Protocol

VO2max / cardiopulmonary exercise testing

VO2 max · VO2max testing · CPET · cardiopulmonary exercise testing · cardiorespiratory fitness testing · maximal oxygen uptake · exercise treadmill testing with gas exchange

Cardiorespiratory fitness is among the most robustly evidenced predictors of all-cause mortality in humans. A retrospective cohort of 122,007 adults undergoing exercise treadmill testing at the Cleveland Clinic (JAMA Network Open, 2018, median follow-up 8.4 years) found an inverse, graded relationship between fitness and mortality, with elite performers at an adjusted hazard ratio of 0.20 versus low performers and no observed upper limit of benefit. The 2016 American Heart Association scientific statement concluded that low CRF is associated with high cardiovascular and all-cause mortality risk, is potentially a stronger predictor than smoking, hypertension, dyslipidaemia or type 2 diabetes, and significantly improves risk reclassification. What this does NOT show: the evidence establishes fitness as a modifiable exposure and a prognostic marker, not that the act of measuring VO2max changes outcomes. There is no trial demonstrating that VO2max testing itself extends lifespan or healthspan; the causal arm of the evidence rests on exercise training trials, and no RCT randomises people to being tested. Clinic-quoted effect sizes (for example Everlab's "for every 10-point increase in VO2 Max, there is a 17 per cent lower risk of death from cancer and an 11 percent reduction in overall mortality") are observational associations presented without a cited source and should not be read as causal. VO2max is also effort-dependent and protocol-dependent, so values are not directly comparable across providers, and estimated (submaximal or wearable-derived) VO2max is a weaker measure than a true maximal test with gas exchange.

At a glance

Evidence
Clinical
Singapore (HSA)
Not applicable as a product registration. HSA regulates the import, manufacture, export and supply of medical devices as products, and does not regulate clinical procedures or services performed by clinicians, so a VO2max test carries no HSA approval status of its own. The metabolic cart and gas analyser hardware used to perform it falls within HSA's medical device remit as equipment, while the test itself is delivered as routine clinical physiology, offered in Singapore by NOVI Health as a paid add-on (SGD 250 with GST) performed at a partner clinic.
Australia (TGA)
Not a TGA-registered therapeutic good, because CPET is a clinical procedure rather than a product. It is delivered in Australia as established clinical exercise physiology, including by longevity clinics such as Everlab, which requires medical clearance for clients over 35. Caveat: repeated attempts to reach tga.gov.au during this research timed out, so the TGA-side framing (that the TGA regulates therapeutic goods, not clinical procedures, and that specific metabolic cart analysers are separately included on the ARTG as medical devices) could not be confirmed against a live TGA source and should be re-verified before publication.

Evidence is not approvalAn evidence grade describes how strong the science is. A regulatory status describes whether a body has approved the intervention for an indication. They are different questions, answered separately above.

What it is

Plain-language explainer

VO2max is the maximum rate at which the body can take up and use oxygen during progressively harder exercise, measured directly by breath-by-breath gas analysis during an incremental treadmill or cycle test taken to exhaustion. It is the standard quantitative measure of cardiorespiratory fitness and is used in longevity practice as a prognostic marker and as a baseline for prescribing training. Clinics position it as a predictor of long-term mortality risk and a way to track whether an exercise programme is working.

Common questions

What is VO2max / cardiopulmonary exercise testing?
Cardiorespiratory fitness is among the most robustly evidenced predictors of all-cause mortality in humans. A retrospective cohort of 122,007 adults undergoing exercise treadmill testing at the Cleveland Clinic (JAMA Network Open, 2018, median follow-up 8.4 years) found an inverse, graded relationship between fitness and mortality, with elite performers at an adjusted hazard ratio of 0.20 versus low performers and no observed upper limit of benefit. The 2016 American Heart Association scientific statement concluded that low CRF is associated with high cardiovascular and all-cause mortality risk, is potentially a stronger predictor than smoking, hypertension, dyslipidaemia or type 2 diabetes, and significantly improves risk reclassification. What this does NOT show: the evidence establishes fitness as a modifiable exposure and a prognostic marker, not that the act of measuring VO2max changes outcomes. There is no trial demonstrating that VO2max testing itself extends lifespan or healthspan; the causal arm of the evidence rests on exercise training trials, and no RCT randomises people to being tested. Clinic-quoted effect sizes (for example Everlab's "for every 10-point increase in VO2 Max, there is a 17 per cent lower risk of death from cancer and an 11 percent reduction in overall mortality") are observational associations presented without a cited source and should not be read as causal. VO2max is also effort-dependent and protocol-dependent, so values are not directly comparable across providers, and estimated (submaximal or wearable-derived) VO2max is a weaker measure than a true maximal test with gas exchange.
How strong is the evidence for VO2max / cardiopulmonary exercise testing?
Clinical. There is human trial evidence, which is the strongest grade variis applies to a protocol.
Is VO2max / cardiopulmonary exercise testing approved in Singapore?
Health Sciences Authority position on record: Not applicable as a product registration. HSA regulates the import, manufacture, export and supply of medical devices as products, and does not regulate clinical procedures or services performed by clinicians, so a VO2max test carries no HSA approval status of its own. The metabolic cart and gas analyser hardware used to perform it falls within HSA's medical device remit as equipment, while the test itself is delivered as routine clinical physiology, offered in Singapore by NOVI Health as a paid add-on (SGD 250 with GST) performed at a partner clinic.. An evidence grade and a regulatory approval are different questions.
Is VO2max / cardiopulmonary exercise testing approved in Australia?
Therapeutic Goods Administration position on record: Not a TGA-registered therapeutic good, because CPET is a clinical procedure rather than a product. It is delivered in Australia as established clinical exercise physiology, including by longevity clinics such as Everlab, which requires medical clearance for clients over 35. Caveat: repeated attempts to reach tga.gov.au during this research timed out, so the TGA-side framing (that the TGA regulates therapeutic goods, not clinical procedures, and that specific metabolic cart analysers are separately included on the ARTG as medical devices) could not be confirmed against a live TGA source and should be re-verified before publication.. An evidence grade and a regulatory approval are different questions.
