 The study found that physical activity has many positive effects on the health of school-aged children and youth. It recommends that children and youth aged 5 to 17 years old should accumulate an average of at least 60 minutes per day of moderate to vigorous intensity physical activity. Additionally, it suggests that more vigorous intensity activities should be incorporated or added when possible, including activities that strengthen muscles and bones. Finally, aerobic activities should make up the majority of the physical activity, while muscle and bone strengthening activities should be incorporated on at least three days of the week.
