摘　　要：四号位平拉开扣球技术目前已为国内外很多男女排球运动员所应用。而二传球运行时间究竟是多少最为合理?球速慢,对方三号位队员有充裕的时间移动可以组成双人拦网;球速过快则增加扣球难度和配合难度。本文对国内外一些运动员在三号位移动组成双人拦网所需的时间进行统计和采集,并进行必要的数理统计处理,从而从定量上解决上述问题。'Spiking off a wide, low set,' an offensive tactics often operated at the No. 4 position in volleyball play,is now widely used in China and other countries. The speed of the ball in the set-up is most crucial in thiskind of manoeuvre. A slow set-up would allow the No. 3 player of the opposing side to move over for a two-man block, while a fast one would add to the difficulty in mounting the attack.To solve this problem quanti-tatively, statistics have been collected on the different lengths of time taken by Chinese and foreign players inmoving from the No. 3 to the No. 4 position for two-man blocks.
