Few researchers have examined the rates and patterns of quadriceps strains in student-athletes in the National Collegiate Athletic Association (NCAA).
To describe the epidemiology of quadriceps strains in 25 NCAA sports during the 2009-2010 through 2014-2015 academic years.
Descriptive epidemiology study.
Convenience sample of NCAA programs from 25 sports during the 2009-2010 through 2014-2015 academic years. Patients or Other Particpants: Collegiate student-athletes participating in men's and women's NCAA athletics during the 2009-2010 through 2014-2015 academic years.
MAIN OUTCOME MEASURE(S): Aggregate quadriceps strain injury and exposure data from the NCAA Injury Surveillance Program during the 2009-2010 through 2014-2015 academic years were analyzed. Quadriceps strain injury rates and injury rate ratios (IRRs) were reported with 95% confidence intervals (CIs).
Overall, 517 quadriceps strains were reported, resulting in an injury rate of 1.07/10 000 athlete-exposures (AEs). The sports with the highest overall quadriceps strain rates were women's soccer (5.61/10 000 AEs), men's soccer (2.52/10 000 AEs), women's indoor track (2.24/10 000 AEs), and women's softball (2.15/10 000 AEs). Across sex-comparable sports, women had a higher rate of quadriceps strains than men overall (1.97 versus 0.65/10 000 AEs; IRR = 3.03; 95% CI = 2.45, 3.76). The majority of quadriceps strains were sustained during practice (77.8%). However, the quadriceps strain rate was higher during competition than during practice (1.29 versus 1.02/10 000 AEs; IRR = 1.27; 95% CI = 1.03, 1.56). Most quadriceps strains occurred in the preseason (57.8%), and rates were higher during the preseason compared with the regular season (2.29 versus 0.63/10 000 AEs; IRR = 3.60; 95% CI = 3.02, 4.30). Common injury mechanisms were noncontact (63.2%) and overuse (21.9%). Most quadriceps strains restricted participation by less than 1 week (79.3%).
Across 25 sports, higher quadriceps strain rates were found in women versus men, in competitions versus practices, and in the preseason versus the regular season. Most quadriceps strains were minor in severity, although further surveillance is needed to better examine the risk factors associated with incidence and severity.
很少有研究人员调查过美国大学体育协会（NCAA）学生运动员的股四头肌拉伤发生率和模式。
描述2009 - 2010学年至2014 - 2015学年期间25项NCAA运动项目中股四头肌拉伤的流行病学情况。
描述性流行病学研究。
2009 - 2010学年至2014 - 2015学年期间25项运动项目的NCAA项目便利样本。患者或其他参与者：2009 - 2010学年至2014 - 2015学年期间参加NCAA男子和女子体育赛事的大学生运动员。
分析了2009 - 2010学年至2014 - 2015学年期间NCAA损伤监测项目的股四头肌拉伤损伤和暴露数据。报告了股四头肌拉伤发生率和损伤率比（IRR），并给出95%置信区间（CI）。
总体而言，共报告了517例股四头肌拉伤，损伤率为1.07/10000运动员暴露次数（AE）。总体股四头肌拉伤率最高的运动项目是女子足球（5.61/10000 AE）、男子足球（2.52/10000 AE）、女子室内田径（2.24/10000 AE）和女子垒球（2.15/10000 AE）。在性别可比的运动项目中，总体而言女性股四头肌拉伤率高于男性（1.97对0.65/10000 AE；IRR = 3.03；95% CI = 2.45，3.76）。大多数股四头肌拉伤发生在训练期间（77.8%）。然而，比赛期间的股四头肌拉伤率高于训练期间（1.29对1.02/10000 AE；IRR = 1.27；95% CI = 1.03，1.56）。大多数股四头肌拉伤发生在季前赛（57.8%），且季前赛的发生率高于常规赛（2.29对0.63/10000 AE；IRR = 3.60；95% CI = 3.02，4.30）。常见的损伤机制是非接触性（63.2%）和过度使用（21.9%）。大多数股四头肌拉伤导致的参赛受限时间少于1周（79.3%）。
在25项运动项目中，女性的股四头肌拉伤率高于男性，比赛期间高于训练期间，季前赛高于常规赛。大多数股四头肌拉伤严重程度较轻，不过需要进一步监测以更好地研究与发病率和严重程度相关的风险因素。
