Research On Diagnostic Model Of Chinese First-rate Women's Volleyball Technical And Tactical Skills

In 2004 Athens Olympic Games, the first time that Chinese women's volleyball team won world champion again after 20 years'leave, they won the only one gold medal for collective project groups in China's Olympic delegation. Throughout the Women's Volleyball rugged ups and downs for the past 20 years, from the "five consecutive championships" down to the defeat in Asia in the 1990s, as well as to the Athens Olympic Games'victorious return, the magnificant fruit is attributed to not only the hard training of athlets but also the coaches and research staff's hard work. Besides this was also when the competitive strength of the local volleyball clubs came across the stage of overall development.Local volleyball club's improvement in competitive power is the foundation of overall national strength increase, as is Primarily embodied in: the importation of a large number of outstanding athletes; skills tactics, training management innovation and improvement.As modern science and technology and theory advances gradually into the sports field, the scientific training element has become a key point of victory and the club's long-term survival. In short, scientific training is the only way out for the development of local volleyball clubs and the national volleyball team. Among them, the volleyball tactical skills and scientific diagnosis is a vital part as well as the hardest key point for the whole scientific training system.Through enquiries of the literature we could see that there is little research in this field, especially the the quantitative diagnosis of tactical skills that can be adopted to practice.As training experts point out: accurate diagnosis is the premise to improve the technical and tactical skills, because without it it will be unlikely to control the training process effectively. As Marx once put: "Without the use of mathematics science can not be called what it is." In fact, with mathematics as the platform for "digital" quantitative diagnosis of technical and tactical skills has become the hotspot of training. In order to improve the level of volleyball technical and tactical training, the use of detailed and accurate data to reflect the objective state of technical and tactical skills, and creating accurate digital models of the implementation of scientific training has become an urgent task.Based on previous research results, this study applies the Markov chain of data mining theory to the calculation of indicators of the quantitative theory, with the survey and the qualitative indicators received from expert advice, it has ultimately established the indicators of diagnos of the Chinese women's volleyball skills and tactics . On the basis of Extendable element theory, extendable set theory and the extendable conjugate analysis and evaluation of transitivity yuan of the priorities theories and through collection of statistical indicators of the national volleyball team's technical and tactical skills,we have ultimately established the diagnosis of standard elements models and the classical domine and confinement of diagnosis and also we have constructed China's Class-A Women's Volleyball technical and tactical skills'characteristics of the diagnostic elemental model with the combination of qualitative and quantitative analysis and the subjective and objective factors as well as the dynamics.The study concludes as following: (1)Based on the Excavation theory about index data and the advice of the volleyball experts, a index system is established which contains six technical merit indicators (fast offense,firm offense,block,pass,serve ) as modeling character.(2) Based on the Extendable Engineering, a dynamic quantized diagnosis evaluation model is constructed used the if-then system method. which is about the level of the techniques and tactics for china's women's volleyball. This model provides a factorial terrace to achieve scientific and external evaluation of the techniques and tactics of Women's volleyball and the couches of China .With the test of demonstration, the scientificalness and practicability of this model is certified...
