CHANGES IN THE FUNCTIONAL STATE OF SKELETAL MUSCLES DURING REPEATED KARATE KICKS

Abstract

Aim. This study aims to determine the quantitative and qualitative characteristics of muscle strength during repeated kicking actions in karate. Materials and methods. Highly qualified karate athletes aged 18–22 years performed repeated kicking techniques. The functional state of the skeletal muscles was assessed using myometry, which recorded oscillation frequency, oscillation decrement, and muscle stiffness. Changes in movement trajectories and angular positions of body segments were also analyzed. Results. The study revealed the nature of skeletal muscle response to specific loading. Temporal parameters of skeletal muscle recovery after intensive specific loading were identified. Changes in the structure of movement technique resulting from skeletal muscle fatigue were also observed. Conclusion. The identified pattern of changes in the functional state of skeletal muscles during specific exercises enables the modeling of training activities in karate.
