Abstract

The purpose of this study is to observe the relationships between aspects of brain wave and skill levels during the second service motions on tennis. Three inter collegiate players were grouped as the skilled subjects, four regional college tournament players were grouped as the intermediated subjects and three loser at qualify in the regional college tournament players were grouped as the unskilled subjects were participated in this study. Brain wave during open or close eye at sitting position, fatigue test for simple numeric calculation, imaging for service motion, to sing a song and to talk about their lovers were recorded as the basic pre-tests in a experimental room. The second serve were done in following conditions: (1) Only second service activities, (2) On the situation in the opponent's match point, (3) With the penalty physical exercise if they lose their points or more penalty physical exercise if their serve are fault. By using Fast Fourier Transform (FFT), Power spectrum were calculated to get the activity levels of brain. Higher voltage of brain wave were observed in the situation of singing a song and talking about their lovers than other situations in pre-test. However individual scattering were existed in two subjects. It suggests the difficulty of making the situation for mental tension. Lower voltage of beta wave were recorded by skilled subjects in all of their conditions. It shows that they keep mental equilibrium. Voltage of intermediated subjects were increased with severe conditions. It means that they get frightened in the important match. Higher voltage were always recorded by unskilled subjects. It suggests that they did not pay any attention to the aspect of game but their own motions.
