[技術] Kick serve?
在TW的討論文章裡面 看到了一段:
For the kicker the movement is like throwing a hammer (with a continental grip)
and lead with the edge of your racket, opening it up at the very last second;
for more kick, toss the ball slightly behind your head, hit up and across the
ball from left to right, with the back of your hand toward your ear
pronating your arm and snapping your wrist outward (not downward),
finishing across the body.
上旋發球的Swing phase,怎麼練都是手腕由
Hyperextension/Suppination --> wrist flexion (就是指Downward)
但是要發出有前衝力又跳得高的上旋,勢必要用到Pronation
但是最後隨揮的動作不是downward,是ourtward,這是怎麼辦到的
(就是ulnar deviation)
(研究很多youtube影片可以看到一些高手或選手收拍的拍面是掌心向前外,而非向後向下)
上旋的動力是向上打,靠你pronation時,朝outward向上向前的加速度產生的
不過這要怎麼擊球呢?感覺施力不順(平擊球的pronation就順很多@@)
向上刷但掌心最後又要向外???
