Abstract
The authors attempted to extrapolate the best and worst lines-up for the Japan women's volleyball team in the '00 Olympic Final Qualification games with China. They used the maximum likelihood method and Bradley-Terry Model to retrospectively investigate the nine games between Japan, Cuba, Russia, Brazil, and China in the '99 World Cup Women's Volleyball Games held in Japan (from November 2 to 16, 66 games in total).
Line-up4 was obtained by the best and Line-up6 was the worst. The starting line-up of the Japan team in Line-up4 was R5 with and without the serve. In Line-up6, the starting line-up was R3 with and without the serve, respectively. Line-up6 was the line-up that the Japan team should have avoided. To enhance the team's perfomance, it was necessary to improve the rotation phase with a low offense index and defense index. High defense index was necessary to maintain. Specifically, R4,R5 and R6(low offense index), R1 and R2(low defense index), R3, R5 and R6(high defense index) were applicable to rotation phases for the Japan team in Line-up4. R6(18.5%) and R2(－13) were obtained the most low offense perfomance by point rate and Net Score each method.
