES population controls. Body mass index changed in parallel with body weight and exceeded 35 kg/m(2) in more than 30% of contemporary NESCAC offensive linemen. Among skill players in the NESCAC group, time-related changes in body size characteristics generally paralleled those in the NHANES controls. CONCLUSIONS: High body weight and body mass indices were evident in offensive linemen, even among those in Division III football programs with no athletic scholarships. These characteristics may be associated with adverse cardiovascular and metabolic outcomes. We need approaches to encourage risk modification in the postfootball lifestyles of these individuals.
