The Changes of SEMG in Progressively Load Exercise

Xiaoli Liu

Abstract

The detection of surface EMG signal is a noninvasive method,which has great importance in clinical diagnosis rehabilitation medicine and sport medicine The amplitude and power spectrum of EMG will change while muscle fatigue will develop.Muscular fatigue refers to temporary decline of maximal power ability or contractive ability for muscle movement system.The signal of SEMG can reflect the change of muscular fatigue at certain extent.Surface EMG will play an important role in studying athletic muscle fatigue.
