Energy expenditure measurements are reproducible in different whole-room indirect calorimeters in humans.

ABSTRACT:

Objective

This study aimed to evaluate the agreement of commonly reported energy metabolism measurements obtained from two different whole-room indirect calorimeters (WRICs).

Methods

Nine healthy adult volunteers were evaluated over four separate 24-hour periods in a crossover design, twice in two different WRICs of different sizes, each operated according to the Room Indirect Calorimetry Operating and Reporting Standards published in 2020. The reproducibility of repeated measurements was quantified by the coefficient of variation (CV) and intraclass correlation coefficient (ICC).

Results

The CVs between and within each WRIC for average 24-hour carbon dioxide production rate (VCO₂ ) and oxygen consumption rate (VO₂ ), 24-hour energy expenditure (
