VO₂ Max Testing

VO₂ Max is your body’s fitness engine score.

It measures how much oxygen your body can take in, deliver to your muscles, and use during exercise. The higher your VO₂ Max, the more efficiently your heart, lungs, and muscles work together to produce energy. It is considered one of the best predictors of cardiovascular fitness, endurance performance, and even long-term health and longevity.

Why it matters:

Reveals your true fitness level
Identifies personalized heart rate training zones
Helps improve endurance and athletic performance
Tracks fitness progress over time
Provides insight into overall cardiovascular health

Simple analogy:

Think of VO₂ Max as the horsepower rating of your body. The more oxygen your body can use during exercise, the more work it can perform.

RMR tells you how many calories your body burns just to stay alive.

Even when you’re resting, your body is constantly using energy to breathe, pump blood, regulate temperature, fuel your brain, and maintain your organs. RMR measures the calories required to perform these essential functions. For most people, it accounts for about 60–70% of total daily calorie burn.

Why it matters:

Provides an accurate starting point for weight loss
Helps prevent under-eating or over-eating
Creates personalized calorie targets
Improves nutrition planning
Tracks metabolic changes over time

Simple analogy:

Think of RMR as your body’s idle fuel consumption. Just like a car burns fuel while sitting at a stoplight, your body burns calories 24 hours a day—even when you’re doing nothing.

VO₂ Max tells you how efficiently your body uses oxygen during exercise.

RMR tells you how many calories your body burns at rest.Together, they provide a complete picture of your fitness, metabolism, and health—allowing you to train smarter, fuel properly, and measure progress with real data instead of guesswork.

How to Improve Your VO2 Max to Help...

Does walking to the mailbox or up a short flight of stairs leave you winded? You may be experiencing a decline in VO2 max, and that number matters more than you might think.

VO2 max measures your body’s ability to absorb and use oxygen while exercising and is one of the strongest overall measures of cardiovascular fitness. It’s also a key marker of cardiorespiratory fitness and is linked to heart health, longevity and daily function.

VO2 max is among the most elusive terms in fitness. You may have heard of it, as it’s often heralded as the number that defines your cardiovascular fitness. Yet for many, the concept is confusing and misunderstood—a pinnacle of athletic prowess for elite endurance athletes, sure, but not for average folks without access to a performance lab. Well, this metric is still

How VO2 Max and Lactate Threshold Testing...

Most high school athletes, even at the global level, never have access to metabolic testing. At IMG Academy, it’s part of the program. Through the Gatorade Sports Science Institute, student-athletes undergo VO2 max testing and lactate threshold testing administered by on-campus scientists like Phil Agostinelli, giving coaches the data they need to build training programs around each athlete’s individual physiology.

This Is The Most Important Test For Brain ...

If you ask wellness experts to name the single most important test for brain longevity, you’d probably hear answers ranging from cognitive assessments, to genetic panels, to brain scans. But neurologist Majid Fotuhi, M.D., Ph.D., offered a different answer entirely in his conversation with mindbodygreen co-founder Jason Wachob at the 2026 Revitalize summit.

And you might be surprised to learn that it’s not a brain test at all. It’s a fitness metric.

“I think the most important test for brain longevity is VO2 max, which is a measure of your physical endurance,” Fotuhi said. “If you increase your physical endurance, your brain will be healthier.”
