The effectiveness on the muscle expansion and the mechanism of "slow training" which puts a slow burden on muscles in slow operation were investigated. In this research, the frequency analysis of electromyography and investigation of the density of oxygenated hemoglobin in muscles were conducted to clarify the characteristics of the slow training which are different from the conventional training with high burden on muscles, in terms of the activation level of the fast-twitch fiber in muscles of legs. In these investigations, it was clarified that the cumulative value of electromyography during the training is relatively high, and the effectiveness of muscular expansion by the slow training is remarkable, like the conventional training. In addition to this, it was clarified that the fast twitch fiber was activated during the slow training because the power level of high frequency in the FFT analysis of electromyography is relatively high and the oxygenated hemoglobin is relatively low in muscles.
