发帖数: 6757 | 1 你们讲的这两点都很重要。我可能说的太general了，我认为你们说的这两点都该是自
己对照时的两个mile stone, 我所说的放松包括了这两项。 放松了拍头自然会drop,
手抓得紧紧的刻意把拍头drop达不到你想要的效果， wrist snap也一样， 我从来不想
这个，但只要放松，一旦拍头起动，wrist snap 也是自然的。
我觉得网上很多教材太注重effect的，容易把wsn误导。但如果只说cause, 可能会让人
觉得过于简单，wsn可能觉得这种简单的道理不是真正自己做不到的原因。道理简单，
但真正能做到难。这些effect也该知道，但只是拿来做检测。 |

发帖数: 3845 | 2 不同的网站教法不一样，黄毛球崇尚pronation，但是十分刻意的pronation反而减缓拍
头速度。有些教练崇尚writ snap，但是容易让人误解成主要靠wrist。其实击球一瞬间
的动作既包含pronation也包含wrist snap。只要smooth就可以。但是千万不要arming
the ball，这是elbow和shoulder受伤的主要原因。 |

icing is most important.
then use cold/heat cream to rub it.
raise your hand/arm to increase to blood flow.
when coming back from injury, use a 1,2 pound dumbbell to do some wrist
exercise. If it still hurts when doing dumbbell exercise, stop doing the
exercise, and definite don't play tennis.
if getting back to play, use sports tape or wrist band. |

发帖数: 615 | 6 Impressive! Wish my son can be anywhere near that.
IMO.
FH, he can use more shoulder turn (faster torso rotation) and less wrist "
turn/flip/snap/jerk", not sure the right wold. He is definitely more toward
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
this age are trying hard to impress. Don't over use wrist. |

you need to make sure there is

2. Racquet head drop below wrist, below ball
3. Solid contact

发帖数: 1696 | 17 我也是自己琢磨的，因为正在教我的小孩发球。你让专业的教练看看可能会更有帮助。
发球动作因人而异，职业球员间也有很大区别，都是为了把动力链连起来，最后那一下
的爆发。
你说的对，但是好像不是最直接的原因。他的动作一直到挠背作的都很好，从腿到头，
包括左手都很好，很职业，但是最终那一下感觉没有爆发起来。你说“打出去的球声音
不脆，听着就没力”，大概是削的太多感觉。可能就是最后那一下的wrist snap的
timing问题。前面的所有load的力量，大多是在那里最终执行。因为他结束动作表明他
的确是作了wrist snap，所以我觉得是timing而不是动作本身问题。

发帖数: 1696 | 18 your son's grip and hitting is a bit unique. Normally eastern or semi-
western grip naturally goes up the left shoulder at this age because they
hit low to high and the swing path is mostly due to the arm movement, not
wrist. Most kids I see are like that.
With stronger and stronger body and wrist, eventually the swing will evolve
to the modern way of finishing for semiwestern, i.e. ending at the left.
He started from extreme-western, that way it's awkward to finish up the
shoulder.

发帖数: 6757 | 22 "Whether racquet head passing plane or not should not be a main factor."
You are right, I did the point out the key point is at the contact. At the
contact it's about the flick/brush through the ball with fast racquet head
speed. However, try to set the racquet pass your body plane and swing
directly toward the ball, and flick it, it is very very difficult. Thus I
use it as a key point to check for ATP/WTA FH.
I agree one of the racquet head speed at the contact is a key point. But I

发帖数: 3845 | 23 In that case, I'm also using ATP forehand.
It's because xbd thinks a better way is racquet tip pointing forward (
backswing like murray does), delaying wrist layback until the last moment (
delaying getting into the slot). Then somebody pointed out it's the main
difference between WTA and ATP forehand. I think for WSN, getting into the
slot early (layback wrist early) is a shortcut to learn an above-average
forehand

发帖数: 3845 | 26 最近思考了一下，WTA FH为什么引拍那么大？因为发力机制不一样，WTA Forehand更多
swing forward, hit through, 很少 wrist 或windshield wiper, 所以需要大引拍，
行程长，把拍速升上去。 用windshield wiper 正手的球友也许有体会，从slot 往前
挥的速度很慢很放松，等到contact point 前一瞬间，那时wrist还是lay back,
racquet head drop, 这时才突然爆发开始 wiper motion, 所以这种正手不需要很大的
backswing。

发帖数: 3845 | 27 我觉得所谓的pronation是手臂放松wrist snap的结果，但如果老想着pronation反而手

也就是朝着头顶上盯着球拍过去。另外，loose grip pressure, loose arm也很关键。 |

发帖数: 6757 | 29 又回到 pronation 定义的话题上了。。。
先说你的问题吧， 发球这玩意只能靠多练， 控制方面主要是抛球和引拍， 真正
initiate upward swing后, 基本就是靠种感觉了，因为你必须得保持放松， 越想控制
越容易僵，越发不好球。 抛球后协调不好，对初学者都很正常， 你抛球是否每次都能
抛到一个点，一个高度， 引拍和抛球是否每次都能协调的对上？
回到pronation的话题上。 我认为pronation有两种， 发球需要racquet on edge, 到
最后一刹那，"wrist snap" 是一种 pronation, 这是正常发球必要的（righty
serving a lefty serve maybe different). 第二种是一般youtube上或网上常说的
pronation, 就是在这"wrist snap" 自然 pronation后， 继续pronate 下去， 拍子继
续向外，手肘向内转，到高于手。 第二种的确可以让你的发球更平更快，但很容易受
伤（golf elbow). 所以我对业余学发球的人都是极其反对的。 其实pro 比赛中这种发... 阅读全帖 |

发帖数: 6757 | 33 视频里的也算是上旋的一种，但与我和bee说的还是有些不同。视频里拍面在slot时 比
较偏side fence, 所以他打的球猛也会有些上旋。 因为要pace 所以需要lock wrist，
他的ww是wiper 带些rolls. 我和小蜜蜂说的那种正手更重，但pace不入视频里的；ww
是flick/snap 完成的。
两种都可行，我个人看法视频的那种更适合身材高大健壮，我和小蜜蜂的这种比较适合
grinder 体力好的。 我的经验是第一种只要我能跑到位就不难接，即使slice chip
chop都不会太难。我们的这种，慢些但更难timing, 差一点就会让人接得难受，特别是
反手。 你可以看为第一种靠pace 打出你的strike zone 左边或右边，上旋只是给球一
定的margin. 第二种完全是用上旋做为weapon, 让球跳出你的strike zone 的上方。第

有个底座拧在相机底部，另一头接相机右侧的带孔，neck strap 可以接在 wrist
strap 上。贴手背是圆角三角形的皮垫。还算舒适吧，如果安装得法的话。
用了有一个月了吧，带着这个腕带拍了将近一千张，觉得长时间手持拍摄时相当管
用。明显分担手指受力，握机更稳，抓拍更快速，换镜头也方便，而且不用担心摔
机子（对，挂着 neck strap 一样会摔机子）。竖拍或者装备比较重时效果尤其明
显。
缺点么，安装不当时有个地方会卡手，用三角架多时只帮倒忙（这个腕带的底座带
三角架孔，稳定性未知），D80 上底座挡电池仓，不过这倒不算个问题。装手柄后
再装这个，会不会影响竖拍的手感（多出个底座来）就不知道了 -- 我是把它当作
手柄替代品的。
