【摘要】：目的:探讨有氧体育锻炼与执行功能的"剂量效应"。方法:采用追踪研究设计,以270名大学生为被试,按性别、锻炼强度、频率、时间分成18个实验组,进行16周有氧功率自行车锻炼计划。使用Flanker任务、2-back任务和More-odd shifting任务在锻炼前、1次锻炼后、8周、12周和16周分别测试被试的抑制、刷新和转换功能,考察有氧体育锻炼对执行功能的影响。结果:锻炼的强度、频率和时间对执行功能提高的贡献分别为0.927、0.872、0.813;强度主效应下,男大学生执行功能改善效果为大强度中等强度小强度,女性则为中等强度小强度大强度;频率主效应下,男、女大学生改善效果为高频率中等频率小频率;时间主效应下,男、女大学生改善效果为16周12周8周4周1次。结论:小强度高频率有氧体育锻炼适用于女大学生的运动干预方案,中等强度中等频率则适用于男大学生的运动干预方案,且以12周为单元周期。
[Abstract]:Objective: to explore the dose effect of aerobic exercise and executive function.Methods: 270 college students were divided into 18 experimental groups according to sex, exercise intensity, frequency and time.The inhibition, refresh and conversion functions of subjects were tested by Flanker task 2-back task and More-odd shifting task after 8 weeks and 16 weeks of exercise respectively, and the effects of aerobic exercise on executive function were investigated.Results: the contribution of exercise intensity, frequency and time to the improvement of executive function was 0.927 ~ (0.872) and 0.813, respectively. Under the main effect of intensity, the effect of improving the executive function of male college students was high intensity, medium intensity and small intensity, while that of female was medium intensity and high intensity.Under the main effect of frequency, the improvement effect of male and female college students was high frequency, medium frequency and small frequency, while that of male and female college students was 16 weeks, 12 weeks, 8 weeks, 4 weeks and 4 times under the main effect of time.Conclusion: the low intensity and high frequency aerobic exercise is suitable for female college students' exercise intervention, while the moderate intensity moderate frequency is suitable for male college students' exercise intervention program, and the unit cycle is 12 weeks.
