Preliminary Establishment Of China's Outstanding Men's High Jump Technique Kinematics Diagnosis System

Once the high jump was the advantages of our projects,the 20th century,70s and 80s are the peak of development in the high jump,the elite high jump athletes in track and field history had glorious pages.Ni zhi qin broke the men's world record-2.28meter,and later Zhu jian hua had three times to break the world record,up to now,the 2.39meter is still the Asia and the national record.However,with the old group of athletes retired,China's high jump gradually dimmed in the world arena.At the same time the high jump level also had a certain degree of decline.How to make the high jump event out of the bottom to catch up with the world level,and how to make the high jump to the scientific training,have been the questions to consider for the scientific researcher and coaches.Looking up the books and periodical net of the high jump,the author finded that the most researches of the high jump were kinematics analysis of the tache technique from the whole,and considering every tache as a sport system to study was the comparatively small, but different technical tache was a relatively close contact.So it is necessary to consider the technical movements of athletes from the whole,exercise score as the dependent variable,the kinematics technique indicators of every tache as variables,put computer technology applied to technical analysis and sports training,and set up a technical diagnostic system.China outstanding men's high jump technique diagnostic system based on high jump technique kinematics database,and majority biological data and kinetic data acquisition equipment belonged to contact measurement.Because of elite athlete's non-contact and game restrictions,the system is set up mainly from the kinematics point,uses systemic and developmental principles,bases on system indicators comprehensive and practicality,strives to achieve the purpose of the rapid,accurate and stable feedback.The best men's high jump technique diagnostic system is set up through the Visual C+ +6.0 software programming, which can not only provides concise quantitative indicators for coach,but also clearly sees athlete's advantages and disadvantage indicators,and recommends the express feedback training in intelligent decision-making to make coach enable the timely detection of problems that exist in and arranges targeted training programs.Athletes can see a clear image,directly form a self-contrast cognition with the elite athletes,for their own technology to lay a foundation to improve.The thesis resorted to literature consultation,preliminary understand the status quo and trend of high jump technique,based on the important results of theoretical research,and drafted the indicators appearing in 71 literatures for the original targets.It made use of Delphi Method to initially choose the original indicators,remained 51 indicators after three rounds of questionnaires,determined through three-dimensional measurement machine camera filming elite male high jumper technology from two perspectives,and adopted the Ariel image analysis software to analyze images.Then it used cluster analysis and factor analysis to process 51 indicators of analytical data with statistical analysis,and finally formed 18 evaluation indicators;And used of the system design process to evaluate technology-based diagnostic systems which set up in the high jump,and finally reached the following conclusions:1.China's outstanding men's high jump was a technical evaluation system,comprising of evaluation index system,index weights and the evaluation criteria.Evaluation index system mainly had the three levels of compositions,the run-up stage,the take-off stage and the cross-rod stage of the speed,posture and rhythm category,which of taxis was:take-off stage> the run-up stage>the cross-rod stage.According to expert survey and factor analysis,it was that weights of indicators,evaluation criteria,included individual indicators for the evaluation criteria and general indicators standards.2.High jump technique diagnostic system was a closed-loop control system,and mainly had the high jump technique kinematics evaluation system,integrated decision-making, diagnostic feedback.3.The basic information and testing data of athletes were enter into high jump technology diagnostic system software to achieve analysis and diagnosis of high technique, which mainly included basic information,data entry,data comparative analysis,data evaluation,data output,data query and intelligent decision-making.
