Study On The Physical Characteristics Of Chinese Excellent Karate Kumite Male Athletes

After Karate has developed into a formal event of the Olympic Games,investment from all over the world has increased,make the project more competitive.China's karate movement started late,men's karate did not perform well in preparation for the Tokyo Olympic Games,low physical fitness is one of the important factors restricting the development of karate in China,and the research on the physical characteristics of athletes is the breakthrough to solve their physical problems.This research adopts the methods of literature,expert interview,questionnaire,test,mathematical statistics and logical analysis,guided by the event-group theory and the Sports Training Theory,based on the investigation of karate coaches and referees in China,and the test of 17 excellent male karate athletes in China,analyzed the physical characteristics of excellent male karate athletes,the purpose is to build a relatively complete,targeted and operable physical evaluation system for elite male karate athletes,it can provide a reference standard for the quantitative evaluation of the physical development level of China's elite male karate athletes,to carry out the diagnosis and evaluation of the physical fitness level of China's elite male karate athletes,understand the advantages and disadvantages of athletes in physical development level,to provide guidance the future physical training.The basic conclusions are as follows:1.In terms of body shape,China's top male karate athletes are tall,long limbs,the distance between fingers is longer than the height,shoulder width,the upper arm has a large circumference,the waist hip ratio is reasonable,the proportion of fat is small,and the physical enrichment.2.In terms of physical fitness,China's top male karate athletes have strong movement response speed,has fast start-up speed,movement speed and movement speed with accurate sense of space,able to control the strength and hit the target quickly and accurately,coordination,sensitivity and core strength are outstanding,and has strong special endurance.3.In terms of physical skills,China's elite male karate athletes have strong anaerobic metabolism,aerobic metabolism is good,the utilization rate of maximum oxygen uptake is high,lactic acid is eliminated quickly,strong resilience.4.Using literature retrieval and expert interviews,Delphi method,factor analysis and other methods,established the physical fitness evaluation index system,and constructed the evaluation model of physical structure,it includes three elements,including body shape,body quality and body function,and a total of 10 common factors,the weights of different elements and common factors are defined,the corresponding scoring standard and rating standard have been established.5.The physical fitness evaluation system constructed by the Institute,it can directly,clearly and scientifically evaluate the physical fitness level of excellent male karate athletes,understand the advantages of each athlete's physical structure,it reflects the common characteristics and problems of physical fitness level of excellent male karate athletes,to realize the effective diagnosis and evaluation of athletes' physical fitness,the results can be used as a reference for the physical characteristics of Chinese elite male karate athletes.
