          Abstract

          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 golpeo dirigida hacia el oponente) e IZQ (Golpeo realizado con la pierna izquierda) con respecto a la conducta focal EF1, mientras que las conductas GIR (Acción realizada con un giro previo) y ABI (la pierna delantera de ambos oponentes es diferente) lo están con la EF2; sugiriéndose así el entrenamiento de las citadas acciones con vistas a la consecución de dicha puntuación. Este estudio ha permitido comparar las relaciones que se establecen en la utilización de estrategias de interacción en el deporte de taekwondo. El análisis se ha realizado utilizando el software de observación HOISAN que ha permitido solventar las dificultades planteadas anteriormente en la realización y uso de esta técnica.

          Com o objetivo de compreender as ações realizadas no Taekwondo analisaram-se as ações dos atletas masculinos finalistas e semifinalistas nos Jogos Olímpicos de Londres 2012, com recurso à análise de coordenadas polares. Para esta análise, consideraram-se como categorías focais as ações relativas à obtenção de um, dois e três pontos, e como categorías condicionadas as variáveis técnico-táticas, de modo a estabelecer as diferentes relações entre as diversas categorías relacionadas com o comportamento técnico-tático dos desportistas e o alcançar de ponto(s). Os resultados mostraram uma relação excitatória nas perspetivas retrospetiva e prospetiva, entre as condutas CAN (Ação de contra-ataque), CIR (pontapé circular) e IZQ (pontapé realizado com a perna esquerda) no que respeita à conduta focal EF1, enquanto que as condutas GIR (Ação realizada com uma rotação prévia) e ABI (a perna adiantada dos dois adversarios é diferente) mostraram a mesma relação excitatória no que respeita à conduta EF2; sugere-se assim o treino das citadas ações com vista à obtenção da pontuação mencionada. Este estudo permitiu comparar as relações que se estabelecem na utilização de estratégias de interação no Taekwondo. A análise realizou-se com recurso ao software de observação HOISAN que permitiu superar as dificuldades colocadas anteriormente na realização e uso desta técnica.

          The aim of the current research was to provide a novel perspective on the understanding of the actions performed in Taekwondo, to do this, the actions performed by the men finalists and semifinalists in the Olympic Games in London 2012 were analyzed. Based on a taxonomic and methodologically validated system, analysis of polar coordinates was performed using the genuine analytical technique. This technique allows us to know the relationship between the focal category and various conditional categories, in addition to build different behavioral maps. To perform the mentioned analysis, were chosen as focal categories those actions relating to the effectiveness of one, two and three points while as conditional categories were chosen technical and tactical variables. This innovative technique of analysis was implemented by using the observation software HOISAN. The software allows to remove the difficulties previously raised when using this technique.

            Taekwondo: Physiological responses and match analysis.

            The aim of the present study was to determine the time structure and physiological responses during Songahm Taekwondo (TKD) competition and to compare these variables between winner and non-winner athletes. Fourteen men subjects were analyzed. Blood lactate concentration (LA) and heart rate (HR) were determined before and after the match. The match was filmed for the determination of the number of techniques used, the duration of effort and rest periods (RPs), and the interval between high-intensity movements (HM). Post-match LA was 7.5 +/- 3.8 mmol x L(-1), HR was 183 +/- 9 b.x min(-1), and HM was 31 +/- 16 seconds. The mean effort time (8 +/- 2 seconds) did not differ from mean interval time (8 +/- 3 seconds). Winners used a smaller total number of techniques, but post-match LA or HR did not differ from that of non-winners. In conclusion, the glycolytic metabolism was not the predominant energy source and the physiological responses did not differ between winners and non-winners. Coaches and sports scientists should prepare a technical or physical training session considering the low glycolytic contribution in this sport, hence the training protocol should involve high-intensity movements interspersed with longer RPs to provide the creatine phosphate recovery, with special attention given to the technical quality of TKD skills and not to higher technique volume during a simulation of matches.

              Relationship between attack and skipping in Taekwondo contests.

              The purpose of this study was to determine the relationship between attack time (AT) and skipping time (ST) during the 2007 Taekwondo World Championship and 2008 Beijing Olympic Games. A total of 22 matches (65 rounds, 13 semifinals, and 8 finals) from the World Championship and 23 matches (63 rounds, 22 rounds with 16 athletes each and 1 quarterfinal round) from the Olympic Games, both in the male category, were assessed using time-motion analysis. The AT was considered as the total time during which the athlete attacked or tried to attack, whereas ST was the total time without attempting to attack. The ratio of AT to ST was ∼ 1:7 based on the data pooled from the 2 competitions. The AT/ST ratio was significantly lower for the World Championship than for the Olympic Games (p ≤ 0.05). In the Olympic Games, no consistent differences across weight divisions were found. However, during the World Championship, the heavier weight divisions (>78 kg) exhibited a lower average AT, lower summed AT, lower attack numbers (ANs)and higher average ST than lighter weight divisions (<58 kg, p ≤ 0.05). For both competitions, the ST was lower, and the ANs and AT/ST ratio were higher in round 3 than in round 1 or 2. In conclusion, the results of this study suggest that matches in the Olympic Games were less cadenced than in the World Championship, but that in both competitions, the intensity of the match increased in round 3. Practically, these data suggest that coaches need to structure Taekwondo training sessions in a manner that allows the work/pause ratio to mirror the physical demand imposed during competitions.
