Objective：To study the change characteristics of aerobic exercise in obese children before and after comprehensive intervention of frontal lobe and hippocampus region of the brain in the sense of metabolism. Take the event-related potential P300 latency to reflect distribution of obese children with attention, executive function and learning memory, this paper analyzes the effect of comprehensive intervention of aerobic exercise on the frontal lobe and hippocampus of sense in brain metabolism and cognitive function of obese children. Methods：the subject is the primary students from Beijng Golden Lake children＇s summer camp in 2012--2013, with aerobic exercise comprehensive intervention measures on 11 obese children of diet, exercise, education combined intervention therapy, using multidimensional neuropsychologieal tests and com- parative assessment of cognitive function hefore and after the intervention of childhood obesity, the determination of brain hippocampus and frontal lobe of brain metabolic changes of magnetic resonance, event-related potential determination of P300 latency. Result：After aerobic exercise intervention, obese children neuropsychological test indicators of learning memory ability, attention and executive function and language ability were significantly higher （P 〈 0.0 1 ） ; frontal lobe of N-acetyl aspartic acid （NAA）, frontal lobe choline compound （CHO） concentration, temporal leaf N-aeetyl aspartic acid and creatine ratio （NAA/Cr） were compared with those before intervention was significantly increased （P〈0.0 5 ） ;P300 latency significantly shortened. Conclusion：Obesity may affect children＇s brain metabolic processes, and have a negative impact on cognitive function, aerobic exercise intervention to improve cognitive function in obese children with statistical significance, aerobic exercise intervention on cognitive function in children with obesity improvement is mainly through the increase of the frontal lobe of obese children of cerebral metabolism.
