Benefits of VO2 max testing

Aerobic capacity

Aerobic capacity

Your VO2 max and the real heart-rate zones that go with it, so cardio is aimed instead of guessed.

VO2 MAX
Fat-burning and threshold zones

Fat-burning and threshold zones

Where your body burns the most fat and where your threshold sits, so easy days and hard days are both aimed.

VO2 MAX
Supervised, start to finish

Supervised, start to finish

Ten to fifteen minutes on a bike or a treadmill, fully supervised, with your results read back to you before you leave.

VO2 MAX
After the test

VO2 max is the strongest single longevity marker we measure. So use it.

A number on a report changes nothing. Prefusion Health turns your VO2 max and your zones into training you can follow, and a retest shows it moving.

01
Your aerobic ceiling
Directly measured oxygen uptake, not a wearable's estimate from your heart rate and your age.
02
Real training zones
The heart rates where you actually burn fat and where you actually build threshold, specific to you.
03
A longevity marker you can move
Unlike most risk markers, this one responds to training within weeks, and a retest proves it.

Optional: the Optimization Pack adds a DEXA scan for body fat and lean mass and a resting metabolic rate test for your resting calorie burn, all three in one visit. Purchased separately.

Frequently asked questions

What is a VO2 Max test?
VO2 Max stands for maximal oxygen uptake, it measures how efficiently your body uses oxygen during exercise. It's considered the gold standard for assessing aerobic fitness and endurance capacity.
How does a VO2 Max test work?
A VO2 Max test in NYC involves performing graded exercise on a treadmill or bike while wearing a mask to measure oxygen intake and carbon dioxide output. The exercise intensity increases gradually until your body reaches its maximum oxygen consumption capacity.
Is VO2 Max testing safe?
Yes, the VO2 test in nyc is safe and non-invasive. The test is performed under controlled conditions by trained professionals using clinical-grade equipment to monitor your heart rate and breathing. We offer walking and running protocols, and the test can be conducted on either a treadmill or a stationary bike.
How long does a VO2 Max test in NYC take?
The VO2 Max test in nyc typically takes 30 - 40 minutes, including setup, warm-up, and the test itself, which lasts 10 - 15 minutes based on your fitness level.
Why VO2 Max Matters for Longevity?
In this 60 Minutes segment, Dr. Peter Attia explains why the VO2 Max test is one of the strongest predictors of lifespan, and how training in the right zones (steady Zone 2 plus weekly high-intensity) can move the needle. Watch to see what the VO2 Max testing actually measures, simple ways to estimate it, and why testing + retesting gives you a clear path to improve.
Can I do the VO2 Max test if I'm not familiar with it?
Yes, VO2 Max testing is suitable for beginners and experts alike. The test gradually increases in intensity, allowing you to work at your own pace. It can also be a great way to set a baseline for future improvements.
Can I improve my VO2 Max?
Yes, through regular aerobic exercise, particularly interval training and endurance work. Activities like running, cycling, and swimming can boost your VO2 Max test score by improving cardiovascular efficiency.
