Design, validation, and testing of an observational tool for technical and tactical analysis in the taekwondo competition at the 2016 Olympic games.

Observational methodology uses validated observational tools to collect information in sports with multiple variables that interact in the sporting context. Given the importance of data quality for observational tools, the purpose of this study was to design, validate, and test the reliability of a mixed observational instrument combining field formats and category systems for analyzing technical and tactical actions in an Olympic taekwondo (TKD) tournament. The instrument collects information of six criteria and 25 categories of the tactical and technical actions, kicking zone, laterality, kicking leg, guard, and score. A total of 2 374 actions were analyzed from 10 bouts involving 12 competitors in the 2016 Rio de Janeiro Olympic Games. The coefficients derived from the generalizability analysis (G coefficients) were used to check the accuracy, validity, and reliability of the tool created, while lag-sequential and polar-coordinate analysis were used to determine technical and tactical patterns of TKD athletes. The results showed optimal G coefficients and provide us with objective, valid, and reliable information on the bout situation analyzed, allowing us to extrapolate the data from our results to the sample population. The lag-sequential and polar-coordinate analyses showed that the competitors scored one point through direct attacks with linear techniques to the chest and performed circular actions with the back leg before and after scoring one point. Three points are scored by indirect attacks and subsequent counterattacks with spinning kicks to the trunk and head (using linear and circular techniques). These results reveal technical and tactical implications derived from the latest modifications of the regulations of this sport, as well as the need to adapt athletes' training for the next Olympic Games.

An update on sparring taekwondo's internal logic / Uma atualização da lógica interna de competição do combate no taekwondo / Una actualización de la lógica interna de la competición del combate en el taekwondo

Abstract: This manuscript addresses the internal logic of sparring taekwondo, regulated by the World Taekwondo Federation, to explain motor actions used in competitions. A narrative review was conducted on Google Scholar, Scopus, Web of Science, Ebsco, PubMed, ProQuest, and Dialnet databases, guided by structural and functional taekwondo parameters with no limits as to year of publication or language used. The authors describe the various elements that make up the sport's internal logic such as regulation, space, time, motor communication, roles and sub-roles in addition to the techniques or execution models that explain their special characteristics. This could assist in further examining the characteristics of that sport, defining combat actions, and contextualizing the real competitive situation by adapting tactical taekwondo sequences. Being aware of this sport's unique characteristics will enable creating the necessary framework to continue research on Olympic-level taekwondo.

Resumo: O objetivo do manuscrito é abordar a lógica interna do taekwondo competição regulamentada pela Federação Mundial do Taekwondo para explicar a ação motora na competição. Uma revisão narrativa foi realizada com base nos parâmetros estruturais e funcionais do taekwondo nos bancos de dados do Google Scholar, Scopus, Web of Science, Ebsco, PubMed, ProQuest e Dialnet, sem limitar o ano de publicação nem o idioma utilizado. Os autores se referem aos diversos elementos que compõem a lógica interna mencionada, como regulação, espaço, tempo, comunicação motora, papéis e subfunções, além dos modelos de técnica ou execução, explicando suas particularidades. Isso poderia nos ajudar a aprofundar as características desse esporte, definir a ação de combate e contextualizar a situação real da competição, adaptando as sequências táticas do taekwondo. O conhecimento das particularidades desse esporte permite criar uma estrutura necessária para continuar o trabalho da pesquisa no taekwondo olímpico .

Resumen: El objetivo de este manuscrito es abordar la lógica interna del taekwondo de competición regulado por la Federación Mundial de Taekwondo para explicar la acción motriz en la competición. Se realizó una revisión narrativa basada en los parámetros estructurales y funcionales del taekwondo en las bases de datos del Google Scholar, Scopus, Web of Science, Ebsco, PubMed, ProQuest y Dialnet sin limitar el año de publicación ni el idioma. Los autores se refieren a los diversos elementos que componen la lógica interna mencionada, como reglamento, espacio, tiempo, comunicación motriz, roles y subfunciones, además de los modelos de técnica o ejecución, explicando sus particularidades. Esto podría ayudarnos a profundizar en las características del taekwondo, a definir la acción de combate y a contextualizar la situación real de la competición, adaptando las secuencias tácticas del taekwondo. El conocimiento de las particularidades de este deporte permite crear un marco necesario para continuar el trabajo de investigación en el taekwondo olímpico.
