VO2 max is more than a fitness metric — it is one of the most meaningful measures of how efficiently your body performs during exercise, and one of the strongest predictors of long-term health. Whether you are a data-driven athlete tracking performance or someone focused on living a longer, healthier life, understanding your VO2 max score gives you an actionable baseline and a clear target to train toward.
At BeFit Training Physiotherapy, VO2 max testing is available at both our Edgecliff and Coogee clinics as part of our Assessments and Testing service.
What VO2 Max Actually Measures
VO2 max is measured in millilitres of oxygen per kilogram of body weight per minute (ml/kg/min). This number represents the maximum volume of oxygen your body can utilise during intense exercise. During high-intensity effort, your body needs to produce ATP — adenosine triphosphate — the energy currency that powers muscle contractions. Your VO2 max score reflects how efficiently the lungs, heart, blood vessels, and muscles work together to make that happen.
The lungs extract oxygen from the air into the bloodstream. The heart pumps oxygenated blood to working muscles. The blood vessels transport oxygen via red blood cells. The muscles use that oxygen within their mitochondria to produce energy. The higher your VO2 max, the more efficiently this entire system operates — and the greater your capacity for sustained physical effort.
Why VO2 Max Matters for Long-Term Health
VO2 max is not only a performance metric for athletes. Research consistently identifies cardiorespiratory fitness as one of the strongest independent predictors of mortality risk. A landmark analysis of over 122,000 patients published in JAMA Network Open by Mandsager et al. (2018) found that individuals with elite levels of cardiovascular fitness had an 80 percent lower mortality risk compared to the least fit group — a differential larger than that seen for most established cardiovascular risk factors. There was no observed ceiling to the benefit of higher fitness.
Understanding your VO2 max score helps you set realistic fitness goals, tailor your training, and track meaningful progress over time. It provides an objective baseline rather than a subjective sense of how fit you feel.
VO2 Max Norms by Age and Sex
The table below provides population reference ranges for VO2 max by age group and sex. These norms help contextualise where your score sits relative to your peers and inform appropriate training targets.

How to Use Your VO2 Max Score
Understanding where your score sits relative to population norms helps you know your current baseline, set realistic and meaningful goals, track progress over time, and identify where your training may benefit from greater focus. Your VO2 max score tells you the right mix of training intensities for optimal cardiovascular development and gives you an objective, trackable number that goes well beyond how you feel on any given day.
Common Questions About VO2 Max Testing
How is VO2 max tested at BeFit?
VO2 max testing at BeFit is conducted at our Edgecliff and Coogee clinics using a graded exercise protocol. You wear a metabolic mask that measures the concentration of oxygen and carbon dioxide in your breath during progressive exercise intensity. The test identifies the point at which your oxygen consumption plateaus — your VO2 max — and provides an objective measure of your cardiovascular fitness capacity.
Who should get a VO2 max test?
VO2 max testing is relevant for anyone who wants an objective measure of their cardiovascular fitness — whether that is an athlete tracking performance, someone managing a chronic health condition, or a person focused on longevity and healthy ageing. It is particularly useful when combined with a broader health and performance assessment, such as the programme offered through BeFit’s partnership with Everlab.
How can I improve my VO2 max?
VO2 max is highly trainable. The most effective strategies include sustained aerobic training at moderate intensity, high-intensity interval training, and progressive increases in training volume over time. Your VO2 max test result provides the data needed to structure training zones precisely rather than training by feel alone.
Is VO2 max testing safe?
Yes. VO2 max testing involves progressive exercise to a maximal or near-maximal effort and is conducted under supervision at our Edgecliff and Coogee clinics. If you have any cardiovascular conditions or health concerns, discuss these with your physiotherapist before booking so that the appropriate protocol can be selected for your situation.
Do I need a referral to book a VO2 max test at BeFit?
No referral is required. VO2 max testing is available at both our Edgecliff and Coogee clinics and can be booked directly.
