INTRODUCTION: A third of all children spend at least 60 min·d in moderate to vigorous physical activity (MVPA) as recommended by the World Health Organization. We investigated the distribution of objectively measured physical activity (PA) intensities achieved by schoolchildren during physical education (PE) and organized youth sports (OYS) and the contribution of PE and OYS to the achievement of the PA recommendations. METHODS: In two surveys, PA of 396 children was measured using accelerometry during typical school weeks. Proportions (%) of sedentary behavior, light PA, and MVPA per day and particularly during sports were assessed in children 6-17 yr old. Adjusted odds ratios (AOR) were calculated to analyze the association between frequency (d·wk) and duration (min·wk) of PE and OYS and meeting the PA recommendations. RESULTS: Average proportions of MVPA during PE and OYS ranged between 15% and 31%. Between 68% and 74% of children (6-10 yr) and between 27% and 37% of adolescents (11-17 yr) met the PA recommendations. In both age-groups, PE and OYS on at least 2 d·wk were both significantly associated with meeting the PA recommendations (AOR for PE = 3.60, 95% confidence interval [CI] = 2.05-6.31; AOR for OYS = 3.83, 95% CI = 2.09-6.99), compared with no PE or no OYS in that week. Likewise, significant AOR values were found for >90 min of PE per week (AOR = 3.48, 95% CI = 2.03-5.98) and >120 min of OYS per week (AOR = 3.72, 95% CI = 2.01-6.89), compared with no PE or no OYS in that week, respectively. CONCLUSION: Schoolchildren spent less than one-third of PE and OYS in MVPA. PE and OYS were found to support children and adolescents to engage sufficiently in MVPA as recommended by the World Health Organization.
