The Construction of an Athlete's Individual Profile of Speed-Strength Preparedness

摘要

Achieving high results in any sport is impossible without compliance with the proportionality condition in the manifestation of motor abilities. The research problem is to determine the functional dependence of the results in free standing vertical jumps and weighted vertical jumps with different weights. Materials. Data analysis was carried out in 4 groups of subjects representing: powerlifting, kettlebell lifting, basketball, athletics. Were used: scientific literature analysis and summarizing, mathematical modeling; pedagogical testing; methods of mathematical statistics. The height of free standing vertical jumps and weighted vertical jumps with different weights from 11.5 to 110 kg on the shoulders was measured in the subjects. A total of 618 measurements were performed. Checking the adequacy of the equations used to calculate the height of weighted vertical jumps based on the height of free standing vertical jumps taking into account the masses of athletes' bodies and weights showed that it reflects the regularity of the jump height changes depending on the masses of the weights. The equation allows us to calculate individual model values of the jump height as the mass of the weights increases and to assess the proportionality in manifestation level of athlete's speed-strength abilities components. The revealed dynamics of jump height correspondence to the individual normative level allows us to judge insufficiently proportionate use of speed-strength abilities developing means within the framework of the physical training process in various sports, namely, insufficient attention to mainly high-speed and mainly strength components development.
