There is a lack of injury data for the new Olympic sport of Rugby-7s, particularly for involved youth.
To determine injury rates and characteristics for players participating in U.S. Rugby-7s U19 (under 19 years of age) tournaments.
Injury data were collected, using the Rugby Injury Survey & Evaluation report methodology, at 24 U.S. Rugby-7 s U19 tournaments over 30 tournament days (2010-2014). Tournament medical-attention injuries and time-loss injuries (days absent before return to training/competition including post tournament) were recorded.
During the 2101 playing hours (3072 males, aged 17.2 ± 1.5 years; 732 females, 16.6 ± 1.3 years of age), there were 173 tournament injuries with an overall injury incidence of 82.4/1000 player-match-hours (ph) (CI 70.5-95.6). Acute injuries (79.5/1000 ph) occurred during tackling (56.2/1000 ph) and involved joints/ligaments (32.8/1000 ph) of lower extremities (31.9/1000 ph). Head and neck injuries, including concussions, were common (males 21.9/1000 ph; females 22.0/1000 ph). Medical-attention injury incidences (49.5/1000 ph; n = 104; 95% CI 40.5-60.0) were higher than time loss (32.8/1000 ph; n = 69; 95% CI 25.5-41.6). Overall, injury incidences found no difference between sex (RR 0.78; p = 0.369). Time-loss injuries resulted in an average of 35.5 d to return to sport.
This study is the first to report match injury incidences for U19 participants in Rugby-7s. Overall, match injury incidence among U.S. U19 Rugby-7s tournaments was similar compared to adult U.S. community Rugby-7s. Recurrent injury risk was notable in this population. Community injury surveillance studies are essential to understand risk from participation in amateur sports. Knowledge of these injury patterns in U19 Rugby-7s will help identify areas to direct resources to enable growth of Rugby-7s in youths and emerging countries being exposed to Rugby-7 s. Age-based injury frequency and patterns in rugby and its various formats are needed for the development of evidence-based, sport-specific, and population-specific injury prevention initiatives.
The match injury incidence of U19 participants in U.S. Rugby-7s was similar to the incidence among adult participants. Recurrent match injury risk was high at 23%. There were no significant differences in injury incidences between males and females. The first three matches of a tournament day result in the most injuries.
新的奥运会项目七人制橄榄球缺乏损伤数据，尤其是涉及青少年的相关数据。
确定参加美国U19（19岁以下）七人制橄榄球锦标赛球员的损伤发生率及特征。
采用橄榄球损伤调查与评估报告方法，在2010 - 2014年的30个比赛日里，于24场美国U19七人制橄榄球锦标赛中收集损伤数据。记录比赛中需要医疗关注的损伤以及导致缺训/缺赛的损伤（包括赛后缺训/缺赛天数）。
在2101个比赛小时期间（男性3072人，年龄17.2±1.5岁；女性732人，年龄16.6±1.3岁），共有173例比赛损伤，总体损伤发生率为82.4/1000运动员比赛小时（ph）（可信区间70.5 - 95.6）。急性损伤（79.5/1000 ph）发生在擒抱时（56.2/1000 ph），累及下肢关节/韧带（32.8/1000 ph）。头部和颈部损伤，包括脑震荡，很常见（男性21.9/1000 ph；女性22.0/1000 ph）。需要医疗关注的损伤发生率（49.5/1000 ph；n = 104；95%可信区间40.5 - 60.0）高于导致缺训/缺赛的损伤发生率（32.8/1000 ph；n = 69；95%可信区间25.5 - 41.6）。总体而言，损伤发生率在性别之间无差异（相对危险度0.78；p = 0.369）。导致缺训/缺赛的损伤平均使运动员35.5天无法恢复比赛。
本研究首次报告了U19七人制橄榄球参与者的比赛损伤发生率。总体而言，美国U19七人制橄榄球锦标赛中的比赛损伤发生率与美国成人社区七人制橄榄球的发生率相似。在这一人群中，反复损伤风险显著。社区损伤监测研究对于了解参与业余运动的风险至关重要。了解U19七人制橄榄球中的这些损伤模式将有助于确定资源投入方向，以促进七人制橄榄球在青少年和新兴国家的发展。为制定基于证据、针对特定运动和特定人群的损伤预防措施，需要了解橄榄球及其各种形式基于年龄的损伤频率和模式。
美国U19七人制橄榄球参与者的比赛损伤发生率与成人参与者的发生率相似。反复比赛损伤风险高达23%。男性和女性的损伤发生率无显著差异。比赛日的前三场比赛导致的损伤最多。
