Abstract

A meta-analysis examined data from 36 studies linking physical activity to well-being in older adults without clinical disorders. The weighted mean-change effect size for treatment groups (dC. = 0.24) was almost 3 times the mean for control groups (dC. = 0.09). Aerobic training was most beneficial (dC. = 0.29), and moderate intensity activity was the most beneficial activity level (dC. = 0.34). Longer exercise duration was less beneficial for several types of well-being, though findings are inconclusive. Physical activity had the strongest effects on self-efficacy (dC. =0.38). and improvements in cardiovascular status, strength, and functional capacity were linked to well-being improvement overall. Social-cognitive theory is used to explain the effect of physical activity on well-being.
