The short latency stretch-reflex component (M1) and its interactions with muscle stiffness and with muscle performance were investigated before and after long-term stretch-shortening cycle (SSC) exercise. Dramatic fatigue induced reduction in maximal SSC performance capability, and electromyographic activity was accompanied by a consistent decrease in the M1 reflex component and eccentric peak stiffness of the muscle. It can be suggested, therefore, that the decreased muscle performance is not simply a direct effect of central or peripheral fatigue, but is partly due to impairment of the ability to utilize stiffness-related elastic energy.
研究了长期伸展-缩短循环（SSC）运动前后短潜伏期牵张反射成分（M1）及其与肌肉僵硬度和肌肉性能的相互作用。剧烈疲劳导致最大SSC运动能力下降，肌电图活动伴随着M1反射成分和肌肉离心峰值僵硬度的持续降低。因此，可以认为肌肉性能下降并非仅仅是中枢或外周疲劳的直接影响，部分原因是利用与僵硬度相关的弹性能量的能力受损。
