Evaluation of functional state and physical preparedness of athletes on indicators of the heart rate variability
The author considersa variety of methods for assessing functional status and physical fitness of athletes (physiological, biochemical, method of testing in the laboratory). It is shown that for the control of the functional state of the athletes it is advisable to use the method of analysis of heart rate variability as the most informative, accessible and objective. It is established that the increase of physical performance and efficiency of competitive activities of athletes playing sports are associated with increased regulation of independent contour, increasing the total capacity of the spectrum, a moderate activation of the sympathetic division of the ANS during active orthostatic test. The lack of growth performance and reducing the impact of competitive activity paired with a decrease in activity of the sympathetic division of the ANS during the functional tests, with a reduction in the power of all spectral components at rest.
