疲劳对骨骼肌舒张性能的影响比对收缩性能的影响更显著。
The effects of fatigue on skeletal muscle relaxation ability is more serious than on contractibility.
骨骼肌间断强直收缩期间，当刺激间隔缩短到一定程度时，收缩张力呈现逐步降低，即产生疲劳现象。
Fatigue occurs when the interval of intermittent tetanic contraction of skeletal muscle is shortened to a certain degree and the contractile tension declines.
