| China youth throwing backup talent cultivation model through years of development constantly optimized, select out many good athletes in China. With the development of modern information technology, all kinds of training methods and means of confidentiality decreased, compared with the athletes’personal congenital conditions becomes even more important. Different gender, special for China, and in different age stages of the discus athletes characteristics of the research is not enough in-depth and comprehensive, in the discussion of juvenile discus athletes selecting test indicators, there are insufficient and content on the basis of the research achievements of many just stay on the theoretical guidance, cannot be combined with practice training material is very good as a whole, leading to the selection evaluation, test content cannot be beneficial to improving the yield of the athletes.Early selection of index is numerous, can according to the characteristics of the discus targeted the reflect the characteristics of the special qualities of the selection of sensitive body shape, body function and physical quality index of effective evaluation of the discus athletes, and aimed at different age stages of influential indexes with special performance and focus on practice, can play a twice the result with half the effort, to improve special scores as well as the scientific selection and training provide certain theoretical basis.This research mainly through the literature material method, expert interview method, test method, mathematical statistics method and other methods to reflect the characteristics of the special quality of body shape, body function and physical quality, the following conclusions:1. Our country at the primary stage, selection stage, the key stage of selection of women’s discus athletes in height, weight, sitting height, arms, chest circumference, waist, hip circumference of the seven body shape index level between group and group consensus.2. Our country at the primary stage, selection stage, the key stage of selection of women’s discus athletes in the pulse, the systolic pressure, diastolic blood pressure, and lung capacity on the four evaluation index of body function levels between groups within and between groups.3. Our country at the primary stage, selection stage, the key stage of selection of women’s discus athletes in back strength, vertical jump in succession, crook proneness right hand, left hand grip strength, grip strength,30 meters running result,800 m result, threw the medicine balls, after before the standing triple jump, medicine balls, reaction time on these eleven evaluation index of physical quality in addition to the 800 meters, differences in the group level, but on the difference between groups, in addition to the 800 meters, the rest of the index levels differ between groups.4. All ages young women’s discus special quality income discus special grades to equation regression analysis showed that:12-13 special height and age of triple jump performance contribution rate of the biggest; Throw the ball after the age of 14,15 and ZuoWeiTi proneness to the contribution rate of performance athletes is larger; 16-17, after vertical jump and throw the ball to discus performance contribution is the largest, should pay attention to athletes in every age when select material strength especially rapid strength and explosive force of such material... |
