摘要
目的:阐明运动训练是否能够影响大脑功能可塑性变化,以及不同任务态下运动员如何诱发大脑皮层功能重组。方法:选取18项研究中的任务态下362名被试的功能磁共振成像(functional magnetic resonance imaging,fMRI)数据,采用激活似然估计法(activation likelihood estimation,ALE)计算体素被激活的分布情况。结果:运动员组在任务状态下的脑活动产生4个达到显著水平的激活簇;对照组在任务状态下的脑活动产生5个达到显著水平的激活簇;运动员组与对照组相比,运动员组显著激活左侧上顶叶和下顶叶、右侧额下回和额中回,对照组显著激活辅助运动区;在预判任务中,运动员有更广泛的脑区激活,而在执行任务中,对照组有更广泛的脑区激活。结论:长期的运动训练使得运动员的大脑出现功能可塑性变化,表现为减少了在动作执行时与动作控制有关的脑区活动,增加了在预判时与认知理解有关的脑区活动。
Objectives:To clarify whether sports training can affect brain functional plasticity and how acquiring athletes induces cortical reorganization in different sports task states.Methods:Selected 362 subjects'functional Magnetic Resonance Imaging(fMRI)data in the task state of 18 studies,and used Activation Likelihood Estimation(ALE)to calculate the distribution of voxels.Results:Athletes'brain activity in the task state produced four activation clusters;in the control group,the brain activity in the task state produced five activation clusters;compared with control group,athletes activated Left Superior Parietal Lobule and Inferior Parietal Lobule,Right Inferior Frontal Gyrus and Middle Frontal Gyrus.Compared with athletes,control group activated Suppl ementary Motor Area.In prediction task,athletes had wider activation of brain regions,while in execution task,control group had wider acti vation.Conc.lusions:long-term sports training has resulted in functional plasticity changes in athletes'brains,which are manifested in in the reduction of brain activity related to motor control during execution,and the increase of brain activity related to cognitive understanding in the prediction.
