Objectives

To examine the effect of acute exercise on multiple ERP components in young adults and to determine whether acute moderate-intensity exercise exerts a general or selective effect on a cognitive task requiring basic information processing and the inhibitory aspect of executive function.

Design

A randomized controlled trial design.

Methods

Forty young adults were randomly assigned to one of two experimental groups: (a) an acute bout of moderate-intensity exercise (n = 20) or (b) a non-exercise control (n = 20). The participants completed congruent and incongruent trials of a flanker task at baseline and after the treatments (exercise or control) while event-related potentials (ERPs) were recorded.

Results

Acute moderate-intensity exercise facilitated response times for both congruent and incongruent flanker conditions. Larger P2, N2c, and P3 amplitudes were observed under both conditions following the exercise. No effects on accuracy or latency were found.

Conclusion

These findings suggest that acute moderate-intensity exercise generally influences basic information processing and the inhibitory aspect of executive function in healthy young adults. The ERP data imply that general facilitation occurs in the perceptual, stimulus classification and evaluation processes.

急性中等强度运动通常会增强与知觉和认知过程有关的神经资源：一项随机对照ERP研究

目标

若要检查急性运动对年轻人中多个ERP成分的影响，并确定急性中等强度运动是否对需要基本信息处理和执行功能抑制方面的认知任务产生一般或选择性影响。

设计

随机对照试验设计。

方法

40名年轻成年人被随机分配到两个实验组之一：（a）中强度运动的急性发作（n  = 20）或（b）非运动对照（n  = 20）。在记录事件相关电位（ERP）的同时，参与者在基线和治疗（锻炼或对照）后完成了侧翼任务的全等和不一致试验。

结果

急性中等强度运动可促进全副和全副侧卫条件下的响应时间。运动后在两种情况下均观察到较大的P2，N2c和P3振幅。没有发现对准确性或延迟的影响。

结论

这些发现表明，在健康的年轻人中，急性中等强度的锻炼通常会影响基本信息处理和执行功能的抑制作用。ERP数据暗示在感知，刺激分类和评估过程中发生了一般的促进。
