Summary
This study looked at whether a before-school physical activity program called BOKS could improve body weight, thinking skills, and quality of life in 188 children aged 5 to 14. The program ran three mornings per week for 12 weeks. Researchers measured changes in BMI, executive function, and self-reported quality of life.
