WA Comparative Study On The Change Of Whole Speed Of Chinese And Foreign Elite Male 400m Hurdlers

With the development of competitive sports and the improvement of the level,modern sports training is more and more emphasis on the importance of directional special training."Special training" from the perspective of exercise physiology can be interpreted as the arrangement of the training all obey the requirements of the competition,training intensity,energy supply,nerve-muscle work and other aspects to keep consistent with the game.At the same time,studies have shown that the formal special,in fact,non-specific training for those who in particular short distance,fast,with anaerobic energy-based energy projects more dangerous.All of this makes it necessary for us to clearly determine the kinematic and physical aspects of the 400 m hurdle.The 400 m hurdle race belongs to the cyclical racing project according to the theory of the group training theory.The ability of displacement speed is the main reason to decide the level of the project.Throughout the years 400 m hurdle performance changes,we can see,400 m hurdles race is the key to speed.According to the information reported in the world of outstanding men’s 400 m hurdles 100 m athletes in 10 seconds 3 seconds,indicating that the absolute speed is the key to its success.The famous sprinter trainer Ogorokov has proved the important role of many parameters in the 400 m hurdles after a long period of study.It is considered that the athlete’s sprint ability is an important factor to improve the performance of the 400 m hurdles.China’s track and field training because of the characteristics of energy supply and project classification in the deviation,once thought that 400 m run training should be based on speed endurance,speed,supplemented by the guiding ideology,the results of athletes speed difference,speed endurance in general,and poor special performance situation.With the continuous development of sports training theory,people have a new understanding of 400 m hurdle training,modern 400 m hurdle training from the traditional training volume to focus on training intensity as the center of the importance of speed quality training.A large number of studies confirmed that the 400 m hurdles race full speed distribution model is an important factor in achieving excellent results.In fact the 400 m hurdle is a constant combination of ever-changing dynamic processes.This constant combination and varying gait has a very important impact on the speed structure of the 400 m hurdle.Therefore,it is of great significance to improve the performance of the 400 m race by exploring the law of the whole speed change in 400 m running.In this paper,using the literature data,video analysis,foreign men’s 400 m hurdles full range of speed changes in the study,in order to improve the overall level of China’s 400 m hurdle to provide theoretical and practical reference.The results show that:(1)There is a certain gap between the 400 m hurdlers and the world elite athletes.Domestic athletes in their own speed level is limited,the lack of control of the first half of the speed,resulting in the second half of the speed drop too much,is not conducive to their own speed level of play.(2)The number of steps between the two columns in the number of steps between the domestic elite athletes than the international elite athletes in advance,and the increase in the number of steps while the frequency is also declining,which is the second half of the speed and international Group gap between the main reason.(3)Cheng Wen in the ability to run flat,speed control and speed to maintain the ability of foreign athletes there is a big gap.(4)400-meter hurdle is the speed of the project,the development of absolute speed is to increase the speed of the key 400 meters hurdles.(5)to improve the speed of 400 meters is a 400-meter hurdles the main means of training athletes.
