Abstract

The purpose of this study was through the fractal dimension analysis of an elite 100M ahtlete EMG signals before and after the competition. Results showed that the fractal dimension of athlete’s EMG signals were apparently different at different training states. In addition the fractal dimension of athlete’s EMG signals were identical at the different training loads. The fractal dimension of EMG signals from different muscle groups of the same athlete accomplishing the same movement were relatively stable. However the fractal dimension of EMG signals at different contractile states of muscles were apparently different at the same training phase.
