RETRACTED ARTICLE: Improving the physical qualities of professional boxers by considering their personality traits

The study analyzes the development and improvement of physical qualities in modern sports and examines the optimal parameters in general and individual training of boxers. The paper describes a pedagogical experiment to explore the effectiveness of the author’s methodology for the development and improvement of physical qualities considering boxers’ personality traits. The experiment involved 30 boxers from the national team of the Republic of Kazakhstan, which is among the strongest teams in the world (15 people in the experimental and 15 people in the control group). The experimental group demonstrated a statistically significant improvement in 7 out of 9 dimensions: pull-up on the bar (t = 2.927; P ≤ 0.01), bench press from the chest (t = 2.253; P ≤ 0. 05), weight push from the chest in front (t = 3.467; P ≤ 0.01), 100 m run (t = 3.100; P ≤ 0.01), jump from a place (t = 2.444; P ≤ 0.05), 1st 400 m run (t = 2.654; P ≤ 0.01) and 2nd 400 m run (t = 2.354; P ≤ 0.05). The experimental group significantly surpassed its background results and the control group’s results in seven indicators of physical fitness out of nine. This fact suggests that the author’s experimental technique effectively improves the physical qualities of highly skilled boxers. A two-way analysis of variance showed higher efficiency of improving physical qualities when using the author’s methodology and the absence of differences between different weight categories. The study can be of practical use for sports coaches and psychologists who want to improve the physical qualities of athletes, following the methodology proposed by the author. In addition, the materials of this work can be useful in studying the management of performance and creating a favorable psychological climate for improving physical qualities of boxers, considering the characteristics of an athlete’s personality.
