Abstract Objective To determine the effect of exercise intervention on Chinese overweight children’s attraction to physical activity，physical self-perception and body satisfaction. Methods A cross sectional study of Chinese overweight school children completed questionnaires related to physical activity attitude，physical self-concept，and body satisfaction. One hundred Chinese overweight children（34% girls and 66% boys）aged 8 - 12 years were selected from a primary school in Hong Kong，China. Overweight children were defined and identified using the international cut-off points by sex between 2 and 18 years old of the age-related body mass index（BMI）of 25 kg/m2. Weight and height of participants were measured in school physical education class and BMI was calculated. Physical activity attitude was measured by the Children’s Attraction to Physical Activity（CAPA）. Physical self-concept was measured using the Physical Self-Perception Profile for Children（C-PSPP）. Body satisfac-tion was established using the silhouette matching task（SMT）. Results Significant intervention effect was found in C-PSPP. Repeated measures ANOVA demonstrated that the intervention was significant in improving strength subscale，physical self-worth，and global self-worth. Regarding CAPA，and SMT，all factors were not significant. Polynomial regression analyses indicated that there is a clear nonlinear relationship on the sport competence and body attractiveness subscales. Conclusion The intervention program can improve the physical self worth，global self worth and certain physical self-perception subscales of the overweight Chinese children，especially for the children who have lower scores in sport competence and body attractiveness.
