VO2max

DEVO2max (maximale Sauerstoffaufnahme)

VO2max is the maximum rate at which you can use oxygen during intense exercise. It is usually expressed in mL/kg/min. By the Fick principle, it equals your oxygen delivery (cardiac output and hemoglobin) times how much your muscles extract at the mitochondria. VO2max is among the strongest predictors of all-cause death. A higher VO2max is strongly tied to lower long-term risk across cohort studies (for example, Mandsager 2018). That makes it a central marker of cardiorespiratory fitness in longevity research.
