Research On The Effect Of Taekwondo Rules Change On Technical Use Of Athletes In 2018 Competition

Since Taekwondo has been listed as an official event of the Olympic Games,Taekwondo has developed rapidly all over the world,and it has been loved as a national fitness sport.As the lever and criterion of Taekwondo competition,competition rules play a guiding role in the competition and are the guidelines for the development of various techniques.Since 2000,competition rules have changed many times,and the types of techniques used by athletes will change after each change.Therefore,to study the influence of the changes of competition rules on the athletes' technical application,we can understand the development trend of Taekwondo technical movements,and provide theoretical help for athletes' training.By using the methods of documentation,expert interviews,video observation,mathematical statistics and logical analysis,this paper studies the application of Liu Kaiqi(-53kg),Li Chen(+73kg),Lin Wenye(-68kg),Renke(-74kg)and Chen Linglong(-87ke)in the first stage of the series of Taekwondo Championships in 2018 and in the final of the national championship of Taekwondo in 2018.Research on the influence of chemical industry on its technical application.The results show that the modification of Taekwondo rules has a great impact on the technical use of athletes.Among them,the number of push-kick techniques is greatly reduced,the number of front-kick techniques is slightly decreased,and the number of cross-kick,back-kick and boxing techniques is increased obviously.After the modification of the rules,the average total score of each game is reduced,but the straight-kick scores have been greatly improved,and the rotation.The average technical score and scoring rate of the players in each game decreased after the rules were amended.The total number of technical use,total score and total technical success rate of athletes in the winning game have been improved;the number of technical use of front horizontal kick,straight punch,hook kick,backspin kick,back horizontal kick,back kick and double flying kick has increased after the amendment of the rules,especially the number of use of front horizontal kick,backspin kick and straight kick has increased significantly;after the amendment of the rules,the ratio of athletes in the winning game has increased significantly.In the competition,the technical scores of downward splitting and straight boxing increased compared with before,and the scores of other techniques decreased in varying degrees,even the technical score of 0.After the rules were amended,the total score of each technique hit the head in the winning game decreased,but the percentage of the total score did not change much.The total number of technical use,total score and total technical success rate of athletes in winning games all decreased;the number of technical use of non-winning athletes in front horizontal kick,back horizontal kick,straight punch,back kick and back kick increased in varying degrees after the rules were amended;after the rules were amended,the average technical score of each non-winning game was 0,and the average score of each game was 0(except for fouls).Suggestions: 1.Strengthen all kinds of techniques further,improve the accuracy of all kinds of techniques,and improve the success rate of technicalactions.In addition,we should strengthen the training of turning kick technology,improve the quality of technical movements and make it more delicate.2.Strengthen physical fitness training,increase the intensity of physical fitness training,improve the speed and intensity of movement,so as to ensure the quality of movement completion.Starting in 2018,the National Taekwondo Championship is a series of four matches and a championship finals.The competition arrangement is intensive throughout the year.Good physical fitness is the key to win the competition.At the same time,scientific and reasonable selection of physical recovery means is necessary.3.Enrich the means of attack and defense,strengthen the ability of each special skill,make it have more choice of attack and defense in the competition,and ensure the comprehensive development of its technology.4.Strengthen skill combination exercises to make athletes possess both offensive and defensive abilities,and increase the diversity of offensive means of athletes.In particular,the training of the combination of continuous offensive techniques and the combination of continuous counter-offensive techniques can improve the continuity and coherence of their own offensive and defensive techniques and constantly oppress the opponents' scores.The reasonable combination of defensive technology and attack technology can improve the success rate of defensive counterattack tactics.5.Strengthen the training of head-hitting techniques,improve the accuracy and intensity of their head-hitting technical actions,and try more head-hitting exercises with different technical actions,so that they have more choice of head-hitting techniques in the competition,increase the difficulty of their opponents' defense,keep their opponents on high alert at all times,dare not launch attacks easily,so as to alleviate their pressure.6.Strengthen the training of effective scoring of boxing techniques.In order to make the competition more intense and ornamental,Taekwondo encourages athletes to use boxing techniques reasonably in attacking opponents and scoring points,rather than just for defense.Learn and draw lessons from the direct boxing techniques of Sanda and Boxing,integrate and improve their scoring techniques.Although the punching technique has a small punching intensity,it has a high flexibility,small movements and easy control.Increasing the punching attack in the competition may have an unexpected effect.7.Strengthen athletes' understanding of foul behavior,constantly strengthen athletes' correct competition behavior in daily training,and try to avoid foul behavior.Only by strictly demanding oneself with higher behavior in training can one reduce the occurrence of his foul behavior in competition.
