Combined metabolic, movement and force-plate assessment
Aerobic physiology, blood lactate, movement strategy and force production, measured in a single session and interpreted against one another in one report.
Four assessments in one session, recorded under the same conditions on the same day. Open any of them for what it covers and what it changes.
How we measure it
Indirect calorimetry at complete rest, measured first — while you are still rested and fasted, before anything else in the appointment can affect it.
How we measure it
A structured assessment of how you organise your body under load. What positions and shapes you can access, where relative motion is available or restricted, and how pressure is managed across a range of tasks.
How we measure it
Hawkin Dynamics force-plate protocols, run while you are still fresh. Records braking and propulsion, impulse, time to take-off, velocity, power and each limb’s contribution.
How we measure it
Breath-by-breath analysis of oxygen and carbon dioxide across a progressive protocol, with fingertip lactate sampled at the end of every stage. Run last, because it is the only part that takes you to maximal effort.
How we measure it
A separate appointment of 45–60 minutes at a steady intensity relevant to your event, with fluid balance measured across it and a regional patch for sodium where available.
How we measure it
Drawn from reading the data sets against each other rather than in isolation.
Why it matters
Disagreement between areas is usually where the clearest opportunity sits, which is what the report leads with.
How we measure it
Selected from the full data set against the demands of your sport.
Why it matters
Lets later testing be targeted rather than repeated wholesale, so a reassessment measures change rather than describing your physiology again.
How we measure it
An integrated summary, then the metabolic, movement and force sections in full, with interpretation of what each measure is useful for.
Why it matters
Closes with priorities, KPIs and a recommended interval before retesting. It describes your current profile and sets priorities; it does not diagnose injury or guarantee that injury will be avoided.

Everything we measure, in an order chosen so each part is recorded under the conditions that make it meaningful — written up as one interpretation rather than six reports.
Measured with
About three hours in one appointment. The sequence is deliberate: the metabolic work comes before the force protocols so that fatigue does not distort either.
Choosing
60–90 minutes · Aerobic physiology and blood lactate. Pacing, thresholds and training intensity.
~60 minutes · Movement strategy alone. How you organise load and what shapes your restrictions.
~60 minutes · Force production alone. How force is produced and distributed.
~3 hours · All four areas in one session, interpreted against one another in a single report.
If your question is entirely about pacing and training intensity, the Endurance Performance Profile answers it at £300. Choose the complete profile when you want the relationships between the areas, not simply more measurements. The sweat and hydration work runs as a separate appointment, because a representative sweat rate needs 45 to 60 minutes at a steady intensity.
This assessment is not suitable for everyone, and we would rather say so before you book than afterwards. If a single assessment answers your question, book that instead.
Because you want the areas read against each other. If your question is entirely about pacing and training intensity, the Endurance Performance Profile at £300 answers it and costs less. Complete Athlete Profiling suits athletes whose question spans more than one area — where a movement or force finding might explain something the physiology alone does not.
Bought separately the same assessments come to £1,035 — £200 for metabolic testing, £100 for the blood lactate addition, £135 for resting metabolic rate, £300 for movement strategy, £150 for force and power, £150 for sweat and hydration. So there is a £140 difference. But the report is written across all of them rather than as six separate documents, and that interpretation is the substance of what you are buying.
No. It suits athletes with a specific performance question and the intention to act on the answer over a training block. If you are not currently training to a structure, or want a single measurement, a shorter assessment is the more sensible choice.
No. It is a performance assessment, not a clinical examination. It does not diagnose injury, and it does not guarantee that injury will be prevented. Findings describe how you currently produce and organise movement and force. If something in the assessment warrants clinical attention, we will say so and recommend you see an appropriate professional.
Not by itself. Differences between limbs are common and frequently reflect the way an athlete organises a task, their sport, or their training history. What matters is whether a difference is consistent across protocols, whether it aligns with the movement findings, and whether it changes over time. It is interpreted in context rather than treated as a defect.
Approximately three hours for the main appointment, plus a separate session for the sweat and hydration work. The order within the main appointment is deliberate: resting metabolic rate first while you are rested and fasted, then movement strategy before meaningful fatigue develops, then the force plates while you are still fresh, and the metabolic and lactate protocol last because it is the only part that takes you to maximal effort. The sweat assessment needs 45 to 60 minutes at a steady intensity, which cannot be produced by a protocol that keeps increasing — so it gets its own appointment rather than being squeezed onto the end of one.
Fast for at least four hours, because resting metabolic rate is measured before the exercise protocol begins. Avoid intense training for 48 hours beforehand where possible and certainly the day before, arrive well hydrated, and wear the kit and footwear you train in — bring shorts for the movement assessment and cycling shoes if you are testing on the bike. Preparation matters more here because arriving fatigued affects all four areas rather than one. Allow the full three hours; the review at the end is where most of the value is delivered.
Typically after a full training block, at 12 to 16 weeks or longer. Because this establishes a broad baseline, many athletes retest a single area sooner and return to the full profile annually or before a significant training phase.
