The benefits of mySASY

vital information about your training after just a few measurements
  • Your training typology

    Are you a Talent or a Threat? The mySASY profile will show you how the body resists central fatigue and responds to stress. How fast or slow it can regenerate. You can easily see where you have the potential to improve. Within the mySASY profil we tell you if you are Talent, Threat, Holder or Classic. We also monitor your long-term ability to resist central fatigue and to adapt to training load.

  • How to design your training

    mySASY monitors your autonomic nervous system through heart rate variability and brings you the most accurate information about the condition of your organism. Simply said, based on that information you will be able to efficiently adjust your training plan. Thanks to measurements you will find the right moment when to train harder and when it is better to concentrate on recovery.
    More Information
  • Help you prevent injuries

    Using the monitoring of the recovery process in the body and of the current state of the organism, we give you the information whether you are ready for your next training. This way, we help you eliminate the risk of overtraining and injury.

Modul myTraining

The Modul is an integral part of all mySASY programs. Thanks to our own algorithmic interconnection of training data with mySASY measurements you will have key information for training management after the first 10 measured and recorded activities.


Optimal workload

What is the optimal workload for the next training unit? We will calculate it for you and you will be able to adjust the intensity with a slider, determining the duration of the training.

Results vs Potential

Your real long term training potential compared to the effect of the current training regime.

Compensation levels
go hard or go rest?
The compensation level helps you plan the appropriate regime for your following training load. The value is based on a comprehensive comparison of your current measurement with the results of previous measurements, with the so-called individual spectral profile.
Functional age
organism's real age
Proper training will help you to rejuvenate. We'll show you how to do this and how to document it. Thanks to the functional age you can see your condition at first glance. After proper training, you get a little older. After that, proper regeneration will cause the desired rejuvenation.
Modul myTraining
evaluation of the real training effect
This module allows you to upload your training data and link it to the measurement results of mySASY (your body's condition). You can enter training data manually using subjectively perceived load and time (RPE parameter), using TSS units (Training Peaks system), or use the automatic connection to the Strava application (Relative Effort parameter).
New ~4 minute measurement
Thanks to advanced artificial intelligence and state-of-the-art mathematical calculations from Gauss Algorithmic we were able to shorten the time of standard mySASY measurement from 15 minutes to approximately 3-5 minutes.
Unlimited mySASY profiles
The mySASY profile will show you how the body resists central fatigue and responds to stress. How fast or slow it can regenerate. Within the mySASY profil we tell you if you are Talent, Threat, Holder or Classic. We also monitor your long-term ability to resist central fatigue and to adapt to training load.

Functionality verified in a scientific study

The main basis was data from hundreds of thousands of measurements and an AI model that would perform an analytical calculation. A single professional analyst would have to work for 3 years without interruption to get to the same result. At Gauss Algorithmic, they tested various approaches, including recurrent neural networks, and finally chose the Gradient Boosting Decision Tree (GBRT)
