Abstract: Using the exercise and self-esteem model as a guiding framework, this study examined variables related to body image change among 88 overweight and obese women (M age =28.4±7.8; M BMI =31.6±3.5) participating in a 16-week diet and exercise weight-loss intervention. Measures of body image and potential mechanisms of body image change (actual and perceived physical changes, self-efficacy) were administered at baseline, Weeks 8 and 16. Body image improved significantly over the study time-points (ps<.001). Perceived physical changes accounted for most explained variance (12–37%) in body image change (total R 2 =.21–.50). Improved perceptions of body fat were a particularly important predictor in each model (ps≤.04). Results support the notion that to improve body image, perceived changes to the body are more important than actual changes. Such information is integral to developing theories to explain body image change and interventions to maximize it. [Copyright &y& Elsevier]adj =.21–.50).

Abstract: Research examining the impact of physical activity on body image dissatisfaction and physical self-perceptions has been both limited and equivocal. The current research investigated the effects of 6-week aerobic dance on these variables with 50 British schoolgirls aged 13–14 years. A cross-over design was used with two equivalent groups taught normal physical education and aerobic dance in a different order. The Body Attitude Questionnaire (BAQ) and Children and Youth Physical Self-Perception Profile (CY-PSPP) were administered as pre, mid and post-test to each participant in each group before the first intervention, at the change over and after 12 weeks. The results of this study revealed that participation in 6 weeks of aerobic dance significantly reduced body image dissatisfaction (Attractiveness, Feeling Fat, Salience and Strength and Fitness) and enhanced physical self-perceptions (Body Attractiveness and Physical Self-Worth), although these improvements were not sustained. The implications and future research directions are discussed. [Copyright &y& Elsevier]
