The aim of this study was to identify neurophysiological correlates for previously reported positive effects of exercise on academic achievement in school children using a distributed source localization algorithm. Electro-cortical activity of 11 school children (9-10y) was recorded before and after a moderate 15-min bike exercise. Data were analyzed using standardized low resolution brain electromagnetic tomography (sLORETA) in the alpha (7.5-12.5Hz) and beta (12.5-35Hz) frequency range. We were able to show a significant increase in alpha activity post-exercise, which could be localized in the precuneus. Moreover a distinct decrease in beta activity could be noticed post-exercise in left temporal areas including Wernicke's area. We propose that apart from health-promoting aspects school sport serves a second even more important challenge. On a central level a well observed overall state of physical relaxation after exercise is reflected by a more synchronized state in the precuneus. We speculate this to be responsible for an increase in concentrativeness and cognitive function post-exercise. Moreover a previously reported increase in academic achievement post-exercise could be directly linked to exercise induced neuroplasticity in regions that are relevant for language processing.
本研究旨在使用分布式源定位算法，确定以前报道的运动对学龄儿童学业成绩的积极影响的神经生理学相关性。在进行适度的 15 分钟自行车运动之前和之后，记录了 11 名学龄儿童（9-10 岁）的脑电活动。使用标准化低分辨率脑电磁层析成像（sLORETA）在 alpha（7.5-12.5Hz）和 beta（12.5-35Hz）频率范围内对数据进行了分析。我们能够显示出运动后 alpha 活动的显著增加，该活动可以在楔前叶中定位。此外，运动后还可以在包括韦尼克区的左侧颞区中观察到明显的 beta 活动减少。我们提出，除了促进健康的方面外，学校体育还面临着第二个甚至更重要的挑战。在中枢水平上，运动后身体放松的整体状态观察到更同步的状态在楔前叶中反映出来。我们推测这是运动后集中力和认知功能增加的原因。此外，以前报道的运动后学业成绩提高可以直接与语言处理相关区域的运动诱导神经可塑性相关联。
