Physical education contributes to total physical activity levels and predominantly in higher intensity physical activity categories

Children's engagement in physical activity of a vigorous intensity or higher is more effective at promoting cardiorespiratory fitness than moderate physical activity. It remains unclear how higher intensity physical activity varies between days when schoolchildren participate in physical education (PE) and non-PE days. The purpose of this study was to assess how PE contributes to sedentary behaviour and the intensity profile of physical activity accumulated on PE days compared to non-PE days. Fifty-three schoolchildren (36 girls, 11.7 + 0.3 years) completed five-day
