There is a view that the brain wave on head skin become to a α-wave from β-wave with proficiency of motor. this cause is that the fall of consciousness level in cerebrum cortex, in over word motor control system moves into subcortex. And, in another view a loop connection in between cerebrum and cerebellum or channels in central nervous which includes basal ganglia draw up the program of motor models. The author thought as a following hypothesis that both views are difference between a phemomenon and a mechanism on shilled process of motor and are ultimately same structure. On basis of this hypothesis six male students were trained one minut at a time, five times per a day during forty days on bongo board exercise. The emergence of α-wave was indicated a formation of program in central nervous system. The failuer frequency was a result of program on the bongo board exercise. And, EMG was indicated an action of nervous in peripheral system. The results were cleared as follows on skilled process of motor. Phase I (Refractory Period) : The recognition of information at failure is not enough Phase II (Reaction period) : There is a reaction, and it is consciously controled by the leg muscular strenght. Phase III (Formative period : The emergence of α-wave is acknowledged, and a program is forming. Phase IV ( Complete period) : The emergence of α-wave increase rapidly, and EMG discharge is small. Accordingly, it was considered that skilled of motor was a state after Phase III.
