The effect of physical fitness on the morpho-functional state and the energy costs of skilled archers

Abstract

The prospects of directions of improvement of technical preparedness of athletes in archeryare studied. The content of scientific and methodological studies allowed to form perspective directions in improving the technical preparedness when reaching the necessary level of special physical preparedness. The purpose of the study is to study thedependence of energy expenditure indices on the physical performance of athletes of bowstring arrows. The following methods were used for the study: theoretical analysis and generalization of the data of scientific and methodical literature, medical and biological (hygienic analysis of the data menu of the daily food rations), sociological methods (questionnaires), the method of mathematical statistics (checklists in the program Microsoft Excel). Results of work and key conclusions. Athletes during training or competition standing in a shotgun and aiming at the target perform a complex coordination work that requires appropriate energy costs and endurance of the muscular system.The average energy expenditure for 14 days of motor activity is 2,554 kcal, with the officially adopted norm for boys and girls 2 times higher, which gave us the opportunity to develop the recommended values for this age and actually in archery. The main factor in the correct functioning of the athlete's body during the training and competition periods is the process of restoring morpho-functional systems and the performance of athletes, which occurs due to energy value.Conclusions Taking into account the features of the shooting, it can be argued that the technique in this type of sport is aimed at achieving a certain structure and content of movements that provide maximum accuracy for the highest sporting result. It is important to provide stable criteria and information about the structure of the organism, the functional capabilities of the organism, morpho-functional models of the organism.
