Structure of physical fitness of young athletes 14-15 years old who specialize in wrestling sambo.

Abstract

It is revealed that during the active biological and mental development of the athlete, which coincides with the previous and speci alized stages of basic training, significant changes occur in the body, and increased training and competitive loads can negatively affect the student's state of health. This fact is typical not only for wrestlers, but also for representatives of other sports; In the scientific and methodological literature on sports wrestling there are practical recommendations that allow to plan physical activities of different orientation only for athletes of higher qualification using a complex approach. However, the developed system of training actions is acceptable at the stages of higher achievement and is not effective during the period of active physical and mental development of a young athlete, ie at the stages of basic training. The introduction of the factor analysis method in the process of interpreting the experimental data obtained allowed us to determine that the structure of the aforementioned training of young athletes consists of five orthogonal factors, the contribution of which is equal to 85.5%. The weight of the general factor is estimated at 19.8%, and its content is formed by the index of long jump and maximum dynamometry. The contribution of the next factor is slightly smaller - 19.6%, and the highest coefficient in this case is the results of pulling and running for 30 m. The third most significant factor is indicated by the weight of 17.4%, and the greatest influence on its formation is indicated by the number of trunk lifts per 1 min and the amount of the tapping test. The contribution of the fourth factor is estimated at 16.7%, with the greatest weight in it having the results of running at 3000 m and the average value of the tapping test. The final factor is indicated by a significant weight factor of the running indicator "4 x 9 m", and its contribution to the total variance of the sample is estimated at 12,%.
