The most effective time investment

We live in hurried times. We count every minute. We are looking for the fastest solution. However, there are areas in which it is worth investing. Investing, i.e. making use of the deposit so that we will make a big profit on it..

Time invested in quality diagnostics will save hours of inefficient training and regeneration and days after overloading caused by inappropriate training. On the other hand, you will find out when the training has the highest effect. The use of such a "training window" brings more time savings.


MySASY saves time:

  • provides outputs that were only available from a time-consuming laboratory visit,
  • increasing the training load in the system-identified supercompensation phase demonstrably increases the training effect while maintaining or even reducing the training time,
  • reducing the load in the system-identified phase of reduced regenerative capacity saves time that would be spent on inefficient training,
  • the system identifies the first signs of overloading and thus greatly reduces the likelihood of injuries or other health complications and associated time requirements,
  • measurement with maximum accuracy and report value 1-2 times a week brings more usable outputs to the training process than short-term measurements with only very general outputs.


The results of spectral analysis of heart rate variability (SA HRV) and their use for training management cannot be compared and confused with the indicative "minute fatigue tests", which are provided today by almost every sports watch.


It is true that only scans of at least 300 beats in two basic positions will allow you to evaluate changes in the heart rhythm in all three basic frequency ranges (HF, LF, VLF). The evaluation of the full range of the spectrum is an essential condition for the use of the Spectral Analysis of Heart Rate Variability, providing detailed, unparalleled information to manage training, based on an evaluation of BOTH branches of the autonomic nervous system.

How to monitor SA HRV

Measurement takes place in two positions - standing / lying down. At least 300 beats have to be recorded in each position. Monitoring is preceded by a short lie down providing initial calming. The entire measurement is controlled by the application from your mobile device.


When to monitor SA HRV? To maintain a key opportunity to compare individual measurements, measurements should always be performed in similar standard conditions. Ideally in the morning, after waking up, or before the first daily meal. If it is not possible immediately in the morning, then in another, optimally the same time of day, meeting the following criteria: no significant physical load has occurred on that day; measured at relative psychological rest, in a quiet environment allowing measurements in both required positions; at least 3 hours have elapsed after the last more substantial meal or last coffee.


How often to monitor SA HRVs?

Actual measurements allow you to evaluate the effect of the previous load on the body and then plan or modify the following schedule. Frequency of measurement is not strictly given. It always depends on the goals for which you want to use the diagnostics, the current state of the person being monitored and his/her time options.

General theoretical recommendations


Such an approach will allow you to monitor the body's detailed response to any previous stress and other life events affecting the balance of your ANS. It provides a perfect overview of the body's reactions to each previous stimulus. It allows you to learn how to manage the balance of the organism as best suited to the planned training.

2-4 times a week 

Especially after the days that were meant to change the inner balance in the body. After a significant load, after targeted regeneration, after an event you do not know, what reaction the organism can expect. To get information on whether the training actually caused an expected reaction in the body.

Once a week

This approach will ensure the observation of a general, rather long-term trend. It will help to detect the accumulation of fatigue and / or chronic overloading of the organism in time to prevent overload or overtraining.



In real life, it may be best to alternate and combine the above-mentioned approaches, following the training level, user performance, and current training mode:

A. I'm preparing for my performance limit, I'm preparing for the peak moment of the season, I need to reveal the cause of or overcome the performance problems - I monitor daily


B. Everything in preparation is running as it should, I want to be sure that the training effect does not change negatively - I monitor 2-4 times a week.


C. I am in a training phase that does not burden me significantly or I am unable to influence the following physical load for any reason - I monitor once a week to prevent an unexpected deterioration in the balance / condition of the organism.
