A new validation on Fitmate reliability during exercise tests was recently published on the Scandinavian Journal of Clinical & Laboratory Investigation.

The purpose of this study was to assess the reliability of the FitMate ™ metabolic system and to compare its reliability with the previously studied portable breath-by-breath analyzers Cosmed K4b2.

Expired gas, ventilation were recorded in 50 subjects, using in a random order among four sessions, either the FitMate™ or the Cosmed K4b2. No differences in oxygen consumption were observed between the two systems whatever the intensity.

The study concudes that "reliability values for the FitMate ™ system were high for light to heavy intensity and could be compared with those recorded with the Cosmed K4b2". COSMED K4b2 during submaximal walking in healthy adults.
