本研究探讨了课间运动干预对事件相关电位P300成分和抑制控制的影响。年龄在12-15岁的青少年被分配到运动和控制组。运动组每天进行20 min的有氧运动和协调性运动，持续8周。在干预前后，使用脑电图记录Stroop任务期间的刺激锁定事件相关电位。基于神经元的排列测试显示，与对照组相比，运动中P300振幅的增加更大，顶枕区最明显。此外，P300振幅的增加与Stroop任务上不相容反应时间的减少相关。在学校休息时间实施的锻炼计划增强了青少年的抑制控制。这种好处似乎是由于对认知任务的注意力资源的分配得到了改善。
The present study investigated the effects of an exercise intervention, which was implemented during school-break time, on the P300 component of event-related potentials and inhibitory control. Adolescents aged 12-15 years were allocated to an exercise and control group. The exercise group performed 20 min of aerobic and coordinative exercise per school day over a period of 8 weeks. Before and after the intervention, stimulus-locked event-related potentials were recorded during a Stroop task using electroencephalography. Cluster-based permutation testing revealed a greater increase of the P300 amplitude in the exercise compared to the control group, most pronounced for the parieto-occipital region. Additionally, increases in P300 amplitude were associated with decreases in incompatible reaction time on the Stroop task. An exercise program implemented during school-break time enhances adolescents' inhibitory control. This benefit seems to be due to an improved allocation of attentional resources towards the cognitive task.
