If you care about living longer and living better, VO₂ max belongs at the top of your dashboard.

At NuVitale in Suwanee, we take VO₂ max out of the abstract and turn it into actionable training. We pair lab-grade testing with DEXA body composition, PNOE metabolic analysis, movement screening, and a coordinated plan across cardio, strength, recovery, and nutrition.

We do not guess, we test—then we program.

Whether you are an athlete chasing performance or simply want more energy and a longer, healthier life, understanding your VO₂ max can dramatically improve your healthspan.



Here is how VO₂ max works, what a good score looks like, how often to retest, and how we integrate your data into one clear, results-focused plan.

What VO₂ Max Measures — and Why It Matters

VO₂ max is the maximum rate at which your body can take in, transport, and use oxygen during intense exercise.

It is typically measured in milliliters of oxygen per kilogram of body weight per minute (mL/kg/min).

A higher VO₂ max is associated with:

• Lower all-cause mortality risk
• Better cardiovascular fitness
• Improved mitochondrial function
• Greater work capacity

Longevity experts such as Peter Attia and Andrew Huberman emphasize VO₂ max because it is:

• Trainable throughout life
• Predictive of endurance and resilience
• A practical metric that guides heart-rate zones, intervals, and recovery



A single number never tells the entire story, but it provides a powerful foundation for lifelong health.

How VO₂ Max Is Tested

Gold-standard testing uses a graded exercise test performed on either:

• A treadmill
• A cycle ergometer

while a metabolic cart measures oxygen consumption and carbon dioxide production breath by breath.



At NuVitale, clinician-supervised PNOE protocols gradually increase speed or resistance until maximal effort is reached.

Throughout testing we monitor:

• Heart rate
• Ventilatory thresholds
• Respiratory Exchange Ratio (RER)
• Perceived exertion

to accurately determine your training zones.

Before Your Test

• Arrive well hydrated.
• Avoid heavy meals for 2–3 hours beforehand.
• Avoid strenuous exercise for 24 hours before testing.
• Bring running or cycling shoes.
• Bring any prescribed inhalers.
• Bring a current medication list.

Most visits last 45–60 minutes, including setup, testing, and an initial review of results.

Many patients combine VO₂ Max testing with DEXA and resting metabolic testing during one appointment.

Inside PNOE: 23 Biomarkers From a Single Breath

PNOE is a clinical-grade cardiometabolic analyzer that measures 23 biomarkers using approximately ten minutes of breathing through a mask.

No blood draw.

No laboratory wait.

Using indirect calorimetry, PNOE measures oxygen consumption and carbon dioxide production breath by breath to evaluate how oxygen moves through your lungs, heart, and cells.

The biomarkers fall into four major categories.

Pulmonary & Respiratory Function

Measures include:

• Breathing frequency
• Tidal volume
• Minute ventilation
• Forced expired volume
• Ventilatory efficiency (VE/VCO₂)
• End-tidal CO₂ and O₂
• Expired gas fractions

These measurements reveal how efficiently you exchange oxygen and carbon dioxide.

Cardiovascular & Circulatory Health

Evaluates:

• Heart rate
• Heart Rate Variability (HRV)
• O₂ pulse
• Oxygen-to-breathing-frequency ratio

O₂ pulse provides insight into how much oxygen your heart delivers with each beat.

Metabolic Function & Energy Use

Measures include:

• VO₂ Peak (VO₂ Max)
• Carbon dioxide production
• Respiratory Exchange Ratio (RER)
• Total calorie expenditure
• Fat oxidation
• Carbohydrate oxidation
• Mechanical efficiency
• Crossover point (when the body shifts from primarily burning fat to carbohydrates)

Performance & Threshold Markers

PNOE determines:

• Aerobic threshold
• Anaerobic threshold

These measurements establish personalized training zones rather than relying on generic age-based formulas.

One ten-minute breath test. Twenty-three biomarkers. The difference between guessing your zones and knowing them.

Your Five Training Zones — and Your Fat-Burn Sweet Spot

Most heart-rate calculators estimate zones using formulas such as:

220 − age

The problem is that these formulas often miss your true physiology.

PNOE directly measures your thresholds and crossover point, allowing training to match your metabolism.

Zone 1 — Recovery

Easy conversational effort.

Primary goal:

• Recovery
• Blood flow

Fuel source:

• Mostly fat

Zone 2 — Aerobic Base & Fat Burning

Often considered the longevity zone.

Benefits include:

• Improved mitochondrial density
• Better metabolic flexibility
• Maximum fat oxidation

Zone 3 — Tempo

Moderately difficult effort.

Fuel gradually shifts toward carbohydrates.

Zone 4 — Threshold

Built around your measured anaerobic threshold.

Improves the pace or power you can sustain over time.

Zone 5 — VO₂ Max

Short, high-intensity intervals designed to increase your maximum aerobic capacity.

FatMax and the Crossover Point

One of the most valuable outcomes of PNOE testing is identifying:

• FatMax
• Your crossover point

The crossover point is where your body transitions from primarily burning fat to primarily burning carbohydrates.

Knowing this allows clinicians to prescribe the exact heart rate or pace that maximizes fat burning.

For weight loss:

• Better fat oxidation
• Improved metabolic flexibility

For athletes:

• Higher endurance
• Improved threshold performance
• Better fuel utilization

Rather than using generalized charts, your program is built around your actual physiology.

What Is a Good VO₂ Max?

VO₂ Max varies according to:

• Age
• Sex
• Sport
• Training history
• Altitude

General reference ranges include:

Recreationally Active Adults

• Men: Mid-30s to low-40s mL/kg/min
• Women: High-20s to mid-30s

Trained Endurance Athletes

• Men: 50s–60s
• Women: 40s–50s

Elite Athletes

• Men: Above 70
• Women: Above 60

Reported examples include:

• Lance Armstrong: Mid-to-high 80s
• Michael Phelps: Approximately 50s to low 60s

Your individual progress over time is more important than comparisons with others.

Are Wearables Accurate?

Devices such as the Apple Watch estimate VO₂ Max using:

• Heart rate
• Pace
• Algorithms

They can be useful for tracking trends.

However, wearable estimates cannot accurately determine:

• Ventilatory thresholds
• Fat-burning zones
• Individualized training prescriptions



Laboratory testing remains the gold standard for precision.
