Abstract
We often hear the word "NAGARE" from many volleyball players. Similarly, sports casters often use this word to describe the abstract situation of the game. However, nobody can actually capture "NAGARE" as a visual phenomenon. The present study aims to analyze the structure of "NAGARE" by classifying what players say when they find or feel "NAGARE" in the game. First, words related to "NAGARE" are extracted. Then, the conversational data was analyzed. To analyze the data the Grounded Theory Approach was used, Merton’s Self-fulfilling Prophecy was used as a framework of data analysis. Result revealed that “NAGARE” in volleyball game consists of four concepts; invisible vicious circle, invisible virtuous circle, force of referee, and delay of time. These four concepts are closely related. The core category that incorporates the four concepts was named ‘Subjective fluctuation around the court’. To understand the structure of “NAGARE”, definition of situation is an important element. Whether players can grasp the situation properly will affect the game. It is not easy for players to change the way of defining the situation because definition of situation based on individual player’s experience is ‘preconception’, so to speak. The preconception is difficult to overcome and should be broken down, or changed into a positive way by the director or coach. The findings of the study have a close relationship with the characteristics of volleyball as a sport. Therefore further research for investigating culture and problems related to volleyball is needed.
