<p>发球的旋转：一是能发出强烈旋转的球；二是能以相同的动作发出不同旋转的球；三是能以不同的动作发出相同旋转的球；其中以第二条最为重要。怎样以相同动作发出不同旋转的球呢？<br/><br/> 1 以球拍不同部位触球。拍头与拍柄部位分别发出转与相对不转球；拍面下侧与拍面上侧部位也分别发出转与不转球。以球拍不同部位触球发出不同旋转的球主要在平时练习时要多加体会，在比赛时要有意识地使用。<br/><br/> 2 以弧形挥拍路线不同时期触球。前期触球为下旋；后期触球为上旋。以弧形挥拍路线不同时期触球发出不同旋转的球要注意掩盖触球瞬间，必要时夸张触球前或触球后的动作。<br/><br/> 3 以手腕不同发力方式触球。手腕发力摩擦则旋转；手腕发力弹击则不转。也有以手腕发力时是否触球发出转与不转。<br/><br/> 4 另外有人以球拍背面的手指发力发出旋转球，不发力则发出相对不转的球；如果真的能发出旋转差别很大的球来的话，那应该算是发球的很高境界了。<br/><br/> 其中以第一点最实用，练习时较容易，发出的球旋转差别大，也比较隐蔽。</p></font></span></span></td></tr></tbody></table> |
