The purpose of this study was to find out whether fatiguing calf-muscle exercise affects postural sway during standing. Thirteen healthy subjects with a mean age of 25 years participated. Body sway in one leg stance was measured on a force plate before and after fatiguing exercises of the calf muscles of the subject's right leg. Repeated measurements for up to 10 min after exercises showed no increase of body sway. The results indicate that postural control in quiet standing can be maintained by compensatory mechanisms activated during muscle fatigue. A significant decrease of body sway over time on the non-fatigued leg, indicated a learning effect. A similar decrease was not observed on the fatigued leg, indicating interference of compensatory mechanisms on learning.
本研究的目的是探究疲劳的小腿肌肉运动是否会影响站立时的姿势摇摆。13名平均年龄为25岁的健康受试者参与了研究。在对受试者右腿小腿肌肉进行疲劳运动前后，使用测力板测量单腿站立时的身体摇摆。运动后长达10分钟的重复测量显示身体摇摆没有增加。结果表明，安静站立时的姿势控制可通过肌肉疲劳期间激活的代偿机制得以维持。未疲劳侧腿的身体摇摆随时间显著下降，表明存在学习效应。而在疲劳侧腿上未观察到类似的下降，这表明代偿机制对学习存在干扰。
