Research On The Characteristics Of Technical And Tactical Of Three Chinese Female Athletes And Comparing The Characteristics Of The Champion Athletes’ In 2017 World Taekwondo Championships

In 2000,as Taekwondo was included in the Olympics as an official event,the development of females’ Taekwondo events in China ushered in a better momentum.China’s female Taekwondo team has won four gold medals in the Olympic Games and has been promoted to a world-class strong team.Female athletes of all divisions have demonstrated super competitiveness in the international arena.However,in the2017 World Taekwondo Championships,none of the Chinese players won the championship,and the results showed a landslide.Among the contestants,there was Zheng Shuyin,who won the championship in the 2016 Rio Olympics.In order to find the reasons for the decline in performance as soon as possible,this article specifically takes the technical and tactical characteristics of the three Chinese players Zheng Shuyin,Wei Xiaojing,Zhang Mengyu and their champions at the same division in the 2017 Taekwondo World Championship as the research object.The study used literature data method,video observation method,mathematical statistics method,expert interview method and other methods to analyze the data of their eliminated games and compare the technical and tactical characteristics of champions at the same division.Find out the key factors for the failure of our players and provide theoretical basis and data support for our women’s taekwondo coaches and athletes to prepare for the 2020 Tokyo Olympics and strive to achieve excellent results.The research conclusion is as follows:(1)The three Chinese Taekwondo female players have certain differences in the use of technology.The 53 kg division player Wei Xiaojing uses more side kicking technology,and the use rate of the back kicking technology is low but the success rate is high;the 67 kg division player Zhang Mengyu uses a single technique,but has a high score rate for side kick and cut down kick;the +73kg division player Zheng Shuyin is more comprehensive in the use of technology.The main scoring techniques used are turning kicking technique,side kicking technique and cut down kicking.(2)The three female Taekwondo players in China have slightly different tactical forms.The 53 kg division player Wei Xiaojing is good at using offensive and defensive counterattack tactics,and the counterattack tactics are used less and have poor effects.In the 67 kg division player Zhang Mengyu tactics,when facing the opponent’s attack,although the use rate of defensive counterattack tactics is high,the success rate is low;the +73kg division player Zheng Shuyin’s tactical application is relatively passive,showing the characteristics of being defensive.(3)Comparing the three female Taekwondo players in China with the champions of the same division,the comprehensiveness and effectiveness of the technical use of female Taekwondo athletes in China need to be improved,and the use of a single technology does not have an advantage in world-class high-level competition.(4)Compared with the tactical use of the three female Taekwondo players in China and champions of the same division,the defensive counter-attack ability is weak,and the flexibility and effectiveness of tactical use need to be improved.
