"Physical activity and sports are generally promoted for their positive effect on children's physical health … There is also a growing body of literature suggesting that physical activity has beneficial effects on several mental health outcomes … In addition ... there is a strong belief that regular participation in physical activity is linked to enhancement of brain function and cognition, thereby positively influencing academic performance."
"The increasing pressures to improve academic scores often lead to additional instructional time for subjects such as mathematics and language at the cost of time for being physically active … [T]he literature provides inconclusive evidence on the positive longitudinal relationship between physical activity and academic performance. However, there is a strong general belief that this relationship is present, and research in this area is ongoing."
