Compensatory-adaptive mechanism of cardiorespiratory system in athletes’ fatigue state

At the present level of sports development, the search for opportunities to improve the performance and endurance of athletes is one of the most important terms for achieving high sports results. Performing physical activity at the limit level makes increased demands on the activity of the body, requires more significant adaptive changes in the functioning of all organs and systems, but it allows to raise the overall level of efficiency. Factors that determine the effectiveness of combinations of training loads are the volume of loads, their direction and sequence of execution. Consideration of these factors should be reflected in the organization of the training process. The combination of training loads aimed at the education of general, special and strength endurance should be most often used in the general preparatory stage of the preparatory period, and the combination of loads aimed at the education of special, speed and strength endurance - in the special preparatory stage of the preparatory period and in the competitive period. Planning the volume and intensity of the training load and its implementation should correspond to the functional capabilities of the athlete’s body. To prevent the probability of any deviation from normal functioning of energy sustaining systems of the body, one needs a speedy and effective recovery of these systems. Only in this case the training process can proceed quite systematically, and the results of the trainee will become more stable at all stages of the competition period. All this makes it relevant to study the processes of rational interaction of cardiorespiratory and motor systems of the body during training and competition. This knowledge allows with a sufficient degree of accuracy to determine the development of the performance of athletes, optimize the training process, improve its quality and efficiency, maintain a high level of performance for a long time.
