摘要
使用CYBEX—6000型测力系统,对膝关节不同起始角和结束角运动的肌力进行测试,获得了在 60°/s、180°/s和 300°/s 3种速度下,9种不同起始膝角、结束膝角、运动幅度中,屈伸膝肌群的峰力矩、总功、平均功率等参数,并进行了分析研究。发现屈伸膝肌群的峰力矩、总功和平均功率均随着运动幅度的增大而增大。
Knee muscular force of nine kinds of start-angles and end-angles were tested with Cybex 6000 and the peak tprque, total work and average power of knee flexors and extensors at 60°/s,180°/s and 300°/s were obtained. The results showed that with the movement ranges increasing, the peak torque, total work and average power of knee flexors and extensors displayed an increasing pattern.
