If you\u2019ve ever finished a run and seen your Garmin flash up with a new VO\u2082 Max estimate, you\u2019ve probably wondered: how accurate is the Garmin VO\u2082 Max, really?\u00a0<\/span><\/p>\n

VO\u2082 Max<\/span>, or <\/span>maximal oxygen uptake<\/span>, is often described as the gold standard for cardiovascular fitness. It indicates the maximum amount of oxygen your lungs can inhale during maximal exercise and is strongly linked with endurance performance, longevity, and recovery capacity.\u00a0<\/span><\/p>\n

Garmin watches use algorithms to estimate this value from your workouts \u2014 but how close is that number to the truth? In this article, we\u2019ll unpack what VO\u2082 Max actually measures, how Garmin calculates VO\u2082 Max, and where the differences arise between real laboratory testing and fitness tracker estimation.<\/span><\/p>\n
