中文摘要： 当前一些研究结果提示：有氧运动是一种改善儿童执行功能的有效手段，但尚缺乏全面的科学证据支持该观点，突出表现为尚未清楚揭示有氧运动改善儿童执行功能的脑机制，关键问题在于未有研究阐明有氧运动对儿童脑执行功能区可塑性的影响。我们前期对此探索发现：有氧运动可以改善儿童执行功能，且与某些执行功能脑区的可塑性改变有关，为该问题研究提供了理论和实践基础；但在脑的可塑性指标、长期效应和执行功能多维结构方面的研究有待进一步深入。为此，本项目拟以执行功能发展关键期的儿童为研究对象，综合利用体育测量技术、心理测量技术和多模态磁共振成像技术，追踪研究长期有氧运动对儿童脑执行功能区可塑性的影响，探讨有氧运动、儿童执行功能及其脑区可塑性的关系，阐明有氧运动改善儿童执行功能的脑机制，为确立有氧运动是促儿童执行功能健康有效手段的观点，提供新的科学依据。

英文摘要： Some preliminary findings suggest: aerobic exercise is an effective means to improve children executive function (EF), but the comprehensive scientific evidence to support this view is still lack. The brain mechanism of beneficial effects are really not known, the key question, which aerobic exercise affect on brain region plasticity of children's EF, is not undertaken any study. We pre-discoveried that aerobic exercise can improve children's EF, and the certain brain regions plasticity of children's EF, which provide a theoretical and practical foundation for the key question. However, there are three important aspects that remain to need to further probe: brain plasticity index, long-term effects and multi-dimensional structure of executive function. In this respect, the current project sets out to seek to investigate the effect of aerobic exercise on brain region plasticity of children's EF, further explore the relationship among aerobic exercise, children 's executive function, its brain region plasticity, finally clarify aerobic exercise to improve children 's executive function and its brain mechanisms, in order to provide new scientific evidence for which aerobic exercise is a healthy and effective way to improve children EF.
