The purpose of this study was to examine the role of body joint motions on postural control during postural sway, the relationship center of foot pressure (CFP) during postural sway and physical fitness, and the effects of an uphill walking on the balancing ability against abrupt acceleration in the elderly.Results were as follows :1) Larger change of angle of hip joint was noted in the elderly compared to the young group. Cross-correlation function between CFP and angle of hip joint in the elderly was relatively kept higher than in the young during postural sway. These results suggest that hip joint motion play the important role of postural control against abrupt acceleration in the elderly.2) Response time and CFP displacement in CFP against abrupt acceleration correlated significantly with strength of planterflexor and dorsiflexor muscles, and knee extensor and flexor muscles, flexibilities of ankle and hip joints, speed of walking as fast as possible.3) The uphill walking group showed significant shorter response times and CFP displacement during postural sway than the control group against abrupt acceleration. There were significant values in leg power, flexibility, agility, reaction time, and static balance in the uphill walking group than in the control group. Total response time in CFP in all subjects correlated significantly with agility, static balance, as well as CFP displacement correlating with leg power and flexibility. These results suggested that the uphill walking would be effective on the balancing ability against abrupt acceleration in the elderly.

本研究旨在探讨身体关节运动对老年人摇摆时姿势控制的影响、摇摆时足底压力中心（CFP）与身体素质的关系，以及上坡步行对老年人抵抗突然加速度平衡能力的影响。姿势摆动过程中，老年人CFP与髋关节角度的相关函数相对保持高于青年人。2）CFP对突然加速度的反应时间和CFP位移与跖屈肌、背屈肌、膝伸肌、膝屈肌的力量、踝关节和髋关节的灵活性、3）上坡步行组在姿势摆动时的反应时间和CFP位移均明显短于对照组。上坡步行组的腿部力量、柔韧性、敏捷性、反应时间和静态平衡能力均显著高于对照组。所有受试者的CFP总反应时间与敏捷性、静态平衡以及与腿部力量和柔韧性相关的CFP位移显著相关。这些结果表明，上坡步行将是有效的平衡能力，对突然加速的老年人。
