More insight into your energy expenditure.

A metabolic test measures your respiratory gases at rest, during exercise or with both types of test combined. A possible starting point for focused questions about nutrition, movement and training. Available separately or, where appropriate, as part of a personal programme.

The measurement in pictures

Your breathing tells a story.
We help you understand it.

A measurement at rest or during exercise provides different information. We choose the form that fits your question and capacity for activity.

Two drawn testing situations: a resting test with a breathing mask in a chair on the left, and a supervised cycling test with a breathing mask on the right.
Left: testing at rest. Right: testing during exercise. The mask collects information about your breathing; this is not an oxygen treatment.
At rest

Your energy expenditure.

Using oxygen uptake and carbon dioxide output, we estimate how much energy your body uses at rest. You receive instructions beforehand to make the measurement as reliable as possible.

During exercise

Your response to movement.

As the exercise level changes, we measure your respiratory gases. The chosen test and your capacity for activity determine the information we can collect.

The result

From numbers to insight.

We discuss the results in relation to your question about nutrition, movement or training. A measurement alone does not explain every cause of fatigue.

Illustrative testing situations. The procedure and equipment may differ. An exercise test is not suitable for everyone.

TWO WAYS TO MEASURE

At rest.
During exercise.
Or both.

During a resting test, you sit or lie comfortably. During an exercise test, your breathing is measured while you move.

You can also combine both types of test. The appropriate form depends on your question and capacity for activity. We discuss the choice and preparation beforehand.

At rest: understand your resting energy expenditure

You breathe through a mask while sitting or lying quietly. Resting energy expenditure is calculated from measured oxygen uptake and carbon dioxide output. This can help tailor nutritional advice.

Resting energy expenditure is not the same as your total daily energy requirement. Movement and other daily activities add to it. The measurement also does not show how energetic you subjectively feel.

During exercise: insight into your response to exertion

During supervised exercise, we measure how your oxygen uptake and breathing change. Depending on the protocol and measurement quality, the data may help tailor training intensity.

A resting test does not determine maximal oxygen uptake. A suitable exercise test is required to assess peak or maximal oxygen uptake. Our respiratory gas analysis is not automatically equivalent to a full medical cardiopulmonary exercise test; referral may be needed for a medical diagnostic question.

A baseline measurement with a clear question

We discuss what you want to know beforehand and whether the test can answer it. For example, resting energy expenditure as a basis for nutritional guidance, or your response to exercise as part of a training plan.

  • An explanation of preparation, test type and costs beforehand.
  • Assessment of suitability and capacity for activity.
  • A report with the results; choose an option with a personal evaluation if desired.
  • A repeat measurement only if it helps answer a specific question.

What does the test not tell you?

The test alone does not establish the cause of fatigue, sleep problems or long COVID. Nor does it predict whether IHHT, NESA or red light will work for you. Results depend on preparation, recent food intake and exercise, measurement conditions and the protocol, among other factors.

Which test suits you?

An exercise test is not suitable for everyone. Where there are symptoms, a medical history or worsening after exertion, we first discuss whether and how testing is appropriate. With long COVID and PEM/PESE, an exercise test is not a standard component. You receive personal preparation instructions beforehand.

Prices: one test or both together

Choose a resting test (RMR), exercise test (AMR) or both. Every option includes a report. A personal evaluation is included in the options that state this.

  • Rest OR exercise + report: €160.
  • Rest AND exercise + report: €210.
  • Rest OR exercise + report + evaluation: €250.
  • Rest AND exercise + report + evaluation: €300.

Choose separately. Or as part of your programme.

You can have the test without a treatment programme. If a baseline measurement is included in your programme, your proposal specifies which test, report and any evaluation are included. A repeat measurement or second type of test is not automatically included.

A measurement is a tool for a specific question, not a compulsory step for every visitor. We discuss beforehand what the result could add.
