Gender differences in physical activity during fifth-grade physical education and recess periods

Boys are typically more physically active than girls, but schools have the potential to promote health-related physical activity for all children. This study investigated gender differences in children's physical activity levels during physical education (PE) classes and unstructured recess periods. The activity levels of 91 fifth-grade children were assessed by accelerometer (Caltrac) on 3 days. Results indicated that children's activity levels were low to moderately stable from day to day in both environments. Boys and girls had similar activity levels during PE, t(89) = 1.49, p = .140, but boys were significantly more active than girls during recess, t(89) = 3.27, p = .002. Girls were significantly more active during PE than they were at recess, t(51) = 2.08, p = .043. The results suggest that structured PE classes may provide similar amounts of physical activity for both genders.
