VO₂ Max Testing
Because “Guessing” isn’t a strategy
What Is VO₂ Max & Why It Matters
VO₂ max measures the maximum amount of oxygen your body can use during exercise. It reflects how efficiently your heart, lungs, muscles, and nervous system work together — and it’s one of the most powerful indicators of cardiovascular fitness, endurance capacity, and long-term health.
At Oz Wellness, VO₂ max testing removes the guesswork. Instead of relying on age-based formulas or generic training advice, we gather precise, individualized data that helps define your true aerobic capacity, training zones, and recovery needs.
Testing is performed in partnership with Salt Health using clinical-grade technology, providing a clear baseline for improving performance, resilience, and longevity — whether your goal is athletic optimization or simply aging well with energy and confidence.

FAQs
What is a VO₂ max test?
A VO₂ max test measures the maximum amount of oxygen your body can use during exercise. It is one of the most accurate indicators of cardiovascular fitness, aerobic capacity, and endurance.
Why is VO₂ max important?
VO₂ max provides insight into heart, lung, and muscle efficiency. Higher VO₂ max values are associated with improved endurance, better metabolic health, and reduced risk of cardiovascular disease.
How is the VO₂ max test performed?
The test is performed while you exercise—typically on a treadmill or stationary bike—while wearing a mask that measures oxygen intake and carbon dioxide output. Intensity increases gradually until you reach maximal effort.
How long does the test take?
The active test usually lasts 8–15 minutes, depending on fitness level. Including setup, warm-up, and recovery, plan for approximately 45–60 minutes total.
Do I need to prepare for the test?
Yes. You should avoid heavy meals, caffeine, alcohol, and intense exercise for several hours prior to testing. Wear comfortable athletic clothing and shoes. Specific preparation guidelines will be provided before your appointment.
Is VO₂ max testing safe?
For most individuals, VO₂ max testing is safe when performed by trained professionals using appropriate screening protocols. If you have known cardiovascular, respiratory, or metabolic conditions, medical clearance may be required.
Who should consider a VO₂ max test?
VO₂ max testing is beneficial for athletes, active individuals, and anyone interested in optimizing cardiovascular health, training efficiency, or longevity. It is also useful for tracking fitness improvements over time.
What information will I receive from my results?
You will receive your VO₂ max score along with data such as heart-rate zones, aerobic thresholds, and personalized insights to guide training, recovery, and overall wellness.
How often should VO₂ max be tested?
Most people benefit from testing every 3–6 months, depending on training goals. Regular testing helps track progress, adjust programming, and measure the effectiveness of lifestyle or fitness changes.
Will the test push me to my absolute limit?
The test is designed to reach maximal or near-maximal effort, but it is closely monitored and can be stopped at any time. Your safety and comfort are prioritized throughout the process.
