VO2 max bases mainly on the limit of oxygen that your body fits to absorb from the air, transport through the blood and use for energy during hard exercise. Breaking down the words in the name: “V” means volume “O2” oxygen, and “max” simply the highest value. One measures it by means of milliliters of oxygen per kilo of weight per minute.
Imagine it like the horsepower of a car, it shows the ability of your body to use oxygen when you push limits.
What is VO2 max and how to improve it
Widely, higher VO2 max means better fitness, while lower marks weakness. That shows that your body learned more well to pull oxygen from the air and deliver it to the needed places. Indeed, the value depends on two main parts: the ability of your heart to pump blood to the muscles and the skill of thsoe muscles to take oxygen from the blood.
After breath, that oxygen joins in chemical process inside the muscle cells, that gives energy for your activity.
One commonly calls VO2 max the most reliable standard for measuring heart fitness and aerobic level. Athletes apply it daily as base for control training periods. Even so, here the spot, it does not cover everything.
The lactate threshold or aerobic threshold commonly shows more well your result in long-range events, because they consider more many factors that affects actual activities.
The most exact mode to measure it is by means of run on treadmill, cycling on still machine or rowing on a rower, while you wear mask or tube connected to oxygen meter. Even so, you do not need labs. For instance, the test of Cooper requires that you run or walk as far as you can four 12 minutes on flat surface, later enter the covered distance in a formula to value your VO2 max. Smart watches give ratings also, based on weight, speed, distance and data about heart rhythm, mainly, low heart rhythm for same work signals higher VO2 max. Warning: those devices not always accurate, so treat their numbers as estimates, not as absolute truth.
Genetics play big role in VO2 max. Age affects also. Your maximum heart rhythm drops by around 0.6 to 0.8 beats per year as you age, and alike changes weaken the power plants in your active muscles. Women usually have a bit lower ability to transport oxygen because of fewer hemoglobin and widely more little bodies.
Interestingly, a study from 1993 showed that older men and women between 60 and 65 years, that trained for around 9 months to a year, both raised their VO2 max by almost 20 percent.
High intensity interval training ranks between the best methods for raising VO2 max. Push yourself during 2 to 4 minutes without pause, later rest enough between intervals, works well. Long sessions in zone 2 help also. Combining different levels of intensity commonly gives the best results.
Recall that VO2 max grows quickly, but fades also quickly, and too much high intensity work can cause overload. As your VO2 max climbs, you will notice that your resting heart rhythm sinks andthat the same speed feels less heavy.
