However, previous studies showed that physical activities had positive impact on cognitive function. Propose: This study examined the effect of exercise on inhibition ability of children with ADHD children, using Event-related potential (ERP) to show activity of brain. Methods: Thirteenparticipants joined in the study and the experimental design used the within-subject design. All participants performed Go/Nogo and Flanker task at three different time points. The interval between each test was eight weeks. Exercise intervention was implemented after the second test, the third task was done after finishing intervention. Results: In behavioral performance, after exercise intervention RT variability reduced and accuracy increased in Flanker task rather than in Go/Nogo task. In ERP, N2 amplitude was larger and latency was shorter after exercise intervention in Flanker task. P3 amplitude decreased and latency was longer in Nogo stimuli of the Go/Nogo task, but not N2. Conclusion: Exercise may improve the inhibition ability, but that would be more attributable to the interference control. However, it still cannot be ruled out history, maturation or repeated testing effects.體適能認知功能ERP抑制能力physical activitycognitive functionERPinhibition
