| 摘 要： | 实验表明,速度攀岩运动是非周期性运动,攀岩运动员在速度攀岩的每趟或同一趟的不同时段,他的表面肌电信号都有较大的变化,是显著的非稳定信号。所以,运用表面肌电信号分析速度攀岩运动员的肌肉疲劳问题存在着一定的困难:不能用传统的频阈分析方法去评价相关肌肉的疲劳问题,而只有运用非线性信号分析方法才能较好解决这一问题,然而sEMG非线性信号分析的应用尚属初期探索阶段,有待科研工作者的深入研究。

| 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. |
