Abstract:
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, p<.01) and reduces the time required to complete physical functions (β=−.65, p<.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.
