Analysis On The Application Of Technique And Tactics Of Women Taekwondo-57kg Athletes In Tokyo Olympic Games

Women’s 57 kg Taekwondo became an official event of the Asian Games in 1998.The Chinese Taekwondo team did not finish second in the sport until the 2012 London Olympics,filling a gap in the history of the Chinese team at that level.In the following years,although Chinese women 57 kg Taekwondo athletes have made good achievements in various world competitions,but in the Tokyo Olympic Games women’s-57 kg Taekwondo competition,Chinese athletes ended up in the top eight by one point unfortunately,which shown that there is still a gap between Chinese women athletes and the world elite athletes.In this paper,the characteristics of the women Taekwondo athletes of-57 kg class in Tokyo Olympic Games were taken as the research object,and the methods of literature data,mathematical statistics,video analysis and logic analysis were adopted.This paper selected 20 videos of women’s Taekwondo in Tokyo Olympic Games,including 1/8 final,1/4 final,semifinal,Revitalizing competition,bronze medal competition and gold medal competition,and made statistical and analysis on the techniques and tactics used by athletes in the competition,aimed at clarifying the characteristics of women’s Taekwondo athletes in Tokyo Olympic Games of-57 kg.It provided some reference for Chinese women Taekwondo athletes to prepare for the 2024 Paris Olympic Games.Among the findings:(1)From the perspective of standing frames,it is found through data statistics that the athletes using closed standing frames account for a small number,mainly open standing frames.The highest scoring rate of open stand is the hind leg cross kick and the highest success rate is the front leg hook kick.The highest scoring rate of the closed stand is the rear leg cross kick and the front leg side kick.Secondly,the use of the rotary "back kick" technology will have a surprise effect,so it has a higher success rate.Among the techniques used,the front leg cross kick,the back leg cross kick and the front leg push kick are the core of the techniques,which are supplemented with other offensive techniques.The athletes have flexible and fast technology transformation.(2)In the attack,meeting the attack and counterattack of Taekwondo competition,footwork combined with leg method has a high success rate.Athletes mainly use footwork to dodge,close up and parry defense.They use footwork to dodge or lean against the opponent’s attack in the middle and long distance contact.Footwork technology also provides cover for defense and recovery after kicking,thus improving the performance of athletes in the game.(3)Among the combination techniques,the highest utilization rate and scoring rate of the combination techniques are “back hand punch+ hind leg cross kick and front leg cross kick +back hand punch” of the open standing frame and “front leg cross kick + back hand kick +hind leg cross kick” of the closed standing frame,forming a scoring mode dominated by straight fist.In the combination of leg methods,the open stand is dominated by “front leg cross kick + hind leg cross kick”,while the closed stand is dominated by “front leg cross kick+ up leg cross kick”.In line changing technology,the open station frame line changing technology is the high use of “middle to middle”,front leg cross kick change front leg cross kick technology score rate is the highest.The technique of line change on the closed stand is mainly “medium to medium”,and the scoring rate of “front leg cross kick to front leg cross kick” is the highest.In the competition,it is also found that line changing technology has become a high frequency of use by athletes all over the world,and gradually become a new scoring technology system.(4)In the aspect of "hitting position",the number of hits in the middle position is more than that in the high position,but the scoring rate of the high is higher.In the competition,the middle technique is the main technique,and the application of high technique is based on the middle technique.In order to encourage athletes to use more high technology in competition,the new rules say that the impact value of electronic helmets should be reduced to contact,and athletes use high position skills has become an inevitable trend.(5)In the use of tactics,offensive tactics are used most,followed by attacking tactics,counter-attacking tactics,and defensive tactics.It can be found from the game video that athletes have a strong pertinence in the use of tactics in the game.They can choose reasonable and effective tactics according to the characteristics of different opponents and the change of the situation on the field,and strengthen the effect of the use of tactics.In order to promote the technical and tactical level improvement and development of Chinese women’s 57 kg Taekwondo event,the following suggestions are put forward.(1)In terms of standing frame,it is suggested that athletes should carry out systematic exercises in the subsequent training.They should be proficient in the left open position and right open position,the left closed position and the right closed position,and switch the Angle of standing position through the exchange of footwork.It is suggested that athletes should strengthen the application of multi-direction technique of front leg straight and arc and hind leg combination technique in open stand.The athletes in the closed stand should focus on the technique of lifting the front leg and kicking and rotating the back leg.Secondly,boxing technique is not only an offensive means but also a defensive sword.It can effectively cooperate with various techniques and tactics to increase the use of boxing technique in the match,so as to achieve the effect of 1+1 > 2.(2)Taekwondo footwork is crucial to the attack and defense of athletes.It is necessary to strengthen athletes’ understanding of changing rhythm in the application of techniques,establish the awareness of “changing rhythm”,and let athletes know that only by skillfully using fast and flexible footwork can they master fast and flexible tactics.(3)In the combination technique,“fist technique+ leg technique” has already occupied a place in the technical system of Taekwondo,which should be consolidated and improved in daily training.Secondly,in the combination technique of leg method,we should not only pay attention to improve the fluency of leg method transformation,but also pay attention to the scoring efficiency of high technique and rotation technique in the combination of leg method,such as "front leg cross kick + hind leg cross kick".Under the condition that the competition rules of Taekwondo are constantly changing,the understanding of technical movements should be strengthened and the technical system should be continuously enriched,such as the secondary strike technique,line changing technique,leg-controlled strike and continuous and effective single-leg attack.On the premise of ensuring the medium technique,it is necessary to properly improve the utilization rate of high technique,enrich the usage mode of high technique,effectively use the corresponding technique against opponents of different height and style,and pay attention to training the awareness of athletes to hit the head.(4)In terms of tactics,it is very important to control the rhythm of the game.With the continuous development of competitive sports,athletes should actively attack,seize the initiative,but also to see the opponent’s tactical use,pay attention to the control of attack rhythm.Timely use of offensive tactics,control the rhythm of the game,in peacetime training athletes should be more with different tactical characteristics of the players against the practice,the formation of a diversified tactical mode.
