This review applied meta-analytic procedures to integrate research findings examining the impact of exercise on body image. We performed extensive literature searching strategies and located 121 published and unpublished studies that examined the impact of exercise on body image. Primary study results were coded, and meta-analytic procedures were conducted. Studies were grouped into intervention (i.e., exercise vs nonexercise group post-exercise intervention body-image scores), single group (i.e., pre vs post exercise intervention body-image scores), and correlational (i.e., exercisers vs nonexercisers body-image scores) effect sizes. Small effect sizes (that were weighted by sample size), that were significantly different from zero, indicated that: (a) exercisers had a more positive body image than nonexercisers; (b) exercise intervention participants reported a more positive body image post intervention compared to the nonexercising control participants; and (c) exercisers had a significant improvement in body image scores following an exercise intervention. We concluded that exercise was associated with improved body image. Moderating variables and implications for exercise prescription to improve body image were discussed.
