The Physiological Study of Ki in Ki Aikido (1)

Ki Aikido is a Japanese material art to arm oneself against attack from others, in which respiration techniques play a visual role. Ki Aikido was established by Mr.Koichi Tohei, through examining every movement of Aikido transmitted by Mr.Morihei Ueshiba. The physiological effect was studied by comparing breathing conducted by two examinees, a beginner and a distinguished master of Ki Aikido. Ki in Ki Aikido could be physiologically understood through the respiration especially ECG,EEG, blood pressure. In the case of the beginner, the sympathetic nervous system, was lower at Ki respiration period compared to the activity at the closed eyes and relax period. But the activity at the closed eyes and relaxed period exhalation through the mouth, makes an increase of alpha wave level and expansion of alpha wave in his topograph compared to exhalation through the nose.
