The Study On Characteirstics Of Body Shape And Competing Records Of Juvenile Hurdlers In Heilongjiang Province

With the continuous development of the training level of track and field, peoplehave put special emphasis on scientific identification of athletes. Bodily form is thefoundation and key of identification of athletes，and key factors to influence the result.The bodily form and competing records of hurdlers of Juvenile Track and Field inHeilongjiang Province are measured and tested to reveal the characteristics of the bodilyform of hurdlers in Heilongjiang Province, to master the relationship between thecharacteristics of bodily form and their competing records of hurdlers of Juvenile Trackand Field, to provide theoretical support and practice basis for further promotion of theselection, training, faculty construction of the reserved talents of hurdlers of JuvenileTrack and Field in Heilongjiang Province.After measuring8index of bodily form characteriscics and testing the sportcompeting records of the hurdlers of Juvenile Track and Field in Heilongjiang Provincein2008and2009, screening the data obtained, arranging and inputting the raw datawith Excel2003in statistics, accoplishing thesis variance and relevant analysis withSPSS19.0, the result objectively reflect the existing differences in bodily form betweendifferent sex, specialities and age groups of hurdlers of Juvenile Track and Field inHeilongjiang Province. The regression equation of the bodily form and competingrecords between different special athletes is brought by regression method of data.We come to the following conclusions by research and argument:1. Average heightof male adolescent dash players in in Heilongjiang Province has met the requirements ofthe national standard; Average target of female adolescent dash players and lowerextremities B of all the male and female dash players is under the requirements of thenational standard, but no significant differences are observed.2. Quetlet index ofjuvenile male and female hurdlers in Heilongjiang Province and average height of malehurdlers have both met the requirements of the national standard; lower extremities Bindex of110-metre Man Hurdle Race and average height and lower extremities B indexof110-metre Female Hurdle Race are under the requirements of the national standard,but no significant differences are observed.3. Except that the sitting height and lower leg length index of juvenile hurdlers in Heilongjiang Province have no difference, otherindex has significant difference in variables of specific factors.4. Different age groupsof hurdlers of Juvenile Track and Field in Heilongjiang Province has significantdifference in index of height, weight, sitting height, lower extremities B, chest andQuetlet, however, No significant difference has been found in lower leg length index,which shows that with gradual increase in age of juvenile athletes, index of bodily formchanges correspondingly.5. A negative, correlation was significantly found between theheight, weight, and Quetlet index and competing records values of juvenile male100-meter athletes in Heilongjiang Province; sitting height of female100-meter athletes,height of male400-meter athletes and weight of female400-meter athletes, the index ofsports of which enters the Regression Equation, has a predictive function on competingrecords.6. A close relationships of negative correlation can be found between the bodilyform index of lower leg length and lower extremities B and competing records values ofjuvenile male hurdlers in Heilongjiang Province; No obvious relationships have beenfound between bodily form and competing records of female hurdlers; lower extremitiesB index of male hurdlers enter regression equation,which obviously has a predictivefunction on competing records of sports.
