Associations between daily physical activity and executive functioning in primary school-aged children

Area of Science:

• Pediatric Health
• Cognitive Science
• Exercise Physiology

Background:

• Limited evidence exists on the relationship between children's daily physical activity and executive functioning.
• Aerobic fitness shows a positive association with executive functioning in children, but daily activity patterns are less understood.

Purpose of the Study:

• To investigate associations between objectively measured daily physical activity and executive functioning in children.
• To analyze the impact of total physical activity volume, sedentary behavior, and moderate-to-vigorous physical activity on executive functions.

Main Methods:

• Cross-sectional study involving 80 primary school children (ages 8-12).
• Physical activity measured using accelerometers.
• Executive functions assessed via Stroop test (inhibition), Visual Memory Span test (working memory), Trailmaking test (cognitive flexibility), and Tower of London (planning).

Main Results:

• Increased sedentary behavior correlated with poorer inhibition (r = -0.24).
• Higher total physical activity volume was associated with better planning ability (Tower of London score: r = 0.24; execution time: r = -0.29).
• Moderate-to-vigorous physical activity showed a moderate correlation with improved planning execution time (r = -0.29).

Conclusions:

• Children should reduce sedentary time and increase overall daily physical activity.
• Total volume of physical activity, including light-intensity activity, is significantly related to executive functioning.
• Further research should explore both the quantity and quality of physical activity in relation to children's cognitive development.
