Physical activities enhance the cerebral blood flow, and regulate hippocampal neurogenesis and learning. This study was designed to probe the effect of the physical activity program on the preschoolers’ working memory. Participants were 39 5-to-6-year-old preschoolers. 21 boys were participating physical activity program and 18 boys un-participating served as control group. The physical activity program was scheduled with kicking/soccer for six months duration. After the physical activity program, the preschoolers’ working memory was estimated with Sternberg’s task and the Sentence Test of WPPSI-R. And we recorded the preschoolers’ EEG when they were implementing Sternberg’s task. It was found primarily that the α2 (11-13 Hz) at T4 power of the participating group was more active (p < .05) than the un-participating group. And other frequencies of brain wave (θ, α1, and α2) in frontal lobe, parietal lobe, and temporal lobe were no group difference. Response performances were so. It was concluded that physical activity program may increase the activity of hippocampus related to semantic memory retrieval and performance.
