摘要
本文通过对全国 10 0 m跑比赛冠军周伟破男子 10 0 m跑全国纪录前后肌电信号的分形分维分析发现 ,运动员在不同训练状态时 ,肌电信号的分形维数明显不同 ;不同负荷的肌电信号的分形维数基本相同 ;同一运动员完成同一动作时的不同肌群的肌电信号的分形维数也相对稳定 ;在同一训练阶段 ,肌肉在不同收缩状态的肌电信号的分形维数也明显不同。
Through the fractal dimension analysis on Zhou Wei's EMG signals before and after the competition, the author found that the fractal dimension of athlete's EMG signals were apparently different at the different training state; the fractal dimension of athlete's EMG signals were fundamentally identical; the fractal dimension of EMG signals from different muscle groups of the same athlete accomplishing the same movement are relatively stable; the fractal dimension of EMG signals at different contractile states of muscles are apparently different.
