Recess offers primary school age children the opportunity to engage in physical activity, though few studies have detailed the physical activity levels of children in this environment. The physical activity levels of 270 children ages 6-11 years from 18 schools were monitored on 1 school day using heart rate telemetry. Data revealed that boys engaged in higher levels of moderate-to-vigorous and vigorous physical activity (MVPA) than did girls during recess (26 and 20 min, respectively). These results suggest that recess can make a worthwhile contribution to the recommended 60 min of MVPA per day.
