N2  - The present study was designed to examine the effects of aerobic exercise on the change of alpha wave component in electroencephalogram (EEG) and plasma beta-endorphin. Exercise consisted of 30-min cycling on an ergometer with the load adjusted to elicit a heart rate rise of 50% between resting and predicted maximal value. The EEG signals and blood samples were obtained before and after 30-min exercise. The EEG signal was digitized at a sampling frequency of 64 Hz and analyzed by means of computer-aided decomposition algorithm and frequency power spectral analyses, respectively. The blood samples were immediately centrifuged for 15-min for quantitative analysis of beta-endorphin by means of radioimmunoassay method. Results indicated that beta-endorphin was significantly greater after exercise as compared to that of the resting control. It was also found that the larger the changes in beta-endorphin following exercise, the higher the appearance rate of alpha wave in EEG. There was a positive and significant correlation (r=.563, p<0.05) between the increase in alpha wave component and that of the plasma beta-endorphin. These results suggest that tranquilizer effects of aerobic exercise could be explained, at least in part, by the increase of alpha wave component and plasma beta-endorphin which in turn bring about the relaxation effects upon the central nervous system.
