Polyfunctional express-evaluation criteria of the sportsman organism state

Abstract

After examining 1930 male athletes, which included three consecutive two-minute measurements using the SACR, followed by an analysis of individual components of the spectral power of the heart rate variability (HRV), variability of systolic blood pressure (SBPV) and diastolic blood pressure variability (DBPV), and spontaneous respiration (SR)and controlled respiration (CR) together with designed centennial tables, the ranges of which differ significantly, the spectrum of normative values of heart rate variability indicators, systolic and diastolic blood pressure, breathing at random and controlled respiration were determined. While conducting tests on CR compared with SR, it is found out that CR6 significantly increases the LF component and reduces the HF component, and CR15 slightly affects the LF component and significantly increases the HF component of the spectral respiration power. It is also noted that CR6 and CR15 activate various regulatory links of system hemodynamics: at CR6: an increase in the LF component of respiration regulation is transferred to the LF component of regulation of HR, SBP and DBP, while the decrease of the HF components of respiratory regulation does not significantly affect -components of HR, SBP and DBP; at CR15: as light increase in the LF components of respiration regulation practically does not affect the LF components of regulation of SBP and DBP and reduces the LF component of regulation of HR, and asignificant increase in the HF components of respiration regulation is transferred to the HF components of regulation of SBP and DBP and practically does not affect on the HF component of the HRV. Thus, the data obtained during testing can be used for the comprehensive evaluation of reactivity and depressor changes in the activity of the sympathetic and parasympathetic ANS units in the regulation of the cardiopulmonary system, which are used to diagnose the functional readiness of an organism in conditions of training and competition processes.
