Study On The Construction Of Special Physical Fitness Index System Of Young Women 800 Meter Runners In Hubei Province

The 800 meter race is a typical periodic physical fitness dominated race,which requires athletes to have good special physical quality.The selection and training of teenagers is an important part of cultivating competitive sports reserve talents and the basic part of improving the competitive level of 800 meter running.In recent years,the level of world middle distance running has been continuously improved,while the sports performance of 800 meter events in China has developed slowly.Therefore,if we want to further improve the performance of women’s 800 m running in China,we should pay attention to the training of teenagers and deeply analyze the impact of teenagers’ special physical quality indicators on sports performance.This study uses the methods of literature,expert interview,expert questionnaire,test and mathematical statistics to conduct qualitative and quantitative research on 40 young women800 m runners aged 15-17 in Hubei Province: 1.Evaluate and determine the indicators of two rounds of questionnaires issued by experts;2.Factor analysis of the selected special physical fitness indicators;3.Grey correlation analysis and weight analysis were carried out between special physical fitness indicators and special achievements;4.Predict and analyze the special results of 800 meters.The following conclusions are drawn:（1）Through empirical analysis,the special physical fitness index system constructed in this study can more accurately reflect the relationship between the special physical fitness of800 meter race and the special performance,and can detect the development level of athletes’ physical fitness.Therefore,the construction of this index system is scientific and effective.（2）The special physical fitness index system of young female 800 m runners in Hubei Province is composed of four main factors: speed endurance factor,special speed factor,special strength factor and special endurance factor;A total of 11 typical indicators: 400 meter run,600 meter run,300 meter run,60 meter run,100 meter run,200 meter run,barbell weight-bearing squat,standing triple jump,100 meter step jump,1000 meter run and 3000 meter run.（3）According to the special physical fitness index,the grey correlation degree and weight value of 800 meter results are sorted in order: 600 meter run > 400 meter run > 1000 meter run > 200 meter run > 100 meter run > 300 meter run > 3000 meter run > 60 meter run > standing triple jump > 100 meter step jump > barbell weight-bearing squat.（4）Through the regression analysis of the three indexes of women’s 800 meter running and 400 meter running in Hubei Province,the final regression equation of women’s 400 meter running is obtained:Y = 40.694 + 0.122×400M + 0.498×600M + 0.269×1000M（5）The weight of each factor in this index system is relatively balanced.It can be concluded that the special quality of youth 800 m running can not be improved only by the development of a certain physical quality,but requires the joint development of four special physical qualities: speed endurance,special speed,special strength and general endurance,so as to achieve the purpose of improving special results.
