安静及疲劳状态下运动电位的研究

Study on Motion Potential at Rest and Fatigue

本文以肌电触发生物信号处理系统,对单极点脑电作100次逆叠加,得到受试者安静与疲劳状态下屈腕时的运动电位参数,以探讨运动电位与训练的关系。本文提示:运动电位的时程、幅值可作为评定训练程度和疲劳时的脑功能指标。

Motor potential parameters of subjects at rest and fatigue with elbow bent, are obtained by means of triggering biological signal processing system with electromyograph and counter-overlapping electroencephalograms of single electrode 100 times. Thus the relationship between motor potential and training is analyzed. This paper points out that the time duration and double amplitude of motor potential could be used as the indices to evaluate the training extent and the brain function at fatigue.
