提高排球平控开扣球进攻威力的技术研究

Study on the Technique of Attacking Power of Parallel Long Toss Quick Spike

排球平拉开扣球是打乱对方三号位拦网手最有效的战术之一.然而在实战中,技术不易掌握,应有的威力难于发挥。根据平拉开扣球的时空特征,在原有技术的基础上,文中做了一些新的设计,经过实验对比分析,提出采用80度助跑路线,双脚八字型起跳技术,可提高平拉开扣球的进攻威力.

Parallel long toss quick spike in volleyball is one of the most effective tactics to upset the block from the opponentplayer No.3.However,it is not easy for the player to bring the attacking power of this quick spike into full play becauseof the difficulty in mastering the technique.According to the time and space characteristics of the parallel long toss quickspikeand on the basis of the original technique,a new design was made in our study.In the new design,the technique ofrunning approach in 80 degrees and taking off from both feet in the figure of the Chinese numeral 8 was introduced.Through experiment,comparison and analysis,we found that the attacking power of parallel long toss quick spike couldbe improved by using the new design.
