The Research Of Physical Ability St Ructure Features And Construction Of Evaluation Standard For 15-16 Year-old Outstanding Javelin Thro Wers In Zhejiang Province

In today's increasingly competitive track and field events,each project has minimal level of technical differences in the operation,the situation only rely on technical superiority to win the race to offer more to see,in the case of technology can not widen the gap,fitness pros and cons is very critical.At present,China's men's javelin athletics level has been stagnant,reserve personnel shortage,therefore,do a good job training of reserve talents,attach importance to the development of physical fitness athlete,a profound understanding of physical characteristics of each age group of athletes is very important.Javelin belonging Stamina Oriented Speedy Strength project,which requires both a javelin thrower superb technical movements,but also have a good physical foundation.15-16-year-olds are sensitive periods of physical development javelin thrower,it has its own unique physical characteristics.If you fully understand the physical structure of this age group athletes,there are clear and complete fitness system concept and objective evaluation criteria in order to provide scientific support for the theory of selection and training for the development of javelin reserve people to contribute.Therefore,javelin throwers physical research in this age group are very valuable.In this study,Zhejiang Elite Male 15-16 23 human subjects,from the shape of the athletes physical,functional,three levels of quality were analyzed to explore.First collected by literature original physical indicators,and then let the experts by questionnaire qualitative analysis of the original screening index,then use the principal component analysis of indicators for a second round of screening to determine the typical indicators of physical systems.Then use the index to determine the method of gray correlation weights,using regression analysis to establish a predictive model scores;in determining weights developed on the basis of a comprehensive physical evaluation criteria.The final conclusions of the study are as follows:1.The physical structure of Zhejiang Province,Zhejiang Province,15-16 years old Male Javelin Throwers mainly from the body shape,function and quality of the three major categories,nine typical indicators to reflect.This 9 each index are:height,Quetelet index finger distance-height,serum testosterone,heart function index,the whole run-up to vote 200g pellets,standing triple jump,throwing his head with both hands before 2 kg shot put 30 meters hold gun run.2.Analysis of gray relation 9 typical indicators of performance are the size of the contribution:the whole run-up to vote 200g pellets>standing triple jump>30 m gunman ran>hands before throwing his head shot 2 kg>Height>Span-height>Quetelet index>serum testosterone>heart function index.Three major categories of right physical structure is small:Physical Fitness>Body shape>bodily functions.15-16 years old Malen performance predicted model3.Zhejiang is:Y = 19.276 + approach full cast two hundred grams pellets × 0.617 +standing triple jump x 0.113.4.This paper has developed indicators for each individual evaluation criteria,then,according to the index weight comprehensive evaluation criteria developed physical structure,provide a reference for the selection and training of coaches.
