The Physiological Study of Ki in Ki Aikido (II)

As a way to study Ki in Ki Aikido, an experiment on the unbendable arm was carried out, where physiological measurements were made to confirm that Ki is not a physical power. Through analysis of the data collected , it could be concluded that even in the state of extending Ki, about half of the sympathetic nerve system was activated compared with the state of relying only on the physical power. It was also seen that exhalation was critical when the arm was unbendable, suggesting it relates to Ki strength, which is complementely different from the physical power force in stoppingb respiration.
