5. Physical activity is a suggested behaviour to protect against overweight and obesity2 and is recommended as a principle intervention strategy to reduce obesity in children3 However, only 12% of Canadian children are meeting current physical activity recommendations.4.

6. With constrained and competing school agendas, insufficient levels of recommended physical activity have been found within physical education class.5

7. Increased demand on after-school care6 has lead to greater evaluation of physical activity levels within the after-school setting.7

8. Previous interventions in the after-school environment have outlined success at facilitating increased physical activity and positive associations with obesity.8-10
