The purpose of this study was to evaluate the side-to-side differences of isokinetic muscle torque during shoulder rotation in healthy nonathletic subjects. The strength was examined at two angles of glenohumeral abduction in the scapular plane (45 degrees and 90 degrees, respectively) and at three velocities (180 degrees/s, 120 degrees/s, 60 degrees/s) using Biodex System 3Pro dynamometer. The maximal torques were achieved on dominant side in 45-degree abduction at 60 degrees/s velocity, both for external and internal rotation. A general pattern was observed: abduction angle and velocity increase provoked a decrease in torque values, but each antagonistic muscle group was sensitive to a different factor. Significant differences between dominant and non-dominant limb were not observed in nonathletic male.
本研究的目的是评估健康非运动员受试者在肩部旋转过程中等速肌肉扭矩的左右差异。使用Biodex System 3Pro测力计，在肩胛平面内的两个盂肱外展角度（分别为45度和90度）以及三种速度（180度/秒、120度/秒、60度/秒）下检测力量。在60度/秒的速度下，45度外展时，无论是外旋还是内旋，优势侧均获得最大扭矩。观察到一个总体模式：外展角度和速度增加会导致扭矩值降低，但每个拮抗肌群对不同因素敏感。在非运动员男性中未观察到优势侧和非优势侧肢体之间的显著差异。
