摘要
目的:基于大脑局部一致性(Re Ho)方法探测小球类运动员静息状态下脑功能活动的可塑性变化。方法:收集小球类学生运动员和与之匹配的对照人群,采集静息态功能磁共振数据,计算大脑局部一致性Re Ho指标。结果:运动员组在左侧前扣带回、脑岛、丘脑和小脑蚓部的ReHo值高于对照组,这些脑区是负责心脏——血管调节和反馈的自主神经反应环路脑网络的重要节点。结论:运动员左侧前扣带回、脑岛、丘脑和小脑蚓部脑区存在更有效的自主神经反应环路,以在快节奏小球类运动中提高感知、集中、运动计划和快速反应。
Objective： To explore the plasticity of brain activity of small - ball players in resting state using regional homogeneity （ReHo）. Methods： Recruited small- ball student athletes and matched control people, collected resting -stated functional magnetic resonance imaging （fMRI） data, and calculated Reho indicators of cerebral regional homogeneity. Results： Athletes had higher ReHo values in left anterior cingulate cortex, insula, thala- mus and vermis as compared with control group. These cerebral regions are important knots of autonomic neural circuit responsible for cardiovascular adjustment and feedback. Conclusion ： The improvement of ReHo values in the autonomic neural circuit suggests that there is a more effective automatic neural circuit which helps improve perception, concentration, movement planning and fast responses in high -paced small -ball games.
