Reproducibility of the COSMED's Fitmate metabolic system in measuring steady-state cycling energy expenditure.

A French study examined the reproducibility of the Fitmate metabolic system in measuring breathing gas during a cycling exercise.

The study (in French language), by the University of Nice Sophia-Antipolis, aimed to demonstrate the reproducibility of respiratory variables (VE and VO2) using a desktob metabolic system like Fitmate.

Twenty-one participants performed during two sessions three 5-min exercises at submaximal intensities (16, 18 et 21 km/h). The results indicated a good reproducibility for VE and a satisfactory reproducibility for VO2 and cycling efficiency.

The study conclusions were that "the Fitmate portable metabolic analyzer provides reproducible measures of VO2 and VE during steady-state exercise that allows the assessment of energy expenditure in a simple manner in a clinical framework".
