Our primary aim was to determine if athletic identity is prospectively associated with shoulder overuse injuries. Secondly, we aimed to determine if athletic identity is prospectively associated with playing through pain and to describe how athletic identity relates to sex, age, playing level, weekly training load, and match volume.
A cohort of 269 adolescent tennis players were followed over a period of 52 weeks. Cox regression was used to estimate the hazard rate ratio (HRR) of first-time shoulder overuse injury associated with every 10-unit increase on the Athletic Identity Measurement Scale (AIMS).
The adjusted HRR of shoulder overuse injury was 0.89 (95% CI: 0.36-2.20) and the odds ratio of playing through pain was 2.41 (95% CI: 0.74-8.96) for every 10 unit increase on AIMS. The level of athletic identity was higher among players at the national level than among players at the regional level and was weakly correlated to weekly hours of tennis matches, tennis training, and fitness training.
Our results indicate that higher levels of athletic identity may be associated with a lower incidence of shoulder overuse injuries, and potentially with playing through pain, although these results are inconclusive due to wide confidence intervals.
我们的主要目的是确定运动身份是否与肩部过度使用损伤存在前瞻性关联。其次，我们旨在确定运动身份是否与忍痛参赛存在前瞻性关联，并描述运动身份与性别、年龄、比赛水平、每周训练负荷和比赛量之间的关系。
对269名青少年网球运动员进行了为期52周的跟踪研究。使用Cox回归来估计运动身份测量量表（AIMS）每增加10个单位与首次肩部过度使用损伤相关的风险率比（HRR）。
AIMS每增加10个单位，肩部过度使用损伤的调整后HRR为0.89（95%置信区间：0.36 - 2.20），忍痛参赛的优势比为2.41（95%置信区间：0.74 - 8.96）。国家级运动员的运动身份水平高于地区级运动员，且与每周网球比赛时长、网球训练和体能训练呈弱相关。
我们的结果表明，较高水平的运动身份可能与较低的肩部过度使用损伤发生率相关，并且可能与忍痛参赛有关，尽管由于置信区间较宽，这些结果尚无定论。
