Analysis of technical errors during the execution of the classical jerk by young weightlifters at the stage of preliminary basic training

Abstract

The purpose of the article was to study the analysis of technical errors during the performance of the classical jerk by young weightlifters at the stage of preliminary basic training. The study was conducted at the Kalnyshevsky State Secondary School No. 2 in the city of Romny and the Poltava State Secondary School No. 2.42 athletes of the pre-basic training stage aged 12-13 years in the category up to 45 kilograms participated in it. For the distribution of athletes into groups and, in turn, to identify the high average and low level of physical and technical preparation, we conducted control and transfer standards. Thus, in the course of our research, it was found that athletes with a low level of physical fitness should focus their attention on the technical component and work in the range of 60-70% from 5 to 7 repetitions per approach. The quality of execution of the elements of the classical jerk technique among young weightlifters aged 12-13 years of different groups according to the level of physical fitness was revealed. The highest quality indicators were obtained in group 1 (high level) of physical qualities in "athlete's interaction with the barbell" (5.1±0.52 points), "pre-acceleration" (5.1±0.45 points), "depreciation phase" (4.2±0.29 points), "final acceleration" (5.3±0.31 points), unsupported squat (7.0±0.32 points), supported squat (6.8±0.52 points ), fixation in a squat (6.7±0.45 points), standing up and fixation (6.3±0.29 points), which in most indicators is reliably better than in groups 2 (average level of physical qualities) and 3 (low level of physical qualities). Such a small percentage, and the corresponding high number of repetitions during the training process, will be able to eliminate many technical errors and shortcomings. Athletes with a low level of physical training, in turn, should pay great attention to exercises for the development of general and special physical training, improve strength indicators in auxiliary exercises, which, in combination with technique, will certainly improve their overall results.
