Effectiveness of Computerized Biomechanical Assessment of Throwing Technique in Qualified Wrestlers

Abstract

Presents the results of an experimental study on the effectiveness of computer biomechanical analysis in improving the technical training of qualified wrestlers. The aim of the study was to determine the effect of an integrated biomechanical throw-assessment system on athletes' competitive performance. Thirty-two wrestlers (Masters of Sport and Candidates for Master of Sport) participated in the pedagogical experiment and were divided into a control group (n=16) and an experimental group (n=16). The experiment lasted six months. The control group trained according to the standard programme, while the experimental group additionally used a hardware-software complex for three-dimensional biomechanical motion analysis based on inertial sensors and computer video modelling. Kinematic and dynamic parameters of the key throw elements were recorded: joint angular velocities, trajectory of the overall centre of mass, and the temporal force-transfer profile. As a result of the experimental methodology, athletes in the experimental group showed a significant improvement in biomechanical movement coordination (p<0.05); the effectiveness of technical actions in competitions increased: the throw execution rate rose from 38.4% to 56.7%, and the judges' technical score from 6.1 to 7.8 points. It was established that systematic feedback through computer biomechanical data forms a more stable motor stereotype and accelerates the correction of technical errors. The data obtained confirm the feasibility of introducing computer biomechanical technologies into the training system for qualified wrestlers.
