Lower extremity muscle strength (LEMS) and body balance (BB) are essential for older adults to maintain an upright posture and autonomously perform their basic activities of daily living. This study aimed to examine whether LEMS and BB mediate the relationship between physical activity (PA) and health-related quality of life (HRQoL) in a large sample of community-dwelling older adults. This is a cross-sectional study carried out with 802 individuals, 401 males and 401 females (69.8 ± 5.6 years), residents of the Autonomous Region of Madeira, Portugal. PA and HRQoL were assessed by the Baecke Questionnaire and e SF-36, respectively. LEMS was assessed by the Senior Fitness Test and BB by the Fullerton Advance Balance (FAB). The serial mediation pathway model pointed out that LEMS and BB partially mediated the association between PA and HRQoL in approximately 39.6% and 47%, respectively. The total variance in HRQoL explained by the entire model was 98%. Our findings may indicate the role that LEMS and BB play in the relationship between PA and HRQoL in the older population.
下肢肌肉力量（LEMS）和身体平衡（BB）对于老年人维持直立姿势和自主进行基本日常生活活动至关重要。本研究旨在探讨在大量社区居住的老年人样本中，LEMS和BB是否介导身体活动（PA）与健康相关生活质量（HRQoL）之间的关系。这是一项对802名个体进行的横断面研究，其中401名男性和401名女性（69.8±5.6岁），他们是葡萄牙马德拉自治区的居民。PA和HRQoL分别通过贝克问卷和e SF-36进行评估。LEMS通过高级体能测试进行评估，BB通过富勒顿高级平衡测试（FAB）进行评估。序列中介路径模型指出，LEMS和BB分别在约39.6%和47%的程度上部分介导了PA与HRQoL之间的关联。整个模型解释的HRQoL总方差为98%。我们的研究结果可能表明LEMS和BB在老年人群PA与HRQoL关系中所起的作用。
