通过练习,大多数人均可拥有稳健的第二发球——旋转发球。它不是一种仅仅进入发球区内的软弱发球,也不会引起太多的双误。发第二发球时必须充满信心。如果缺乏信心,你就变得紧张,紧张的肌肉使你拍头速度无法发挥出来。旋转发球其实比大力平击发球需要更多的指头速度才能产生旋转。旋转越多越好控制。 为了提高第二发球的信心,你必须在计分练习中保持连续发出10个成功的旋转球,周而复始。当你连续发出八九个球时,你会感到有点压力,这是完全正常 Through practice, most people can have a steady second serve - spin serve. It is not a mere serve into the teeing ground, it does not cause too many double errors. The second serve must be full of confidence. If lack of confidence, you become nervous, nervous muscles make your head speed can not play out. Spinning serve actually requires more finger speed than a flat serve to produce rotation. The more rotation the better control. In order to improve the confidence of the second serve, you must maintain a continuous succession of 10 successful spinning spheres in your scoring practice. When you make 89 consecutive balls, you feel a bit pressured, which is perfectly normal
