THE STRUCTURAL LINGUISTIC APPROACH TO CARDIAC RHYTHM CLASSIFICATION FOR ATHLETES DURING THE INITIAL ADAPTATION STAGE TO ALTITUDE CONDITIONS

Abstract

We have implemented the structural and linguistic approach to study the cardiac rhythm variability of athletes competing in speed-power disciplines. The athletes were subjected to altitude-induced hypoxia. We have derived the formula that describes the adaptation reactions and the key characteristics of the cardiac rhythm spectrum, such as frequency and amplitudes of main spectral maxima.
