Construction Of The Index System Of Teenager Women’s 400 Meters Hurdles Athlete’ Physical Quality

There is a certain gap in the overall level of women’s 400 metershurdles in China at present, compared with the high- level athletes in the world,shown in detail as short duration of the absolute speed of the athletes, poor in speedendurance and lack of stamina, these physical quality gaps restricted to furtherimprove of the women’s 400 meters hurdles. The high level of physical training is animportant prerequisite to improve athletic performance of the 400 meters hurdles. Thesystem constructed to reflect the 400-meter hurdler physical indicator system is thekey to test the quality of training effectiveness and improve athletic performance andscientific evaluation. Any sport to make a breakthrough, we must start from thefoundation and pay attention to the cultivation of young reserve talents, 400m hurdlesis no exception. This has a very important practical significance that making scientificindex system of physical quality for teenager to assess the validity of the physicaltraining method.In this study, Liaoning Province for example, by using the methods ofdocumentation, the Delphi method, testing method, factor analysis, regressionanalysis and correlation analysis, through deeply analysis the typical indicatorsreflecting the fitness level of the teenager women’s 400 meters hurdles athletes,analysis the relationship between the typical indicators and athletic performance,construct the index system. According to the typical indexes, set up correspondingperformance prediction model to feedback the training effect, through the comparisonof predicted results with actual results, to identify the deficiencies in the stage oftraining, in order to purpose of controlling training and improving the training effect.Through researching, conclusions are as follows:1. Teenager women’s 400 meters hurdles athletes’ physical qualities index systemconsist of 7 typical indexes, they are: 100m, starting to the 8thhurdle, 500m, oneminute clip arm push-ups, 30 seconds of sit-ups, horizontal cross, vertical fork.2. The effects to the 400m hurdles result of the 7 typical indexes size in order: startingto the 8thhurdle> one minute clip arm push-ups>100m>500m> vertical fork>30seconds of sit-ups> horizontal cross. 3. Teenager women’s 400 meters hurdles athletes’ performance prediction model is:Y=4.972+1.365X1(starting to the 8thhurdle)-0.059X3(one minute clip arm push-ups).
