摘　　要：目的:探讨急性高强度间歇运动(high-intensity interval exercise,HIIE)和持续中等强度有氧运动(continuous moderate-intensity aerobic exercise,CMIAE)对超重个体食物抑制功能的影响。方法:采取被试内设计,以超重个体(n=28)为研究对象,选取与食物相关的刺激材料,通过行为测量和事件相关电位技术探讨急性HIIE和CMIAE对超重个体食物Go/NoGo反应时和正确率以及脑神经活动N2、P3波幅的影响。结果:1)2种运动干预后被试完成食物Go/NoGo任务中Go试次的反应时显著更短(P<0.001),而Go试次正确率和NoGo试次正确率无显著差异;2)在食物Go/NoGo任务中,图片类型对N2波幅的主效应显著,食物类图片刺激诱发的N2波幅显著高于中性图片;3)在Cz电极上,仅在安静对照条件下,食物NoGo试次中高热量食物图片的P3波幅显著高于Go试次(P<0.05),而2种运动条件下这一差异并不显著(P>0.05)。结论:1)超重个体对食物类刺激存在早期的注意偏向;2)急性HIIE和CMIAE可降低超重个体对高热量食物注意资源的分配;3)急性HIIE对于提升超重个体的食物抑制能力可能是一种更为省时有效的运动方案。Objective:To explore the effects of acute high-intensity interval exercise(HIIE)and continuous moderate-intensity aerobic exercise(CMIAE)on the food inhibition function of overweight individuals.Methods:A within-subjects design was adopted to study overweight individuals(n=28),To investigate the effects of acute HIIE and CMIAE on food Go/NoGo response time and correctness as well as brain neural activity N2 and P3 wave amplitudes in overweight individuals.Results:1)Subjects completed the food Go/NoGo task with significantly shorter Go response times under both exercise conditions(P<0.001),whereas there was no significant difference in Go correct and NoGo correct rates;2)overweight individuals showed a picture type main effect in the food Go/NoGo task,i.e.,food-like picture stimuli evoked significantly higher N2 amplitude than neutral pictures;3)on Cz electrodes,overweight individuals were found to have significantly higher P3 amplitude on NoGo trials than on Go trials(P<0.05)for high-calorie food pictures,in the quiet control condition only,whereas this difference did not exist in the two exercise conditions(P>0.05).Conclusions:1)There is an early attentional bias towards food-like stimuli in overweight individuals;2)acute HIIE and CMIAE reduce the allocation of attentional resources to high-calorie foods in overweight individuals;3)acute HIIE exercise is a time-saving and effective exercise regimen for enhancing food inhibition in overweight individuals.
