A cross-sectional survey was done to investigate the pathways the physical activity acts in improving physical fitness and functional outcomes of older adults (60 years and above) using 880 community-dwelling older adults in Sri Lanka. Structural Equation Modeling (SEM) was used. The final SEM model included five latent factors and 14 co-variances. Goodness of Fit Index (GFI), Comparative fit index (CFI) and Root Mean Square Error of Approximation (RMSEA) values of the model were 0.95, 0.93, 0.91, and 0.05 respectively, indicating a good model fit. Strength enhances balance (β = .52, < .01) and reduces the time required to complete physical functions (β = -.65, < .01). Since strength declines with advancing age, muscle-strengthening activity programs should be promoted to enhance balance and functional performances in older adults in advanced ages. Strength test (hand grip and leg strength) can be used as a screening test to predict potential risk of falls and functional disabilities in older adults.
我们开展了一项横断面调查，以研究身体活动对斯里兰卡880名60岁及以上社区居住老年人身体素质和功能结局的改善途径。我们采用了结构方程模型（SEM）。最终的SEM模型包括五个潜在因素和14个协方差。该模型的拟合优度指数（GFI）、比较拟合指数（CFI）和近似均方根误差（RMSEA）值分别为0.95、0.93、0.91和0.05，表明模型拟合良好。力量增强平衡（β = 0.52，p < 0.01）并减少完成身体功能所需的时间（β = -0.65，p < 0.01）。由于力量会随着年龄增长而下降，因此应推广肌肉强化活动计划，以增强高龄老年人的平衡能力和功能表现。力量测试（握力和腿部力量）可作为一项筛查测试，用于预测老年人跌倒和功能残疾的潜在风险。
