摘要:Taekwondo competition underwent enormous development with the recent introduction of electronic scoring devices and rule changes. Although the competitive model of taekwondo had been previously studied, most of the literature that analyses this model was previous to the introduction of electronic devices or not based on a prior system of categories. Not only are results of an up-to-date taxonomy essential to guarantee the sustainability of future research about taekwondo based on methodological observation, but they are also completely necessary. This article proposes and validates a new categorisation of taekwondoist technical–tactical actions in the competition after the modifications were introduced between Beijing 2008 and Tokyo 2021 qualification events. The association between environmental conditions, tactical objectives, and technical actions determines the defining parameters of the combat situations. To design the category system, a dual methodology was used: in the first stage, an in-depth review of the technical and scientific literature based on observation of combats was carried out. From that review, a synthesis document was produced, which subsequently was used as a basis for canvassing an up-to-date view of the question from expert advisers. The existing terminology and categories were rearranged and updated, establishing new parameters involved in the technical–tactical resources of contest situations. This updated categorisation was tested by using the generalisability theory, revealing excellent-to-perfect observers’ agreement and reliable data. This new categorisation will allow designing precise and sustainable tools over time for methodological observation of taekwondo in future studies.
