VO₂ Max – Your Longevity Compass
When it comes to measuring health and predicting longevity, one metric stands out above all others: VO₂ max. This is the maximum amount of oxygen your body can use during exercise – a direct reflection of cardiovascular fitness, metabolic efficiency, and overall resilience. Research consistently shows that VO₂ max is the single strongest predictor of long-term health and survival, often more powerful than blood pressure, cholesterol, or even body weight.
At The Re:PAIR Clinic, we believe VO₂ max should be seen as your personal longevity compass. By knowing your number, you can take meaningful steps to optimise your healthspan and performance.
How We Measure VO₂ Max
We offer two complementary pathways for assessing VO₂ max, depending on your needs and preferences:
-
Formal VO₂ Max Testing (Laboratory Referral)
A gold-standard treadmill or cycle ergometer test, with real-time gas exchange analysis. This provides the most precise measurement of your VO₂ max, along with detailed insights into your aerobic threshold, efficiency, and recovery profile. -
Chester Step Test (In-Clinic at The Re:PAIR Clinic)
A validated, practical alternative suitable for most people. This submaximal test uses heart rate response to stepping exercise to reliably estimate VO₂ max without the need for a lab environment. It’s safe, repeatable, and gives a clear picture of your aerobic fitness trajectory over time.
Why VO₂ Max Matters
-
The strongest predictor of longevity – higher VO₂ max levels are directly linked to lower all-cause mortality.
-
A window into your healthspan – it reflects not only fitness but also mitochondrial function, vascular health, and resilience against chronic disease.
-
Actionable and trainable – unlike genetics or age, VO₂ max is something you can actively improve through personalised training and recovery strategies.
