БИОМЕХАНИЧЕСКОЕ ТЕСТИРОВАНИЕ МЫШЕЧНОЙ РЕГУЛЯЦИИ НА BIODEX SYSTEM 4PRO ЮНОШЕЙ-ТЯЖЕЛОАТЛЕТОВ ВЫСОКОЙ СПОРТИВНОЙ КВАЛИФИКАЦИИ СРЕДНИХ ВЕСОВЫХ КАТЕГОРИЙ

Aim. The aim of this article is to estimate strength capacities of weightlifters’ limbs to improve movement technique, statokinetic stability, energy production, muscle recruitment, viscoelastic properties, muscle relaxation and contraction. Materials and methods. We examined 10 male weightlifters aged 16–18, having qualification of the Candidate for the Master of Sports (n = 8) and Master of Sports (n = 2). Their body length varied from 173 to 176 cm. To assess joint isokinetic movement, we used Biodex System 4Pro multi-joint complex (Biodex Medical System, Jnc, USA). Results. We revealed numerous biomechanical parameters and their correlations with balance and disbalance, which reflect the integrative activity of the statokinetic stability system in weightlifters. It should be noted that correlation analysis, in comparison with the analysis of absolute values changings, reflects more objectively statokinetic stability in weightlifters. Conclusion. The results obtained allow us to describe biomechanical properties of joint flexion and extension (knee, shoulder, pelvis joint).
