Detection of the technical and tactical motion of the scorable movements in taekwondo.

The objective of the study is to discover and analyze the patterns of the technical and tactical moves that score in combat in taekwondo. We analyzed 209 moves that could be scored (male category, <68 kg, international scene) employing different complementary analytical techniques: analyzing traditional statistics, detection of T-Patterns, consecutive delays and polar coordinates. The existing studies in taekwondo only use technical analysis. The complimentary relationship of technical analysis is a rare experience due to the strength that it entails, with just as much human resources as material resources. This situational analysis provides the technical and tactical aspects of the scorable actions in taekwondo, discovering which standard drivers permit a competitor to score. In the actions targeted towards the face, it is more common to score as a fault, doing the opposite of the actions towards the breastplate. The techniques that are used the most to score are bandal chagui, miro chagui and dolio chagui. Among the technical and tactical moves that score, we highlight the direct attack moves (a kick to the breastplate with the back leg extended bandal chagui), in counterattack and for technical correction. We suggest reinforcing these actions in the trainings.

Technical analysis in Tsuri-goshi through three complementary observational analysis.

The aim of this article is to identify the factors involved in learning judo based on an observational study of technical errors and their relationships. The analysis was carried out using a combination of a self-generated observational instrument (OI-JUDO-TG) and a recording instrument (developed with the Lince software) using a sample of 78 novice students. In addition, descriptive statistics and sequential analysis with polar coordinates and T-Patterns were obtained using the Hoisan and Theme software program. The implementation of the various analytical methods optimizes the knowledge of performance and the concretion of feedback, like the process of communication between the teacher and the student, that which will activate new neuronal connections in learning. The results confirmed that the most frequent chain of errors during the performance of the technique were as follows: (1) the lack of an initial imbalance, the incorrect placement of the feet, the head and (2) the head after the tsukuri of the technique, as well as the absence of load of the body during this phase and the lack of balance of the performer when finishing the projection. At the initiation of judo, analytical methods are not applied, but the personal experience or the immediate feedback from the teacher is applied. It proposes a new analytical method to learn the technical errors and the different ways to implement their correction. Through the observational analysis generated, intense relationships between the detected errors have been demonstrated, determining the presence of the ones that causes the occurrence of the others.
