Resumo

As regras de competição do taekwondo passaram por profundas transformações entre 2012 e 2026, impulsionadas pela necessidade de maior transparência e de aumentar o apelo para os espectadores. Este estudo analisou a evolução regulatória do taekwondo e seu impacto na dinâmica das lutas e no desempenho. Para isso, foram revisados documentos oficiais da World Taekwondo e a literatura científica, com o objetivo de sintetizar as mudanças nos sistemas de pontuação, nas tecnologias utilizadas e na estrutura dos combates. Os principais resultados indicaram que essa evolução foi marcada pela implementação progressiva do Sistema Eletrônico de Pontuação (Protector Scoring System –PSS), que se expandiu do uso exclusivo no protetor de tronco em 2012 para a inclusão de sensores no capacete e nas meias em 2017. A reforma de 2022 introduziu o sistema “melhor de três”, com reinicialização da pontuação a cada round e limite de cinco gam-jeom (penalidades) por round. Em 2026, novas atualizações incorporaram luvas com sensores para os socos e uma “Área de Advertência” de 60 cm para controle espacial. As reformas no sistema de pontuação aumentaram o valor de técnicas complexas, como o chute giratório na cabeça, que passou a valer seis pontos em 2026. O sistema de penalidades evoluiu de um limite de 10 penalidades para desclassificação (2017) para a perda automática do round ao atingir cinco penalidades (2022). Mudanças estruturais incluíram a adoção de áreas octogonais e a simplificação da Revisão Imediata de Video, com a retirada da revisão de chutes na cabeça quando o PSS é utilizado (2026). A análise da literatura científica indica que essas alterações regulatórias aumentaram a intensidade dos combates, com estudos relatando elevação dos níveis de lactato pós-luta e maiores exigências cinemáticas, obrigando os atletas a adotarem estratégias técnico-táticas mais ofensivas. Conclui-se que a trajetória regulatória modernizou o taekwondo, tornando-o um esporte mais dinâmico, tecnologicamente avançado e fisicamente exigente. A adoção da pontuação independente por round e as atualizações de 2026 priorizam o desempenho explosivo e a clareza para o público, exigindo que os protocolos de treinamento sejam adaptados às maiores demandas anaeróbias e estratégicas.
