The subject. matches were a total of 27 matches including eight international female volleyball matches and 19 domestic matches during a period from 2011 to 2013. We devised a 2-LS alternative method in which one type of line-up stream is selected from two types of line-up stream to determine the starting line-up. It is the method that players of opponent team who are kept eyes on are determined and our setters don’t make five plays at the front. There were a marked group with whom we play less than five plays and other group with five plays. In addition, a starting line- up which was applied for actual match was made actual group. As for the ranking of starting line-up at each set, the ranking of set acquisition rate was applied and the ranking per set in 27 matches was calculated. As for the ranking per set, the ranking per set in marked group was higher in actual group and winner team of marked group, defeat team, or whole groups and a significant different was found with 0.1% level. From these results, we considered that the starting line-up by 2-LS alternative method is applicable. As for the ranking per set in marked group and other group, no significant difference was found between winner team and whole groups. However, a significant difference was found with defeat team at 5% level. From this finding, we considered that the starting line-up corresponding to the situation that the setter deals with opponent marked players five times should be avoided. In a selected starting line-up, we applied team-plus rate to improve the team power.
