Analyse Volleyball Echelon Construction of Shandong Province

摘要

This study analyses a series of problems on the volleyball team echelon construction of Shandong Province, through a great number of discrete data analysis, and put formula of Y_t= Y_(t-1)+[(Y_(t-1) -Y_(t-2))+(Y_(t-2)-Y_(t-3))+.. .+(Y_(t-n)-Y_t-(n+1))] / n into calculation, so as to get the following conclusions: 1. While the number of excellent volleyball teams decreased rapidly, meanwhile, the number of 2nd-line increased steadily year by year, which showed the trend of reverse growth to lst-line; 2. The number of 3rd-line increased slowly, not significantly change, which fluctuated on a certain level; 3. The growing speed of the number of 3rd-line was lower than the number of 2nd-line. This study will play a positive influence and promote the sustainable development of volleyball through the study of analysing volleyball team echelon construction of Shandong Province.
