Preliminary Construction Of The Kinetical Diagnose System To The Long Jump

Long jump is one of the focus in track and field sports,whose advantages and disadvantages effect the score severely.It is proved that the perfect skill in long jump sports can show the bodies' best potential,and gain better result under the same conditions.To achieve greater breakthroughs in the area of long jimp,first,find the gaps and shortage about skill,then analyse and evaluate the long jump action correctly,and explore more scientific and reasonable long-jump skill.In the early 1970s,the United States began to put computer technology into athletes' training.In the later 1980s,the technology of using computer diagnoses exercise has risen to a higher level,and it is widely used to sports training.While it is a world-wide trend that the technology of using computer is used to improve sports training.Integration of the computer technology and sports training is comprehensive,which has infiltrated into many aspects,such as making plan of training,improving training equipment,arranging training load,managing training job,design the new movement, evaluating the results of the training quantitatively as well as predicting the training score.We can find that,if we can design a special,rapid,accurate and simple diagnosis system technology for the long jump,it will have great significance to diagnosing the long jump technique and guiding scientific training.Under the scientific training thought,diagnosing sports technology is that using all kinds of ways evaluates sports technique and effect,based on existing conditions and level of physical training.This process can check the conditions and technical training level of athletes,then propose the means to targeted training and technical improvement measures. With the analysis of the long jump sports as a breakthrough point,the study aims to develop simple,rapid and special diagnostic software systems for the long jump sports.This system can achieve scientific analysis and diagnosis in the area of long jump technique,and it is an active exploration and attempt to our countries' sports science research.Nowadays,sports workers should improve their capability of innovation and research continuously,developing more sport science products containing its own intellectual property rights. This study deploys literature,expert interviews,Delphi Method,systems analysis and computer integrated technology,sports photography and video image analysis method, systems analysis and computer technology,mathematical statistics method and so on.With the background of improving the level of scientific research and the guiding ideology of "to want a gold medal Technology",based on the predecessors' achievement in the area of long jump,the sports technique diagnosis three-dimensional video analysis system as a platform and analysis tools,along with the needs analysis,feasibility study,the overall program design, the framework of structural design,delicate design of the study route,the study intends to construct a database and knowledge base about the informations and parameters of long jump technique.The diagnostic system construct and defines all the stages and aspects' technique indicators of the long jump,define the indicators' technical parameters in the whole moves and different phases.Through referring to great literature and sports images analysis,the study provides domestic and international elite athletes' technical parameters in all the stage and action phase,and set up databases,achieve conventional technology diagnosis;based on domestic and international experts' basic theory and experience model,preparation of operating program,implement mathematical physics model diagnosis and the experience model diagnosis;the system can help coaches visually image analyse and evaluate the sporters' technical action vividly,in doing so we can resolve the long-term problem that coaches can only rely on their own experience and the theory in books to determine if the long jump athletes technology good or bad.In addition,the system,through obtaining the information of the exercise technique,provide valuable reference for athletes to select and train,make the long jump training and competition become scientific,digitization,theoretical, and enhance sports performance.
