Abstract

Experiment shows that rock climbing sport is a nonperodic sport.The surface EMG has great changes in every rock-climbing or different stage of the same rock climbing,which is distinct wavy signal.So,there are full of difficulties to analyze muscle fatigue with surface EMG:can't apply traditional power spectral to appraise correlative muscle fatigue,and only apply nonlinear signal to solve this problem.However,application of nonlinear signal analysis of surface EMG belongs to initial stages.We expect researchers to research deeply.
