摘要
目的通过事件相关电位(ERP)技术,探究8周中强度乒乓球运动对抑郁症状大学生言语工作记忆(Verbal Working Memory,VWM)的干预效果及其认知神经加工机制。方法招募60名抑郁症状大学生,按1∶1的比例随机分配为实验组和对照组,实验组接受为期8周、每周3次、每次30 min(5 min热身+20 min乒乓球运动+5 min整理)、心率为65%~75%HR_(max)的乒乓球运动,对照组不进行任何形式的干预。在实验前后测试VWM及其ERP成分(N2、P3)和抑郁症状。结果实际纳入52名抑郁症状大学生(实验组25人,对照组27人)。VWM正确率的组别与时间交互效应显著(F(1,50)=4.269,P=0.044,偏η^(2)=0.079),实验组正确率在运动干预后显著提高(平均差异为0.039,95%CI为0.015~0.062,P=0.002),反应时的组别与时间交互效应不显著(F(1,50)=2.291,P=0.136,偏η^(2)=0.044),N2潜伏期的组别和时间交互效应显著(F(1,50)=4.588,P=0.037,偏η2=0.084),N2波幅、P3潜伏期与波幅的各阶交互效应均不显著。结论8周中强度乒乓球运动可有效缓解大学生抑郁症状,并提高言语工作记忆的正确率,缩短任务态N2潜伏期。
Objectives To investigate the effects of 8-week moderate-intensity table tennis exercise on verbal working memory(VWM)and its cognitive neural processing mechanisms in college students with depressive symptoms using event-related potential(ERP)technology.Methods Sixty college students with depressive symptoms were recruited and randomly assigned to either an exercise group or a control group in a 1∶1 ratio.The exercise group underwent an 8-week table tennis intervention(3 sessions/week,30 min/session:5 min warm-up+20 min table tennis+5 min cool-down)at 65%−75% of maximum heart rate(HR_(max)),while the control group received no intervention.VWM performance,ERP components(N2,P3),and depressive symptoms were assessed before and after the intervention.Results A total of 52 participants(exercise group:25;control group:27)were included in the final analysis.A significant group×time interaction was observed for VWM accuracy(F(1,50)=4.269,P=0.044,partial η^(2)=0.079),with the exercise group showing significant post-intervention improvement(mean difference=0.039,95% CI=0.015−0.062,P=0.002).No significant interaction was found for reaction time(F(1,50)=2.291,P=0.136,partial η^(2)=0.044).A significant group×time interaction emerged for N2 latency(F(1,50)=4.588,P=0.037,partial η^(2)=0.084),whereas no significant interactions were detected for N2 amplitude,P3 latency,or P3 amplitude.Conclusions Eight weeks of moderate-intensity table tennis exercise effectively alleviated depressive symptoms and enhanced VWM accuracy in college students,accompanied by shortened N2 latency during task processing.
