The Cosmed is a portable metabolic system. A study at Appalachian State
University compared the metabolic values obtained from the Cosmed to those
of a reference unit (Amatek) over a range of workloads from easy to maximal
to test the validity and reliability of the Cosmed. A small portion of the
results for VO2 (ml/kg/min) measurements taken at a 150 watt workload are
A data frame with 14 observations on the following 3 variables:
measured VO2 with Cosmed
measured VO2 with Amatek
