Individualities of Cardiorespiratory Responsiveness to Shifts in Respiratory Homeostasis and Physical Exercise in Homogeneous Groups of High Performance Athletes

Abstract

The results indicate distinctive individual peculiarities of CRS response to the shifts of respiratory homeostasis in homogeneous groups of endurance athletes with respect to sensitivity and stability of responses to СО2–Н+. Sensitivity to СО2–Н+ demonstrated a positive correlation with fast kinetics and peak levels in responses to physical loads and anaerobic potential realization. Hyperkinetic and hypokinetic types of an individual physiological responsiveness of CRS to shifts in the respiratory homeostasis and physical exercise in homogeneous groups of high performance athletes were revealed as a premise for athletes’ high specific work capacity.
