Adaptive responses that maintain a high level of functionality current athletes-veterans

Relevance. The article focuses on the adaptive reactions of the main physiological systems responsible for maintaining a high level of functional capabilities in active veteran athletes 37-45 years old, as well as on comparing these reactions with athletes 16-26 years old. The purpose of the study is to determine the adaptive responses that maintain a high level of functionality in active veteran athletes. Research methods. In the compared groups of women, comprehensive studies of adaptive reactions and reserve capabilities of their body were carried out using anthropometric, dynamometric, spirometric, gasometric, immunological, biochemical, hematological, rheographic, ergometric and statistical methods. Results of the study. It is established that a number of functional parameters in active athletes 37-45 years old correspond to the level of 16-26 year old athletes. At the same time, in athletes 37-45years old, there is a tendency to reduce adaptive reserves in comparison with young athletes, and especially with high-intensity modes of muscular work. In turn, maintaining a relatively high level of functional capabilities of athletes 37-45 years old is carried out due to adaptive and compensatory-adaptive reactions, in which hormonal, nervous, hemodynamic and fan adaptation mechanisms are mobilized. It was found that the decrease in aerobic reserves is compensated by an increase in pulmonary ventilation due to an increase in chest mobility. Maintaining the optimal hormonal and vegetative balance occurs with the participation of self-regulation mechanisms aimed at stabilizing the estrogenic background, enhancing parasympathetic nervous influences, mobilizing the circulatory link of the cardiovascular system. Conclusion. The results of the study can be used as a prognosis of the adaptive capabilities of women of involutive-age periods, which maintain a high level of functional state by means of physical training in conditions of regular and prolonged sports.
