Your dynamic physiological and metabolic ID card

Individualising training and preparation is not optional: every individual has a unique physiological and metabolic signature. It's profiling that determines it: we adopt the measurement protocols and analyses that are most relevant scientifically, selected according to what we're seeking to define. One-size-fits-all methods make no sense, and we know it — only specifics, always tied to your inner workings and your context.

My approach

Understanding complex systems

For nearly twenty years, I've studied and modelled complex systems.

I first took part in work modelling the dynamics of the atmosphere of the planet Venus. I then completed a doctorate devoted to the numerical modelling of how the human heart works, in order to study certain mechanisms involved in cardiac rhythm disorders. I later spent more than a decade developing advanced models designed to represent the economic and financial environment within one of the largest insurance groups in Europe.

At first glance, these fields have nothing in common. Yet they all rest on the same foundations: understanding multidimensional systems, identifying the interactions between their components, and building models capable of representing a complex reality.

An athlete is a complex system too: dozens of variables interacting constantly, which no average can capture. That's the lens, and the models, I now bring to your performance.

The principle

Individualisation as the watchword

Optimising performance — and well-being more broadly — starts with understanding your inner workings. Twin Peak Lab identifies your unique physiological and metabolic signature — a true internal ID card: the basis for truly personalised training decisions. No averages, no generalities: your reality is what Twin Peak Lab takes as its anchor.

An integrated approach

Testing, science, application

Testing, combined with scientifically recognised analysis methodologies and powerful models, establishes your unique physiological and metabolic signature; the application then lets you explore it and put it to work day to day to optimise your performance and reach your sporting goals. From the test to today's session, everything is in one place — with no gap between the lab and the field.

1. The testing

An exercise-test protocol tailored to your goals and needs. Twin Peak Lab takes your context into account to offer you the most suitable solution: individualisation combined with scientific rigour.

2. The science

Analysis and modelling methodologies turn the raw measurements collected during testing into your unique physiological and metabolic signature — your internal ID card, built from your own data, never from population averages.

3. The application

Explore the characteristics of your physiological and metabolic signature dynamically in our Twin Peak Lab app and put them to work: precisely measure load, volume, progression, form… and calibrate your training optimally, based on your unique inner workings.

Who it's for

A solution tailored to every field reality

Individual athlete, coach, club, structure or federation: physiological and metabolic profiling individualises performance analysis from each athlete's own reality, while giving a clear view of groups, teams and their evolution over time.

You are…
Athlete

Understand your physiological and metabolic signature

Every athlete has a unique response to exercise. Their thresholds, their training zones, their energy capacities and their areas for progress cannot be reduced to general averages or to estimates drawn from large volumes of data.

  • Your thresholds, transitions and training zones, individualised — given as power or as pace and speed, as well as heart rate
  • Depending on the profiling option chosen: your VO2max and MAS or MAP, your energy metabolism, your economy (O2 cost) and your gross efficiency (cycling)
  • Your strengths and your current limits, clearly identified
  • A complete view of your training: load (at different levels), volume, fatigue, form…

The goal: train with precise, individualised reference points that are directly usable in the field. You choose the depth of profiling that matches your needs and goals. Far more than simple tracking — a real decision-support toolbox that keeps growing and evolving with science.

Coach

Individualise without losing the collective view

For the coach, the challenge is to understand each athlete precisely, while keeping a clear view of the group. Profiling comes in several options, depending on needs and goals.

  • Calibrate intensities and prescribe sessions optimally, matched to each athlete's unique inner workings
  • Track individual progress on physiological and metabolic indicators specific to each athlete, rather than generic estimates
  • A cross-cutting view of the squad: strengths, weaknesses, similar profiles, differences between athletes and evolution over time
  • Build meaningful working groups from that cross-cutting view — close profiles, shared needs — and programme training group by group, without giving up individualisation

The goal: steer your squad with individual precision — intensities calibrated to each athlete's real inner workings, and an overall view that stays clear. Far more than simple group tracking — a real decision-support tool that keeps growing and evolving with science.

Club · Structure · Federation

Centralise, harmonise and individualise performance

For an organisation, the goal is to move beyond isolated monitoring to a shared tool across all teams, staffs or performance units. Profiling comes in several options, depending on needs and goals.

Unlike approaches based mainly on statistics from large datasets, the starting point is always the athlete's physiological and metabolic signature.

  • Standardise assessment methods and harmonise the indicators tracked
  • Centralise data in a single environment
  • Each athlete keeps an individualised analysis, while the organisation gains a global, comparable and evolving view of performance

The goal: build a shared environment that harmonises methods and centralises data, without ever sacrificing individualisation. Far more than a database — a real performance-steering backbone, flexible: we bring the data from your existing tools into the app as needed, and it keeps evolving with science.
