Also, VO2max is a very marketing-oriented indicator! But you’re right: the most accurate way to measure VO2max is breath-by-breath gas analysis during a maximal test. Wrist wearables (Garmin, Apple Watch, etc.) infer VO2max from HR/pace/power models it's convenient, but estimates and sport-dependent. Running vs cycling VO2max can differ for the same athlete.

Our device measures breath-by-breath VO2, VCO2 in real time and resolves individual breaths, which may unlock new respiratory metrics for researchers. The accuracy of threshold value measurements is equally important: ventilation threshold 1, ventilation threshold 2, tidal volume etc.
