ABSTRACT
In previous studies focusing on the bargaining between two players in one-on-one interpersonal competitions, the relative phase of the velocity shows a certain characteristic. Studies have shown that the phase switches depend on the slight difference in the distance between two players. However, no study has been conducted on the series of movements from the bargaining phase to the settlement of the game. Therefore, this study aimed to quantitatively examine the characteristics of kendo from the bargaining phase to the moment of the strike, focusing on the relative phase of velocity and interpersonal distance. Participants were asked to play a kendo match, with a few restrictions. There were 80 trials, and the experiment ended when one of the participants struck the other. Based on the pattern of change in the relative phase of velocity of the waists, and the interpersonal distance, it was determined that one pattern accounted for 35% of the total trials. The pattern is that at 1–2s before the strike, the two players were in anti-phase, moving in opposite directions with an interpersonal distance of approximately 2.71m between them. Furthermore, at the time of the strike, the two players were in in-phase, moving in the same direction at an interpersonal distance of about 2.38m.
