Abstract

Introduction: This study investigates the acute effects of high-intensity interval exercise on brain activity in preschool children, focusing on changes in electroencephalogram (EEG) bands before, immediately after, and 20 min post-exercise.

Methods: Eleven children (5-6 years) participated, but EEG recordings were included only if all channels maintained a quality score >3 (0-4 scale updated every 0.5 s), resulting in the exclusion of two participants due to insufficient high-quality data.

Results: EEG data revealing significant increases in Theta, Alpha1, and Alpha2 bands, suggesting enhanced relaxation, attentiveness, and readiness to learn. Conversely, Beta and Gamma bands showed reductions, especially in frontal, temporal, and parietal regions, indicating decreased stress and mental effort.

Discussion: These effects persisted for up to 20 min after exercise, suggesting that brief, high-intensity exercise induces EEG changes associated with states of attentional readiness and emotional regulation, which may support learning, pending further validation.

学龄前儿童主动休息后大脑皮层活动的变化:MOVI-HIIT研究。
前言:本研究探讨了高强度间歇运动对学龄前儿童脑活动的急性影响,重点关注运动前、运动后和运动后20分钟脑电图(EEG)带的变化。方法:11名儿童(5-6岁)参与,但只有在所有通道保持质量评分>.3(0-4评分每0.5 s更新一次)的情况下才纳入EEG记录,由于高质量数据不足导致2名参与者被排除。结果:脑电图数据显示Theta、Alpha1和Alpha2波段显著增加,表明放松、注意力和学习准备增强。相反,β和γ波段显示减少,特别是在额叶、颞叶和顶叶区域,表明压力和精神努力减少。讨论:这些影响在运动后持续20分钟,表明短暂的高强度运动诱导与注意力准备状态和情绪调节相关的脑电图变化,这可能支持学习,有待进一步验证。
