Thirteen points were digitized on each frame and included the six player's both feet and ball at 0.1-minute interval. The two-dimensional coordinates of the player's both feet on a TV monitor were converted to real coordinates by Direct Linear Transformation Method. The player's position was mean of both feet and the moved distance and velocity curves of the players obtained. 1. The moment of the setter's hand touch the ball, PERU, CHINA, U.S.A., JAPAN assumed defensive position of 3-2-1, U.S.S.R. assumed defenseve position of 3-1-2. 2.
