バレーボール・ワールドカップ'85大会におけるペルー女子チームの技術分析 : サーブレシーブ返球率について

The World Cup Volleyball Tournament was held in Japan in 1985. The author participated in the tournament as a delegate of Japan and took care of the Peru team. This statistical analysis was performed in order to benefit the future efforts of the team. Serve-reception was divided into 4 (A・B・C・M) ranks according to the position of the return-ball i. e. A=good return B=normal return C=poor return M=miss return The results were as follows. First, the Peru results are compared with those of other teams (JPN・CHN・CUB・URS・BRA・KOR・TUN) in RSR (=rate of serve-reception). 1. A rank RSR was high and C rank RSR was low in the winning-games of the PERU team. 2. A rank RSR was low and M rank RSR was high in the losing-games of the PERU team. 3. There was a statistical significance between PERU and TUN team in A rank RSR. The RSR of the PERU team was better than that of the TUN team. 4. There was a statistical significance between the PERU and the KOR team in M rank of RSR. RSR in PERU team was better than that of the KOR team. Second. RSR of the PERU team members was compared. 1. There was a statistical significance between No. 9 player and No. 5/No. 9 and No. 11/No. 9 and No. 12 players in total counts of serve-reception. There was also significance between No. 6 and No. 5/No. 6 and No. 11/No. 6 and No. 12 players. 2. There was a statistical significance between No. 9 and No. 11/No. 9 and No. 5 in M rank of RSR. 3. It was concluded that in the PERU team it is important for a high performance player such as No. 9 to participate actively in serve-reception.
