N2 - Background: The assessment of physical activity (PA) and energy expenditure (EE) in youth is complicated by inherent variability in growth and maturation during childhood and adolescence. This study provides descriptive summaries of the EE of a diverse range of activities in children ages 7 to 13. Methods: A sample of 105 7- to 13-year-old children (boys: 57%, girls: 43%, and Age: 9.9 ± 1.9) performed a series of 12 activities from a pool of 24 activities while being monitored with an indirect calorimetry system. Results: Across physical activities, averages of VO2 m⋖kġmin-1, VO2 Lmin-1, EE, and METs ranged from 3.3 to 53.7 m⋖kġmin-1, from 0.15 to 3.2 Lmin-1, from 0.7 to 15.9 kca⋖min-1, 1.5 MET to 7.8 MET, respectively. Conclusions: The energy costs of the activities varied by age, sex, and BMI status reinforcing the need to consider adjustments when examining the relative intensity of PA in youth.
