It all starts with understanding your context and goals: that's what shapes the exercise-test protocol, which measures how your body transforms and manages energy. But measurement is only the starting point: the raw data is then processed and analysed with the most appropriate techniques, in line with the current state of the art. Twin Peak Lab also draws on models of muscle energy metabolism to enrich the profile. It's this full process that reveals your physiological and metabolic ID card — your unique signature.
From your context and goals to your physiological and metabolic ID card. The testing, the science and the deliverable are one coherent process — which then carries on, seamlessly, into the application.
You tell us your discipline, your context and what you're looking for. That's what shapes the protocol : tailor-made, focused on what we actually want to measure — never a one-size-fits-all test.
Running the appropriate protocol — blood lactate and/or gas exchange — under standardised, rigorous conditions. This is where your raw measurements are collected.
Your raw measurements are analysed with recognised methodologies and models of muscle energy metabolism. This is the step that turns data into meaning — your thresholds, your zones, your energy capacities — from your own data, never from population averages.
We hand back your physiological and metabolic signature : individualised thresholds and zones, a reading of your energy metabolism and concrete benchmarks to calibrate your training. This is the culmination of profiling.
Your ID card doesn't stay on paper. It feeds straight into the Twin Peak Lab application, where you explore and use it day to day to calibrate your sessions and track your progress. Profiling and application are one integrated whole.
Profiling rests on two main families of measurements : blood lactate and gas exchange. Depending on what you want to measure and estimate, we use one, the other, or both combined, with the right protocol.
We measure how your blood lactate concentration changes at key moments — and your heart rate continuously — during a progressive step exercise test, always tailored to your sport. The result : identification of your lactate thresholds, transitions and individualised intensity zones.
We continuously measure, breath by breath, the oxygen (O₂) you take in and the carbon dioxide (CO₂) you breathe out — along with your heart rate — during a progressive exercise test that typically combines a ramp and steps, always tailored to your sport. The result : identification of your ventilatory thresholds, transitions and individualised intensity zones, VO₂max (and associated MAS or MAP) and movement economy (metabolic cost).
To us, a measurement only matters if it's usable day to day. Benchmarks captured in conditions you never meet in training are of limited use : what counts is information that's reproducible, day after day, in your real context.
That's why we work mobile, with your own equipment — home trainer, bike, treadmill, athletics track — when you have it. The test then takes place in the very environment of your training : whether you're an athlete, coach, club, structure or federation, we measure where you make progress every day.
Don't have the right equipment ? The test can also be carried out at a partner centre certified by Twin Peak Lab.
Profiling is always individualised — and it doesn't stop at the test. For a very particular need or an ambitious project, Twin Peak Lab goes further : we study with you the protocols and measurement systems best suited to your goal, and we can build bespoke tools — specific data analyses, group analyses… — and develop new application features on demand. Tell us about your need and we'll discuss it together.
At the end of the test, you leave with far more than a single number :
True to our approach, we don't offer a single fixed-price package. The protocol and the measurements depend on the depth of profiling you're after — on what we actually want to measure and estimate. And access to the application — features, individual view or group view — is tailored to how you'll use it, particularly for coaches, clubs, structures and federations. Each proposal, and its price, is therefore set specifically, based on your request.
In every case, we're available for an initial, no-obligation conversation : we take the time to understand your context and your goals before suggesting the solution that fits best.
