Onze lutas envolvendo treze atletas com 28.5 ± 3.7 anos que disputaram a categoria 1º. KYU até 65 kg foram investigados. A análise foi realizada por seis especialistas por meio da observação e registro de técnicas utilizando planilha tática e técnica de Scout de Karatê. O teste Anova foi utilizado para comparar as ações e técnicas mais utilizadas. O teste do qui-quadrado para amostras independentes foi utilizado para verificar a existência de diferenças significativas entre as técnicas utilizadas pelos atletas vencedores e derrotados (p<0.05). Os resultados mostram que o ataque mais frequente durante as lutas foi "Mawashi geri", 26.3 ± 1.5 vezes, seguido de "Gyaku zuki" com 19.5 ± 2.0 vezes (p<0.01). A ação tática mais visualizada durante os combates foi o ataque com 47.5 ± 5.5 vezes (p<0.01). “Mawashi geri” foi o ataque mais usado (p=0.01) pelos vencedores 71.4% quando comparado com os atletas derrotados 28.6%.

ABSTRACT The aim of the present study was to identify the most used techniques by medalists and defeated athletes during the Brazilian Shotokan Karate Championship of 2017. Eleven fights involving thirteen athletes (28.5±3.7yrs.) who competed in the category “up to 65 Kg 1 st KYU” were investigated. Analysis were conducted by six specialists through the observation and register technique using the tactical and technical spreadsheet Scout Karate. The Anova test was used to compare actions and techniques mostly used. The Chi-square test for independent samples was used to verify the existence of significant differences among the techniques used by the winning and defeated athletes (p<0.05). Results show that the most frequent attack during fights was the “Mawashi geri”, 26.3±1.5 times, followed by “Gyaku zuki” with 19.5±2.0 times (p<0.01). The most visualized tactical action during combats was the attack with 47.5±5.5 times (p<0.01). “Mawashi geri” was the mostly used attack (p=0.01) performed by winners (71.4%) when compared with the defeated athletes (28.6%). The results indicate that the “Mawashi geri” attack was the most assertive decision used in the category “up to 65 Kg 1 st KYU”. Keywords: Martial Arts. Karate. Analysis.
