The Comprehensive Index Evaluation System And Design Of Javelin Junior Players

This article mainly expound the current situation of the sport called Javelin, especially tells us the reason why Javelin progressed difficultly. It illustrates the rationality and importance of scientific selecting material and describes this scheme in detail and finally commits it to reality.Javelin had a long history and it was listed as one of the 5 athletic items on the 18th ancient Olympic Games in 708BC.. The Javelin in our country used to break the record in Asia, but it has lost the superior status now. Worse still, it fell behind the other countries and its distance was much far from the world advanced level. Therefore, training the Javelin reserved talents becomes the most important.The foundation of training the outstanding talents is to work out the scientific selecting material. As we know, the traditional scientific selecting material is lack of science. It not only leads to the lost of labor and resource of our nation, but also results in the case that we can't pick out the excellent Javelin athletes, furthermore, it restricts the development of the Javelin. Hence, we should change the traditional concept of selecting material and make a scientific selecting material. Firstly, it can shorten the training period. Secondly, it can save our national resources. Finally, it can break through the development of our national Javelin.Whether the Javelin athletes can acquire splendid performance or not depends on many factors, such as physical attribute, strength harmony and flexibility, psychological attribute and so on. While selecting the material, it is necessary to comprehensively evaluate in order to gain a reasonable consequence. This article consists of 7 indices of first grade and then subdivides 24 indices of second grade, it elaborates the importance and testing methods and devises each subordinate function of the blurry process of the 24 indices, finally, utilizing their subordinate degree to comprehensively evaluate and select the material.At last, the author tightly follows the development of IT Technology and realizes the selecting material system of the Javelin athletes on the platform of SQL Serve and Delphi according to the thinking of scientific selecting material of this article. This system reduces the working quantity a lot for the Javelin athletes and simplifies the procedure. The selecting material staff only inputs every athlete's testing result, the computer can automatically figure out the consequence of each athlete's obscurely comprehensive evaluation and put all the performances in order.Though the thought of this article hasn't been applied to the selecting material of Javelin at present, obscurely comprehensive evaluation had been favorable used in the evaluation of many other athletes. Therefore, we believe that it's an inevitable tendency for this thought of scientifically reasonable comprehensive evaluation, which is applied to every athlete's selecting material. The application of physical selecting material in computer technique will further enlarge and it is beneficial for the coaches, the athletes, even the selecting material workers.
