Physical Activity, Fitness, and Cognitive Function in Children and Adolescents

Abstract

From the playground to youth sports, the benefits of physical activity for children and adolescents are primarily known. Less understood is how participation influences cognitive function at different stages of development. This chapter aims to summarize the literature on child and adolescent physical activity, fitness, and cognitive performance by translating empirical research to school and community settings. The specific effects of physical activity vary by intensity, mode, volume, and domain. This review suggested that physical activity and fitness were positively associated with higher cognitive function. Children who are aerobically fit and regularly physically activite are faster, more accurate responders and tend to do better in school. Participation in light to vigorous intensity physical activity cognitively benefits children. Additional benefits come from cognitively demanding (e.g., team sports) and vigorously intense (e.g., jumping rope) activities. Because benefit varies by physical fitness component and physical activity type, it is recommended that preschool children participate in an assortment of movements for 3 h a day, working up to 60 min of moderate-to-vigorous physical activity by age 6. Comprehensive approaches across multiple settings, offering opportunities to participate in physical activity, have the most significant potential for enhancing cognitive health among children and adolescents.
