【摘要】：目的探讨急性有氧运动对超重青少年反应抑制功能与干扰抑制功能效益的影响。方法采用标准的Go/Nogo范式与Flanker任务分别测评行为抑制和干扰抑制,首先比较超重青少年与正常体重青少年在抑制功能上的差异性,探究超重青少年抑制功能是否存在弱势;其次,将超重青少年随机分成运动组和对照组,分别经过20 min中等强度有氧运动干预和静坐阅读后,检测其抑制功能。结果 (1)与对照组相比,超重青少年的Nogo正确率显著降低,Go反应时显著减慢,Flanker任务的反应时显著延长;(2)运动组后测的Nogo正确率显著提高,Flanker任务的不一致刺激正确率显著提高。结论超重青少年表现出较弱的反应抑制和干扰抑制,20 min的急性中等强度有氧运动能够促进超重青少年的抑制功能。
[Abstract]:Objective to investigate the effects of acute aerobic exercise on response inhibition and interference inhibition in overweight adolescents. Methods behavior inhibition and interference inhibition were evaluated by standard Go/Nogo paradigm and Flanker task respectively. First, the difference between overweight adolescents and normal weight adolescents in inhibition function was compared to explore whether the inhibition function of overweight adolescents was weak or not. Overweight adolescents were randomly divided into exercise group and control group. After 20 min of moderate aerobic exercise intervention and sit-down reading, the inhibitory function of overweight adolescents was measured. Results (1) compared with the control group, the correct rate of Nogo in overweight adolescents was significantly lower than that in the control group, and the response time of Flanker task was significantly slower than that of the control group, (2) the correct rate of Nogo measured after exercise group was significantly higher than that of the control group, and the correct rate of inconsistent stimulation of Flanker task was significantly increased in the exercise group. Conclusion overweight adolescents showed weak response inhibition and interference inhibition of 20 min of acute moderate intensity aerobic exercise can promote the inhibitory function of overweight adolescents.
