MC-PeakPro Research Grade Metabolic Cart

For Elite Athletes, where every second counts, consider an upgrade to the MC-PeakPro.

The MC-PeakPro system includes everything needed for recording and measuring:

  • Basal Metabolic Rate (BMR)
  • Resting Metabolic Rate (RMR)
  • Respiratory Exchange Ratio (RER)
  • Sedentary to Light Activity
  • VO2 and VCO2
  • VO2 Max
  • Anaerobic Threshold (AT)/ Ventilatory Threshold (VT)


Validation of Metabolic System
