Abstract

RESUMOO objetivo do presente estudo foi identificar as técnicas mais utilizadas por medalhistas e atletas derrotados durante o Campeonato Brasileiro de Karatê Shotokan de 2017. 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%. Em conclusão o ataque "Mawashi geri" foi a decisão mais assertiva usada na categoria até 65 Kg. Palavras-chave: Artes Marciais. Karatê. Análise. ABSTRACTThe 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".

Identifying Keys to Win in the World Karate Championship

“…This is in accordance with the research by Pitter Laird and Koropanovski which showed that the Gia Kuzuki technique was the highest-scoring technique (2,13) and with the research by Alinaghipour which found kizama zuki technique as the most scoring technique (14). Also, our research results are contrary to those found by Romanovitch, who found mawashi geri technique as the most applicable technique (18). In this research, kizama zuki had the highest frequency among the techniques studied, but the ratio of repetition of this technique to its scoring is in the third rank.…”

Changes of physical capabilities of muscular strength, power and flexibility in a karate competition

“…In high-level karate athletes, the use of punches is more commonly observed, thus, resulting in a greater potential for fatigue (Loturco et Petrov et al, 2018;ACMS, 2012, Tabben et al, 2015. On the other hand, other researchers found that the most frequent attack used by Brazilian National karate athletes was the semi-circular kick with the leg positioned behind (lower limb) (Ribas et al, 2020). Unfortunately, we did not determine the number of kicks and punches during each kumite fight to establish a comparison with these investigations.…”

“…Karate is an ancient martial art practiced by around 100 million people worldwide (Martínez et al, 2020). In karate competitions, the modalities used are kata and Shiai kumite, requiring athletes to possess physical and motor skills to perform different movements, such as punches, strikes, and kicks (Ribas et al, 2020;Voltarelli et al, 2009). During a kumite fight, movements need to be performed at maximum speed, ensuring that the attacker's hand or foot reaches the target without the opponent being able to respond (Przybylski, et al, 2021).…”

Augmented Reality Training on Combat Sport: Improving the Quality of Physical Fitness and Technical Performance of Young Athletes

“…Technical performance is related to the quality of attacking movements such as punches and kicks to blocks and defensive locks (Barley & Harms, 2021). Improving technical skills could support athletes to gain high performance, and has a great chance to win the com-petition (Ribas et al, 2020). Data from a previous study reported that in combat sports competition, athletes must carry out motoric actions in attacking and defending for 3 rounds of 5 minutes each, which means that the quality of technical performance is a crucial factor (Folhes et al, 2023;Manolachi et al, 2023).…”
