VO2 Max shows the biggest amount of oxygen that the body is able to take and use during physical activity. The “V” means volume, “O2” relates to oxygen, and “max” means the highest level. In short words, it helps to measure the fitness level of people.

A rise in VO2 Max shows that the body better takes oxygen from the air and moves it to the muscles. The more oxygen arrives to them during training, the more easily one feels the effort at a given intensity. Almost all devices show it as milliliters of oxygen for one kilo of weight in one minute.
VO2 Max: What It Is and How to Improve It
One measures VO2 Max exactly only in a lab. Such a test requires expert workers, a special mask that gathers every bit of breathed oxygen and breathed out carbon dioxide, along with a step-by-step plan. Smart watches try to estimate it, but those values commonly err.
For instance, one lab gave 52 while the Apple Watch estimated around 41. That shows qutie a big difference.
Watch ratings base themselves on heart rate and running speed. If someone reaches the same work with a low heart rhythm, the rating of VO2 Max will be better. But the device does not know truly what happens inside the body.
It does only a rough guess.
Body mass matters a lot hear. One counts VO2 Max by sharing the oxygen use of 60 seconds by weight in kilos. So being thin helps to reach a higher value.
Heavier people need a bigger VO2 Max simply to move their weight just as quickly as a lighter person.
Genetics, age and general health all affect the limits of VO2 Max. Also sexes differ. Lower levels of hemoglobin and a slightly smaller heart in women can explain differences in oxygen use, without depending on body size. One study showed that before inactive older adults that trained during nine months to a year raised their VO2 Max on average by 20 percent, and the gains were equal for men and women.
High-intensity interval training ranks among the most effective ways to raise VO2 Max. Intervals of one to six minutes with equal work and rest periods usually are seen as good for VO2 Max. Long medium-fast runs also are useful for improving watch-based ratings, because they mix steady speed with data about heart rhythm. Only zone-2-training does not move the value a lot. Its main target is to build a base for fitness, so that the body later handles more hard sessions.
When VO2 Max grows, the resting heart rate usually drops. At the same effort level, the middle heart rate during activity also should drop. VO2 Max is commonly called one of the strong measures for long life.
Being in the upper quarter matters most for healthy results. Before, one thought it was the perfect measure of fitness, but now it shows as only one part ofsporting wellness.
