A mixed method systematic review of primary school based interventions to promote physical activity and/or reduce sedentary behaviour.

Evidence confirms few children engage in the recommended 60 minutes of daily moderate-to-vigorous physical activity and highlights a decline in participation from around 5 to 7 years. Children spend approximately 40% of their waking hours at school and form early health behaviours in childhood; primary schools are therefore an important setting to promote physical activity. This systematic review was conducted to ascertain the effectiveness of school based physical activity interventions in 5–11 year old children
