| 目的 采用meta分析观察运动对改善超重及肥胖人群神经可塑性的价值。方法 检索Web of Science、PubMed、PsycINFO及中国知网自建库至2024年8月1日关于运动干预后超重或肥胖人群脑激活变化的功能MRI(fMRI)文献,采用激活似然估计(ALE)法分析数据,得到脑区激活簇坐标。结果 最终共纳入11篇文献,包括186名超重及肥胖受试者。运动后,所有受试者右额中回激活增加,左小脑前叶、左楔前叶及右楔叶激活减少;其中,未成年人右扣带回及右颞上回激活增加,左小脑前叶、双侧中央前回激活减少;成年人双侧豆状核、右额中回、右扣带回及右海马旁回激活增加,双侧楔前叶激活减少。结论 运动可改善超重及肥胖人群执行功能、工作记忆、注意力和运动控制相关脑区激活程度,且运动后未成年人与成年人之间改善情况存在差异。 |

| Objective To observe the value of exercise for improving neuroplasticity in overweight and obese people using meta-analysis. Methods Articles of functional MRI (fMRI) studies about brain activation changes in overweight or obese people after exercise published in Web of Science, PubMed, PsycINFO and CNKI were searched from the establishment of database to August 1, 2024. The data were analyzed with activation likelihood estimation (ALE), and the coordinates of brain activation clusters were obtained. Results A total of 11 articles were ultimately enrolled, including 186 overweight or obese subjects. After exercise, the activation of the right middle frontal gyrus increased in all subjects, while of the left anterior lobe of cerebellum, left precuneus and right cuneus decreased. Among them, activation of the right cingulate gyrus and right superior temporal gyrus in minors increased, while of the left anterior lobe of cerebellum and bilateral precentral gyrus decreased. And the activation of the bilateral lentiform nuclei, right middle frontal gyrus, right cingulate gyrus and right parahippocampal gyrus in adults increased, while of the bilateral precuneus decreased. Conclusion Exercise could improve activation level of brain regions related to executive function, working memory, attention and motor control in overweight or obese people, which were different between minors and adults. |
