VO2 max in short is the biggest amount of oxygen that your body gets to take during exercises at a hard level. It is like the horsepower in an engine, it shows how well your body truly uses oxygen for work. Looking at the word, everything is clear: “V” stands for volume, “O2” for oxygen, and “max” simply for maximum.

Many folks see it as the main tool for checking heart health and fitness level. Here is the basic reason: the more oxygen you manage to take in during working the less heavy it feels and the more you can keep going. A strong VO2 max helps your body become more efficient in pulling oxygen from the air and sending it to the places where it must reach; to your muscles.
What is VO2 max and how to test and improve it
Everything happens by pumping blood from your heart to those muscles, while they at the same time pull oxygen from that flow. When you breathe in, the oxygen enters into chemical reactions inside your muscle cells, that creates energy. The value itself is measured in milligrams of oxygen for every kilo of weight, counted every minute.
How best to find your exact value? By testing in a lab. You will work at full force on a treadmill, fixed bike or rower, using a mask or tube connected to an oxygen analyzer.
The devices count the energy based on how much oxygen you use and how much carbon dioxide you release. Even so, if a lab is not available, there is an easier way. The Cooper test simply requires that you run or walk at your top speed during exactly 12 minutes, and the covered distance helps to estimate where your VO2 max stands.
Your fitness watch can also help count it, although the accuracy is not always the same. Those tools use your weight, the done distance, your pace and heart rate, to later combine them into a result. A lower heart rate for the same task shows better VO2 max. As your VO2 max goes up, you commonly notice that your resting heart rate drops.
Genetics play a big role in your natural ceiling. Even so, almost every person can improve their value by means of regular exercise near their oxygen limit. Exercise at high intensity with intervals works grate for that.
Those intervals, that last between one and six minutes with almost equal times for work and pause, form the main method for raising VO2 max. Also sessions in the second zone help well. Combining various levels in your daily plan over time helps to keep the ceiling high. The downside?
If you exercise too hard, you quickly burn out. It builds force, grows quickly, but disappears just as fast if you stop.
Endurance athletes. Swimmers, cyclists, runners, cross-country skiers, care about VO2 max for good reason. But truly, it does not show everything.
Oxygen limit and pace of lactate threshold more often predict your real output, because they consider several things at once. Sex also affects this; lower levels of hemoglobin and a smaller heart partly explain that. Studies showed that previously inactive older adults who trained between nine months and a year improved their VO2 max by around 20 percent, regardless of sex.
The maximum heart rate similarly drops by around 0.6 to 0.8 beats perminute each year as you age.
