SHOULDER ISOKINETIC PERFORMANCE IN HEALTHY PROFESSIONA JUDO ATHLETES: NORMATIVE DATAS

ABSTRACT Objective: To evaluate normative data of shoulder isokinetic strength in healthy professional judo athletes. Methods: Cross-sectional study with 20 professional male and female athletes (10 female), evaluated with an isokinetic dynamometer. The strength assessment was carried out in external and internal rotation, flexion, extension, adduction and abduction. All data collected on muscle torque were normalized with body mass index. Results: Athletes demonstrated higher peak torque and joint work in shoulder adduction, abduction, flexion, and extension for the dominant limb compared to the non-dominant limb (p <0.05), with most of these deficits below 10%. Shoulder internal/external rotation ratios for male and female athletes had no significant differences between dominant and non-dominant sides, demonstrating values at 60°/s of 49.4 ± 7.2 on the dominant side of males and 49.1 ± 4.9 for females. Conclusion: The normative data are described to assist during treatment, return to sport and injury prevention. Level of evidence IV, cross-sectional study.

摘要
研究目的：评估健康职业柔道运动员的肩部等速肌力常模数据。
方法：本研究为横断面研究，纳入20名职业男女运动员（女性10名），采用等速测力仪（isokinetic dynamometer）进行评估。肌力评估涵盖肩内旋、外旋、屈曲、伸展、内收与外展动作。所有肌肉扭矩数据均以身体质量指数（body mass index, BMI）进行标准化处理。
结果：与非优势侧肢体相比，运动员优势侧肩部内收、外展、屈曲及伸展的峰扭矩与关节功更高（p<0.05），多数组间差值低于10%。男女运动员的肩内/外旋比值在优势侧与非优势侧间无显著差异；男性优势侧在60°/s测试速度下的比值为49.4±7.2，女性为49.1±4.9。
结论：本研究所得的肩部等速肌力常模数据，可辅助临床治疗、运动回归及运动损伤预防。本研究为横断面研究，证据等级为IV级。
