���チャンネル表面筋電図伝播波解析による速筋線維活動評価の検討

It is significant to evaluate the recruitment of fast twitch fibers quantitively in means of preventing sarcopenia. In a previous study, m-ch method was proposed to observe propagation wave which originates from action potential of each muscle fiber. In this study, relation between strength of muscle contraction and propagation wave had been examined in purpose of evaluating recruitment of fast twitch fibers during training. The result suggests that most propagation waves acquired band's velocity has increased by increase of muscle contraction strength. There is a hope for evaluating recruitment of fast twitch fibers during training.
