教练排球通常用二根橡筋,将球悬挂在树与树或柱与柱等物之间,使用时有一很大弱点,即每次扣球后,球来回晃动,不易固定,必须专人用手或竹杆等物将球稳定,才能进行第二次扣球。对初学者来说,既费时又费力,很不方便。现介绍三种改进方法,供教学与训练中参考。一、穿绳法在球的两侧“耳扣”上各穿甲、乙两细绳,甲绳长5米左右,乙绳长3米左右;绳头一端成“Y”形或“V”形(见图1_(1-2))。使用时,在球的后下方45度角左右,距离4～5米处钉一木桩或铁桩A(桩
Coach volleyball usually uses two elastics. The ball is suspended between trees and trees or columns and columns. When used, there is a big weakness. After each spiking, the ball oscillates back and forth and is not easy to fix. It must be handed by hand. Or bamboo sticks and other things to stabilize the ball in order to carry out the second spiking. For beginners, it is time consuming, laborious and inconvenient. Three improved methods are introduced for reference in teaching and training. First, wear the rope method in the ball on both sides of the “ear buckle” on each piercing, B two fine ropes, a rope length of 5 meters, B rope length of 3 meters; one end of the rope into a “Y” or “V” Shape (see Figure 1_(1-2)). When used, nail a wooden stake or iron stake A (pile) around the bottom 45 degrees of the ball and 4 to 5 meters away from the ball.
