Postural balance is an essential part of a wide range of activities, from daily living tasks to sports. Regularly repeated physical and/or sport activities improve both the postural performance and the postural strategy. The aim of our study was to evaluate if the physical activity level is a factor that influences postural balance performance, including the impact of vision and gender, in healthy young adults. Postural balance was assessed in 78 subjects (38 males and 40 females, aged 20.64 ± 1.18 years) by using the PoData system, in open (EO) and closed (EC) eye conditions. Based on the physical activity level, subjects were classified in two groups-low physical activity level ( = 36, 46.15%) and moderate physical activity level ( = 42, 53.85%). A group significant difference was found only for the average centre of pressure (CoP) deviations on the latero-lateral axis (CoP), with a higher lateral deviation of the CoP (toward right) in the low physical activity group (F = 4.005, = 0.04). CoP path length, the 90% confidence ellipse and maximum CoP speed were significantly increased in EC conditions. A statistically significant interaction effect (vision × physical activity) was observed for the CoP path length (F = 7.9, = 0.006).
姿势平衡是广泛活动的重要组成部分，从日常生活任务到运动。定期重复的身体和/或运动活动可以改善姿势表现和姿势策略。我们的研究目的是评估身体活动水平是否是影响姿势平衡表现的因素，包括视觉和性别因素，在健康的年轻成年人中。使用 PoData 系统评估了 78 名受试者（38 名男性和 40 名女性，年龄 20.64 ± 1.18 岁）的姿势平衡，分别在睁眼（EO）和闭眼（EC）条件下进行。根据身体活动水平，将受试者分为两组：低身体活动水平（ = 36，46.15%）和中身体活动水平（ = 42，53.85%）。仅在平均压力中心（CoP）侧向偏差（CoP）上发现了组间差异，低身体活动组的 CoP 侧向偏差（向右侧）更高（F = 4.005， = 0.04）。在 EC 条件下，CoP 路径长度、90%置信椭圆和最大 CoP 速度显著增加。CoP 路径长度的观察到统计学上显著的交互效应（视觉×身体活动）（F = 7.9， = 0.006）。
