摘要
目的:探讨急性中等强度有氧运动对手机依赖者抑制控制与决策功能的影响及其潜在的神经机制。方法:采用随机交叉试验设计,28名手机依赖大学生分别参与20分钟中等强度有氧运动和静坐两种实验条件。通过Stroop任务与爱荷华博弈任务(Iowa gambling task,IGT)分别评估抑制控制与决策能力。结果:中等强度有氧运动显著缩短Stroop任务反应时并诱发了更大的P3波幅,但未影响N2波幅。此外,中等强度有氧运动显著提高IGT任务总得分,而对FRN及P3波幅无显著影响。结论:急性中等强度有氧运动可提升手机依赖者认知资源投入水平,改善抑制控制功能,并降低风险决策倾向,提高决策功能。
Objective:To investigate the effects of acute moderate-intensity aerobic exercise on inhibitory control and decision-making function in mobile phone dependent individuals and its potential neural mechanisms by event-related po-tential(ERP)technology.Methods:A randomized crossover design was conducted.Twenty-eight mobile phone-dependent university students participated in two experimental conditions:20-min moderate-intensity aerobic exercise condition and sitting control condition.Inhibitory control and decision-making were measured with the Stroop task and the Iowa Gaming Task(IGT).Results:Moderate-intensity aerobic exercise significantly shortened Stroop task reaction time and induced greater P3 amplitude,but did not affect N2 amplitude.Meanwhile,moderate-intensity aerobic exercise significantly in-creased total IG index,but there was no significant effect on FRN and P3 amplitudes.Conclusion:Acute moderate-intensity aerobic exercise increases the level of cognitive resource engagement and improves inhibitory control function.Meanwhile,it decreases the propensity for risky decision-making and promotes decision-making function in mobile phone dependent individuals.
