Bivariate analysis of taekwondo actions: The effectiveness of techniques and tactics in an Olympic taekwondo championship.
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…
Perfil de habilidades psicológicas en taekwondistas universitarios y su relación con el éxito en competición
Se presenta el perfil de habilidades psicológicas y su poder predictivo sobre el éxito deportivo en taekwondistas universitarios de competición. Para ello se evaluó una muestra representativa de 89 taekwondistas (50 hombres y 39 mujeres) con edades entre 18 y 34 años (M = 22,2; DT = 3,34) que competían en el Campeonato de España Universitario 2011. Se les administró el Inventario Psicológico de Ejecución Deportiva (IPED) y se tomó como variable de éxito deportivo el número de combates ganados durante el campeonato.

Technical-Tactical Actions Used to Score in Taekwondo: An Analysis of Two Medalists in Two Olympic Championships
Research in taekwondo has traditionally focused on specific aspects athletes' overall technical and tactical skills, while ignoring other important issues such as identifying how successful athletes score points. The aim of the current study was to follow two medalists through two Olympic Championships (2012 and 2016) to discover the effective patterns associated with scoring in taekwondo using an observational methodology. An ad-hoc taekwondo observational tool was used to codify the actions performed by the athletes. An observational descriptive and multivariate analysis of 1,688 actions performed by the athletes was conducted. A lag sequential and polar coordinate analysis was performed …
Tactical Aspects of a National University Taekwondo Championship in Relation to Round and Match Outcome
The aims of this study were to analyze tactical behavior (direct attacks and indirect attacks, in addition to anticipatory, simultaneous, and posterior counterattacks) according to competition round and match, and to compare tactics of competitors (winners and nonwinners) in a university taekwondo championship. The analysis included 334 individual performances from 204 athletes over 169 bouts in the National University Championship. A 2-way repeated measure analysis of variance was conducted with “round” (at 3 levels: first, second, and third) as the within-subject factor and match outcome (at 2 levels: winning and nonwinning) as the between-subject factor. The results of this study show th…
Generalizability Theory Applied to Olympic Male Taekwondo Combats
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…
Is It Possible to Predict an Athlete’s Behavior? The Use of Polar Coordinates to Identify Key Patterns in Taekwondo
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…
Task and Ego Orientation in Sport Questionnaire (TEOSQ): Psychometric properties in its digital version
The Task and Ego Orientation in Sport Questionnaire’s (TEOSQ’s) psychometric properties have been explored in previous studies but never in its digital version, which facilitates data collection. The objective of this study was to analyze the psychometric properties of the online TEOSQ by MenPas 1.0. The sample was composed of 2320 users (58.4% women; 41.6% men), between 18 and 65 years old (M = 25.27, SD = 7.39). The methods used were Confirmatory Factor Analysis (CFA) and invariance analysis from the original 13-item model. The CFA was corrected for all samples (CFI = 0.92–0.94, TLI = 0.93–0.95, RMSEA = 0.07, SRMR = 0.06; df = 64; Bollen-Stine Bootstrap p = 0.02–0.07): general sample (χ2 …

Analysis of different key behavioral patterns to score in elite taekwondoists according to the weight category and gender
Traditionally, research in taekwondo has focused on athletes' overall performance considering the entire sample of the tournament or analyzed selected bouts while ignoring behavioral differences of athletes according to their gender and weight category. Thus, the aim of this study was to analyze the behavioral patterns used to score points in the London Olympic Games according to gender and weight category [fin (FW), feather (FTW), light (LW), and heavy (HW)] of the athletes. A total of 24,940 actions were analyzed by using observational methodology, a mixed method methodology where lag sequential and polar coordinate analysis were applied. Different patterns could be seen in the actions pe…
Tactical Analysis of the Winners' and Non-Winners' Performances in a Taekwondo University Championship
The purpose of this study was to identify tactical characteristics of successful athletes who competed in a National University Championship. Results from the study allow taekwondo coaches and competitors to orient their training towards evidence-based practice to achieve success in competitions. Overall, taekwondo athletes performed more attacks than counterattacks. However, winners performed more counterattacks than non-winners. Moreover, winners performed more anticipatory counterattacks (ANC) and less indirect attacks (INA) than non-winners. Lastly, the order of the performance of the actions for non-winners was by decreasing frequency direct attack (DIA), INA, posterior counterattack …
