内划比直臂内划力量大的多）。同时注意小臂和手掌朝向向后，不要为了高肘把上臂向

大部分人游蛙泳这样足够好。顶尖的蛙泳选手此时肘离水面仍然相当近（水如粗绿线，

发帖数: 58 | 3 Agree, toss is very important. Another thing worth mentioning is your feet.
For me, my left foot(I am right-handed) is parallel to the baseline before the
serve. Bend your body back, turn your torso, shoulder and swing your racket
smothly. some ppl suggest 打背. It depends, if you toss the ball high, you can
try this.
Yes, practice is very important. Getting consistent serve is key to win match.
Relax when you practice serve, use only 60% of your power. 80% of power is
enough even in matches. Cons |

do you have a kind of "freezing" balance motion while you serve?
It is like when you toss the ball, before you actually turn your torso
(arm,...) drop the racket head, and actually swing,
do you kind of "freeze" your motion like
Knee flexed, looking upward for the ball, and most importantly, with your
wrist stiffen, and racket pointing upward?
And then all the momentum starts from there, and happen really quickly, turn

发帖数: 641 | 5 Part III: Hitting Left or Right or Lacking Power
Problem: Often hitting the ball farther right than intended.
Repairs:
1.You're probably too close to the ball, which cramps your arm(s) into your
body and causes you to pull right as you swing.
2.If your swing is at all rotational, hitting early will make you hit too fa
r right. In a classic one-handed backhand, the upper body rotation early in
the swing should stop when the torso is parallel to the sideline. One-hander
s commonly rotate too much, |

spin and more consistency. i was told years ago at the very beginning that
i should hit with my arm straight, yet i never believed it until i watched

one other thing i corrected after reading tennis magazine was i should not
turn my torso much for single topspin backhand. |

发帖数: 1665 | 10 是这样子的吧？
有几个tips可以帮助肩部转动shoulder turn。反正我的理解就是shoulder turn了
body/torso就turn了。
1. Show your opponent the sign on your back
2. 当你引拍完成时，下巴应该能够碰到或者几乎碰到你的右肩。(击球完成后的随挥，
下巴可以碰到
左肩)。我个人体会这样还有一个好处可以保持头部固定：身体转但是头不转。
如果你引拍的时候就面向球网了，除非你是接一发，不然你没有足够的身体转动，基本
上是胳膊打
球。
不过话又说回来，咱是因为胳膊力量比较小，所以一直讲究整个身体发力。有些哥们儿
天赋很高，一
个胳膊的力量就够了，那就另说了。 |

发帖数: 6788 | 14 wow, put张老三to shame, LOL.
Bend your legs and lower your body a bit more when you take back the racket,
which help "thrust upward", torso rotation, and motion forward. Again see
Clijsters forehand from about 1 minute in this video to see how it's done.
http://www.youtube.com/watch?v=pQZG5_4mxY4
In addition, split step in your preparation when the ball is about to come.

发帖数: 1665 | 18 我的四分钱：
１. 楼主的正手引拍.....感觉好象没有把肌肉拉开。看上去转肩很充分，但是左手和
右手夹着自己的身体torso，所以并没有蓄力的样子。
２. 好象从来没有跳步。比如1:08的反手截击。应该有一个跳步停顿调整重心。不然很
容易被穿越。另外底线rally也没有跳步或者至少下蹲的调整。所以在３缺１的录像里
你脚步看上去很busy。
３. 你在底线用并步shuffle step很多。在长距离跑动中效率不是很高。不过你对手的
球更慢。只是效率问题。Nick的一个录像好象专门讲过。
４. 你发球的握拍好象是东方式的。１:30你打高压用的好象也是东方式握拍。(第一
个高压和第二个高压的调整你也用的是向后的shuffle step。原因是你没有square the
feet。比较高效的应该是侧身，然后交叉步。应该两步就到位了。) |

发帖数: 6757 | 26 correction:
your 2nd stance could be a defensive "open" stance.
Your shoulder turn is fine. Right now is not the time to put too much
emphasis on it.
"wrist snap" is not recommended for you at this stage. If you can't have the
right grip and unable to swing "loosely" (relaxed), you will hurt yourself
trying to snap.
Just focus on prepare early and draw a big C in one smooth stroke. mm's FH
has issues too, such as bear hug w/ her left arm, not using her torso turn
enough etc. |

IMO.
FH, he can use more shoulder turn (faster torso rotation) and less wrist "

to modern FH style where the elbow is not tugged close to the body. This
will generate more speed. Just be careful to watch out for injuries. Kids at

separate lower and upper torso, stretch waist side muscle

- 做在椅子上时， 屁股不动， 肩膀转动， 90度以上。 原理同上。
相对的加快球速： 失误少了才可能加速。。

pitching 时是一根橡皮条扭转 -- 上身和下身扭转度不同。
