The purpose of the research was to determine the functional state of the cardiopulmonary resection system of male students engaged in the group of sports and pedagogical improvement in boxing, while performing metered physical loads of different orientations. Methods:pulsometry, tonometry, photoplethysmography, spirography, ergometry, methods of mathematical statistics. The results of the conducted research indicate that the volume of work performed directly depends on the weight category. The dynamics of changes in intensity and impact strengths with increasing durability depending on the weight category is different, namely: “light weight” perform a much larger amount of work than “heavy weight”.The biggest differences in the relative strength of a single strike are observed in the left-hand side, which is sufficiently complex for protection and effective for the attack being realized in the melee battle at the most vulnerable place of the enemy-the head. Obviously, this pattern can be determined by the dominant style of duel inherent in “heavy weight”, and/or genetically determined factors, in particular the peculiarities of temperament. This assumption is confirmed by the possibility of heavyweighters to carry out a series of strikes with significant frequency and effort in the shortest possible time, namely: when performing alactatic work, heavy-duty boxers carry a greater number of strokes, indicating a relatively higher ability to generate excitation in the cerebral cortex which is a determinant of temperament, which, in turn, determines the genetic component of readiness for the realization of activity. In boxers of heavy categories, the duel continues at a relatively low pace with a minimum “price” of work; achievement of victory takes place due to a series of bumps in the unprotected areas of the enemy in the alactatious and glycolytic modes of work. For lightweight players, it is inherent in a duel at a fast pace with a correspondingly high “price” of work, exhausting the enemy through the implementation of shock techniques of moderate strength, which ensures the corresponding outcome of the duel. “Heavy weights” take active attacking actions not so often, realizing the potential of stroke with active protective actions. The final effort is carried out with active protection, which causes the victory in the fight.

In modern theory and practice of physical education and sports, sports pedagogy, one of the main areas of training future specialists is to ensure proper management of sports and pedagogical improvement on the basis of objectivization of knowledge about the structure of activity and functional state of the organism. The purpose of the article was to study the functional state of the cardiovascular system of students specializing in biathlon. Methods.Analysis, synthesis, comparison, classification, specification, synthesis of scientific sources on the research problem; study of pedagogical experience, normative legal acts to clarify the essence of the basic concepts of research; pulsometry, tonometry, photoplethysmography, spirography, methods of mathematical statistics. Results. Biathlon students with a relative equilibrium of regulation (eutonium) of cardiovascular activity have a certain tendency to para-, sympathetic dominance, depending on gender. The patterns of the relationship between HRV and pulse wave parameters in women have a lower level of probable significance (p≤0.05), which indicates a relatively lower influence of the para-, sympathetic components of regulation of the tone of peripheral vessels. Conclusion.The revealed patterns indicate the dominance of men in the aerobic component of the functional provision of activities, unlike women, in which this tendency is manifested to a lesser extent, which, in turn, determines the propensity to a greater humoral (ergotropic) and sympathetic regulation of cardiovascular activity. Further research is aimed at determining the functional state of cardioghemodynamics and the autonomic regulation of cardiac rhythm of students specializing in biathlon, depending on the personality’s temporal peculiarities. Taking into account the above-mentioned regularities of functional support of the activity will allow teachers, trainers, and specialists in physical culture to optimize the process of sports and pedagogical training of students in biathlon, depending on gender.

The purpose of the article was to determine the functional state of the cardiorespiratory system and the vegetative regulation of the heart rhythm of male students engaged in the sports-pedagogical perfection groups on boxing when performing the dose-related physical exertion. To implement the goal, the following research methods were used: photoplethysmography, heart rate variability (HRV), cardiointervalography, spirography, tonometry, veloergometry, methods of mathematical statistics. Thus, with comparatively the same relative values of the results of the PWC170 sample, the boxer students of all weight categories, the sympathetic regulation of cardiovascular activity is dominant, which indicates the same tropic support for performing physical exertion. During the restitution period, there is a decrease in the frequency-volume parameters of the respiratory system, to a greater extent, due to the frequency of the respiratory cycles. The centralization index (according to R. M. Baievskyi) remains unrefined in comparison with the results of the sample, while maintaining a tendency to dominate the “heavyweights” of sympathicotonia balance. In this case, the ratio of low-wave to high-wave components of HRV (LF) indicates the dominance of sympathetic regulation of cardiovascular activity of boxer students of all weight categories. It is typical that students-boxers of heavy weight categories have a fairly low overall absolute level of regulatory systems activity, the LF/HF ratio is in the low-wave range, which indicates a low adaptation of the regulation of cardiac activity of boxer heavy students to submaximal load. Since the PWC170 sample is performed mainly in submaximal mode, which is characteristic for lightweight boxers and is non-specific for heavyweights, it is logical that the under-recovery of the trophic (oxygen) function in boxing students in heavy categories is due to the low functionality of the organism to the glycolytic regime of power supply.
