Physiological Profiling


The most comprehensive Physiological profiling

Extract a Comprehensive View of Your Physiology While Working “In The Trenches”


The COSMED K5 is the top-of-the-line, most innovative and versatile wearable metabolic system for exercise physiology and human performance and nutritional assessment. Currently, the Metabolic Efficiency Test is conducted in the “lab” under controlled conditions. But now, physiological profiling will be able to be conducted “in the trenches” to provide the most comprehensive nutritional assessment: fuel analysis combined with GPS and other sport sensors that will allow for data analysis during real-time measurements anywhere and under any environmental condition.

The K5 is the only metabolic system on the market that allows for measurement of the following components:

  • Metabolic

    • Energy Expenditure

    • Substrate (Carb + Fat) Use

  • Cardiovascular

    • Heart Rate

    • Estimated Cardiovascular Output

  • Kinematics

    • Speed

    • Distance

    • Cadence

    • Stride Length

    • Bike Power

  • Respiratory

    • Oxygen Consumption (VO2)

    • Carbon Dioxide Production (VCO2)

    • Ventilation (VE)

    • Respiratory Frequency (Rf)
