排球比赛中前后排进攻及跳发球等的运动学对比分析

运用运动学原理及观察、统计等方法,并结合国内外排球大赛的实际,对前后排进攻、跳发球与一般发球等技战术在比赛实战中的效果,进行对比分析。结果显示,后排进攻可以避实击虚,有效地突破对方的严密拦网;跳发球以其力量大、球速快、过网点低、突然性强等优点,比赛中显示出较大的威力,不失为提高发球攻击性的有效手段之一。

Kinematic Comparison on Frontline and Backline Offence and Jump Service in Volleyball Competitions

By the kinematic principle,observation and statistics,and in the light of the real international and national volleyball cometitions, the authors compare and anlize the effect of techniques and tactics such as frontline and backline of fence, jump service and general service in competitions. The result show that the backline offence may get the effect of avoiding the strong side and striking the false side, break efficiently the opponents' tight blocking. The jump service demonstrates its great power,fast ball speed,low overnet point and strong abruptness. Thus,jump service is an efficient means for improving the aggression of service.
