想从two strokes per breath变成three strokes per breath,但是弱侧呼吸很不自如
,而且老是呛水。觉得头的位置不够平,也可能手臂的节奏不对。不知道怎么提高。
今天公司游泳池看到一个游的很好的人,动作好轻松,每个stroke都很长,而且腿动得
很慢,提供很少的推力。手臂伸得很靠前,几乎没有水花。此人轻松的游就很快了,手
臂和腿使劲游时极快。
我停下来仔细观察他,细心琢磨然后模仿。还有就是他的flip turn,离池壁很远的时
候就开始了。而我的速度到靠近赤壁转身前就明显降低了。好像由轻微的dolphin kick
助力,不过不能肯定。但是他的腿蹬池壁的位置相当靠下。
非常想练习弱侧呼吸和flip turn。不知有何建议。

来自主题: Swimming版 - 一个小drill
感谢saja最近几周发的链接和他自己的数据(stroke count和速度)。我分析了一下,
加上对TI的粗浅理解,设计了一个小drill。我教的小孩试用两周,效果不错。
A 要解决的问题
25Y到50Y到100Y的scaling还可以,到200Y就不行了。需要练耐力。经过水下观察,
core的耐力比较差。过了100Y,带动腿变慢。
B drill设计
saja其实游的挺好,2分100米,stroke count低。按照他提供的数据和TI的转体驱动理
论,340度转体在半个周期内**平滑**完成,所以这半个周期内几乎要一直保持扭力;
但是由于stroke count低,所以这半个周期时间可不短,比我的小孩正常游的一个周期
还长。综上,saja这种练法对core绝对力量要求不高,对耐力要求不低,是个很好的练
耐力的drill。小孩也小,不宜上力量,以免交叉干扰。所以用TI的发力方式做连续单
向转体,应该对core的耐力锻炼有好处。
但是为了避免TI的glide过长的问题,我让小孩连续转体的时候务必在尽量均匀发力的
情况下适当加快转体速度。
两个方向都练。即顺时针连续转体练习,然后接逆时针... 阅读全帖

iso划频的情况下,速度可以是34秒左右或者30秒左右,说明你单个动作划水路线稳定
,不会因为加力而变形。这很好。
iso速度的情况下,看第二个100米,stroke count是8到13。在你这个速度下,速度应
该随划频的提高几乎线性提高,而实测没有。我觉得有三个可能:1)手臂动作有点不
到位了,划水线路变短了,或者因为划频提高有变形,比如手掌在后半程或许斜着出水
,没有正对后面。2)划/推水力量不够,或者发力不再是均匀加速;如你前面说的,觉
得肱三头肌累,说明在划频提高从而推水时间缩短的情况下,可能这块肌肉的力量有点
达不到。3)整体配合有点问题,打水没跟上,妨碍了转体;或者转体节奏没跟上;这
都会影响划水线路。
第一段,28.9s用13 stroke cycles,34.1s用10 stroke cycles。你游完28.9之后心率
是不是增加了很多?我有此猜测是因为34.1/10与30.6/11的划频差不多,但是速度差距
大;心率上升很多的时候,通常动作的幅度会变小,肌肉收缩会变慢。如果是这样,需

【洒家学爬泳】速度不能scale,转身还是耐力?
对练过转身技术的人来说,转身是会提高还是会降低速度?
大家一般游一个直道50米还是两个25米夹一个转身蹬壁更快?
我现在25米在27秒左右,8-9 stroke cycle/length;50米1:01左右,9-10 stroke
cycle/length;100米常常是2:15左右,10-11 stroke cycle/length(游100米garmin
swim显示的速度四个length还是比较平均的,在32-34秒左右,有时后面的length时间
还短点儿)。在不同的距离中感觉用力程度大致是一样的,都没有all out。
从转身来说,没怎么练过,算是open turn,蹬壁以后会觉得有点缺氧(尽管转身前已
经大吸一口气),缺氧后腿会有点酸。从耐力来说,划频随着长度增加而增加。也不知
道到底是转身还是耐力的原因,速度不能scale。

今天为了报名纽约开水,杀到平时去的游泳池,尽管事先打了电话说没问题,但到了那
儿,lifeguard manager却告诉我他需要请示上级才能time我的1500成绩。原因很简单
,lifeguard的工作是保证大家的安全和游泳池的秩序,不是为大家记成绩。看看满池
子的人,觉得他也很有道理。
不过既然来了,也没理由不下水。反正还没连续游过那么长的距离,就自己测一个吧。
活动了一下关节就下水了,第一次游这么长的距离,怕后来体力不支,游不下来,就省
掉了热身游。
两个星期没下水,今天游泳的感受是:
1、意志力不够,还是不能够长时间地关照、保持各部位的动作要点。到后来只记得要
压胸。别的都只能断断续续地想起来才能做,游一游就忘了。这几天各位在版上提出来
的缺点都犯了,什么catch up,肩髋不同步都犯了。说明还是没有练到如果动作错误就
能靠身体感觉自动发现纠正的地步。
2、体力不够。到后来什么高肘什么打水转体,两次打水(打水是两强两弱,弱的是摆
动,不能叫打水),转体节奏,记得也做不出来了。没有体力支持,技术就是花架子啊。

学习和提高的过程是distance per stroke(dps)从短变长,又从长变短的过程
刚开始学,可能dps是2尺,慢慢变成3尺,4尺,甚至5尺。需要提高速度,又慢慢下降
到4尺甚至更短。
这里说的stroke是单臂。如果更习惯看stroke cycle,前面的数字乘以2。
计算的时候需要扣除蹬壁和水下。

