The effects of high frequency alternating knee flexion-extension on muscle activity of the quadriceps and hamstring muscle groups has been investigated. Standard loads were used for each subject. The muscle activity in vastus medialis, vastus lateralis, rectus femoris and the lateral hamstrings were recorded by electromyography during increasing velocities. Rectus femoris and hamstrings were found to increase their activities significantly with increasing speed while vastus medialis and vastus lateralis showed no such change. The individual thigh muscles thus differ in function in relation to the velocity of movement.
研究了高频交替屈伸膝关节对股四头肌和腘绳肌群肌肉活动的影响。对每个受试者使用标准负荷。在速度增加过程中，通过肌电图记录股内侧肌、股外侧肌、股直肌和外侧腘绳肌的肌肉活动。发现股直肌和腘绳肌的活动随着速度增加而显著增加，而股内侧肌和股外侧肌则没有这种变化。因此，各个大腿肌肉在与运动速度相关的功能上存在差异。
