【摘要】：抑制功能作为人类高级认知执行功能的子成分之一,与大学生的日常生活密切相关,如何科学的通过有氧运动提高抑制功能变得尤为重要。有氧运动对于抑制功能具有一定促进作用,中等强度相比大强度和小强度的有氧运动对抑制功能的影响最为积极,所以中等强度有氧运动可以更好地刺激抑制功能的提高,进而提高执行功能。[1]研究目的:通过对有氧运动过程加以音乐干预,运用事件相关电位(ERP)技术探究音乐干预下的有氧运动对于认知控制子成分中的反应抑制能力是否具有积极的影响,为设计科学合理的运动处方提供理论依据。实验对象:在成都体育学院文科系(新闻系、经管系、外语系、医学系)中选取男性大学生30名,平均年龄为20.1岁,IPAQ(短问卷)代谢当量结果小于600METs,将其随机分为实验组与对照组。实验方法:首先对两组被试进行实验前测试(基测),之后实验组在三十分钟的有氧运动过程中全程加入音乐干预,对照组只进行三十分钟的有氧运动全程无音乐干预,得到实验后测。研究使用E-prime软件编辑的改良版GO/NOGO经典实验范式,通过电脑屏幕呈现给被试让其做出相应的反应,同时记录反应过程中的行为数据。脑电数据采用德国Brain Products公司的Recorder记录系统,Ag/Ag Cl电极帽记录64导脑自发电位(EEG)进行脑电信号的采集,最后使用BP Analyzer对脑电数据进行离线分析。利用SPSS软件对行为数据结果GO反应时与NOGO正确率和脑电数据结果N2、P3波幅、潜伏期进行分析处理,结合其脑地形图,作为认知控制功能的评价结果。本研究实验结果如下:(1)行为结果表明,实验组的GO反应时前后测差异显著(P0.05),对照组的GO反应时后测较前测提高,实验组的NOGO正确率方面有提高但差异不显著,对照组的NOGO正确率方面有提高但前后差异小于实验组。(2)事件相关电位数据显示:(1)实验组的N2波幅在GO/NOGO任务类型和电极点上主效应显著(P0.05),实验组小于对照组;N2潜伏期在前后测、GO/NOGO任务类型与电极点主效应显著(P0.05),实验组前后测试差异大于对照组。(2)实验组P3波幅在前后测、GO/NOGO任务类型与电极点主效应显著(P0.05),实验组后测高于对照组;P3潜伏期在前后测、GO/NOGO任务类型与电极点上主效应显著(P0.05),实验组潜伏期后测短于前测。结论:(1)中等强度有氧运动对大学生提高GO反应时有积极影响,音乐干预下的有氧运动GO反应时高于单纯的有氧运动,表明音乐干预下的有氧运动对抑制功能的增强更具有显著性。(2)中等强度有氧运动对NOGO正确率的提高起到了积极作用,提高了抑制控制的成功率。(3)音乐干预下的有氧运动使被试的N2潜伏的周期变短,N2波幅缩短,并且优于对照组,提高了行为前策略制定的时间为下一个行为做好更充分的准备。(4)音乐干预下的有氧运动被试P3潜伏期周期变短、P3波幅增高,并显著优于对照组,提高了认知资源和注意信息的分配效率,进而产生更好的行为表现。(5)在有氧运动过程中加入音乐干预可以更好的促进大学生快速进行信息识别、合理分配注意资源以及保持高效的抑制控制。
[Abstract]:As one of the sub components of the executive function of human advanced cognition, inhibition function is closely related to the daily life of college students. How to scientifically improve the inhibitory function through aerobic exercise is particularly important. Aerobic exercise has a certain effect on the inhibition function, and the moderate intensity is more effective than the high intensity and small intensity of aerobic exercise. The effect of energy is most positive, so medium intensity aerobic exercise can better stimulate the enhancement of inhibitory function, and then improve the purpose of performing functional.[1] research: by music intervention to the aerobic exercise process, using event related potential (ERP) technology to explore the reaction of aerobic exercise under the interference of music to cognitive control subcomponents. The experimental object: 30 male college students were selected from the Department of journalism, management, foreign language and medical department of Chengdu Sport University. The average age was 20.1 years old, and the metabolic equivalent of IPAQ (short questionnaire) was less than 600METs. The experimental group and the control group. Experimental methods: first of all two groups of subjects were tested before the experiment (base test), then the experimental group joined the music intervention during the thirty minute aerobic exercise, and the control group had only thirty minutes of aerobic exercise without music intervention, and the experimental post test was obtained. The improved version of GO/NOGO edited by E-prime software was studied. The classic experimental paradigm was presented to the subjects by the computer screen to make the response and record the behavior data in the reaction process. The EEG data used the Recorder recording system of the German Brain Products company, the Ag/Ag Cl electrode cap recording the 64 brain spontaneous potential (EEG) for the acquisition of EEG signals, and the final use of BP Analyzer to the EEG. The data are analyzed off-line. The SPSS software is used to analyze the correct rate of the behavior data and the NOGO accuracy and the results of the EEG data, N2, P3 amplitude, and incubation period. The results of the cognitive control function are as a result of the cognitive control function combined with the brain topographic map. The results of this study are as follows: (1) the result of behavior indicates that the test group's GO reaction time and back test difference The GO reaction in the control group was higher than that of the previous test, and the accuracy of NOGO in the experimental group was improved but the difference was not significant. The NOGO correct rate in the control group was improved but the difference was less than the experimental group. (2) the event related potential data showed: (1) the N2 amplitude of the experimental group was shown on the main effect of the GO/NOGO task type and the electrode point. (P0.05), the experimental group was less than the control group; the N2 latency was measured before and after, the main effect of the GO/NOGO task type and the electrode point was significant (P0.05). The difference of the test group was greater than that of the control group. (2) the P3 amplitude of the experimental group was measured before and after, the GO/NOGO task type and the main effect of the electrode point were obvious (P0.05), the experimental group was higher than the control group; the latency of P3 was measured before and after, and the test group was measured before and after, and the latency of P3 latency was measured before and after, The main effect of the GO/NOGO task type and the electrode point was significant (P0.05), and the latency of the experimental group was shorter than the pre test. Conclusion: (1) the moderate intensity aerobic exercise has a positive effect on improving the GO response to the college students. The aerobic exercise GO reaction under the music intervention is higher than the simple aerobic exercise, which indicates that the aerobic exercise under the music intervention increases the inhibitory function. (2) moderate intensity aerobic exercise played a positive role in improving the correct rate of NOGO and improved the success rate of inhibition control. (3) the aerobic exercise under the intervention of music shortened the incubation period of the N2, shortened the amplitude of N2, and was superior to the control group, and raised the time for the formulation of the pre behavior strategy for the next behavior. More fully prepared. (4) the incubation period of the aerobic exercise under the music intervention was shorter, the P3 amplitude increased, and significantly better than the control group, which improved the allocation efficiency of cognitive resources and attention information, and then produced better behavior performance. (5) the addition of music intervention to the aerobic exercise could improve the college students' rapid progress. Information recognition, rational allocation of attention resources and efficient control of inhibition.
