摘　　要：目的:以大脑神经抑制功能为切入点,利用事件相关电位(ERP)技术从脑电图水平解释短时自行车运动影响超重大学生抑制功能的具体机制。方法:以某高校16名超重大学生作为被试,采用功率自行车对其进行短时运动干预;采用Flanker范式测量抑制功能,分析其行为和脑电数据;采用SPSS 25.0进行行为学数据分析;采用MATLAB、EEGLAB、FIELDTRIP进行ERP数据处理与分析。结果:(1)在Flanker任务相同刺激和不同刺激任务上,分别对运动干预前后的反应时进行配对样本t检验,结果显示,都具有显著性差异;抑制冲突反应时(不同刺激任务反应时减去相同刺激任务的反应时)前后测差异性不显著,但后测抑制冲突反应时有明显缩短趋势。(2)完成相同刺激任务和不同刺激任务时在运动干预前后诱发的N2振幅均显示有显著性差异,前额叶的电压值都有所增高。结论:短时自行车运动可激活超重大学生大脑前额叶皮层的兴奋性,能对其抑制功能进行显著的改善。Taking the brain nerve inhibition function as the starting point,ERP technology was used to explain the specific mechanism of short-term cycling exercise affecting the inhibition function of overweight college students from the level of EEG.Methods:In this paper,16 overweight college students in a university were taken as subjects,and the short time exercise intervention was carried out with power bicycle.The Flanker paradigm was used to measure inhibition function,behavior and EEG data.MATLAB,EEGLAB and FIELDTRIP were used for ERP data processing and analysis.Results:(1)For the same stimulus and different stimulus tasks in Flanker's task,sample T-test was conducted on responses before and after exercise intervention,respectively,and the results showed significant differences.There was no significant difference in the suppression of conflict response(when the response of different stimulus tasks was subtracted from the response of the same stimulus task),but there was a significant shortening trend in the suppression of conflict response after the test.(2)N2 amplitude induced by the same stimulus task and different stimulus tasks before and after exercise intervention showed significant difference,and the voltage value of the prefrontal lobe increased.Conclusion:Short-term cycling exercise can activate the excitability of the prefrontal cortex of overweight college students,and can significantly improve its inhibition function.
