VO2 max shows the biggest amount of oxygen that the body is able to take and use during strong physical work. The words in the name explain quite a lot easily: “V” means volume, “O2” means oxygen, and “max” means the biggest. Think of it as the power of an engine.

It measures how well the body uses oxygen during movement. The more oxygen one manages to take during heavy action, the better the oxygen supply of the person.
VO2 Max: What It Is and How to Improve It
One measures it in milliliters of oxygen for each kilogram of body mass in a minute. High VO2 max means that the body well grabs oxygen from the air and carries it to the muscles. It shows how well the heart pumps blood to the muscles and how well those muscles pull oxygen from the blood.
When oxygen enters the lungs, it starts chemical processes in the muscle cells that help to produce energy for movement.
VO2 max commonly receives the title of the most reliable marker for heart and blood vessel health and oxygen fitness. Athletes use it to check their oxygen skill before or during exercises. Even so, it forms only part of the hole image.
Pace at the oxygen limit or the lactate threshold better predicts actual top activity, because they consider several factors together, where VO2 max is only one of those.
In a good laboratory one does the test by running on a treadmill, fixed bike or rowing machine, while one wears a mask or tube that is tied to a device for checking oxygen. A simple method is also the Cooper test, where one runs or walks as far as possible while exactly 12 minutes. The covered distance relates directly to VO2 max. One can measure it also by means of formulas based on resting heart rate and body mass.
Genetics, age, exercises and general health all limit the possibilities of VO2 max. The highest heart rate drops by 0.6 to 0.8 beats per minute each year, and aging reduces the mitochondria in the working muscles. Studies from 1993 showed that once inactive older men and women that exercised during nine months to a year both raised their VO2 max on average by 20 percent.
High-intensity interval exercise ranks among the most efficient methods for improving VO2 max. Intervals of one to six minutes with same times for work and pauses are usually seen as good for such training. Changing the strength of the efforts is also useful. When VO2 max grows, the resting heart rate usually drops.
During the same exercise level, the usual heart rate should be lower. Even so, such training does not work for yearlong usage. Too much of it can flood the body.
One can build it quickly, but it losesitself just as quickly.
Runners and fitness watchers track VO2 max by means of mass, distance, speed and heart rate, although those data not always match perfectly. Still, following the value over time helps to note changes in fitness.
