We have examined the followings ; 1) the low-frequency component of rectified electromyography(EMG) may provide temporal information on the instantaneous rate of force fluctuations(dF/dt) during steady contractions 2) low-frequency component of rectified EMG(<5 Hz) reflects the temporal characteristics and magnitude of the variability of motor unit discharge rate 3) the rectified EMG is associated with the unintended instantaneous rate of force fluctuations(dF/dt) and it's association is enhanced by development of muscle fatigue.

我们已经检查了以下内容； 1）整流肌电图（EMG）的低频成分可能会提供有关稳定收缩期间力瞬时力波动率（DF/DT）的时间信息。波动（DF/DT）及其关联通过肌肉疲劳的发展而增强。
