VO2 Max : Ce que signifie vraiment votre nombre Garmin
Le VO2 Max mesure l'efficacité avec laquelle votre corps utilise l'oxygène pendant l'exercice. C'est le meilleur prédicteur de la forme d'endurance — et votre Garmin l'estime à chaque course.
Day 18: VO2 Max Explained
"Your Garmin shows a VO2 Max number, but… what does it actually mean?"
VO2 Max is one of those numbers that sounds intimidating but is actually simple once you understand it. And understanding it will change how you train.
What is VO2 Max?
VO2 Max stands for "maximum volume of oxygen consumption." It measures the maximum amount of oxygen your body can use per minute, per kilogram of body weight — expressed as mL/kg/min.
The higher your VO2 Max, the more oxygen your muscles can use, which means more energy production, and the ability to sustain harder efforts for longer.

How Garmin estimates it
Garmin uses an algorithm that combines your heart rate and pace/power during outdoor runs. The more data points it has, the more accurate the estimate. It's not lab-accurate, but it's directionally correct and tracks your fitness trends well.
How to improve it
- Zone 2 training: High volume of easy aerobic work builds your aerobic base
- Intervals: Short high-intensity efforts push your VO2 Max ceiling higher
- Consistency: VO2 Max improves over months, not days
