Measurements of EEGs and other physiological changes while practicing Taichi-quan were followed up from our last JISLIS report. In these measurements, we studied responses of a female beginner who did Taichi-quan training for a 6-month period. Her EGG and other measurements were compared with those of two experts who have been training for 12 and 20 years. As a comparison for the benefits of Taichi-quan exercise, a simple stepping was carried out. The EEG waves, which are usually large in the occipital area, become smaller during Taichi-quan, because of movement. However, the waves of advanced trainees decreased only a little and the ratios of the frontal to the occipital waves, [Fp]/[O], became large. The beginner in this report could practice Taichi-quan in a more relaxed manner as the length of the training period became longer and her waves became gradually larger. In the same time, the frontal ? waves also became larger and the ratio [Fp]/[O] tended to become slightly larger with each additional training month. In the resting state after the comparison stepping exercise, the awakened level of the subjects tended to become lower, though that after Taichi-quan the level was kept very well.
