    • Practical utility and reliability of whole-room calorimetry in young children 

      Janssen, Xanne; Cliff, Dylan; Okely, Anthony D.; Jones, Rachel A.; Batterham, Marijka; Ekelund, Ulf; Brage, Søren; Reilly, John J. (Journal article; Peer reviewed, 2012-09-19)
      The use of whole-room calorimetry (WRC) in young children can increase our understanding of children's energy balance. However, studies using WRC in young children are rare due to concerns about its feasibility. To assess ...
