The characteristics and theoretical basis of the Qigong maneuver.

We have made a systematic experimental study since we proposed the Qigong (Q-G) maneuver in 1986. The purpose of this article is to summarize our 5-year research project. It describes the theoretical problems of the Q-G maneuver, including the mechanism of blood pressure elevation induced by the Q-G maneuver, analysis of the maneuver elements and their respective contribution, the theory and method of muscular contraction in the Q-G maneuver, and the theory and practice of seated posture in the anti-G maneuver. We also describe the characteristics of the Q-G maneuver in five aspects.
