The Research Of Relations Between The Specific Strength Of Flop High-jumper And Performance

The high jump as a competitive sport has been one hundred years , at the beginning, many people believe that success depends on the rationality of the clearing the bar. So people put way to create high jump movement ways as the main means to develop by which the first leap orthodx straddle to the scissors jump, and later appeared in western roll and straddle jump method, until now the most scientific of the flop.After the 20th century 50s, people focus on strength development and training, manifested in the run-up speed has been accelerated, to increase swing speed and magnitude of the objective is to increase the high jump take-off power. In this case, the strength of athletes, especially the specific strength is more demanding. Increase in specific strength to prevent injuries, faster and better mastery of the skills, a great impetus to the movement is also the basis for the high jump. To win the high jump. movement of the specific strength must conduct a comprehensive study and analysis, in order to find out more methods and means of the scientific specific strength training and inspectionIn the research, the Xi'an Institute of Physical Education of Physical Education 2007 and 2008 to reach and close to two levels of student athletes, as the research object, using the literature material law, the expert interview law, the mathematical analytic method carries on the analysis and the research to athlete's special strength's target, has established the more scientific special strength indicator system and the high-jumper special result prediction model for the high-jumper, provides the reference for high-jumper's science training. Main findings as follow:Firstly,obtained the results through the measurement and systematic study of 15 students in the high jump, thirty meters running, standing stye long jump, six-step run-up and five-step stride jump, four-step jump and reach by run-up, squat and shot put after throwing.Secondly,there are six special indicators of the excellent players of high jump which got through expert interviews and questionnaire surveys, the study found that the high jump performance by the impact on the results of it as follows: jump and reach by run-up, six-step run-up and five-step stride jump, thirty meters running, standing long jump, shot put after throwing, and squat.Thirdly,the date has carried on the relevant analysis, linear regression analysis, the multivariate linear regression analysis using statistics principle to the individual movement project to the high jump result's influence, the stepwise regression analysis, has made the good progress, and has carried on the theory explanation to the result. Lastly,based on the above studies, the research has established the model for high jump, found the factors which have impacts on the hing jump and made the optimized of the training.
