Abstract
The purpose of this study is to obtain a useful and highly objective index as a basic data for predicting the outcome of a game, and to examine the relationship between the side-out rate and each skill, as well as the relationship between the win and the loss, through a longitudinal game performance analysis of the top level men's and women's collegiate teams. The results obtained are as follows.
1. It is suggested that the evaluation range table created from the side-out rate may serve as a guide for
understanding trends in predicting wins of the set.
2. The correlation coefficients of the skills other than the evaluation of attacks for college men and women were not more than ±0.4, but the superior correlation coefficients were found in the serve point rate and block effectiveness rate for men and serve-receive A+B rate for women.
3. The evaluation range table was made for the evaluation related to attacks, which showed a significant correlation with the side-out rate, indicating that the obtained values are useful in predicting the outcome of a match. These indices will be useful in team-building exercises, such as setting values in game-like practices in the preparation period for games and setting numerical goals in practice games.
