Studies of qigong effect on the human body [via] macro and micro circulatory parameters measurement

Qigong, an ancient Chinese art of exercise for protecting and strengthening health, is very effective in treatment of many diseases. But the mechanism of its efficacy is not clear yet. During the qigong test, the computerized synchronous system for macro- and microcirculatory parameters measurement was used to check the heart rate (HR), respiration (RESP) . body temperature (BY), electrocardiogram (ECG) . carotid arterial pulse (CAP), photoelectric plethysmogram (PEPS), skin microcirculatory blood flow (SMBF), blood pressure (BP), and the nail-fold microcirculation (NFM).

The SMBF of the qigong master himself was tested at yuji (L 10) before, after and during the qigong exercise. Tests were done in 5 qigong healthy recipients (males and females), 26 to 50 years by age.

Of the parameters measured, the most significant effect of qigong was on the SMBF measured by a laser Doppler flowmeter. The results showed marked effects in amplitude of SMBF both of the qigong master and recipients (See Table l) . All other parameters showed detectable changes during the qigong test, but not enough to be statistically significant. This
elucidates that qigong is very effective on the increase of the peripheral blood flow volume, thus enhancing the microvascular vasomotion. The investigation is continuing.
