Relations of Body Concerns and Exercise Behavior: A Meta-Analysis

Numerous studies have examined the relations between body concerns and exercise. This meta-analysis is based on 35 studies with exercise programs influencing body concerns. There was an overall effect of .45, suggesting that exercise positively affects body concerns. Moderator variables, such as sex, type of exercise, and length of intervention were examined and discussed. Generally, there were no sex differences in effects of exercise on body concerns, but anaerobic exercise such as weight training generated a stronger effect (d= .64) than aerobic-type exercises such as jogging (d= .40).
