Changes in EEG, ECG and respiration were studied with qigong trainees through experiments every three months for one year. The subjects were two Japanese males and two females who were usually training in a kind of dynamic qigong. Alpha waves on the occipital region, which is an indicator of relaxation, tended to become large in the course of the year's training. The ratio of the alpha amplitude on the frontal region to the occipital region seemed to become larger during qigong, however, the changes in the ratio with more training were not so remarkable. The frequency of the alpha waves become slower during quiet qigong and faster during dynamic qigong, though, its change during one year was not clear. The heart rate increased even during quiet qigong compared the resting state. Its increasing rate became smaller with subjects' training length.
