For analyzing the qigong mechanism, it is a quite important to measure the master's physiological changes before and during qigong, such as brain-wave, blood pressure, heart rate, breathing, and skin temperature. At external qigong practice, we also detected some kind of signal in a far-infrared ray region from the center of his palm of the right hand. In these experiments, we examined two Chinese qigong masters and one Japanese.
In the static qigong case, alpha brain waves were superior to beta brain waves. Especially, there was a place which showed extremely high potential alpha1 brain waves in their right frontal lobe. Also, their blood pressure, heart rate and surface temperature increased. These phenomena are due to controlling their autonomic nervous system, especially their sympathetic nerves.
In the case of external qigong, it was found that the potential alpha brain waves and beta waves were superior in the right side of their brains, the same as in the internal qigong case. There was also a high potential region in their right frontal lobe. In these cases, their blood pressure and heart rate increased comparable to the control period. To analyze these phenomena, we measured his breathing rate, which increased about 2.5 times. Especially after a breathing through his nose, they breathed out several times using a special breathing technique. By this means also, they control their sympathetic nerves and in some cases, they also controlled their para-sympathetic nerves. Therefore, we found a close relationship between breathing and the activity of the brain in the qigong. Also in the experiment to detect the intensity of far-infrared rays from the center of his palm (ROKYU-acpuncture spot), we detect about 1 Hz moduration signal. In this modulation period, the master's blood pressure, heart rate and breathing increased.
