Dynamic correspondence of barbell squat training to competitive exercise in powerlifting

Aim. The paper aims to identify the correspondence of barbell squat training to the competitive exercise in powerlifting with respect to the dynamic characteristics of movements and to reveal their hierarchical dependencies. Materials and methods. The following methods were used for the purpose of the study: theoretical analysis, data generalization, accelerometry, mathematical statistics. The study took place at V.S. Sokolov Children's and Youth Sports School (Cheboksary) in December 2019. The study involved 7 athletes (1st sports rank to the master of sport). 9 variations of training and competitive exercises were subjected to metrological assessment; 84 measurements were performed in total. Results. The following levels of correspondence were identified: maximal (slow squat and quick rising; squat heel together, socks apart; bench squat), high (chain squat; barbell front squat; wide stance barbell front squat), medium (stop squat; slow squat and slow rising). Conclusion. The comparative analysis made it possible to identify exercises with different levels of correspondence to the competitive ones and, thus, to identidy their hierarchy. This will provide a more consistent approach to the choice of exercises for skilled powerlifters.
