Performance diagnostics in NRW, we have been known for this since 2005, initially in Dortmund and since 2012 centrally in Witten in the Ruhr area. Our performance diagnostics is a combination of different procedures and differs from classical procedures such as the (lactate) step test or spiroergometry. The aim of our methods is not so much to calculate but rather to measure as much relevant data as possible. In addition, we endeavour to use a procedure which is valid here on site as well as our customers who live further away, e.g. with a power meter. It goes without saying that the extensive preliminary examinations have to be omitted on your own, but exact performance data have to be recorded and training areas determined in this way.

We also strive to improve our knowledge and improve our training and tests through continuous testing and practical experience of our customers, further education through literature, distance learning or webinars with coaches from the USA.
We are not afraid to change our procedures, we are of the opinion that if you try to achieve the optimum you have to constantly question yourself, and not to be too stubborn to go new ways when you come to the realization that it goes even better.
The results are practical test procedures that have as little influence as possible on the athlete and deliver precise results either in the laboratory or on their own initiative.

Testing Procedures

In our tests we attach importance to testing the performance spectrum of an athlete as comprehensively as possible, therefore the test consists of four or two 8-minute parts (depending on the performance level).
All sections are to be carried out with individually high loads.

During the compilation of the test procedure we have oriented ourselves on the practical tests that leading trainers carry out, e.g. with professional cyclists, combined with our decades of experience that test procedures with rigid specifications often achieved worse results for our customers.

The tests are carried out with certified and calibrated diagnostic instruments, e.g. a fall protection during a treadmill test is a matter of course for us, just imagine you run at full speed and make a mistake! Your safety always comes first.
The test design was chosen by us for extreme accuracy and transferability. So even if the athlete has to do the test himself, we can achieve exact results if it is done exactly, even customers who never make the way to us, we can provide excellent support. Customers from far away in and abroad as far as the USA take advantage of this.

A high-quality electrolyte drink is administered for optimal care during diagnostics.

After the test each athlete receives a regeneration shake to accelerate the muscular regeneration.
It is very important for us to know which test method is the right one and which calculation method keeps the choice out of the discussion. Lactate test, spiroergometry, 3 min, steps, 5 min steps, ramp test, step test - the selection appears almost infinite. We burden you, put simply, so long and hard that we determine the value at stake, namely your individual threshold performance, to a large extent instead of trying to derive and calculate it somehow. This takes longer and is very strenuous, but when you work with the data in practice you will notice that it fits.

In 2014 we predicted the cycling times of our athletes in various Ironman Races to +/- 7 min, and that at a 180km distance, in 2017 it became even more precise, something like this speaks for itself...

In addition, we have already carried out other methods ourselves for years (lactate level tests with 6, later with 12min steps) or tested (spiroergometry, here we could prove a reduction in performance through the mask), at the end we have as in all areas and always thought about whether we do not see potential for improvement and then if necessary also implemented this, we will continue this way so that we will hopefully continue to develop in the coming years.

For customers in ongoing training support, we will even be so individual in 2017 that the tests will look different for every athlete.

Scope Of Services


Already when you come to us for diagnostics we have informed ourselves so far that we can specifically address your situation and know which information we specifically need from you still


Cardiac stress measurement incl. ECG recording, body scan, blood pressure check. Within our framework, we use this data to clarify the basic health of sport and look for potential for optimisation. We are certified Cardiovascular Anti-Stress Center


The best test procedure for you will be selected and applied according to your individual performance level, even beginners will have a load time of just under 40 minutes. During the load a high quality electrolyte drink is served


No later than 7 days after your appointment with us, you will receive an evaluation and presentation of all preliminary examinations, an assessment of your test performance including initial approaches for improvement and, as a first customer, 4 weeks of individual training planning (only for laboratory diagnostics, not for field tests).

Only two prices for maximum transparency 

Make an appointment for a doagnostic in Witten. Don´t worry, we coach worldwide and can guide you through field tests which will allow to setup your training zones even if you are on the other side of the world.
