Benefits of a VO2 Max Test

Cardiovascular fitness

Measure the maximum amount of oxygen your body can use during exercise, the core marker of aerobic fitness and cardiorespiratory capacity.

A proven longevity marker

VO2 max is one of the strongest predictors of all-cause mortality risk, a real, research-backed longevity marker, not just a fitness stat.

Personalized training zones

Get precise heart-rate training zones and fat-burning cardio zones, so every workout is built around your actual physiology instead of guesswork.

Smarter insights for athletes and everyday trainers

Whether you're training or just want to move better day to day, your VO2 max test results show exactly where your cardiovascular ceiling is, so you can identify weaknesses, avoid overtraining, and build a program that actually improves performance.

Aerobic and anaerobic thresholds

Know exactly where your body shifts from fat-burning to high-intensity effort, key data for smarter, more efficient endurance training.

Trackable fitness score

Retest your VO2 max score to see your cardiovascular fitness and longevity marker improve over time, with real data behind every gain.

FAQ

Good to know

What is a VO2 max test?

A VO2 max test measures the maximum amount of oxygen your body can use during intense exercise, making it the gold-standard indicator of cardiovascular fitness and aerobic capacity.

Is a VO2 max test only for athletes?

No. While athletes use it to fine-tune performance, VO2 max is one of the best overall indicators of cardiovascular fitness and longevity, making it valuable for anyone focused on long-term health.

How much does a VO2 max test in NYC cost?

A VO2 max test at Prefusion Health costs $199, and results are reviewed in person the same visit, including your personalized training zones.

What does a VO2 max test involve?

It's a guided treadmill or bike test where you wear a mask that measures your oxygen intake and CO2 output as effort gradually increases to your maximum capacity, coached by our team the entire time.

How do I prepare for a VO2 max test?

Do not train on the day of your test so you arrive fresh. Eat a small meal two to three hours before (not a full stomach), arrive normally hydrated, and bring athletic shoes and clothes you can genuinely push hard in.

Why does VO2 max matter for longevity?

Research consistently links higher cardiorespiratory fitness with lower all-cause mortality risk, making VO2 max one of the most meaningful, research-backed longevity markers you can measure.

How is a VO2 max test different from a smartwatch estimate?

A smartwatch estimates VO2 max using heart rate algorithms, which can be inaccurate. A clinical VO2 max test in NYC directly measures your oxygen consumption and CO2 output for a precise score.

What do I get from a VO2 max test besides a score?

You get personalized heart-rate training zones, fat oxidation zones, and clear aerobic and anaerobic thresholds, so you know exactly how to train, not just where you currently stand.

How often should I retest my VO2 max?

Every 90 days is a strong cadence if you're actively training, giving your body enough time to adapt and show measurable improvement in your fitness and longevity marker.

Before you come in

How to prepare for your VO2 max test

This one is a hard effort. Turning up in the right state is most of the result.

Do not train that day

This is a maximal effort test. Arrive fresh or you will not reach your true ceiling.

Eat lightly, not heavily

A small meal two to three hours before is ideal. Do not come on a full stomach.

Bring training kit

Sneakers and clothes you can genuinely push hard in.

Arrive normally hydrated

Not dehydrated, not loaded up on water. Both distort body-composition readings.
