摘　　要：目的探究不同强度短时有氧运动对久坐大学生自我控制的影响及时程特点,为久坐大学生提供运动建议。方法选取48名久坐大学生随机分为中强度组、高强度组和对照组,中强度组和高强度组分别以60%~69%和70%~79%的最大心率完成30 min跑台运动,对照组不进行任何体力活动。采用Stroop色词任务对3组受试者干预前、干预后即刻、干预后30 min、干预后60 min 4个时间点进行自我控制行为学指标测量。结果重复测量方差分析结果显示,3组受试者在准确率指标上差异无统计学意义(p>0.05);在反应时指标上,组别主效应显著(F_((2,45))=3.877,p<0.05,η_(p)^(2)=0.147),组别与时间交互作用极其显著(F(6,135)=11.181,p<0.001,η_(p)^(2)=0.332),简单效应分析显示中强度组在运动后30min和60min显著低于对照组(p<0.05),高强度组与对照组差异无统计学意义(p>0.05)。结论中等强度短时有氧运动会显著提升久坐大学生的自我控制,这一效果会出现在运动后30 min,并可持续至运动后60 min;高强度短时有氧运动可能会损害久坐大学生的自我控制,并且在60 min内无法恢复至基线水平。Objective To explore the effect of acute aerobic exercise with different intensity on self-control of sedentary college students,and provide exercise suggestions for sedentary college students.Methods Forty-eight sedentary college students were randomly divided into the medium intensity group,the high intensity group and the control group.The medium intensity group and the high intensity group completed a 30 minute treadmill exercise with a maximum heart rate of 60%~69%and 70%~79%,respectively.The control group did not carry out any physical activity.Stroop color word task was used to measure the self-control behavior indicators of the three groups of subjects at four time points,before intervention,immediately after intervention,30 min after intervention,and 60 min after intervention.Results The results of repeated measurement ANOVA showed that there was no significant difference in the accuracy index among the three groups(p>0.05).On the reaction time index,the main effect of the group is significant(F_((2,45))=3.877,p<0.05,η_(p)^(2)=0.147),the interaction between group and time is extremely significant(F(6,135)=11.181,p<0.001,ηP2=0.332),simple effect analysis showed that the moderate intensity group was significantly lower than the control group at 30 min and 60 min after exercise(p<0.05),and there was no significant difference between the high-intensity group and the control group(p>0.05).Conclusion Medium intensity acute aerobic exercise will significantly improve the self-control of sedentary college students,which will occur 30 min after exercise and last until 60 min after exercise.High intensity acute aerobic exercise may damage the self-control of sedentary college students,and can not recover to the baseline level within 60 min.
