Abstract
Decline on posture control and depend on visual information, which according to the System Model is due to effects of decline on posture control. Although effects of physical activity on posture control were attested. The purpose of this study was to investigate effects of physical activity and visual information on posture control, and further, investigate the effects of physical activity on visual dependant. A survey with Physical activity Scale for the Elderly (PASE) was administered to 40 older adults (mean age = 70.5 yrs., SD = 3.9 yrs.). The experimental task was to stand on two-legs for eyes-opened and eyes-closed conditions. The area of press of center (COP) was recorded by Castsys 2000 Sway Force Plate system. Mixed-design two-way ANOVA (physical activity level × visual information) with repeated measures on visual information, revealed that (1) Interaction effects were found during acquisition in different physical activity level and visual information (F(1,38) = 6.03, p < .05, ES = .13, power = .66), and significant different was found in eye-closed condition (F (1,38) = 17.38, p < .05, ES = .64); (2) The visual dependant in posture control, high physical activity group and low physical activity group was significant different (F (1,38) = 7.50, p < .05, ES = .33)。It was concluded that (1) the effect of physical activity and visual information on posture control, (2) in posture control, the visual dependant in older adults of high physical activity was low than older adults of low physical activity.
Key words：older adults, physical activity, visual information, postural control, balance
