Abstract

Introduction. Studying the level of functional state, as well as the formation and expansion of the reserve functions of the body of young athletes is one of the important and urgent problems of training the sports reserve. The study shows the impact of the author's physical training program on the dynamics of indicators of the functional state of young nordic-combinators. Purpose. To determine the influence of the physical training program taking into account the criteria of physical fitness on the level of functional condition of young nordic-combinators. Methods. Theoretical analysis and generalization of scientific literature, express diagnosis of the functional state and reserve capabilities of the body D&K Test, determination of the level of urea in biological fluids, determination of the level of lactic acid, determination of the level of catecholamines, methods of mathematical statistics. Results. In total, 20 young nordic-combinators aged 12–14 took part in the study. The athletes of the experimental group trained according to the author's program «Improving the structure and content of physical training of biathletes at the stage of preliminary basic training». According to the results of the study, during the first stage of the experiment, the athletes of the control and experimental groups experienced positive changes in all the studied indicators of the functional state. The use of the author's program led to significant (Р<0,05). positive changes in the level of adrenaline excretion of the athletes of the experimental group in response to a standardized bicycle ergometric load, the difference was 30.6%. Athletes of the control group had statistically significant positive changes in adrenaline excretion rates by 14,3%. Originality. For the first time, the influence of the author's program on physical training, taking into account the criteria of physical fitness, on the level of functional condition of young nordic-combinators at the stage of preliminary basic training has been determined. Conclusions. The results of pedagogical experiment indicate that the use of program structure and content of physical training improvement of nordic combined skiers on the stage of preliminary basic training taking into account the criteria of physical preparedness and the importance of functional status indices, has caused the improvement of indices of athletes’ physical qualities and components of training. It has also contributed to certain growth of both general and special physical preparedness without increase of training loads.
