• Description of studies
• The overall M random effect size (ES) of 0.29 (SE = .04, CI = +.07; Q(97) = 207.03; I2 = 52.66) was small and revealed that exercise resulted in improved body image from pre- to post-intervention for the intervention group compared to a control group. A total of 57 publications (M study year =
• 1997, range = 1972–2007) with 98 separate com- parisons were included in our meta-analysis (a list of excluded studies is available from the first author). Reasons for more than one effect size per study were that studies reported results separate by age (n = 6) and/or gender (n = 2), and studies with either multiple control groups (n = 7) or exercise groups (n = 15).
