摘　　要：探讨短时有氧运动对执行功能的影响是否与运动强度和性别有关,为从运动强度和性别角度选择合理的有氧运动干预方案改善执行功能提供基础。研究采用混合设计,选取30名大学生(男女人数各半),使用功率自行车实施30分钟的不同强度有氧运动,使用Flanker任务、2-back任务和数字More-oddshifting任务分别测查被试基线、小强度短时有氧运动、中强度短时有氧运动和大强度短时有氧运动后执行功能的抑制、刷新和转换三个子功能的变化,结果表明:不同强度的短时有氧运动对执行功能产生选择性的积极影响,且不随性别变化而改变。Executive functions are important for successful adaptation and performance in real-life situations.Physical exercise has been broadly recommended as a major non-pharmacological measure to improve executive functions throughout one＇s life.But some fundamental questions still remain,such as at what degree of intensity physical exercise can be effective.As far as this paper is concerned,few studies have been done on the effects of acute aerobic exercise of different intensities on executive function.The present study attempts to investigate the effects of acute aerobic exercise of different intensities on college students＇ executive function.The present study adopts a mixed design involving 30 college students（15 male,15 female） as the subjects,who are supposed to fulfill three tasks,namely,the Flanker task,the 2-back task and the More-odd shifting task in each stage of the experiment.Meanwhile the exercise-induced changes in executive functions,i.e.inhibition,updating and shifting,will be recorded respectively at the four different stages in terms of intensity degrees：a baseline,a light cycling exercise,a moderate cycling exercise and a high cycling exercise.The time interval between any two stages of the experiment is no less than 7 days and the order of the four stages in the experiment are counterbalanced among the participants in order to minimize the potential practice effects.It is found that acute aerobic exercise of different intensities has significant effects on college students＇ executive function,specifically,inhibition：F（3,84） = 2.76,p0.05;updating：F（3,84） = 18.78,p0.01;shifting：F（3,84） = 18.25,p0.01.It is also found that the effects of acute aerobic exercise on executive function are not significant from the perspective of gender,specifically,inhibition：F（3,84） = 0.55,p0.05;updating：F（3,84） = 1.53,p0.05;shifting：F（3,84） = 0.46,p0.05.These results suggest that the effects of acute aerobic exercise on executive functions are significantly influenced by in
