Effects of exercise interventions on body image: a meta-analysis.

Our meta-analysis examined the impact of exercise interventions on body image; and participant, intervention, and design features associated with larger effects. We identified 57 interventions (with pre-and post-data for the exercise and control groups) examining the effects of exercise on body image. A small random effect indicated that exercise intervention conditions had improved body image compared to control conditions; and that participant (age), design (year of publication), and intervention (exercise frequency and specificity) features moderated the effect size. Research examining the mechanisms and the exercise dose-response required for body image change is needed.
