Energy balance
Standardized validation protocols, including regular combustion or gas infusion tests, are required to ensure the accuracy and precision of whole-room indirect calorimetry systems for measuring human energy expenditure.
If you are using a whole-room calorimeter, you must validate its performance regularly using traceable standards (like combustion or gas infusion) and report these validation results (accuracy, precision, zero tests) in your publications. This ensures your energy expenditure data is comparable across studies and laboratories.
The panel recommends regular calibration of all calorimeter system components to traceable standards... We recommend reporting gas exchange rates... as primary outcomes for these validation tests... The panel also recommends regular system validation using combustion as a minimum standard.
Why this rating
This is a consensus guideline from an international panel of experts, representing the highest level of methodological agreement in the field.
