VO2 max: What is it and how can you improve it? - Harvard Health
Spend enough time with a group of endurance athletes — swimmers, cyclists, runners, cross-country skiers, anyone who needs to sustain an aerobic effort — and sooner or later, someone is bound to bring up V02 max. VO2 max is an objective way to tell just how fit you are. A high VO2 max correlates to better physical fitness and is associated with a lower risk for cardiovascular disease and increased longevity.
And if you know your VO2 max, you can use it as a tool to help you exercise more efficiently. The V in VO2 max stands for volume, while O2 stands for oxygen. As such, VO2 max measures how much oxygen your body consumes while exercising. When you breathe, your lungs absorb oxygen and transport it your red blood cells, which carry the oxygen to all of your body's organs and muscles.
Your muscle cells need oxygen to generate adenosine triphosphate ATP. ATP provides the main energy source your muscles need hur uppskatta vilo vo2 do their work. The more oxygen you can breathe in, the more ATP your muscles produce, creating the energy to fuel your muscles and power your workout. This is also why you breathe faster while exercising. If you have a higher VO2 max, that means your heart and lungs are more effectively supplying blood to your muscles, and that your muscles are efficiently extracting and using oxygen from your blood.
That's why a high VO2 max is a good indicator of a high fitness level. You'll wear a heart rate monitor and a special mask to record how much oxygen you're taking in and how much carbon dioxide you're exhaling while running on a treadmill, riding a stationary bike, or doing any other aerobic activity that gets your heart pumping. The intensity of exercise will slowly ramp up until you're exercising at full capacity.
A maximal exercise test is hur uppskatta vilo vo2, but relatively short — between 10 and 20 minutes total. Other than athletes, most people don't need to know their exact VO2 max. There are other ways to estimate your VO2 max using an online tool.
How to measure your VO2 Max and why it's important
If you are walker, a good choice for the calculator is the one-mile walk test. Measure the time it takes to walk one mile as fast as you can. Immediately after completing the mile, check your heart rate using a portable monitor or take your pulse.
Enter your readings and the other information needed in the calculator. Age, gender, elevation, and activity levels all affect your VO2 max score. Of these four factors, the easiest to control is your activity level. While your VO2 max tends to decrease as you age, it's possible to greatly slow its decline by remaining active. While your starting VO2 max number can reflect your current fitness level, it's more important to focus on improving your readings over time.
VO2 Max Chart: What's a Good VO2 Max by Age?
Increasing your VO2 max is associated with a reduced risk of heart disease, diabetes, cancerand stroke. Plus, better fitness is associated with improved sleep and quality of life. Get your heart pumping. You can improve your VO2 max by doing any aerobic exercise that gets your heart pumping — the more vigorous, the better. If you're not currently active, walking may be vigorous enough to trigger improvements in your VO2 max score.
Incorporate intervals. If you're already quite active, try incorporating sessions of high-intensity interval training. Try doing an interval training workout several times per week, interspersed with slower, longer-duration activities.
VO2 max: What is it and how can you improve it?
Switch up your workout routine. Your body is constantly adapting. If you're primarily a swimmer, try cycling. If you usually train at a slow, steady pace, ramp things up. If you usually work out for 30 minutes, try adding 10 minutes to your routine. All of these changes force your body to work harder to adapt. Lose weight. Because relative VO2 max is measured relative to your weight, simply losing weight can boost your VO2 max.
