VO2 Max simply is the biggest amount of oxygen that your body really fits to take during strong physical work. Breaking the word, one finds volume (the V), oxygen (O2) and the highest level (max). It is like the force of engine in your body, a basic tool for guessing how much skill for taking oxygen you have, when everything becomes hard.

Usually, higher VO2 Max wants to say lower heart rate always. Below happens, that your body learns to better use oxygen from the air and carry it to the places where muscles need it. During training muscles receive more oxygen, the whole seems less hard and you can keep the effort for more time.

What Is VO2 Max and How to Improve It

When your VO2 Max climbs, something good happens, your resting heart rate usually drops. Even working at same level of strentgh, your usual heart rate stays lower than before.

Most experts rate VO2 Max as the most reliable standard for checking heart and blood fitness together with the skill to resist long aerobic work. It is that, about what serious long-range sportsmen care always (swimmers), cyclists, runners, skiers across land. They mention it commonly, because it provides a clear, fair number four follow your fitness.

For real and steady rating, you need a test in a laboratory. You will Run on a treadmill, will pedal on a fixed bike or will row on a machine, wearing a mask or tube bound to a device for checking oxygen. The tool counts energy according to the amount of oxygen that you use, and the carbon dioxide that you breathe out, during the strength grows.

Can not go to a lab? The Cooper-test works well as a replacement, simply you walk or Run as quickly as it is possible during 12 minutes on flat ground, and the covered distance points something about your VO2 Max. Current training watches give guesses using data about heart rate, although they not always match with real accuracy.

Your genes clearly define the base for your possible VO2 Max. Even so, almost every person can expand it, if they want to work quite hard to pass their aerobic limit. Training with high strength and breaks carries the main load here. Short breaks last from one to six minutes, with same time for rest between them…

Here is what causes increase of VO2 Max. Mixing different levels of strength in your usual exercises also helps, and good advice is that easy training helps it improve over time.

The problem is that one can not do VO2 Max training during the whole year. Too much high-intense work leads to overload and weakening. It grows quickly, but slowly drops.

For normal people, losing extra weight helps to expand your VO2 Max, because it measures based on body mass. Studies show that typical older adults that trained regularly for nine months to a year, got around 20 percent more, pretty seriously, whether they were men or women.

VO2 Max really matters, but it forms only a chip of the whole picture. Aerobic threshold speed and lactate threshold better predict actual lasting ability in life, because they tie several parts together. Movement cost and time to tire also matter, and they do not simply transfer between different sports.

The highest heartrate naturally drops when one ages, what is worth remembering.
