What is VO2 Max?
VO2 max, or maximal oxygen uptake, is a common measurement linked to aerobic endurance that many athletes use to determine their overall fitness. VO2 max is the measurement of the maximum volume of oxygen that you can consume during intense, or maximal exercise. It is measured as milliliters of oxygen used in one minute per kilogram of body weight (ml/kg/min). It is one factor that may help determine an athlete's capacity to perform sustained exercise. A high VO2 max is necessary for success in endurance events.
Amazfit uses Firstbeat method to estimate your VO2 max. The calculation relies on a combination of personal background information (age, gender, height, weight, etc.) and data collected during your activity. This includes a focus on heart rate and running/walking speed. VO2 max varies greatly between individuals.
