PURPOSE: To identify the effects of adiposity and a physical activity (PA) intervention on cognitive neuroelectric indices inhibitory control in preadolescent children. METHODS: Children were randomly assigned to either 9-month afterschool or wait-list (CON) group. completed task that manipulated at pre- post-test while measures performance P3-event related potential (ERP) assessed. further grouped according weight category. 76 children with obesity (39 PA; 37 CON) testing. A sample normal (NW) (n=76) matched based treatment allocation demographic variables age, sex, IQ, SES, fat-free VO2max. Changes included whole body percent fat (%Fat), subcutaneous abdominal adipose tissue (SAAT), visceral (VAT). The influence brain function was examined. RESULTS: PA group decreased %Fat from (p=.011); an effect not observed CON gained SAAT VAT (p's≤0.001), whereas did not. showed larger P3 amplitude (p=.026); seen differ between groups pre-test for obesity; however, demonstrated compared (p=.006). had smaller (p=.003), NW Results suggest physically inactive have increased over 9 months. Furthermore, results may be particularly beneficial obesity, as they post-test. CONCLUSION: is pre-adolescent children, especially those obesity. Given childhood public health concern array complications, these important implications
