Analyse Volleyball Echelon Construction of Shandong Province
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 Yt ＝ Yt-1+[(Yt-1 —Yt-2)+(Yt-2 — Yt-3)+…+(Yt-n —Yt-(n+l))] ／ 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 1st-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.
