The relationship between physical activity, self-regulation and cognitive school readiness in preschool childrenLimited research exists on the pathways through which physical activity influences cognitive development in the early years. This study examined the direct and indirect relationships between physical activity, self-regulation, and cognitive school readiness in preschool children.

Our Child Physical Activity, Health and Development team focuses on improving children’s physical activity levels, health and development. We work to uncover the best environments, policies and programs to facilitate physically active lifestyles for lifelong health and wellbeing.

Developmental trends in young children’s device-measured physical activity and sedentary behaviourKnowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls.
