发帖数: 9606 | 1 大家就别粉啊黑啊goat啊...来讨论点技术问题吧.
昨天晚上练了一会发球, 通过分解动作发现一些问题. 欢迎大家一起讨论.
3个发球(外角, Body和内角)高清晰录像在这:
http://www.youtube.com/watch?v=wBYH-OAK0E4&hd=1
通过逐祯查看, 剪接出如下三个图片. 每个图片分别记录4个关键时刻:
1. 球到最高点. 身体准备动作完成. 这时候膝盖应该弯曲; 左手抬高; 左手-左肩-右
肩-右大臂应该成一条直线指向天上; 髋骨向外顶出; 身体成弓装.
2. 左手带动肩膀转动, 右肩同时向前甩出, 拍头下垂成捎背状.
3. 击球瞬间. 右手腕Pronation完成. 在这里发现我的老问题: 右手没有完全伸展开来
. 导致击球点过低.
4. 完成动作. 左脚落到场内, 右手随挥完成动作.
大家看看还有什么问题我没注意到的, 欢迎指正. |

发帖数: 9606 | 4 hmm, 我的Pronation的确是不够. 开始是用拍筐去切球, 击球前瞬间
Pronate转成拍面拍球. 估计是因为手腕Pronation不够, 想通过小臂
来辅助导致击球时手臂不能完全伸展开. 下次尝试多用点手腕Pronate |
u**b
发帖数: 398 | 5 Pretty good already. Just my 2 cents and hope it helps...
>>Straight up your right arm. Don't think about pronation, just let it
flow by turning your head down and looking forward as soon as you finished
step 2. Sort of let your head lead the way. It almost looks like you were
pronating the racquet a little too early, and this may cost head speed.
Try finishing the first half of step3 as if you were trying to cut the
ball with the rim. (Hope I make myself clear on this).

发帖数: 1665 | 24 个人意见啊，仅供参考：
首先你的Placement已经很厉害了。基本上想发哪里就发哪里。已经是发球高手了。
意见：
1. 你抛球前握拍太松了。适度松弛是好的。但我觉得是整个身体还有胳膊在开始发力
后要松弛。你现在这样握拍一是不好看(我很追求好看)；二是没有什么实际意义。可以
看出你抛球前手腕是松的；但是开始挥拍后并不太松弛流畅。有hold back的感觉。
2. 你的动力链是broken的。脚和腰的力量没有/或者没有完全传到拍头上。主要就是断
在弯曲的胳膊那里了。
3. 你的发力像是在folding the waist. 看不到侧面，但我猜是抛球的位置偏后。应该
适当在往场内抛一些。另外从你左脚落地的位置也感觉你抛球位置靠后。
4. 转体没有完成。Loading stage的时候，你的转体比较充分。基本上从后面拍摄的位
置都可以看到你的右胸。但击球瞬间和击球后的瞬间，你的身体都是侧对球网的。所以
腰部转动的力量没有完全传到球上。 |

如果你一直都是放松loose的，像甩毛巾一样....或者类似楼上某位大侠说的挥"登山镐
"似的。你的胳
膊应该是自然伸直的吧？
除了放松是关键词外，向上好像也是。

发帖数: 6253 | 50 Your serve is good enough leh.
If any improvement, I think you need to get underneath the ball, like
overhead... Or you have to align your toss...
On frame 3, you hit the ball on the side, which is normally ok for a slice
position...
Toss a little back will help you do the kick, if your wrist is relaxed
enough...
You can try the way Pete used: let your wife call the T/W/B after your toss.

: 大家就别粉啊黑啊goat啊...来讨论点技术问题吧.
: 昨天晚上练了一会发球, 通过分解动作发现一些问题. 欢迎大家一起讨论.
: 3个发球(外角, Body和内角)高清晰录像在这:
: http://www.youtube.com/watch?v=wBYH-OAK0E4&hd=1
: 通过逐祯查看, 剪接出如下三个图片. 每个图片分别记录4个关键时刻:
: 1. 球到最高点. 身体准备动作完成. 这时候膝盖应该弯曲; 左手抬高; 左手-左肩-右
: 肩-右大臂应该成一条直线指向天上; 髋骨向外顶出; 身体成弓装.
: 2. 左手带动肩膀转动, 右肩同时向前甩出, 拍头下垂成捎背状.
: 3. 击球瞬间. 右手腕Pronation完成. 在这里发现我的老问题: 右手没有完全伸展开来
: . 导致击球点过低.

发帖数: 6253 | 53 I think it is very good yah. It served the purpose you want to try:
The pronation did show up. And ball is kicked up.
The thing is still the body motion: you are not hit up or come up to hit...
Your arm is not whipped out enough, maybe too much attention goes to wrist?.
.. From the wrist snap, it is there.
Watch the slow motion for Roger in your fav list. I feel the most different
is he is up to the ball, but you are only snap your wrist and the contact
point is a little low. Your body is not up

发帖数: 6253 | 54 I would like to toss a little right overhead and pull myself in but still
keep this pronation/snap to hit it up and forward...
From my point of view, your arm joint and shoulder is not relaxed enough and
the wrist is relaxed. Or the chain timing is a little weird. Like your arm
and shoulder is pulling back or hold you back, and only the wrist it do its
work.

发帖数: 6253 | 55 You may keep feeling the pronation/snap.
But you may try something else, for example, to toss the ball over your left
shoulder and bent your knee to make your body motion a little forward...
Watching the relation/alignment of Andy's contact point with his body.
Hope this is more clear... |

发帖数: 9606 | 56 I was only practice pronation last night. Did not try much to add
other elements in. The pronation action was wired to me at the
beginning. After several practices, I felt much better. I do not
know if it is because of that court. All the balls kicked up high
after bounce. All of them were one bounce into fence, some of them
even were still rising. Let me feel really well :P This court is
made from hard plastic and there were a lot of small holes in each
square. We had a huge T-storm yesterday. |
