To investigate cognitive flexibility and task-related heart rate variability following moderately intense aerobic exercise and after watching a video in both children with ADHD and healthy controls. Using a cross-over design, participants completed cognitive assessments following exercise and a physically inactive control condition. Behavioral performance was assessed using the Alternate Uses task. Heart rate variability was recorded via electrocardiography during the cognitive task. The statistical analysis revealed that in comparison with the control condition, both groups showed higher cognitive flexibility following aerobic exercise. Moreover, decreased low frequency and high frequency power was observed in the exercise condition. The findings suggest that exercise elicits similar benefits for cognitive flexibility in children with ADHD and healthy controls, partly due to an increase in arousal induced by parasympathetic withdrawal.
研究中，采用交叉设计，让患有注意缺陷多动障碍（ADHD）的儿童和健康对照者在进行中等强度有氧运动和观看视频后，分别完成认知评估。使用交替用途任务评估行为表现，通过心电图记录认知任务过程中心率变异性。统计分析表明，与对照条件相比，两组在有氧运动后认知灵活性均有所提高。此外，运动条件下低频和高频功率降低。研究结果表明，运动对 ADHD 儿童和健康对照者的认知灵活性均具有相似的益处，这部分归因于副交感神经撤出引起的唤醒增加。
