A Study On The Characteristics Of Training Load Of Male 400-metre Runners In Hunan Province In The Race Period

With the development and change of competitive sports in colleges and universities in China,the level of the men's 400-meter run is constantly improving.At home and abroad,researchers have studied the training methods and methods of different competitions,but there are not many literatures on the training of the 400-meter race in the present research.In order to meet the needs of theory and practice,it is of great value to study the characteristics of the training load of the high level athletes of the 400-meter running project in China,which reaches the national level of the male 400-meter runner.This paper studies the characteristics of the training load of the men's 400-meter runners in the 2017 National student games in Hunan province,and sums up the characteristics of the training load in the competition period from the training angle of view,from the athletes ' achievements,physiological function and other aspects of the national level athletes have to explore the competitive training load characteristics of the effect of the optimal regulation,for the General University of our province in the 400-meter race training load characteristics of the competition to summarize the successful experience,in order to effectively improve the average university men's 400-meter runners to provide practical guidance Provide necessary theoretical support for scientific training athletes.In this study,6 male athletes of 400-meter runners in Hunan province with national level are regarded as the object of observation.By using the methods of literature,expert interview,tracking and observation,measurement and mathematical statistics,the paper sums up the effect of the arrangement of training load on athlete's performance and physiology function during the competition period,The load characteristics of each stage of the competition are analyzed.The results show that the training of male 400-meter runners in Hunan province is usually 8 weeks,and the training is divided into three time periods.The training load arrangement for the three stages of the competition period is as follows:the first stage(training 1-4 week)is the intensive training stage,Through the increase of load and load intensity,the general ability and special athletic ability of the athlete are developed,so that the training load and the load intensity are close to the athlete's limit.The second stage(training reserved week)is to consolidate the training stage,is the period of setting up and maintaining the athlete's training performance,mainly to consolidate the athlete's speed,speed endurance and special ability,strengthen the athlete's strength and other body training level,and make the athlete transform from high load and high intensity training to the link of The third stage(training 7-8 weeks)is the pre-competition adjustment stage,it is the stage that the athlete transforms from the middle and high load training state to the competition state from the first two stages of the competition,to release the psychological pressure for the athlete,to impel the athlete to enter the athletics condition better,to eliminate the physical and psychological fatigue of the athlete,To achieve the training effect of competition.This kind of training load pattern frame has remarkable effect on consolidating ability level,improving athletic state,shortening the generation time of anaerobic glycolysis system,slowing the energy supply speed,elevating and lactic acid and eliminating lactic acid ability of anaerobic metabolic system.
