认知和ERP评估后进行运动和静坐休息。根据基线抑制对照性能将样品分为两组。对于表现较低的人，观察到准确性和P3振幅的选择性增加。观察运动后P3潜伏期和N2波幅的变化。本研究探讨了中等强度的有氧运动对两组儿童认知控制方面的影响，这两组儿童分为高任务和低任务的表现。40名青春期前儿童在不同场合进行20分钟的跑步机行走和坐位休息后，在改良的侧翼任务中收集事件相关脑电位（ERPs）。根据休息后的任务表现，参与者被分为两组。研究结果显示，运动后，高性能保持准确性，并表现出P3振幅没有变化相比，坐着休息。低性能表现出差异效应，如准确性措施的改善，P3振幅增加后的运动。最后，两组都显示较小的N2振幅和较短的P3潜伏期运动后，这表明在反应冲突和刺激分类的速度的整体促进。目前的研究结果重复了先前的研究报告，即急性有氧运动对儿童认知能力的有益影响。然而，抑制控制能力较低的儿童可能从单次运动中获益最多。这些数据是第一批证明身体活动对抑制控制不同的个体的不同影响的数据之一，并进一步支持有氧运动在发育过程中对大脑健康的作用。
Cognitive and ERP assessments were performed following exercise and seated rest. The sample was bifurcated according to baseline inhibitory control performance. Selective increases in accuracy and P3 amplitude were observed for lower-performers. Generalized P3 latency and N2 amplitude changes were observed after exercise. The present study examined the effects of moderate-intensity aerobic exercise on aspects of cognitive control in two groups of children categorized by higher- and lower-task performance. Event-related brain potentials (ERPs) were collected in 40 preadolescent children during a modified flanker task following 20 min of treadmill walking and seated rest on separate occasions. Participants were bifurcated into two groups based on task performance following the resting session. Findings revealed that following exercise, higher-performers maintained accuracy and exhibited no change in P3 amplitude compared to seated rest. Lower-performers demonstrated a differential effect, such that accuracy measures improved, and P3 amplitude increased following exercise. Lastly, both groups displayed smaller N2 amplitude and shorter P3 latency following exercise, suggesting an overall facilitation in response conflict and the speed of stimulus classification. The current findings replicate prior research reporting the beneficial influence of acute aerobic exercise on cognitive performance in children. However, children with lower inhibitory control capacity may benefit the most from single bouts of exercise. These data are among the first to demonstrate the differential effect of physical activity on individuals who vary in inhibitory control, and further support the role of aerobic exercise for brain health during development.
