Analytical study of some biomechanical variables and their relationship to the strength and accuracy of performance of the front circular kick for Taekwondo players

Abstract

The aim of the search is to: Codification of a skill test according to the electronic drip system for the front circular kick for Taekwondo players, as well as to identify the values of some biomechanical variables for the front circular kick for Taekwondo players and to identify the values of the two variables (strength and accuracy) of the front circular kick for Taekwondo players according to the electronic drip system, in addition to identifying the relationship between the values of Some biomechanical variables and the productive force for the performance of the front circular kick for taekwondo players according to the electronic drip system, as well as revealing the relationship between the values of some biomechanical variables and the accuracy of the front circular kick for taekwondo players according to the electronic drip system. The researchers hypothesized that there is a significant relationship between the values of some biomechanical variables and the producing force of the front circular kick of Taekwondo players according to the electronic drip system, and the existence of a significant relationship between the values of some biomechanical variables and the accuracy of the front circular kick of Taekwondo players according to the electronic drip system. The researchers used the descriptive approach using the two survey methods and the correlational relationships for its relevance and the nature of the study. The research community consisted of taekwondo players, the advanced category, which numbered (75) players representing the players of the teams (Baghdad, Nineveh, and Erbil). The research sample consisted of a sample of the two exploratory experiments, the number of its members (9) players were chosen from the research community, five of them from the Nineveh Governorate team, the tests for the front circular kick were applied, and four from the Erbil Governorate team to apply the biokinematic analysis tests. And the sample of the application of the tests consisting of (50) players representing the teams (Baghdad, Nineveh, and Erbil), and the stability sample consisting of (10) players, in addition to the analysis sample, they are (6) players who were chosen in a deliberate way who represent (3) from the Nineveh Governorate team and (3) From the Erbil governorate team. The researchers used measurement, testing, and technical scientific observation as means of data collection. The scientific observation was carried out using three video cameras at a speed of (100) images/sec. The researchers also used the electronic drip
