Resumo(s)
O objetivo desta dissertação foi estudar a dinâmica ecológica da tomada de decisão no judo. A compreensão da performance no judo tem seguido modelos de processamento de informação, assumindo decisões “corretas” e pré-determinadas, mas negligenciado a interação dos judocas ao longo do combate. Em alternativa, a dinâmica ecológica enfatiza a coordenação do sistema judoca-judoca, na qual a decisão de atacar emerge da concretização de affordances que os atletas oferecem mutuamente e percecionam diretamente, expressando-se por transições na coordenação do movimento interpessoal. Tecnologias weareable permitem medir este movimento e consequente coordenação em situações de combate. A presente dissertação começa for rever a literatura sobre a tomada de decisão no desporto. Depois, apresenta um estudo metodológico preliminar para validar um sistema inercial. A seguir, descreve um estudo experimental que analisou a dinâmica da tomada de decisão no judo, concluindo que o ataque pode ser modelado por transições na coordenação interpessoal promovidas por desalinhamentos na orientação corporal relativa que possibilitam atacar. Finalmente, discute como a decisão neste desporto é um fenómeno corpóreo e situado, hipotisando que a perícia implica atuar intencionalmente na meta-estabilidade. Esta dissertação informa o treino no judo, nomeadamente o desenho de tarefas centradas em affordances para projetar e na perceção-ação .
The purpose of this dissertation was to study the ecological dynamics of decision-making in judo. The understanding of judo performance has followed information-processing models, which assume "correct" and pre-determined decisions, but neglect how judokas interact throughout the combat. Alternatively, ecological dynamics emphasizes the judoka-judoka system's coordination, in which attacking decisions emerge from actualizing affordances that athletes mutually offer and directly perceive, being expressed via transitions in interpersonal movement coordination. Wearable technologies allow measuring such interpersonal movement and further coordination in combat situations. This dissertation begins by reviewing the literature on decision-making in sport. It then introduces a preliminary methodological study to validate an inertial system. Next, this dissertation reports an experimental study to analyze the dynamics of decision-making in judo, concluding that attacking decisions can be modeled as transitions between interpersonal coordination driven by relative body orientation misalignments that create throwing affordances. Finally, this dissertation discusses how judo decision-making is an embodied and situated phenomenon, hypothesizing that expertise entails intentionally performing in meta-stability. This dissertation informs judo training, namely designing tasks focusing on throwing affordances and perception-action processes.
