Exercise testing · Brussels

The VO2max test in Brussels.

VO₂max is your maximal oxygen uptake, the best indicator of your cardio-respiratory fitness. At the CIRCAE centre in Woluwe-Saint-Lambert (Brussels), the exercise test measures your VO₂max, determines your training thresholds (VT1/VT2) and checks that exercise is safe with an ECG.

Why do a VO2max test?

Our approach

Hard data, a concrete plan

·

Assess actual cardio-respiratory capacity

·

Define personalised training zones

·

Resume sport or intensify exercise safely

·

Prevent injuries and restore confidence in exercise

Understanding

What is VO2max?

VO₂max (maximal oxygen uptake) is the maximum amount of oxygen your body can use during intense exercise. It is the reference indicator of endurance and cardio-respiratory health: the higher it is, the better your ability to sustain effort. It is measured during a progressive exercise test, on a treadmill or bike, with a mask analysing expired gases.

Beyond the figure, the test identifies your ventilatory thresholds (VT1 and VT2): these define precise training zones (endurance, threshold, intensity) so you can progress effectively, without overtraining or injury.

The test

What the exercise test measures

A complete, medically supervised assessment, in a single session.

VO₂max & thresholds

Gas analysis

Measurement of maximal oxygen uptake and determination of VT1/VT2 thresholds, the basis of your personalised training zones.

Exercise ECG & safety

Cardiac

Monitoring of the ECG, heart rate and blood pressure during exercise to confirm cardiovascular safety.

Training plan

Sports physician

From the results, an individualised plan to return to sport, progress or prepare for a competition.

The process

A progressive assessment

The test is part of a progressive analysis of your ability to exert yourself and to recover, leading to an individualised programme. See the CIRCAMOVE movement assessment →

First exercise consultation

Consultation · Doctor + Physiotherapist

A meeting with two exercise experts to assess the type of problem, your goals and the need for an in-depth assessment.

  • Analysis of the main complaint (fatigue, pain, breathlessness, decline in performance)
  • Assessment of current and past physical activity levels
  • Medical and sporting history
  • Identification of barriers to movement
  • Definition of the examinations needed for a safe assessment

Musculoskeletal assessment

Functional assessment · Physiotherapist (30 min)

A comprehensive analysis of musculoskeletal function and movement quality.

  • Posture, joint mobility and flexibility
  • Muscle strength and motor coordination
  • Detection of imbalances and injury risk factors
  • Adaptation of the programme to actual capabilities

Multi-frequency bioimpedance

Body composition · Fasting

A precise measurement of body composition, ideally carried out while fasting, going well beyond weight alone.

  • Lean mass (muscle) and fat mass
  • Segmental distribution and body hydration
  • Objective monitoring of the effects of reconditioning
  • Adaptation of nutrition and physical activity

Cardio-respiratory exercise test with VO₂max

Cardiopulmonary exercise testing · Gold-standard examination

The gold-standard examination for analysing how the heart, lungs and muscles work together during exercise. VO₂max is now recognised as one of the best indicators of overall health.

  • VO₂max, ventilatory thresholds VT1 and VT2
  • Maximal aerobic power (MAP) and speed (MAS)
  • Ventilatory, cardio-circulatory or muscular limitations
  • Continuous monitoring: breathing, HR, blood pressure, perceived exertion

Resting and exercise metabolic assessment (LIPOXmax)

Metabolism · ±1h30

An in-depth analysis of metabolic function at rest and during exercise. It identifies the crossover point between fat and carbohydrate burning.

  • Measurement of basal metabolism by indirect calorimetry (30 min, fasting)
  • Exercise test with respiratory gas analysis (±45 min)
  • LIPOXmax: maximal fat oxidation capacity
  • Consultation with a specialist doctor

Why?

  • Precisely tailor the intensity of physical activity
  • Optimise nutrition and promote fat loss
  • Improve metabolic efficiency

Personalised reconditioning programme

Support · Doctor + Physiotherapist

Based on all the results, an individualised programme is built jointly by the doctor and the physiotherapist.

  • Tailored to the medical or sporting context
  • Based on actual ventilatory thresholds
  • Progressive, realistic and easy to fit into daily life
  • Improvement in endurance, strength and recovery
