CONTEXT: High-intensity sport training at the youth level has led to increased concern for overuse conditions. Few researchers have examined overuse conditions in youth sports. OBJECTIVE: To examine the rates, risks, and distributions of overuse conditions between youth and high school football players. DESIGN: Descriptive epidemiologic study. SETTING: Youth and high school football teams. PATIENTS OR OTHER PARTICIPANTS: The Youth Football Safety Study (YFSS) investigated youth football athletes from age 5 to 14 years. The National Athletic Treatment, Injury and Outcomes Network (NATION) focused on high school football athletes 14 to 18 years old. The YFSS data consisted of 210 team-seasons, and the NATION data consisted of 138 team-seasons. MAIN OUTCOME MEASURE(S): Athletic trainers collected football injury and exposure data during the 2012 and 2013 seasons. Injury rates, risks, and distributions were calculated, with injury rate ratios, risk ratios, and injury proportion ratios with 95% confidence intervals (CIs) comparing youth and high school football players. RESULTS: The YFSS reported 1488 injuries, of which 53 (3.6%) were overuse conditions. The NATION reported 12 013 injuries, of which 339 (2.8%) were overuse conditions. The overuse condition rate did not differ between high school and youth football (3.93 versus 3.72/10 000 athlete-exposures; injury rate ratio = 1.06; 95% CI = 0.79, 1.41). However, the 1-season risk of overuse condition was higher in high school than in youth football players (2.66% versus 1.05%; risk ratio = 2.53; 95% CI = 1.84, 3.47). Compared with high school football players, youth football players had greater proportions of overuse conditions that were nontime loss (ie, <24 hours participation-restriction time; 83.0% versus 67.0%; injury proportion ratio = 1.24; 95% CI = 1.07, 1.43) and affecting the lower extremity (92.5% versus 62.5%; injury proportion ratio = 1.48; 95% CI = 1.32, 1.65). CONCLUSIONS: Overuse conditions may not present a primary concern in youth and high school football players. However, differences existed between the 2 levels of competition. Although additional research on the incidence of overuse conditions across all youth and high school sports is needed, these findings may highlight the need for programming that is specific to competition level.
背景：青少年高强度运动训练导致过度使用情况的关注度增加。很少有研究人员研究青少年运动中的过度使用情况。 目的：检查青年和高中足球运动员之间过度使用情况的发生率、风险和分布。 设计：描述性流行病学研究。 设置：青年和高中足球队。 患者或其他参与者：青年足球安全研究（YFSS）调查了 5 至 14 岁的青年足球运动员。国家运动治疗、伤害和结果网络（NATION）专注于 14 至 18 岁的高中足球运动员。YFSS 数据包括 210 个团队赛季，NATION 数据包括 138 个团队赛季。 主要观察指标：在 2012 年和 2013 赛季，运动训练员收集了足球伤害和暴露数据。计算了伤害发生率、风险和分布，使用伤害率比、风险比和伤害比例比及其 95%置信区间（CI）比较青年和高中足球运动员。 结果：YFSS 报告了 1488 例伤害，其中 53 例（3.6%）为过度使用情况。NATION 报告了 12013 例伤害，其中 339 例（2.8%）为过度使用情况。高中和青年足球之间的过度使用情况发生率没有差异（3.93 与 3.72/10000 名运动员暴露；伤害率比=1.06；95%CI=0.79，1.41）。然而，高中足球运动员 1 个赛季过度使用情况的风险高于青年足球运动员（2.66%比 1.05%；风险比=2.53；95%CI=1.84，3.47）。与高中足球运动员相比，青年足球运动员的过度使用情况中，无时间损失（即<24 小时参与限制时间）的比例更大（83.0%比 67.0%；伤害比例比=1.24；95%CI=1.07，1.43），以下肢受伤为主（92.5%比 62.5%；伤害比例比=1.48；95%CI=1.32，1.65）。 结论：过度使用情况可能不是青年和高中足球运动员的主要关注点。然而，在竞争水平之间存在差异。尽管需要对所有青年和高中运动的过度使用情况发生率进行更多研究，但这些发现可能强调需要针对竞争水平制定具体的计划。
