OBJECTIVES
To evaluate the differences in strength and mobility of shoulder rotator muscles in the dominant and non-dominant shoulders of elite volleyball players.
METHODS
Isokinetic muscle strength tests were performed at speeds of 60 and 120 degrees/s, and shoulder mobility was examined in ten players from the England national men's volleyball squad. The subjects also completed a questionnaire that included a visual prompt and analogue pain scale.
RESULTS
The range of motion of internal rotation on the dominant side was less than that on the non-dominant side (p < 0.01). The average peak strength at 60 degrees/s external eccentric contraction was lower than that of internal concentric contraction in the dominant arm, but was higher in the non-dominant arm. Six of the ten subjects reported a shoulder problem, described as a diffuse pain located laterally on the dominant shoulder.
CONCLUSIONS
These elite volleyball players had a lower range of motion (internal rotation) and relative muscle imbalance in the dominant compared with the non-dominant shoulder.
目的
评估精英排球运动员优势肩和非优势肩旋转肌群的力量及活动度差异。
方法
对来自英格兰国家男子排球队的10名运动员进行了60度/秒和120度/秒速度下的等速肌力测试，并检查了肩部活动度。受试者还完成了一份包含视觉提示和模拟疼痛量表的问卷。
结果
优势侧内旋活动范围小于非优势侧（p<0.01）。优势臂在60度/秒外展离心收缩时的平均峰值力量低于内收向心收缩时，但非优势臂则更高。10名受试者中有6人报告存在肩部问题，表现为优势肩外侧弥漫性疼痛。
结论
与非优势肩相比，这些精英排球运动员优势肩的活动范围（内旋）较小且存在相对肌肉失衡。
