PECULIARITIES OF THE INFLUENCE OF WEIGHTLIFTING CLASSES ON THE MANIFESTATION OF PHYSICAL QUALITIES OF SCHOOLCHILDREN OF GRADES 9–11

Abstract

The purpose of this article was to determine the dependence on the specifics of the impact of weightlifting on the manifestation of physical qualities of schoolchildren in grades 9–11. The research was conducted in the Kharkiv Specialized School of I-III degrees No. 162 and the Kharkiv Specialized School of I-III degrees No. 93 of the Kharkiv City Council of the Kharkiv region. To solve the problem, a group of 30 high school students was formed, who systematically practiced in the strength sports section, in particular weightlifting. The age of the subjects was 15–17 years, the experience of continuous training in weightlifting sections was 0.5–1.5 years. Pedagogical testing is presented to determine the level of motor capabilities of schoolchildren of grades 9–11 who were engaged in weightlifting sections. Exercises were identified that are appropriate to use at these stages of training: 30 m run; for 1000 m; shuttle run 4×9 m, s; hanging on bent arms, s; long jump from a standing position, cm; hand dynamometry; bending the body forward from a sitting position. The material presented in this publication shows that the general physical fitness of schoolchildren of grades 9–11, who train in sports sections of secondary schools, corresponds to peers in most indicators, but has more improved indicators. The mentioned facts testify to the slowing down of the processes of deceleration of the physical development of modern children. As a result of testing motor qualities using non-specific exercises, but similar in content to weightlifters, it was found that the indicators improve every year in all exercises (р<0.05 – 0.001). Such a high reliability of the result increase was observed in the period from 9 to 11 grades by 21.1 s (t=4.89; p<0.001) in the 1000 m run and by 0.6 s (t=5.64; p<0.001) in the 30 m run, in the next test the 4 x 9 m shuttle run, the result in two years for schoolchildren of grades 9–11 was 1.0 s (t=7.07; p<0.001), in the weightlifters’ bent-arm hang test Grades 9–11 also saw an increase of 8.8 s (t=4.73 p<0.001), high results in the standing long jump test from grades 9 to 11 improved by 22.2 cm (t=5.82; p <0.001), hand dynamometry for the entire training period was (t=6.50; p<0.001) and in the exercise of bending the body forward from a sitting position for students of grades 9–11, the result was (t=3.98; p<0 ,05), the results that were presented in this paper testify to the high and high-quality training of schoolchildren engaged in weightlifting during grades 9–11.
