“A breakthrough in exercise physiology and human performance assessment...”

Introducing the K5

K5, the 4th generation of the most popular family of wearable metabolic systems, is a device designed for the measurement of metabolic parameters (VO2, VCO2, Ventilation, HR, energy expenditure, and more...) either in the field or in laboratory.

More than 28 years and 2000 units sold worldwide have been passed since COSMED introduced the first generation of compact metabolic systems. The result of such an experience has been carefully implemented in a complete new piece of technology incorporating latest design in terms of mechanics, electronics and software providing researchers, sport professionals and clinical users new limits in exploring human exercise physiology.
