A validation study of Quark RMR by CRNHR was published on the 6th issue of the European Journal of Clinical Nutrition and Metabolism.

In this study the measurements of two different indirect calorimeters from COSMED (Fitmate and Quark RMR) were correlated and analysed for better adequacy.

COSMED's Quark CPET has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup.

COSMED's Fitmate has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup.
