Epidemiology of National Collegiate Athletic Association Men's and Women's Cross-Country Injuries, 2009–2010 Through 2013–2014

Abstract

Context: Recent injury-surveillance data for collegiate-level cross-country athletes are limited.Objective: To describe the epidemiology of National Collegiate Athletic Association (NCAA) men's and women's crosscountry injuries during the 2009-2010 through 2013-2014 academic years.Design: Descriptive epidemiology study. Setting: Aggregate injury and exposure data collected from 25 men's and 22 women's cross-country programs, providing 47 and 43 seasons of data, respectively.Patients or Other Participants: Collegiate student-athletes participating in men's and women's cross-country during the 2009-2010 through 2013-2014 academic years.Main Outcome Measure(s): Injury rates; injury rate ratios (RRs); injury proportions by body site, diagnosis, and apparatus; and injury proportion ratios were reported with 95% confidence intervals (CIs).Results: The Injury Surveillance Program captured 216 injuries from men's cross-country and 260 injuries from women's cross-country, leading to injury rates of 4.66/1000 athleteexposures (AEs) for men (95% CI ¼ 4.04, 5.28) and 5.85/1000 AEs for women (95% CI ¼ 5.14, 6.56). The injury rate in women's cross-country was 1.25 times that of men's cross-country (95% CI ¼ 1.05, 1.50). Most injuries affected the lower extremity (men ¼ 90.3%, women ¼ 81.9%). The hip/groin-injury rate in women (0.65/1000 AEs) was higher than that in men (0.15/1000 AEs; RR ¼ 4.32; 95% CI ¼ 1.89, 9.85). The ankle-injury rate in men (0.60/ 1000 AEs) was higher than that in women (0.29/1000 AEs; RR ¼ 2.07; 95% CI ¼ 1.07, 3.99). Common diagnoses were strains (men ¼ 19.9%, women ¼ 20.4%) and inflammation (men ¼ 18.1%, women ¼ 23.8%). The majority of injuries were classified as overuse (men ¼ 57.6%, women ¼ 53.3%).Conclusions: Consistent with prior research, injury distributions varied between male and female athletes, and the injury rate among females was higher. Understanding the epidemiology of these cross-country injuries may be important for developing appropriate preventive interventions.Key Words: injury prevention, collegiate sports, distance running Key PointsOur findings indicate a lower injury burden in men's and women's cross-country than previously reported. The injury rate in women's cross-country was 1.25 times that of men's cross-country. Most injuries affected the lower extremity and were diagnosed as strains and inflammation.

Epidemiology of 3825 injuries sustained in six seasons of National Collegiate Athletic Association men's and women's soccer (2009/2010–2014/2015)

“…In studies using recent NCAA-ISP data, non-time-loss injuries comprised a range of 58.8% (women's cross country) to 77.2% (men's swimming and diving) of all reported injuries 24 25. These percentages of non-time-loss injuries are markedly higher than what we found in our investigation.…”

Physiological and Biomechanical Responses to Running on Lower Body Positive Pressure Treadmills in Healthy Populations

“…Running may be viewed as a healthy activity because it ultimately provides cardiometabolic benefits, but lower extremity musculoskeletal overuse injuries are very common in runners at various competitive levels [1,2]. Epidemiological data also demonstrate that running is the most frequent cause of exercise-and sport-related injuries in the military [3].…”

Achilles tendon adaptation in cross‐country runners across a competitive season

“…must also be considered as contributing to overall training load. A recent study by Kerr et al . found that the majority of injuries in collegiate cross‐country are of an overuse mechanism, which is often attributed to errors in cumulative load management.…”
