Overuse injuries (injuries due to repetitive loads with inadequate rest) can negatively affect high school athletes, but limited data exist on the effect of sports participation outside of the school-sanctioned season on the development of overuse injuries.
Compare overuse injury patterns among high school athletes who participate in extrascholastic athletics to those participating only in scholastic sports.
Descriptive cross-sectional, secondary analysis of injury data collected on high school athletes across 22 sports over the 2009-2010 through 2015-2016 academic years.
Deidentified data collected as part of the High School Reporting Information Online study (HS RIO).
High school athletes from a large convenience sample of U.S. high schools.
Injury proportion ratios (IPRs) were computed overall and for individual sports to compare the proportion of overuse injuries in athletes competing in extrascholastic sports to athletes participating only in scholastic athletics.
Overall, extrascholastic athletes experienced a higher proportion of overuse injuries compared to scholastic-only athletes (IPR = 1.21, 95% confidence interval [CI] 1.13-1.30), but this association varied by sport. Among extrascholastic athletes, a higher proportion of overuse injuries occurred in those simultaneously playing the same sport outside the school setting (IPR = 1.32, 95% CI 1.11-1.57) as well as having experienced an injury within the past year (IPR = 1.63, 95% CI 1.36-1.95) compared to those sustaining non-overuse injuries.
Overuse injuries were associated with extrascholastic athletics and occurred in higher proportion in extrascholastic athletes who were playing the same sport in more than one league.
过度使用损伤（因重复负荷而导致的损伤，且休息不充分）会对高中生运动员产生负面影响，但关于校外体育活动对过度使用损伤发展的影响的数据有限。
比较参加校际体育活动和仅参加校内体育活动的高中生运动员过度使用损伤的模式。
对 2009-2010 学年至 2015-2016 学年期间 22 项运动的高中生运动员的损伤数据进行描述性横断面、二次分析。
从“高中报告信息在线研究（HS RIO）”中收集的匿名数据。
来自美国大量便利抽样的高中生运动员。
计算总体和个别运动的损伤比例比（IPR），以比较参加校外运动的运动员与仅参加校内运动的运动员过度使用损伤的比例。
总体而言，与仅参加校内运动的运动员相比，参加校外运动的运动员过度使用损伤的比例更高（IPR=1.21，95%置信区间[CI]1.13-1.30），但这种关联因运动而异。在参加校外运动的运动员中，与未遭受过度使用损伤的运动员相比，同时在校外同一运动中受伤（IPR=1.32，95%CI 1.11-1.57）以及在过去一年中受伤过（IPR=1.63，95%CI 1.36-1.95）的运动员中，过度使用损伤的比例更高。
过度使用损伤与校外体育活动有关，在参加同一运动的运动员中，参加多个联赛的运动员过度使用损伤的比例更高。
