Abstract

Aim: to assess speed-strength motor capacity of flexors and extensors of knee and hip joints, angles of force applications, and muscular performance in weightlifters. Materials and Methods. Polydynamometer produced by Biodex (USA) allows the basic, comparative, and graphic assessment of joint indicators of the upper and lower limbs (flexion-extension) at an angular speed of 150,120,920 deg/s. We examined 6 weightlifters (body weight 63.00±0.98 kg; body length 173.00±1.75 cm) qualified as Candidates for Master of Sport (n=4) and Master of Sport (n=2), aged 18.22±1.74. Results. Integrative assessment of isokinetic testing revealed that desyncrhonization and imbalance of statokinetic stability starts from the muscle system, its angular, temporal, and rotation characteristics, range of movement, dynamical instability of joints, and receptor ratio of groups of muscles participating in motor actions. These integrations are the trigger that leads to disturbances in supporting systems and shifts in indicators as seen from the comparison of involved and uninvolved elements, joint flexion and extension, and deficiency. Conclusion. The used diagnostic equipment allows the determination of muscular imbalance, assessment of structural and physiological capacity, and estimate biomechanical features including differentiation of efforts at various angular accelerations and force application.
