: This study investigates the relationship between lower limb strength and postural stability in single-leg stance using the Balance Master system. : The research involved 64 participants divided into sedentary and physically active groups based on metabolic equivalents of task (METs) values, normal weight, overweight, and obese according to body composition. Postural control was evaluated using the Sensory Organization Test. : The results showed that there were no significant differences in mean and maximum lower limb strength between the groups. Furthermore, postural stability in open and closed eyes conditions did not show significant differences between the groups. However, a significant positive correlation was observed between lower limb strength and stability in single-leg stance with eyes open. : These findings suggest that lower limb muscle strength is essential for postural stability, especially when vision is available to aid balance. The study highlights the importance of interventions focused on strengthening muscles to improve physical functionality in adults.
本研究使用平衡大师系统调查单腿站立时下肢力量与姿势稳定性之间的关系。该研究涉及64名参与者，根据任务代谢当量（METs）值分为久坐组和体力活动组，并根据身体成分分为正常体重、超重和肥胖组。使用感觉组织测试评估姿势控制。结果表明，各组之间的平均和最大下肢力量没有显著差异。此外，睁眼和闭眼条件下的姿势稳定性在各组之间也没有显著差异。然而，观察到睁眼单腿站立时下肢力量与稳定性之间存在显著正相关。这些发现表明，下肢肌肉力量对于姿势稳定性至关重要，尤其是在视觉可辅助平衡时。该研究强调了专注于增强肌肉以改善成年人身体功能的干预措施的重要性。
