Validity and Reliability of the VO2 Master for Oxygen Consumption and Ventilation Assessment



“The VO2 Master had an acceptable validity and test-retest reliability for most intensities tested and may be an appealing option for field-based VO2 and VE analysis… Average absolute VO2 was <0.2 L/min different between analyzers at all stages.”

Validity and Reliability of the VO2 Master


“Typical percent error was less than 2% for all metrics, easily achieving the 3% recommendation by the Australian Sports Institute. Intra and inter reliability of the VO2 Master were excellent with ICC coefficients greater than 0.99, and minimum detectable changes less than 3.5% for VO2 and 1.5% for ventilation.”
