| Popis: | 103 The main purpose of this series of studies was to examine the effect of acute, moderate intensity exercise on task-switching in children with attention deficit hyperactivity disorder (ADHD). In study 1, we compared the task-switching performance in children with and without ADHD. Twenty children with ADHD and 20 matched controls performed task-switching while EEG was recorded. Results indicated that children with ADHD demonstrated significantly longer RT and less accuracy compared to controls, especially in mixed condition. ERPs of ADHD participants showed smaller amplitudes and longer latencies of P300 in globe switch effects. In study 2, we further examined the effect of acute bout of aerobic exercise on task switching in children with ADHD. Thirty four children with ADHD performed a task switching paradigm after 30 min of moderate intensity aerobic exercise on a treadmill, and control (seated watching video) sessions, using a within-subjects design during 2 separate, counterbalanced sessions. The results revealed that following a single 30-minute bout of exercise, children with ADHD exhibited smaller global switch cost on RT compared with control session. P300 amplitude increased only following exercise in mixed condition relative to pure condition, whereas no effects were found in the control session. These findings suggest that single bout of moderate intensity aerobic exercise may have positive impacts on working memory in children with ADHD, especially when the task requires greater amounts of executive control. These findings extend the current knowledge by indicating that acute bouts of exercise improve task switching aspect of executive function in children with ADHD. |
