ABSTRACT
On the basis researches of character responses of respiratory system (RS) on hypercapnic and physical load at 54 skilled athletes (the runners on 100, 800 and 5000 m) are analyzed of the features in physiological reactivity of system on shifts respiratory homeostasis, reflecting a various orientation of long-term adaptation (sports of the training). The interrelation of sensitivity and stability of responses to hypercapnic (CO2-H+), and also limits and kinetic characteristics of responses RS of physical loads with manifestation of work capacity and mobilization features aerobic and anaerobic processes of during physical loads energy-supply was demonstrated. By means of tacsonomic analyses are allocated types of individual responses of organism of the skilled athletes on the basis of character RS responses to hypercapnic shifts in respiratory homeostasis. They in a high degree have been caused by sports specialization of athletes.
