Abstract: In this study, the change with muscle training of muscule strength, muscle hypertrophy and muscular action potential were investigated by the frequency of electromyograph as the directive system on muscle contraction. The subjects were five students, and their flexors of upper arm were trained by 70% of maximal voluntary strength. The results were as follows. 1. The musle strength increased significantly 4.48kg, 19.38% (p<0.01), and the cross-sectional area in upper arm increased significantly 2.4lcm2, 5.52% (p<0.05). 2. The frequency components separated two phases, one of them was low pass filter hand (LFD : 20-40Hz) in relation to tonic contraction and the other was high pass filter band (HFB : 80-140Hz) in relation to dynaamic contractino. Both components in creased significantly, LFB increased remarkably. 3. With muscle training, the frequency components at 70%MVS did't change. Therfore, it was recognized that the intensity and the road of training was adjstment.
