Bivariate analysis of taekwondo actions: The effectiveness of techniques and tactics in an Olympic taekwondo championship.
2020
This paper describes the effectiveness of technical-tactical actions performed during a tournament. A total of 14,145 actions of the 2012 London Olympic Games were analysed. Differences emerged in the use of tactics, techniques, zones, legs and guard to score. Regarding tactics, anticipatory counterattacks were the most effective for scoring one and three points. Circular techniques were the most effective for scoring one point, linear to score three points, and spin techniques to score two and four points. Actions to the chest results in a score of one to two points and actions to the head in a score of three to four points. The rear leg was more effective in scoring one, two and four poin…

Fighting and non-fighting time-motion in taekwondo cadet athletes
2016
[Resumen] La relación entre los tiempos de lucha (L) y no lucha (NL) ha sido utilizada para caracterizar las demandas físicas del taekwondo. El objetivo del presente estudio es analizar el tiempo de L y NL en función de la categoría de competición en taekwondistas cadetes (12-14 años). Se analizaron las fases del tiempo de movimiento (L y NL) de 47 combates del primer Campeonato del Mundo Cadete en función de la categoría de competición (minimosca, mosca, gallo, pluma, ligero, superligero, semimedio, medio, semipesado y pesado). Se utilizó el test Kruskal-Wallis seguido de las pruebas por pares de U de Mann Whitney para analizar las diferencias entre grupos (p < 0,05). Se encontraron difere…
Generalizability Theory Applied to Olympic Male Taekwondo Combats
2017
Generalizability theory (GT) postulates that there are infinite sources of error variation in any measurement. Generalizability analysis is used to reduce and control this measurement error. To date, there has been no study employing GT in analysing taekwondo, despite the increase of observational studies in combat sports. Through applying GT to six random combat bouts within the Olympic Games in London 2012, the aims of this study are: (a) to determine whether the bouts selected are representative enough for their behaviour to be generalizable; (b) to determine the intra and interobserver agreement and reliability; and (c) to assess the accuracy of the exhaustive and mutual exclusion of ea…
Comparison of lower limb segments kinematics in taekwondo kick. an approach to the proximal to distal motion
2015
Abstract In taekwondo, there is a lack of consensus about how the kick sequence occurs. The aim of this study was to analyse the peak velocity (resultant and value in each plane) of lower limb segments (thigh, shank and foot), and the time to reach this peak velocity in the kicking lower limb during the execution of the roundhouse kick technique. Ten experienced taekwondo athletes (five males and five females; mean age of 25.3 ±5.1 years; mean experience of 12.9 ±5.3 years) participated voluntarily in this study performing consecutive kicking trials to a target located at their sternum height. Measurements for the kinematic analysis were performed using two 3D force plates and an eight came…
Is It Possible to Predict an Athlete’s Behavior? The Use of Polar Coordinates to Identify Key Patterns in Taekwondo
2019
Elite sport psychologists help athletes develop planned competition strategies from a technical-tactical perspective, through the observation and analysis of previous performances. The aim of this study was to analyze the behavioral patterns used to score points in the 2012 London Olympic Games, by using a mixed observational methodology through a polar coordinate analysis. This analysis is a representation made into four quadrants of the relationships found between focal behavior [i.e., giving score points, (SC)] and conditioned behaviors considered as key factors in taekwondo, occurring before and after the focal behavior (i.e., retrospective/prospective behavior as indicated for each qua…
Continuous play : leisure engagement in competitive fighting games and taekwondo
2023
In order to better understand the development of play and games in modern lives, this article examines two competitive leisure groups: digital fighting game players and traditional taekwondo practitioners. Drawing on qualitative offline/online interviews (n = 56) and close reading of externally documented life narratives (n = 14), we explore how the modes and motives of engagement fluctuate in competitive players over time. The study provides a new developmental approach to continuous competitive play as leisure. Our results show rather than making linear progress from ‘casual’ to ‘serious’ leisure, individuals in both groups perceive their lasting relationships with these activities gradua…
Trunk and lower limb muscle activation in linear, circular and spin back kicks
2015
Background and Study Aim: As any martial art, taekwondo can be classified as a specialty that requires high technical skills, such as a fine motor control both in static and dynamic conditions. Practitioners predominantly use kicks with high amplitude in both combat and technique (poomse) modalities. The aim of this study was the knowledge about trunk and lower limb muscle activation according to the type of kick (circular, linear and spin back kick) in the taekwondo technique modality. Material and Methods: Twelve healthy and elite male taekwondo athletes voluntarily participated in this study. Surface electromyography (EMG) during maximal isometric voluntary contractions (MVC) and executi…
Análise técnico-tático no Taekwondo com coordenadas polares através de software HOISAN
2015
Se lleva a cabo un análisis de coordenadas polares en Taekwondo de las acciones realizadas por los hombres finalistas y semifinalistas en los Juegos Olímpicos de Londres 2012. Para este análisis, se consideraron como categorías focales las acciones relativas a la efectividad de uno, dos y tres puntos, y como categorías condicionadas variables técnico-tácticas para establecer las diferentes relaciones entre las diversas categorías relacionadas con el comportamiento técnico-táctico de los deportistas y la consecución de punto/s. Los resultados mostraron una relación, de excitación en las perspectivas retrospectiva y prospectiva, entre las conductas CAN (Acción de contraataque), CIR (Pierna de…
Effects of a specific training protocol on posturographic parameters of a taekwondo elite athlete and implications on injury prevention: A case study
2018
Introduction: Taekwondo elite athletes should have excellent qualities in several aspects of fitness, as well as peculiar pos- tural characteristics in terms of balance and postural control, to achieve the best possible results during competitions. Moreover, it is known that taekwondo shows high risk of injury. The aim of this case study is to evaluate the effects of a specific training pro- tocol on posturographic parameters of a taekwondo elite athlete in order to prevent the risk of injury. Materials and methods: The specific training protocol provided 2 months of general strength conditioning, which included pre-conditioning in the first 2 weeks, physical training to improve explosive s…
