VO₂ max measures the maximum amount of oxygen your body can take in, transport and use during exercise. It is one of the most relevant indicators of cardiorespiratory fitness, associated in numerous studies with cardiovascular health and longevity.

How the test works

Testing is carried out as a progressive exercise test, on a cycle ergometer or treadmill, under medical supervision. Using a mask and a respiratory gas analyser, we measure in real time oxygen consumption (O₂), carbon dioxide production (CO₂) and your body’s response as exercise intensity increases.

Unlike smartwatch estimates, this method directly measures respiratory gas exchange. We don’t estimate performance — we measure it.

What you learn at the end of the test

• VO₂ max – your maximum aerobic capacity, in ml/kg/min, relative to age and sex.
• Ventilatory thresholds VT1 and VT2 – the points at which your respiratory and metabolic response changes with intensity.
• Personalised training zones – calculated from your physiology, not from general formulas.
• Cardiovascular and respiratory response to exercise – heart rate, ventilation, oxygen consumption.
• A longevity benchmark – one you can track and improve through periodic testing.

Who it is useful for

• Sedentary people who want to start a physical activity programme.
• Active people who want to improve their endurance and cardiovascular fitness.
• Amateur and elite athletes optimising their training.
• People interested in prevention, longevity and maintaining functional capacity.

Testing is carried out after a medical assessment of fitness for exercise. Depending on the protocol and the level of effort reached, the result may represent VO₂ max or VO₂ peak. Testing does not replace a cardiology assessment when one is indicated.
