The purpose of this investigation was to examine age-related differences in absolute and relative isokinetic shoulder strength of high school wrestlers. A total of 122 high school wrestlers (M age = 16.31±1.18 yrs) volunteered to be measured for arm flexion and extension strength at the shoulder joint using a Cybex II dynamometer at 30, 180, and 300°·s-1. The sample was divided into four age groups: 13.75-15.00 (n = 22), 15.08-16.00 (n = 27), 16.08-17.00 (n = 34), and 17.08-18.83 years (n = 39). The results of this study indicated significant increases in absolute and relative arm flexion and extension strength across age when covaried for BW and FFW. In addition, comparisons with previously published data indicated differences between muscle groups in the pattern of strength gains that were dependent upon the speed of muscular contraction and may have been influenced by fiber type distribution characteristics.
本研究的目的是调查高中摔跤运动员绝对和相对等速肩部力量的年龄相关差异。共有122名高中摔跤运动员（平均年龄 = 16.31±1.18岁）自愿使用Cybex II测力计在30、180和300°·s-1的速度下测量肩关节的手臂屈伸力量。样本分为四个年龄组：13.75 - 15.00岁（n = 22）、15.08 - 16.00岁（n = 27）、16.08 - 17.00岁（n = 34）和17.08 - 18.83岁（n = 39）。本研究结果表明，在对体重和去脂体重进行协变量调整后，绝对和相对手臂屈伸力量随年龄显著增加。此外，与先前发表的数据比较表明，肌肉群在力量增长模式上存在差异，这取决于肌肉收缩速度，并且可能受纤维类型分布特征的影响。