【洒家学爬泳】一个似乎不符合长游的发力方式
上周的讨教中带出来一个问题,TI(或者是我现在自认为的TI)的一个发力方式是这样
的:
1 侧身滑行 - 2 恢复臂入水 - 3 换手(包括恢复臂用力前伸,原引导臂下折,开始划
水)、打水以及转体开始 - 4 转体以及由此带动的划水 - 5 结束划水,划水臂出水,
恢复,侧身滑行一直到这只手臂入水,开始换手。
这个周期中发力集中在3、4阶段,我觉得尤其是第3阶段因为时间短需要爆发力来
initiate整个划水,游长了感觉吃力,容易动作变形。具体的表现就是身体转动角度不
一致,划水路线不一致,划水容易过中线。不知道练习TI的各位是不是在第三阶段也是
这样的爆发式发力?我看Shinji好像没有这个特点。
我个人现在并不是很喜欢这样的发力方式,觉得这样容易导致无氧运动。在长游中应该
是D指导提的匀速转体更优。

自由泳kick相对stroke简单不少,你可以在岸上把breathe+stroke练好,再在池边双手

我刚才开会去了。。。我前面回了,左手不多划,喘两口只是在前一个 stroke
犯错,没吸进啥气的情况下,下一个 stroke 的事后补救,并不是通常的
stroke。。。
我觉得“正确”的游泳教程,里面有一个很重要的假设,就是游泳者基本不犯错,
万一偶尔犯错造成的 short of breath 啥的,自然继续就解决问题了。。。
而 TI 是针对菜鸟游泳者,菜鸟常常犯错的概率比正确的概率要更高有木有!
菜鸟犯错之后,首先的问题不是速度的问题,而是如何不沉的问题。。。
就好比 100 米跨栏,悍将不幸脚勾到栏,直接以拉风的姿势,把栏给勾倒在地,
继续前进。。。但是菜鸟的悲催在于,栏没被勾倒在地,菜鸟自己脸先着地了

Please. Don't get it more complicated that it should be. Are you consistant
on your forehand strokes? Are you running on your toes? Do you have good
form? Are you back on your ready position after each stroke. Those are
fundamental but critical for you to become a solid 4.0 player. The reverse
forehands are only for those shots that are out of position. You can win
without those so called "advanced" shots if you horn your basic ground
strokes.

I do not agree with you majorly in two points.
1) Imagine you'll need to play a USTA match tonight. Right now
you can only hit 10 ground strokes without error. What would you
do? To train ground strokes this afternoon? Or to figure out a
game plan? Or maybe just use the match as a ground stroke training
opportunity? It's fine to pick the last option, but people with
this attitude may not show enough quality in putting up against

理论我不太懂。不过俱乐部主教练应该是非常懂的。咱们版上无论实战和理论恐怕能和
他抗衡的人很少。
我们中级训练课的主要内容就是网前。开始打几组ground stoke作为热身。然后是组合
套路。
先打一拍ground stroke cross court。要求打深。然后立刻接一拍approach shot
down the line。要求动作流畅。人到达网前时球也到了,这时打一拍volley cross
court。要求角度要刁钻。最后是一个overhead。直接把对手干掉。
当然,他的drill有很多种。另外一个更夸张。叫101分。ground stroke造成失误得一
分。ground stoke clean winner得五分。volley clean winner得十分。overhead
clean winner 得十五分。先得101分者胜。重赏之下必有勇夫,大家是勇往直前,有机
会就红着眼睛往网前冲。我又一次被对手连续打了四五个ground stroke error以后,
终于打成了一个overhead winner。当时那个兴奋啊。

底线全lob,网前超牛,就会这两条,双打基本上很厉害了
底线high pace ground stroke,网前一般,这种人基本上没啥戏
一般人的ground stroke,如果不是大斜角,基本上网前好的,照样poach掉
fakepro不是还发球机调8练volley呢吗,那个速度一般人ground stroke根本打不出来

No, that's wrong idea.It's very very efficient for you to improve any
specific tech---no matter baseline or net, topspin, volley, stroke or slice,
when you don't have coach to feed ball to you.
I used 发球机 for SHBH practice 1 hr/ea, 2-3/wk, very very efficient, and
after 6 mon, very quickly changed from pusher slicer to automatically SHBH
stroke more and slice less and less during games.......
if u improve to a higher level, u can adjust machine to swing to both side
corners to practice running s... 阅读全帖

Reducing Errors
Friday, March 22, 2013/byMultiple Authors

As everybody knows, tennis is a game of errors. Deciphering the actual cause
of the error is the initial step in error reduction. A study that I
conducted with nationally ranked juniors in Southern California found that
in match play, there are four main causes of errors:
1. Poor shot selection (46 percent)
2. Below-par movement and spacing (32 percent)
3. I... 阅读全帖

I think fakepros shuaqiu is the topspin shot by player who lack of shoulder
turn and/or body rotation at finish. The stroke and topspin is mostly by arm
.
Use Laosan as example (he's a nice and famous guy ^_^), his stroke start
with racquet down low, drag forward then lift. Shoulder turned a bit at
prep but doesn't turn at finish. This is
Fakepro consider as shuaqiu. I would still say it's topspin shot with some
glitches in the stroke. Also you DON'T need to be a 4.0 to achieve this shot.

Henry lost because his backhand stroke has no offense at all.
Gordan's forehand is also better in control and stroke mechanics.
Henry's forehand topspin is very good through. If he can improve his stroke
mechanics,he will be better.

First of all, we never played, so can't say who's better.
Second, I don't think Lendl is a better than Murray, yet he's coaching
Murray
Lastly, I really like your observations and directness, although I don't
completely agree with the solutions all the time.
This is what I get from your statement "If you could just pivot a little bit
quicker after your stroke..." ==> I get set too late and am not balanced
after the strokes. I totally agree. However "pivot a little bit quicker" is
