Study Of Body Shad And Function Evaluation Indicators Of Heilongjiang Province Juevnil Sprinter

The sprint competition increasingly fierce competition, to the training of high levelathletes, need to spend a lot of manpower, material and financial resources, moreimportant is to improve the success rate of selecting sprinters. In this situation, in orderto further improve the sprint level in Heilongjiang Province, close to the faster andnational and world sprint performance, measurement and evaluation at the JuvenileSprinters in Heilongjiang province body shape, physiological function, and theestablishment of Heilongjiang Province, the transport index of body shape andphysiological function of mobilization of material. The formulation of this index will befor the future of sprint athletes in Heilongjiang Province material plays a certainreference value, provides reliable data for the selection and the training work of juvenilesprinters,Through participating in the2010,2011,2012, the Heilongjiang Youth Track andfield championship sprint athletes were7bodily form and3physiological function test,and by using the method of documentation, test method, mathematical statistics analysisto the Heilongjiang Province young sprint athletes body shape and physiologicalfunction of evaluation index statistics and analysis. And carries on the contrast analysisof body shape and physiological function of evaluation index and the state of juveniledash, through the verification of the juvenile sprinter body shape and physiologicalindex of Heilongjiang Province, finally obtains Heilongjiang Province young men andwomen athletes body shape and physiological index.The results are as follows:(1) in Heilongjiang province from12to17year-oldyoung men and women athletes body shape index and national indicators ofcomparative analysis, performance for the height, weight, chest circumference, lowerlimb B, thigh length, length of leg and Achilles tendon and other indicators are higherthan the national standard limit indicators, with significant difference.(2) throughmultivariate analysis on height index of different age of athletes, athletes in the14~17age stages for height growth stage, while the female athletes height faster growth stage of the age is between14~16years old, height index are higher than the national standardlimit index. Men and women of lower extremity B index, from14between~16yearsold is the index of the spurt, and Achilles tendon in the men’s sprinters from the age of14index higher than the Female Sprinters, gap between more and more. Ktole indexwith age data indicate that the Ktole index is growing with collar and growth13~14years rise, between the ages of15~17growth rate is relatively slow, and even has atrend of decline in the age between14~16.(3) through the analysis of the regressionequation, the comprehensive development level of athlete’s body shape, according to thescreening criteria of the test, the mean and the standard calculation of total difference,according to the regression equation, is the basic principle of normal distribution,establish the comprehensive development level of young men and women athletes bodyshape reference evaluation index.(4) the physiological function of Sprinters in heartrate, heart rate and12~17sprinters with age decreased year by year. The change ofblood pressure can be judged whether the adaptation to exercise cardiovascular function.Men and women12~17years old sprinter’s vital capacity was significantly higher thanthat of national vital capacity index.
