The Worldwide Metabolic Testing Atlas

The Mera Atlas brings together performance, clinical and academic testing facilities identified and reviewed from public sources across 100+ countries. Browse the country directory to see where VO₂max, CPET, lactate and other physiological testing are available.

Use these methods to compare the services offered by performance laboratories, university labs and clinical testing facilities in the Atlas.

VO₂max / CPET

Measures maximal oxygen uptake and the cardiovascular, respiratory and metabolic response during exercise.

Lactate

Uses blood lactate samples during an exercise protocol to identify intensity transitions and training zones.

SmO₂

Uses near-infrared spectroscopy to monitor local muscle oxygen saturation during exercise.

RMR

Measures resting oxygen consumption and carbon dioxide production to estimate resting energy expenditure.

Sweat

Measures sweat rate and, where available, sodium or electrolyte concentration during exercise.

DEXA

Uses low-dose X-ray assessment to measure body composition and bone mineral density.

Hypoxia / Altitude

Assesses or trains physiological responses under reduced-oxygen or simulated-altitude conditions.

Blood gases

Measures oxygen, carbon dioxide, pH and related values in arterial or capillary blood.

BOD POD

Uses air-displacement plethysmography to estimate body composition.

FatMax

Identifies the exercise intensity associated with the highest measured fat oxidation.

ECG

Records the electrical activity of the heart at rest or during exercise.

Wingate

A short maximal cycling test used to assess anaerobic power and fatigue.

Isokinetic

Measures muscle strength and balance at a controlled movement speed.

Heat chamber

Tests or trains athletes in controlled hot and humid environmental conditions.

We include a facility when a public source confirms VO₂max, CPET, lactate, gas analysis or another relevant physiological testing service. DEXA-only and imaging-only facilities are not included in the metabolic testing directory.

If a laboratory is missing or its information has changed, send us the details and a direct service or laboratory link through the Atlas submission form.

We are open to collaborations ranging from a free pilot to commercial cooperation. Mera partners are highlighted on the map and shown first in location results. Let's build the future of human performance together.

Yes. Search by location, then refine the map with testing methods, sports, equipment and organization type. Partner facilities are surfaced first in the location list.

No. We list DEXA or body-composition services when metabolic or physiological testing is also confirmed by a public source; imaging-only facilities are kept out of the Atlas.
