摘要
目的:探讨不同认知参与的急性跑步对儿童抑制控制功能、情绪及前额叶激活的影响,以及情绪在运动干预对抑制控制影响中的中介作用。方法:以90名小学四年级儿童为研究对象,随机分为认知跑步组(n=30),传统跑步组(n=30)及对照组(n=30),分别进行20 min中等强度认知参与跑步、传统跑步或休息。采用Go/No-go范式认知任务和功能性近红外光谱技术(functional near-infrared spectroscopy,fNIRS)考察运动干预前、后15 min儿童抑制控制功能和前额叶脑区激活的变化;采用二维情绪量表(Two-Dimensional Mood Scale,TDMS)测量儿童在运动干预前、后的情绪变化。结果:1)在传统跑步和认知参与跑步后,儿童在Go/No-go认知任务中go trail的反应时均显著缩短(P<0.01),而认知参与跑显著提高了nogo trail的正确率(P<0.01);2)与传统跑步相比,认知参与跑步更有效地提升了儿童情绪的愉悦水平和唤醒水平(P<0.05),并显著提高了左背外侧前额叶的氧合血红蛋白(oxyhemoglobin,Oxy-Hb)浓度(P<0.01);3)左背外侧前额叶Oxy-Hb浓度的增加量与唤醒水平的增加量显著正相关(r=0.31,P<0.01),与反应时的增加量显著负相关(r=-0.22,P<0.05);4)情绪的唤醒水平在运动干预与抑制控制反应时之间起遮掩效应。结论:认知参与运动可以更有效改善儿童情绪,增强抑制控制功能,其神经机制可能是通过激活与情绪反应相关的左背外侧前额叶,进而增强儿童的抑制控制功能,而运动诱发的情绪唤醒水平在运动干预对抑制控制影响中表现为遮掩效应。
Objective:To explore the effects of acute running with different cognitive engagement on children’s inhibitory control function,mood,and brain activation,as well as the mediating role of mood in the influence of exercise intervention on inhibitory control.Methods:Ninety primary school fourth grade children were randomly divided into the cognitive running group(n=30),the traditional running group(n=30),and the control group(n=30),respectively,for 20 min of moderate-intensity cognitive engagement running,traditional running or rest.The Go/No-go paradigm cognitive task and functional near-infrared spectroscopy(fNIRS)were used to investigate the changes of inhibitory control function and brain activation of prefrontal cortex in children before and 15 min after exercise intervention,and the Two-Dimensional Mood Scale(TDMS)was used to measure the the changes of children’s mood status immediately before and after exercise intervention.Results:1)After both traditional running and cognitive engagement running,children’s reaction times in Go/No-go cognitive task were significantly shortened(P<0.01),with cognitive engagement running significantly improving the accuracy of nogo trail(P<0.01).2)Compared to traditional running and the control group,cognitive engagement running more effectively enhanced children’s levels of pleasure and arousal(P<0.01),and significantly increased oxyhemoglobin(Oxy-Hb)concentration level in the left dorsolateral prefrontal cortex(l-DLPFC)(P<0.01).3)The increase in Oxy-Hb concentration level in l-DLPFC was significantly positively correlated with the increase in arousal level(r=0.31,P<0.01),and significantly negatively corre‐lated with the increase in reaction time(r=-0.22,P<0.05).4)The arousal level of mood had a masking effect between exercise intervention and the reaction time of inhibitory control.Conclu‐sions:Cognitive engagement exercise can more effectively improve mood and enhance inhibitory control function in children.Its neural mechanism may involve enhancing children’s i
