【Abstract】
The body is continuously moved while maintaining a posture of being bent forward a little. Movement is also assisted by breathing whilst practicing the uprighting posture of Shaolin Internal Qigong. It is assumed that the uprighting posture of Shaolin Internal Qigong differs from the general standing posture. The posture control mechanism always works when the body is active so that body sway is well controlled in the upright position.
In this study, we investigated various factors of body sway of a skilled Shaolin Internal Qigong doctor. In standing posture at rest, body sway was observed to converge at a fixed range. The fixed range began to diverge and traces of body sway showed when the anteroposterior direction was dominant when engaging in the uprighting posture. Each value of length (LNG), LNG/TIME and envelope area (ENV/AREA) visibly and clearly increased in the uprighting posture. Comparing position vector of standing posture in rest with that of the uprighting posture, the latter showed a distinct tendency for both the body to sway and incline to the axis of the participant’s foot. Uprighting posture is achieved by standing with both toes pointed inward and apart approximating a “distance near to shoulder width”. In the astride posture, base of support widened so that body stability in the lateral direction increased.
In addition, body stability should increase in the anteroposterior direction while arms extend straight out from the body, because the base of support was widened. But results showed that each value of body sway of the uprighting posture was clearer than each of the non uprighting posture.
The reasons seem to relate to the three following factors:

(1) breath during activity ;

(2) maintaining contraction of both the upper extremity muscles and the antigravity muscles ;

(3) regulating consciousness in the uprighting posture. An instructor should pay more attention to a beginner with the disorder of labyrinthine sense organ system and to an on old person to prevent falls that usually occur during training.

Key Words: Shaolin Internal Qigong, uprighting posture, body sway, posture control mechanism, fall of old person
