Measurements of Physiological Effects of Internal Qigong; The Six-Word Practice (Rokujiketsu)

There are many types of internal qigong, but there are very few that incorporate vocalization. We looked at the six-word practice with vocalizaion in qigong and report the analysis of the physiological data we measured. We found that sympathetic nervous system in the autonomic nervous system are affected powerfully by comparing results for the six-word practice with a standing posture qigong exercise. In the six-word practice, the carotid artery and the nearby blood flow increased right after vocalization. The flow rate of blood in the heart, liver and kidney increased as was seen by ultrasound imaging. We also found that vocalization during qigong influenced physiological data further. After vocalizations, the alpha waves increased in the head of the master and the qigong was effective for relaxation.
