CosAma {PASWR}

Cosmed Versus Amatek

Description

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 stored in CosAma.
