抄録

The purpose of the present study was to compare the offensive tactics between Beijing Olympic game（BOG）and London Olympic game（LOG）in Japanese women’s volleyball team. Especially, the present study focused on the spending times from the setter releasing the ball to the left side spikers or back spikers hitting the ball. This study analyzed 6 games（21 sets）in the BOG and 8 games（28 sets）in the LOG. The main results were as follows:（1）Because in the LOG spending time decreased in the back row spikes and increase the rate of spike effectiveness, the back row spike was good tactics in the LOG. （2）The effectiveness of left spiker was indirectly related to the increasing the rate of back row spike effectiveness. （3）The back row spikers tried to jump same place in the BOG, but the back spikers changed the place to jump to decrease the spending time in the LOG. When the setter moved to release place, the back row spikers moved the jumping place at the same time to decrease the distance. These findings suggested that to decrease the spending times from setter to spikers were one of the key strategies to success the competitive volleyball games.
