バレーボールにおける一流センタープレイヤーのブロックのコツに関する研究

抄録

In the present study, we sought to obtain valuable knowledge for athletes, coaches, and staff seeking to enhance sporting performance by demonstrating the blocking tricks of two elite center position volleyball players who won multiple blocking awards in the V. Premier LeagueJapan’s leading volleyball league. Qualitative research helps clarify the inner workings of the subject’s mental state, and is therefore suitable for demonstrating the developmental mechanism and thought process responsible for blocking tricks in volleyball players. Qualitative research is also a suitable solution for bridging the gap between practice and theory that exists in quantitative research because it provides useful knowledge to athletes, coaches, and staff who want to learn more about actual sporting techniques. The thoughts common to the subjects of the present study were their awareness that they were short for their position (center), and that they had learned to solve problems in an appropriate manner. The subjects described the use of “cancel” and “release” blocking tricks as a way of enabling players to participate in blocking combination attacks including quick attacks, and the use of the “split step” as a way of blocking attacks other than quick attacks. The players also refrained from excessive use of the “hands up” blocking position, and when blocking with their hands above the net, they positioned their hands and fingers as close to the net as possible. Both subjects converted the possibility of the setter setting up a spike into clear numerical data in the form of percentages, and applied this information to effectively use their blocking tricks. By describing intrinsic volleyball tricks in words and visualizing them in chronological order with the use of diagrams, our study findings demonstrated the existence and locus of these techniques clearly and made them more teachable.
