Abstract

The research aims to identify the biomechanical determinants as indicators of skill training by identifying:
- The relationship between biomechanical indicators of (Tkatchev) skill and speed (summary) of body parts during the stages of performance of the skill under study.
- Contribution ratios of biomechanical indicators of skill (Tkatchev) and speed (sum) of body parts to the level of performance of the skill under study
The descriptive approach was used, and the research sample consisted of one player from the national team of women gymnastics (season 2021/2022 AD), who was chosen by the deliberate stratified method, due to her excellence in the performance of the skill (Tkatchev).
The most important results were:
- There are differences in the angular change of the joints of each of the shoulder joints and the joints of the thighs during the performance stages.
-The turning radius, torque of inertia, and angular velocity vary throughout the performance phases.
- Delayed leaving phase and increasing the starting angle.
-Low flight time.
-Increase the height of the center of gravity at the moment of arrest.
- There is a difference between the ratios of the contribution of the biomechanical indicators of the skill (Tkatchev) and the speed (the result) of the center of gravity of the body of the artistic gymnasts.
The researchers recommend paying attention to kinetic analysis as well as anatomical analysis of all gymnastics skills and providing devices and tools for kinetic analysis because of their importance in the process of teaching gymnastics skills.
