The Comparative Analysis Of Valid Points And Technology Enable Of Men Taekwondo At Different Weight Categories And Periods Under The New Rules

Changes in rules will inevitably affect the development of technology.Sports competition rules are the benchmark of the game.Ignoring the importance of the rule s will inevitably bring about adver se effects.The revision of the new rules has significantly modified the technical score and foul behavior of the game.We must pay great attention to it.Scoring is the only criterion for evaluating the use of competition technology.A comparative analysi s and research of the effective scoring methods for men's Taekwondo at different l evels and at different times during the 2019 World Championships will help us recognize the trend of scoring techniques for high-level male athletes in the world after the rules are modified.In this paper,through literature data method,video statistics method,expert interview method,mathematical statistics method,and comparative analysis method,the main points and effective scores of m ale athletes in different periods a nd different levels are compared and analyzed to find out the current men's Taekwondo scoring techniques in different periods.Changes and the use of major scoring techniques.The following conclusions are reached through research and analysis:(1)Under the new rules,the effective scores of small-level athletes in the same level and different periods of time for male taekwondo athletes continue to decline,and the change range is obvious,which has a greater impact on the 2-point and 3-point scores;The downward trend has a small change range;the effective scores of large-level athletes show a continuously rising change characteristic,and the scores have a large change range.(2)Under the new rules,among the different levels of male Taekwondo athletes in the same period,the effective scores of small-level athletes in the opening period dominate;the effective scores of all levels in the intermediate period are similar;the effective scores of large-level athletes in the final period dominate.(3)In the application of techniques for athletes of different levels under the new rules,athletes at different levels mainly use high-level horizontal kicking techniques and undercutting techniques;mid-level athletes mainly use horizontal kicking techniques;large-level athletes use lateral kicking techniques and undercutting techniques Mainl y.(4)Among the effective scoring abilities of different tec hniques under the new rules,the horizontal scoring technique and the undercut technique have the best scoring ability,the straight scoring technique has the better scoring ability,and the side kicking technique has a poor scoring ability.
