To examine the association between generalised joint laxity (GJL) and injury rates in Middle Eastern male youth athletes.
Prospective observational study consisting of GJL screen and injury audit (season 2009/2010).
Aspire Sports Academy Doha, Qatar.
A total of 226 adolescent male athletes (mean age: 14.2 years; SD: 1.7; range: 10-18) involved in 15 sporting activities were grouped into contact and non-contact sports. All available athletes were included in this study.
A seasonal injury audit, athletes' anthropometric characteristics, for example, weight, height and body mass index and screen for GJL to determine Beighton Score (BS).
The 226 athletes sustained 596 injuries and 75% reported at least one injury over a seasonal injury audit. Players in contact sports were injured more often than players in non-contact sports (more frequent injuries than injury-free time in contact sports; 127 days (95% CI 93 to 160) vs 176 days in non-contact sports (95% CI 118 to 234) (p<0.001). Survival analysis showed that gradient BS was not associated with injury HR=1.004 (95% CI 0.95 to 1.06) in the overall cohort. However, BS was associated with a greater injury risk in contact sports (HR: 1.29; 95% CI 1.05 to 1.59; p=0.015).
Greater GJL, defined by gradient BS, plus involvement in contact sports together influence injury risk in youth athletes. Preseason documentation of GJL scoring should be considered specifically for contact sports as injury pre-emptive measure.
研究中东地区男性青少年运动员的关节普遍松弛（GJL）与受伤率之间的关联。
前瞻性观察性研究，包括GJL筛查和损伤审计（2009/2010赛季）。
卡塔尔多哈的阿斯皮雷体育学院。
共有226名青少年男性运动员（平均年龄：14.2岁；标准差：1.7；范围：10 - 18岁）参与15项体育活动，被分为接触性运动和非接触性运动两组。所有可参与的运动员均纳入本研究。
进行季节性损伤审计、运动员人体测量学特征（如体重、身高和体重指数）以及GJL筛查以确定贝ighton评分（BS）。
在季节性损伤审计中，226名运动员共遭受596次损伤，75%的运动员报告至少有一次损伤。接触性运动的运动员比非接触性运动的运动员受伤更频繁（接触性运动中受伤次数多于无受伤时间；127天（95%置信区间93至160），而非接触性运动为176天（95%置信区间118至234）（p<0.001）。生存分析表明，在整个队列中，梯度BS与受伤风险无关，风险比（HR）=1.004（95%置信区间0.95至1.06）。然而，在接触性运动中，BS与更高的受伤风险相关（HR：1.29；95%置信区间1.05至1.59；p = 0.015）。
由梯度BS定义的更高的GJL，加上参与接触性运动，共同影响青少年运动员的受伤风险。作为一种损伤预防措施，应特别考虑为接触性运动在赛季前记录GJL评分。
