VO2 Max and Longevity – Optimizing Your Healthspan

VO2 max — the maximum amount of oxygen your body can use during exercise — is one of the strongest biomarkers of longevity, and it declines by about 10% per decade after age 25 (Hawkins & Wiswell, 2003, Sports Med). This decline is driven in part by falling mitochondrial function in muscle, where oxygen is converted into usable energy. Mitopure, a clinically validated form of Urolithin A, activates mitophagy to renew mitochondria; in a randomized trial of middle-aged adults, 1,000 mg daily raised estimated VO2 max by 14% over baseline — a positive trend that did not reach statistical significance versus placebo — while significantly improving muscle strength by up to 12% (Singh et al., 2022, Cell Reports Medicine).

What is VO2 Max?

Aerobic capacity, also called VO2 max, is the rate at which our muscles use oxygen during exercise. It is written as “amount of oxygen consumed per kilogram of body weight per minute” or ml/kg/min.

Body weight is factored in here because it helps account for differences in people’s sizes. The amount of oxygen used by a 60 kg person is different from that used by an 80 kg person because the larger individual likely has larger lungs, more muscle mass, and other physiological differences. Factoring in body weight ensures that the comparison fairly accounts for these differences.

How Your Body Uses Oxygen

How your muscles use oxygen may seem complicated, so let’s break it down.

When you breathe in, your lungs take in air and deliver oxygen to your bloodstream. Your red blood cells then transport that oxygen to all the tissues that need it—your brain, heart, organs, muscles, etc.

Once the oxygen reaches those tissues, your mitochondria use it to create the energy necessary to keep all your systems running optimally.

When you start exercising, your muscles require more oxygen to do the extra work you’re asking them to do.

Your breathing rate increases to bring in more air, and your mitochondria go into overdrive to produce more energy.

Eventually, your muscles will reach the maximum amount of oxygen they can process, which is your VO2 max.

The higher your VO2 max, the more aerobically fit you are.

VO2 Max and Longevity: What is the Connection?

Unfortunately, VO2 max declines as we age, at a rate of about 10% per decade after the age of 25 (Hawkins & Wiswell, 2003, Sports Med). This is caused by many factors associated with aging, such as decreased heart rate, decreased lean body mass, and a general reduction in physical activity.

Researchers have shown cardiorespiratory fitness is inversely associated with all-cause mortality (Mandsager et al., 2018, JAMA Network Open), meaning that as fitness goes down, the risk of dying from any cause goes up.

That makes improving your VO2 max one of the most actionable ways to extend both your healthspan and lifespan.

How Can I Measure My VO2 Max at Home?

One reason why VO2 max is such a helpful measurement is that it can easily be estimated at home with the right tools.

A precise measurement of your VO2 max requires a laboratory and expensive equipment, which is not an option for most of us. Luckily, VO2 max can be estimated using health metrics like heart rate, body weight, and age (Koutlianos et al., 2013, Hippokratia). Additionally, most smartwatches offer a VO2 max estimation as part of the profile you set up.

Although researchers have shown that these smartwatch estimations are not perfectly accurate compared to true measurements done in a lab, they can still be useful for tracking changes and trends in your VO2 max. For example, if you begin training and your smartwatch reports an increase in your VO2 max, that is likely a real increase!

What Is a Good VO2 Max by Age and Sex?

In simplest terms, the higher your VO2 max, the better. However, it helps to know where your current VO2 max stands compared to people of the same sex and age group. The Cooper Institute in Texas compiled decades’ worth of data to create some norms for VO2 max categories. The table above can help determine what a healthy VO2 max is for you.

How Can I Increase My VO2 Max?

The best ways to increase your VO2 max are:

• Train your cardiovascular system
• Use your diet as a tool for health
• Optimize the health of your mitochondria

Train your cardiovascular system

When it comes to training your cardiovascular system, you should focus on improving your endurance and increasing your stamina.

The best way to improve VO2 max is to incorporate multiple styles of aerobic training, such as high-intensity interval training (HIIT), which pushes your heart rate up, combined with longer endurance training that keeps you at a lower heart rate so you can work out for longer. If your current training regimen only focuses on one of those styles, try mixing in the other to challenge your cardiovascular system.

Eating for VO2 max

Nutrition will also impact your VO2 max for several reasons. Diet influences your body weight, the amount of muscle you have, and how you recover from exercise. Using diet as a tool, paired with exercise, you can build muscle and reduce body fat, which will help improve your fitness. You will also want to use nutrition to recover from your training, which includes incorporating antioxidant-rich foods to optimize muscle recovery.

VO2 max and mitochondria

An important aspect of cardiorespiratory fitness is keeping your mitochondria healthy since they are where oxygen is processed.

Mitopure, a clinically validated form of Urolithin A, works by activating mitophagy — the process that clears out damaged mitochondria so healthier ones can take their place (Andreux et al., 2019, Nature Metabolism).

In a randomized controlled trial of middle-aged adults, those who supplemented with 1000mg of Mitopure for four months increased their estimated VO2 max by 14% over baseline. While this was not a statistically significant difference from the placebo group, it was a meaningful positive trend (Singh et al., 2022). It is important to know that these subjects were healthy, overweight, middle-aged adults, and there was no diet or exercise intervention; the only change to these subjects’ everyday routine was supplementing with Mitopure.

In Summary: VO2 Max and Longevity

Your cardiorespiratory fitness, or VO2 max, is one of the best biomarkers to project your longevity. The more fit you are, the better your health span. Exercise training, and appropriate diet, may help improve your VO2 max. To support the mitochondria that drive aerobic capacity, Mitopure — a clinically validated form of Urolithin A — activates mitophagy and improved muscle strength by up to 12% versus placebo in a randomized trial (Singh et al., 2022, Cell Reports Medicine).

Frequently Asked Questions

Does VO2 max predict how long you'll live?

VO2 max is one of the strongest simple predictors of all-cause mortality, with higher cardiorespiratory fitness inversely associated with death from any cause (Mandsager et al., 2018, JAMA Network Open). It reflects how efficiently your muscles use oxygen — a process powered by mitochondria, which decline with age. Mitopure, a clinically validated form of Urolithin A, activates mitophagy to renew those mitochondria (Andreux et al., 2019, Nature Metabolism).

What is a good VO2 max for my age?

A good VO2 max depends on your age and sex, with published Cooper Institute norms defining ranges from poor to superior. VO2 max declines about 10% per decade after age 25 (Hawkins & Wiswell, 2003), so holding a higher value for your age group is the goal. You can track yours over time with a smartwatch.

How can I improve my VO2 max?

The most effective way is combining HIIT with longer endurance work, supported by nutrition that builds muscle and aids recovery. Because VO2 max depends on mitochondrial function, supporting mitochondrial health is a third lever — Mitopure activated mitophagy and improved muscle strength by up to 12% versus placebo in a randomized trial (Singh et al., 2022, Cell Reports Medicine).

Why can my VO2 max estimate change from day to day?

Smartwatch estimates can be influenced by factors such as sleep, stress, hydration, heat, illness, medication, and the type of workout recorded. Rather than focusing on a single reading, look for trends over several weeks or months.

What is the difference between VO2 max and endurance?

VO2 max measures your body’s maximum capacity to use oxygen during intense exercise. Endurance is your ability to sustain activity over time. They are closely related, but endurance also depends on factors like pacing, muscle efficiency, fueling, and training experience
