The accuracy and precision of energy expenditure (EE) measured using the whole-body indirect human calorimeter (IHC) at the National Institute of Health and Nutrition in Japan were evaluated. A total of 40 six-hour ethanol combustion experiments were performed. VO<sub>2</sub> and VCO<sub>2</sub> computed by the currently used real time algorithm were compared with the expected values from the weight of ethanol consumed. The mean±SD of the ratio between the computed and expected values (computed value/expected value) of VO<sub>2</sub>, VCO<sub>2</sub> and ∑EE were 101.0±2.1, 100.6±1.7 and 100.9±1.9%, respectively. The mean values and SDs indicated that the accuracy and precision of our IHC are acceptable. However, increases of SDs were observed for short combustion periods corresponding to small amounts of ethanol combustion (e.g., less than 20g of ethanol).
