Approximate Time to Steady-state Resting Energy Expenditure Using Indirect Calorimetry in Young, Healthy Adults
A new study in the Frontiers in Nutrition Journal provides evidence on the assessment of the time to reach steady state (SS) during indirect calorimetry in young, healthy adults.
The aims of this prospective study are to determine an approximate time to reach SS using open-circuit IC and establish the appropriate duration of SS needed to estimate REE. To achieve these aims, a 30-min IC measurement with no prior rest was conducted in young, apparently healthy adults. .
The study findings show "that in a population of young, healthy adults the duration of the IC measurement period when measuring REE can be as little as 10 min, with the first 5-min being discarded. Steady state occurred by the second 5-min segment and continued to meet the SS criteria. Standardizing the IC measurement provides repeatability among researchers who want to best estimate REE, and thus extrapolated to 24-h TEE. Also, this information is important for researchers and practitioners working in a variety of settings for acutely and timely examining energy expenditure for better nutrition and physical activity intervention recommendations".
