A Study of Body Sway Mechanism in Standing Posture

为了研究站立姿势下的身体摆动机理，进行了以下实验。利用角镜和激光系统测量人体含糖量是可能的。该系统的标准误差如下。0.0770 mm。对33名男性肯多主义者和36名对照组的重心摆动进行了测量。肯多主义者的重心轨迹长度和面积均小于对照组。为了评估佩戴剑道保护器对平衡能力的影响，参加了男性剑道者和对照组。在佩戴剑道护具的情况下，无论是站立姿势还是“初旦无功夫”姿势，对照组的姿势摆动程度都大于剑道者。

To research the Body sway mechanism in standing posture, following experiments were made.1. It was possible to measure the body swey using by the corner-mirror and laser beam system. Standard error of this system was below. 0.0770mm.2. Sway of the center of gravity was measured to 33 male kendoists and 36 controls using a foce plate system. Length and area of the center of gravity locus in kendoists were smaller than those in controls.3. To assess the effects of wearing kendo protectors on balance ability, male kendoists and controls were participated. With wearing kendo protectors, the degree of postural sway in controls was larger than in kendoists, both in conditions of the standing posture and the posture of "chyudan-no-kamae"
