Background: The features of functional capacities of elite basketball players related to game functions (players of various lines) have been analyzed on the basis of evaluation of the physiological reactivity characteristics It has been assumed that some specific characteristics are related to efficient competitive activity and are manifestations of endurance: power of cardiorespiratory system (CRS), economy, mobility, stability and ability to realize the potential of the system for specific workload.Material/Methods: Twenty nine elite male basketball players were examined during the competitive period of training. For the analysis of CRS response to physical exercises the complex of the tests for estimating aerobic capacity and anaerobic possibilities of athletes were used.Results: The results showed that basketball players of various game functions have different levels of functional fitness and components of aerobic capacitiesConclusion: A possibility to efficiently control the preparation of athletes and determine the most optimal character of their competitive activity has been considered on the basis of an account of functional capacities level and differences in its levels in athletes of different game functions.

Background: The aim was to study changes in the sensitivity of CRS responses of skilled athletes caused by fatigue during a strenuous physical load.Material/Methods: Response sensitivity to hypoxic and hypercapnic stimuli was analyzed in a group of high performance rowers (n=12) aged 18-22 years during exercising on "Concept-II" rowing ergometer. Two types of loads were used: sustained intensive load at high oxygen consumption (78-83% of VO2max) and relatively easier load (49-62% of VO2max) performed within 5 minutes. The method of rebreathing was used to determine responses sensitivity to CO2.Results: The results showed an increase in respiratory response sensitivity to hypoxia and a decrease in sensitivity to acidosis stimulus of respiration (CO2-H+) at the end of a strenuous load in presence of fatigue. Ventilatory response to hypoxic stimulus increased reliably before the end of work. At high intensity of loads during increment hypercapnia even in highly trained athletes the inhibition of ventilatory response has been notedConclusions: The data provide additional grounds for correction of fatigue by means of regulating the character and the intensity of physical loads in the process of endurance training. It has been shown that changes in sensitivity of CRS responses and other aspects of reactive features are of importance for special work capacity manifestations.

Background: It is known that high sports performances are based upon optimization of adaptation process. In order to achieve the above, one should provide a maximal account of individual vivid features of athlete's abilities, peculiarities of his/her physiological reactivity. The aim was to study individualities of sensitivity to shifts in respiratory homeostasis and responsiveness to high intensity physical exercises in homogeneous groups of high performance endurance athletes.Material/Methods: Individual peculiarities of the cardiorespiratory system (CRS) physiological reactivity were evaluated in 118 high performance endurance athletes (cyclists, runners and rowers) aged 20-27 years (competing regularly in sports for 6.8 ± 1.1 years). The sensitivity of response to CO2-H+ (rebreathing), fast kinetics and the peak response of CRS to various physical loads were measured. The level of VO2max and accumulated oxygen deficit were determined as well.Results: 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 CO2-H+. Sensitivity to CO2-H+ demonstrated a positive correlation with fast kinetics and peak levels in responses to physical loads and anaerobic potential realization.Conclusions: 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.
