  • Title: The Energy Cost of Household Chores, Rollerblading, and Riding Scooters in 9- to 14-Year-Old Children.
    Author: Ridley K, Olds T.
    Journal: J Phys Act Health; 2016 Jun; 13(6 Suppl 1):S75-7. PubMed ID: 27392385.
    Abstract:
    BACKGROUND: To improve the scope of the Youth Compendium of Energy Expenditures, a range of everyday activities of varying intensity should be measured. This study measures the energy cost of children undertaking common household chores, rollerblading and riding a foot-propelled scooter. METHODS: Participants were 9- to 14-year-old children. A metabolic cart was used to measure oxygen cost (VO2) of a variety of household chores. A Cosmed K4b2 portable oxygen analyzer was used to measure VO2 during rollerblading and riding a scooter at self-selected speeds. Energy costs for each participant were calculated as child METs. RESULTS: Mean child MET costs for the household chores ranged from 1.3 to 3.6 METs. Rollerblading and riding a scooter yielded mean child MET costs of 6.5 and 6.3 METs respectively. CONCLUSIONS: Household chores were found to be of light to moderate intensity, while rollerblading and riding a scooter were vigorous activities.
