BIOMECHANICAL CONTROL OF TECHNIQUE EXECUTION IN COMPETITIVE POWERLIFTING EXERCISES

The purpose of the work carried out was to introduce into the training process of powerlifter athletes a system of biomechanical control of the technique of performing competitive exercises. To achieve the purpose of the study, a system for monitoring © Беляев А. Г., 2024 kinematic indicators of the technique of performing competitive exercises in the training process and within the framework of competitive activities was formed, which was tested with the help of a formative pedagogical experiment that lasted from January 10, 2023 to December 25, 2023. The obtained results were processed using mathematical statistics methods. According to the results of the experiment, we obtained an average increase in the amount of triathlon in the competitive season of 21,9 %, but at the same time only three monitored indicators changed statistically significantly — a decrease in the active phase time in the bench press, an increase in the average speed of the projectile in deadlift and a decrease in deadlift time. It is also worth noting a significant decrease in the number of anomalies in the bench press and deadlift and a decrease in the deflection of the projectile along the vertical axis in squats with a barbell.
