Comprehensive Evaluation Of The Impact Factors Of Athletic Performance Of Elite Female Javelin Athlete

The paper has selected 14 indexes about the athletic abilities, which are based on a long period survey or interview to some our national javelin coaches, also several rounds of experts forum. Meanwhile , I have inspected 3 physical indexes, 4 sports techniques indexes, 7 diathesis indexes,and connected the characteristics of the javelin to get the result. The former two data are resulted by questionnaire survey, and the last one is educed by analyzing the videos that are gathered at the national athletic competition. We selected 8 indexes (physical,technique and diathesis)by factor analysis, ensured 8 sports abilities weight by gray associated analyzing, at the same time, founded the equation of the female athletes'scores and indexes which were selected by equation techniques. We constitute the integrative evaluate standards from physical,technique,diathesis indexes for our national female javelin athletes. The concrete are follows:①Built up our national excellent female javelin athletes'integrative evaluate indexes. The configuration includes height; while quality involve the whole distances help to run to throw 300 grams small ball, sign to settle broad-jump, 30 metres to account, the hands head comes forward to throw shot put; Technique layer index sign for make moves speed, the javelin makes moves the moment left knee Cape, the right foot wears ground body center of gravity level speed. In the tournament the ability structure, 8 positions of index signs BE:release velocity>the whole distances help to run to throw 300 grams small ball>the hands head come forward to throw shot put>sign to settle broad-jump>30 meters start to account>height>the right foot wear ground the level speed of the body center of gravity>the javelin make moves moment left knee Cape.②Built up an our country an excellent woman javelin throw athlete particularly an item the estimate model of result, among them particularly item sensitive index sign model is: Y=-10.488+0.761X₁+5.879X₂,among them小X₁:The whole distances help to run to throw 300 grams small ball,X₂:Sign to settle broad-jump。Our country excellent woman javelin throw athlete particularly item result and contest each related index sign of ability the estimate model of the level for: Y=-10.88-6.451X₁-0.045X₁₄+0.829X₆+0.701X₇+6.561X₁₂-0.018X₈-0.154X₁₀+0.028X₉,Among them X₁:height, X₆:The whole distances help to run to throw 300 grams small ball, X₇:When 30 meters started to account, X₈:release velocity, X₉:The javelin makes moves the moment left knee Cape, X₁₀:The right foot wears the level speed of a ground of body center of gravity, X₁₂:Sign to settle broad-jump, X₁₄:The hands head come forward to throw shot put.③Build up the integrative evaluate standards for physical,technique and diathesis for our country excellent woman javelin throw.In order to contest the ability stage to check and assess to provide a reference to the athlete for the coach member.
