Among US collegiate soccer players, the incidence rate and the event characteristics of hamstrings strains differ between sexes, but comparisons in the return-to-participation (RTP) time have not been reported.
To compare the RTP time between male and female collegiate soccer players and analyze the influence of event characteristics on the RTP time for each sex.
Descriptive epidemiology study.
Data were collected from collegiate teams that voluntarily participated in the National Collegiate Athletic Association Injury Surveillance System.
Collegiate soccer athletes who sustained 507 hamstrings strains (306 men, 201 women) during the 2004 through 2009 fall seasons.
MAIN OUTCOME MEASURE(S): Nonparametric statistics were used to evaluate RTP time differences between sexes and among categories of each event characteristic (ie, time of season, practice or competition, player position). Negative binomial regression was used to model the RTP time for each sex. All analyses were performed separately for first-time and recurrent strains.
We found no differences in the RTP time between sexes for first-time (median: men = 7.0 days, women = 6.0 days; P = .07) or recurrent (median: men = 11 days, women = 5.5 days; P = .06) hamstrings strains. For male players with first-time strains, RTP time was increased when the strain occurred during competition or the in-season/postseason and varied depending on the division of play. Among female players with first-time strains, we found no differences in RTP time within characteristics. For male players with recurrent hamstrings strains, the RTP time was longer when the injury occurred during the in-season/postseason. Among female players with recurrent strains, RTP time was longer for forwards than for midfielders or defenders.
Although we found no differences in the RTP time after hamstrings strains in male and female collegiate soccer players, each sex had unique event characteristics that influenced RTP time.
在美国大学足球运动员中，腘绳肌拉伤的发生率和事件特征存在性别差异，但尚未有关于恢复参赛（RTP）时间的比较报道。
比较男女大学足球运动员的RTP时间，并分析事件特征对各性别RTP时间的影响。
描述性流行病学研究。
数据收集自自愿参与美国国家大学体育协会伤病监测系统的大学球队。
在2004年至2009年秋季赛季期间遭受507次腘绳肌拉伤的大学足球运动员（306名男性，201名女性）。
采用非参数统计评估性别之间以及每个事件特征类别（即赛季时间、训练或比赛、球员位置）内的RTP时间差异。使用负二项回归对各性别的RTP时间进行建模。所有分析均针对首次拉伤和复发性拉伤分别进行。
我们发现，首次（中位数：男性 = 7.0天，女性 = 6.0天；P = 0.07）或复发性（中位数：男性 = 11天，女性 = 5.5天；P = 0.06）腘绳肌拉伤的RTP时间在性别之间没有差异。对于首次拉伤的男性球员，当拉伤发生在比赛期间或赛季中/季后赛时，RTP时间会增加，并且会因比赛级别而有所不同。在首次拉伤的女性球员中，我们未发现各特征内RTP时间存在差异。对于复发性腘绳肌拉伤的男性球员，当损伤发生在赛季中/季后赛时，RTP时间更长。在复发性拉伤的女性球员中，前锋的RTP时间比中场球员或后卫更长。
尽管我们发现男女大学足球运动员腘绳肌拉伤后的RTP时间没有差异，但每种性别都有影响RTP时间的独特事件特征。
