The aim of this study was to identify the intrinsic factors that could increase risk of shoulder pain in adolescent volleyball players. Twenty-eight young male volleyball players (between 14 and 18 years old) participated in this study. Athletes were submitted to: isokinetic muscle strength assessment of shoulder rotator muscles, ball service speed assessment, anterior and posterior drawer test, apprehension test, groove sign and scapular dyskinesia test. Athletes were followed for 16 weeks to monitor the presence of shoulder pain. All athletes were submitted to the same training protocol. During the 16 weeks, 28.5% of the athletes (n=8) experienced shoulder pain in the dominant limb higher than 3 according to Numerical Rating Scale criteria; 71.5% of the athletes (n=20) did not experience pain, or pain equal or lower than 3. The main result of our study was that the odds of feeling pain higher than 3 was significantly higher among players who presented higher values for internal rotation peak torque (OR=1.113, CI 95%=1.006 to 1.232 and p=0.038). The odds of feeling pain increased by 11% for every N·m of the internal rotator muscles. Pre-season isokinetic rotator strength assessments can help identify adolescent volleyball players at increased risk of a shoulder injury.
本研究的目的是确定可能增加青少年排球运动员肩部疼痛风险的内在因素。28名年轻男性排球运动员（年龄在14至18岁之间）参与了本研究。运动员接受了：肩部旋转肌等速肌力评估、发球速度评估、前后抽屉试验、恐惧试验、沟征和肩胛运动障碍试验。对运动员进行了16周的随访，以监测肩部疼痛的情况。所有运动员都遵循相同的训练方案。在这16周内，根据数字评分量表标准，28.5%的运动员（n = 8）优势肢体肩部疼痛高于3级；71.5%的运动员（n = 20）没有经历疼痛，或疼痛程度等于或低于3级。我们研究的主要结果是，内旋峰值扭矩值较高的运动员中，疼痛高于3级的几率显著更高（OR = 1.113，95%置信区间 = 1.006至1.232，p = 0.038）。内旋肌每增加1 N·m，疼痛几率增加11%。赛季前的等速旋转肌力量评估有助于识别肩部受伤风险增加的青少年排球运动员。
