    This study was designed to analyze the spiking approach of international top level men's players in their games, and to clarify when and how they start their approach and their steps. In this study, two attackers, who were in the match of Brazil versus Italy in 2006 Men's World Championships, were chosen as subjects. The time, distance and speed of each step which they took in that game were analyzed. Based on the attacker's view point, the game situation was divided into three phases- The 1st phase: getting leads to start the approach, The 2nd phase: getting visual information about the setter's movement The 3rd phase: moving to the point which the ball falls. In the 1st phase, attackers moved to starting point of the approach by using side step or two-step and stepped the first approach step called Timing step. In the 2nd phase, attackers stepped the second approach step called Running step and finally hopped. In the 3rd phase, attackers reached takeoff. These results caused by this analysis must be different from the common way of so-called Timing Step and Running Step. This is because the situation which was chosen as subjects were focused on the fast attack.
