【摘要】：目的:研究不同时间中等强度体育锻炼对初中生执行功能与学业成绩的影响,并采用路径分析方法探讨执行功能在体育锻炼与学业成绩关系中所起的作用。方法:按照方便取样的原则选取扬州市某中学初二年级5个教学班共250名学生作为实验对象,采用随机抽样的方式分为4个实验班和1个对照班,进行不同时间中等强度体育锻炼的干预,实验干预持续8周。实验前后对所有被试的执行功能和学业成绩进行测量,执行功能测量采用E-prime系统在计算机上完成,学业成绩采用被试实验前后的两次期末考试的学业成绩。结果:(1)不同时间中等强度体育锻炼对初中生执行功能整体、抑制功能和转换功能具有显著影响,对刷新功能没有显著影响;(2)在45min体育锻炼中累积27±1.35min中等运动强度的初中生,语文、数学和英语的学业成绩均有提高且效果最好,但不同时间中等强度体育锻炼对初中生的语文、数学和英语学业成绩影响没有显著差异;(3)在45min体育锻炼中累积22.5±1.35min、27±1.35min中等运动强度的学生,执行功能的转换功能对学业成绩的间接效应具有显著性。结论:(1)中等强度体育锻炼的累积时间达到20min以上对初中生抑制功能和转换功能的效益最为显著;(2)持续8周、每周3次、每次累积持续25min左右的中等运动强度体育锻炼对初中生学业成绩具有积极影响;(3)体育锻炼主要通过执行功能的转换功能对学业成绩产生影响。
[Abstract]:Objective: to study the effect of middle intensity physical exercise on the executive function and academic achievement of junior high school students at different times, and to explore the role of executive function in the relationship between physical exercise and academic achievement by means of path analysis. Methods: according to the principle of convenient sampling, 250 students in 5 teaching classes of middle school grade two in Yangzhou were selected as experimental objects. The students were divided into 4 experimental classes and 1 control class by random sampling. The intervention of moderate intensity physical exercise at different time lasted for 8 weeks. The executive function and academic achievement of all the subjects were measured before and after the experiment. The executive function was measured by E-prime system on the computer. The academic results were obtained from the two final examinations before and after the experiment. Results (1) moderate intensity exercise had significant effects on executive function, inhibition function and conversion function of junior high school students at different time, but had no significant effect on refreshing function. The junior high school students who accumulated 27 卤1.35min moderate exercise intensity in 45min exercise had significant effects. The academic achievement of Chinese, mathematics and English are all improved and the effect is the best, but the middle intensity physical exercise at different time is good for the Chinese of junior high school students. There was no significant difference between mathematics and English academic achievement. (3) there was a significant indirect effect of executive function conversion function on academic achievement among students who accumulated 22.5 卤1.35 minutes or 27 卤1.35min moderate exercise intensity in 45min exercise. Conclusion (1) the cumulative time of moderate intensity physical exercise above 20min is the most significant benefit to the inhibition and conversion function of junior high school students.) it lasts for 8 weeks, 3 times a week. The average intensity of physical exercise with cumulative sustained 25min has a positive effect on the academic achievement of junior high school students.) physical exercise has an effect on academic achievement mainly through the conversion function of executive function.
