Sixty minutes is currently the shortest testing duration for 24-h resting energy expenditure (24-h REE) utilizing whole-room indirect calorimetry. Show that recalculated 30-min extrapolated 24-h REE from previously published 60-min metabolic data are valid. Propane consumption linearity was determin...
