The primary purpose of this study was to use meta-analysis to statistically examine the utility of the theory of reasoned action (TRA) and the theory of planned behavior (TPB) for the explanation and prediction of exercise behavior. The results showed that the effect size for the relationships (a) between intention and exercise behavior, attitude and intention, attitude and exercise behavior, perceived behavioral control and intention, and perceived behavioral control and exercise behavior was large; (b) between subjective norm and intention was moderate; and (c) between subjective norm and exercise behavior was zero-order. The results also supported the conclusions that (a) TPB is superior to TRA in accounting for exercise behavior, (b) there is no differences in the ability to predict exercise behavior from proximal and distal measures of intention, and (c) expectation is a better predictor of exercise behavior than intention.
