Background

Frontal alpha asymmetry (FAA) has been associated with the regulation of certain types of internalizing psychopathologies, and is affected by acute aerobic exercise (AE). However, no previous studies have examined the association between FAA and internalizing problems or the effects of acute exercise on FAA in children with ADHD.

Aims

This study had two objectives. First, it aimed to examine the relationship between FAA and internalizing behaviors in children with ADHD. Second, it sought to investigate the differential effects of acute AE (30 and 50 min) on FAA.

Method

Participants were assigned to one of the following three groups: 50 min of AE, 30 min of AE, and a control group. Resting electroencephalogram (EEG) data were recorded before and after their respective treatments. EEG data from 43 participants were analyzed to investigate the association between pre-test FAA and internalizing problems as assessed by Child Behavior Checklist scores. Additionally, EEG data from 46 participants were analyzed to examine the effects of acute AE on post-test FAA while controlling for pre-test FAA.

Results

Pre-test FAA was found to be significantly negatively associated with internalizing problems, with both hemispheres contributing to this association. Regarding the effects of acute exercise, the 50-minute AE group had highest post-test FAA, reflected by the increased relative left-side frontal activity.

Conclusions

These findings suggest that FAA is a biological marker of internalizing symptoms in children with ADHD, and a 50-minute session of AE can effectively modulate FAA.

注意缺陷/多动障碍儿童内化问题与急性运动持续时间的关系：额叶α不对称的作用

背景

额叶 α 不对称 (FAA) 与某些类型的内化精神病理学的调节有关，并受急性有氧运动 (AE) 的影响。然而，以前没有研究检查过 FAA 与内化问题之间的关联，或急性运动对 ADHD 儿童的 FAA 的影响。

宗旨

这项研究有两个目标。首先，它旨在检查 FAA 与 ADHD 儿童内化行为之间的关系。其次，它试图研究急性 AE（30 和 50 分钟）对 FAA 的不同影响。

方法

参与者被分配到以下三组之一：50 分钟的 AE、30 分钟的 AE 和一个对照组。在各自的治疗前后记录静息脑电图（EEG）数据。分析了来自 43 名参与者的 EEG 数据，以调查测试前 FAA 与通过儿童行为清单评分评估的内化问题之间的关联。此外，还分析了 46 名参与者的 EEG 数据，以检查急性 AE 对测试后 FAA 的影响，同时控制测试前 FAA。

结果

测试前 FAA 被发现与内化问题显着负相关，两个半球都有助于这种关联。关于急性运动的影响，50 分钟 AE 组的测试后 FAA 最高，表现为相对左侧额叶活动增加。

结论

这些发现表明 FAA 是 ADHD 儿童内化症状的生物标志物，50 分钟的 AE 可以有效调节 FAA。
