国際男子バレーボール試合の各ローテーション・フェイズによるゲーム分析

―ワールド・スーパー4　'94日本対イタリア―

抄録

    The data obtained at the international male volleyball game Super Four '94 (34 sets in 10 games) were analyzed. The ability to score a total and that to score total side out successes were calculated for our and opponent teams based on the number of serves in team rotation and face-to-face team rotation phases, and then the abilities in each rotation phase was evaluated and compared between teams.

    There were no significant differences in the ability to score a total point and that to score total side out successes in all sets because the coefficient of correlation was r=0.006, whereas significant negative differences were observer with r=-0.380 at a 5% level of significance (p<0.05) when only win sets were evaluated. More, there were also significant negative differences in the ability to score a total point and that to allow an opponent to score a total point with r=-0.380at a 1% leve1 of significance (p<0.01), demonstrating different tendencies between male and female teams.

    The percentage of win sets was 57.1% when the ability to score a total point was evaluated as C (20.8% or more), and 60.9% when the ability to score total side out successes was evaluated as C (47.4% or more). However, the percentage of win sets was markedly decreased to less than 20% when both abilities were evaluated as D.

    We became able to calculate technical results of teams and individual players at each rotation phase by recording technical results of individual players in every rotation phase over the entire game, which were inputted to a personal computer after the end of the game. Preparation of attack and defense formations in our and opponent teams based on the calculated technical results made us to understand the levels of the ability to score a total point and that to score total side out successes in both teams at each rotation phase, and also to characterize our and opponent teams, providing very useful information needed to device a strategy. It was also thought that more effective data could be obtained by adding serves and receives to technical results.
