Performance Projection

Know the outcome
before you start training.

Deciding what to focus on in training is an informed guess at best. Coaches, scientists, practitioners and athletes may have a good idea what to work on in training: lowering body fat, working on better economy or increasing maximum aerobic capacity – just to name a few. But guessing and knowing for sure is a fundamental difference. Now you can not only know what drives performance, but you can actually quantify performance gains.

Qualitative

“You should lower lactate concentration to improve aerobic fitness and run faster.”

True, and impossible to argue with
No target the athlete can train against
No way to tell whether the plan was worth it

Quantified

“Increasing VO₂max by 5.5%, decreasing energy cost of running by 1 ml/min/kg will lower the carbohydrate combustion rate at marathon pace by 22 g/h and therefore allows to complete the marathon below 3 h.”

A number the training plan can aim at
A goal the athlete can believe and repeat
A retest that either confirms it or does not

Trusted by the best in sport, and far beyond it

From Olympic federations and WorldTour teams to remote coaches, HYROX studios, longevity clinics and human performance labs worldwide.

Start at the end –
Reverse engineering athletic performance

Work backwards from the result your athlete is chasing. Performance Projections enable you to change ANY metric of an athlete: from muscle mass to VO₂max, from economy to glycolytic power, and see the quantitative effect it has on the performance of the athlete. This allows you to not only understand the qualitative effect, but put a precise number on the possible improvement.

No blackbox statistical model – but just clean physiology

There is no statistical guesswork or estimation from specific populations in a performance projection. Instead the projections use the same physiological principles used in the performance test used to capture the metabolic profile of the athlete in the first place. Same physiological principles, same scientifically proven accuracy.

A model, not a forecast

The projection and a real test run through the same metabolic model. If your athlete comes back having actually reached the values you projected, the tested results match the projection. Identical inputs, identical outputs.

Built on this athlete

A projection starts from a real measurement of the athlete in front of you, not a population average and not a regression against somebody else’s data set.

It never pollutes your data

Virtual tests are automatically excluded from the performance development charts. Your athlete’s real progression history stays exactly that.

Orchestrating Performance changes

Physiological Systems are like artists in an orchestra – they interact with each other. And exactly this is reflected in performance projections. You can change several metrics in parallel and see the effect it creates. No extrapolations, no simple linear correlations – just true physiology.

Three aspects of true metabolic modelling

1

The response is individual

How much a change is worth depends on every other parameter the athlete has. Dropping VLamax by 0.07 does not give every athlete 10 percent more FatMax. In some it gives more, in some less. That is exactly why it is calculated per athlete instead of looked up.

2

The response is not linear

Twice the change does not buy twice the result. An athlete who drops VLamax by 0.14 instead of 0.07 does not gain 20 percent FatMax.

3

There is more than one route

The same outcome can usually be reached from several directions. Seeing both routes lets you pick the one this athlete can realistically train in the weeks available, or combine them.

Which metric has to change?
And by how much exactly?

Take the athlete you have already tested, raise VO₂max, drop VLamax or take off fat mass, alone or in combination, and INSCYD returns what each change is worth against the goal you set. This allows you to rank the needed training adaptation and improvements. The result: not only a direction for training but clear, tangible goals on which results and numbers to hit in order to achieve success.

The projection sells the training program.
And the retest sells itself.

At the end of the day, athletes do not test with you because they are curious about any physiological metric you provide. They test because they want to improve and they understand that the first stepping stone is to know what to improve. Showing an athlete precisely not only what to improve but also by how much does two things at once: it triggers the question “how to improve” – which is asking for a training program. And it triggers the question: when to come back to check if I am on track – which is asking for a re-test.

01

Trust, without waiting three seasons

Normally an athlete’s trust in a program is built over years of results. A projection buys a large part of it in one session. The athlete stops being asked to take your word for it and starts seeing which parameter you are training and what it is worth.

02

From hope to a specific number

The athlete moves from “I hope my coach can make me climb faster than last year” to “my coach showed me that five percent more VO₂max and four kilos takes six minutes off my personal best.” One of those is repeatable at a dinner table. It is also far harder to quit on.

03

The retest becomes the athlete’s idea

Once an athlete knows exactly what they are chasing, they want to know whether they got it. In our experience most athletes ask to come back after eight to twelve weeks. The retest stops being something you have to sell and becomes the reward they have been training towards.

Testing labs that had never coached started selling training plans after using performance projections in the post test consultancy sessions, because it triggers the one question every athlete asks next: how do I train for those results?
