EFFECTS OF EXERCISE TRAINING ON ANXIETY - A METAANALYSIS

A meta-analysis was conducted on 40 studies (76 effects) in order to examine exercise training as a method of stress-management treatment for adults It offered evidence of a low-to-moderate positive effect in anxiety reduction. Exercise training studies that examined change from pre- to post-treatment and studies that examined both change over time and between group differences were examined separately. The unbiased weighted average effect sizes were .45 and .36, respectively. Thus, exercise training improved anxiety levels an average of .36 standard deviations over alternative or control conditions. Adults who were more likely to have a stressful lifestyle benefited more from the exercise training than those who did not. Recommendations are made for both practice and research.
