Research On The Competitive Performance Characteristics Of Domestic Outstanding Men's Long-distance Jumpers

This study selected the competitive performance of the top 8athletes in the total number of 48 athletes in the 31 st Olympic Games in 2016,the13 th National Games in 2017 and the finals in the 16 th Track and Field World Championships in 2017.The results of competition are the main sources of data,through literature,mathematical statistics,logical analysis,expert interviews,comparative analysis,and other methods,using the coefficient of variation,rate of play,best score distribution,success rate,mean value,and final score difference It only reflects the characteristics of competitive performance of domestic elite male long-jump athletes in the three major competitions,and analyzes the factors that affect athletic performance.The aim is to grasp the essential characteristics of competitive performances of domestic elite male long-jumping athletes in the competition,and to develop training programs and entry plans for domestic athletes to suit the individual characteristics of the athletes in order to promote the best competitive level and create outstanding results.,with theoretical reference and practical application value.research shows:(1)At the National Games,the stability and efficiency of the triple jump is better than that of the long jump.In terms of the long-distance stability of the Chinese athletes in different competitions,the Olympics and the World Championships are better than the National Games,and the rate of play is the opposite.Individual athletes can play stably.On the other hand,there is no specific law for the stability of the triple jump,and the Olympic Games and World Championships play better than the National Games;there is no obvious difference between the stability and the rate of play and foreign competitors.Although competitive performance of domestic athletes in individual competitions is relatively stable and has the strength to compete for the cards,there are widespread individual differences among athletes,and overall,they are low level steady play.(2)Domestic long jumpers did not create the best results in the first and sixth rounds of jumps,but in the second to fifth rounds of jumps,the first three jumps were higher than the last three jumps,and the best performances of the overseas long jumpers were distributed in each.There are different rules in the jump times and the first three jumps and the last three jumps are nearly equal.The best scores of domestic and foreign triple jumps are mainly distributed in the first three hops and are far more common than the three hops.(3)In the long jump,the success rate of the first three rounds of domestic athletes is greater than the last three rounds.In the triple jump,there is no significant change in the success rate in the first three rounds,and the success rate is high.As a whole,compared with foreign countries,the long-term foreign success rate is slightly higher and there is a certain gap.On the contrary,the success rate of triple jump is better than that of foreign countries.(4)The difference between the average and the final scores of the athletes at home and abroad in the long jump is relatively small,indicating that the overall competitive performance of domestic and foreign athletes is a relatively controllable common characteristic.In addition to a large gap between individual athletes,competitive performance is more difficult to control.(5)Competitive factors and non-competitive factors are the key factors that affect the competitive performance of domestic elite men’s long jump athletes.
