The athlete’s body-state changes every day. It is related to the training cycle, day of the week, events in private life, etc. These changes are often observed by athletes and coaches when they notice that the exertions or loads easily handled the previous day become heavy the next day. But for all that, such parameters as the pulse rate, blood pressure and others may provide no indications. At the same time, measuring out loads without taking into account the body-state may easily provoke overfatigue and stress. Knowing this, athletes and coaches try to select the load trusting their own feelings and experience. But this approach often fails to bring about the desired outcome.

The ORTO Expert system allows to make an objective assessment of the overall body-state of an athlete and is a useful instrument when selecting a level of exertion. By using the diagnostics of the body-state it is possible to predict the influence of physical loads, to prevent fatigue and stress.

Correct load planning requires dynamic monitoring of the body-state with daily assessment of its changes.

If the body-state is unsatisfactory, the load should be reduced by 30-50%. If the state continues to remain unsatisfactory, the load should be cut by an additional 30-50%. It is not recommended to give up physical exercise altogether.

When the body-state is characterized by the strain of all organism systems, in choosing a load it is necessary to take into account the previous state. If it was unsatisfactory, it is recommended to increase the load by 10-30%. If the state was satisfactory, it is advisable to reduce the load by 10-30%.

If the body-state is steadily satisfactory, it is possible to increase the load by 10-30%. If the state doesn·t deteriorate over time, the load can be further increased.

It may happen that the load increase is constantly causing the deterioration of the state and making it unsatisfactory. This means that the optimal load is reached. In the future, in a few months’ time try to increase the load once again to check how the body got used to the current load.

By using the ORTO Expert system it is possible to choose the load in strict accordance with the capabilities of the body. By changing the load and assessing the changes of the body-state, it is possible to quickly find its optimal volume which would best correspond to the athlete’s system. The combination of the levels of exertion and the body-state can be conveniently shown on one graph.
