This research presents a meta-analysis of studies examining the relationship between recreational physical activity and children's performance in STEM (Science, Technology, Engineering, and Mathematics) subjects, with a specific focus on math and science. While previous research has established a positive correlation between physical activity and cognitive function, there is a significant gap in understanding how recreational physical activity in particular influences STEM education. Through a comprehensive analysis of 24 relevant studies, this meta-analysis provides valuable insights into the impact of physical activity on how children perform math and science. The results demonstrate a significant and positive effect, suggesting that integrating recreational physical activities into STEM education could enhance children's achievement in these critical subjects.
