二跳加速发球技巧图解

在网球场上，加速发球是一种常见的技术，它不仅能够提高发球的威力，还能让对方感到压力，二跳加速发球通常用于中段到后段，其动作流畅、有力，能够在比赛中起到关键作用，本文将详细介绍二跳加速发球的技术要点和图解，帮助你在实战中更好地掌握这项技能。

技术要点

1、准备阶段：

身体位置：保持身体直立，头部向前倾斜，以适应拍头的旋转。

手臂位置：将右手手腕放在肩部下方，掌心向上，手指稍微弯曲，与肩膀成45度角。

握拍方式：使用大姆指和食指进行握拍，保持稳定。

2、挥拍动作：

拍头旋转：拍头先向一侧旋转，然后迅速回到原位，形成一个80度的弧线。

击球瞬间：在拍头旋转的同时，快速按下左脚，同时用右脚蹬地，产生弹力，推动球飞行。

3、释放时机：

- 发球时，应提前发出，避免用力过猛导致球偏出界或反弹不稳。

4、控制速度：

- 根据对手的速度和场地情况，适当调整发球速度，避免过快或过慢。

5、协调性：

- 进行二跳加速发球时，需要协调左右脚的动作，确保整体动作流畅。

6、力量训练：

- 增强腿部力量，特别是大腿前侧肌肉，可以显著提升二跳加速发球的能力。
