It is indicated that the parameters of the training modes depend on the intensity and duration of physical activity, its character, and optimization of physiological reactivity of the organism to the load. Maintenance of sensitivity of pulmonary ventilation and oxygen consumption to hypoxic stimulus, as well as preservation and under certain conditions (for example, at a higher pace with a relatively low power component), an increase in the rapid «neural part of the pulmonary ventilation reaction (additional to chemical buffering) the role of respiration to compensate for metabolic acidosis. This factor is important for compensating for fatigue in the process of overcoming the second half of the 2000 m distance in academic rowing. Objective. Theoretically and experimentally, to justify the role of fast kinetics of CRS reactions for increasing the efficiency of functional maintenance of special performance of athletes in rowing academic. Methods and Organization of Research. The research was attended by qualified rowers (n=40). The athletes were ranked in accordance with the level of special working capacity in the test of 2000 m on a special ergometer «Concept II» (, W). In accordance with this, two groups were identified – rowers with a high (group «A») and a lowered (group «B») level of special working capacity. In the experiment, the rowers took part which had ergometric power performance was in the range of 400,0 –435,0 W. The procedure for conducting the studies. A series of experiments was carried out in the natural conditions of the training process during the preparatory period of training. The rapid kinetics and, associated with it, the degree of neurogenic stimulation of the rowers’ energy capabilities is a part of the structure of the functional support of the rowers’ special performance, affects the degree of optimization of the reactive properties of the cardiorespiratory system during the period of steady state and in the process of developing fatigue. Under the condition of fast kinetics, the effect of preserving the values of the reaction of cattle, the efficiency of energy supply of work, and as a consequence of special working capacity under conditions of increasing, as well as in conditions of attaining compensated fatigue, are shown in relation to the conditions of special motor activity of oarsmen.
