要旨: 本研究は、少林内功試行時における生理的反応を明らかにするため、近赤外線分光法(NIRS)を用いて脳酸素代謝動態を分析した。被検者は、少林内功の修練年数40年以上の経験を持つ55歳の男性1名である。椅座位安静時の平均酸素飽和度(StO2)は79.6%、少林内功試行時ではおよそ77~79%の範囲内であった。椅座位安静時の平均総ヘモグロビン(TotalHb)量は393.0cm・g/l、少林内功時では390~396cm・g/lの範囲内であった。椅座位安静時の酸素化ヘモグロビン(OxyHb)量は312.9cm・g/l、少林内功時では299~312cm・g/lの範囲内であり、いずれも椅座位安静時と少林内功時で有意な差は認められなかった。以上の結果から、少林内功熟練者は、自然呼吸により常に安定した脳内の血中酸素濃度や血液中のヘモグロビン濃度を維持し、脳内における経済的な酸素消費を促し、血中脱酸素化ヘモグロビン(DeoxyHb) 量の増加を抑制することが可能とするものであると推察される。

【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
