随着排球运动的迅速发展,发球技术也日新月异。近年来,出现了许多发球新技术,如远距离发飘球、近距离平砍发球、助跑跳起大力发球等。但目前我国运动员由于身材条件及素质的特点,采用发飘球的较多。大家知道,飘球,是指排球在空气中飞行时不产生自旋,且由于空气对球体作用力方向的经常改变,导致球体在空间有飘荡晃动。由于飘球具有以上特点,所以它在发球技术中占有重要地位,其威力不可低估。
With the rapid development of volleyball, serve technology with each passing day. In recent years, there have been many serve new technologies, such as long-distance floating ball, close-cut flat serve, jumpers jump vigorously serve and so on. However, due to the characteristics of physical condition and quality of athletes in our country, more hairballs are used. As we all know, floating ball, refers to the volleyball flight in the air does not produce spin, and because of the direction of air on the ball force often changes, resulting in the ball floating in space there. Because of floating ball has the above characteristics, so it occupies an important position in the service technology, its power can not be underestimated.
