发帖数: 14 | 4 说实话，我觉得这块金牌还该是他的//别打我
我自己很擅长游泳，自信地说比较内行吧。PIERCO有争议的那个转身动作，我仔细看了回
放，说实话我觉得没什么很严重违规的地方，而且整个动作很流畅，应该说属于转身的正
常范围，没有明显的自由泳动作。他其实就是转身稍早了那么一个STROKE的样子，当时手
臂仍然正常伸平等待触壁，腿做了一下自由泳的打腿，也就一个STROKE吧。仰泳规则里是
允许转身的时候打腿的(这和蛙泳规则不一样)。PIERCO唯一有点争议的地方在我看来是他
转身略早了一点，理论上转身时马上就应触壁，而他打腿了有一两个STROKE的样子。但是
这应该可以算正常误差之内，况且在仰泳的规则里，他这样做也没捞到好处，并没有占优
势，本来仰泳转身就是可以打腿的，早打晚打区别不大。另外PIERCO领先那么多，实力是
显而易见高出一截的，真要为了这个可判可不判的“犯规”取消人家金牌，才是不公平的
。看银牌获得者没争什么俱知道大家心里明白输得服气。
不过话说回来，这个裁判说犯规，按比赛规则说那就犯规了。美国投诉的争议也应该去力
争这个犯规不该判上，但是偏偏这个犯规就属于裤裆里抹黄泥那种，说不清 |

发帖数: 3419 | 6 你这个也不能把S2000捧到天上啊，2L的NA发动机潜力也就那样了，竞争力肯定不如大
排量或者增压机啦。要说过往的NA机，E46 M3的I6其实更牛一些，虽然8000rpm的转速
比S2000低了1k，但你得考虑到S2K的发动机是oversquare的，stroke短（bore x
stroke 87 x 84 mm），这种很容易做到高转，相反E46 M3 bore x stroke 87 x 91 mm
。所以S2K的缺陷就是扭矩弱，解决办法就是保持高转低档位。所以比最高转速意义不
太大，我还说M3 I6的活塞运行速度比S2K大呢。另外小排量的引擎更容易做到高转，不
信你去看看摩托车的rpm。跟458比就更没意义了。 |

1. Head CT is sensitive to detect intracranial hemorrhagic stroke, but show
nothing for ischemia for the first 24-48 hours, so if the symptoms continue,
do MRI for sure. Without symptomatic evidence, MRI is optional.
2. For lunar stroke or TIA, prevention is all you can do.
3. Given the ischemic stroke occurs, thrombolytic may help, but therapeutic
window is only the first 3 hours from onset. |

还有轻的要在前面,重的要在后面,尽量使船头向上翘
有人知道应该如何开始进行训练呢?
我觉得一开始就直接上船划水是急功近利的做法,会让浆手更难掌握正确的节奏,姿势,
和STROKE.培养节奏感,训练体能,爆发力,耐力,是先期的重点.刚开始先期训练更多,船
上训练占少数.之后穿上训练越来越多.训练集体节奏感可以把板凳排成两排,每人各拿
一只桨,直接划在地上,在地上画线,应该在什么地方下桨,什么点起桨,用节拍器打拍子,
按照节拍练.
我之前在网上RESEARCH的时候看到说划龙舟每一次STROKE桨不能超过自己的身体,必须
在桨到和自己身体平行的地方就起桨.桨要立着,紧贴船身.其中还有提到要ROTATE桨的
角度这样对肩的STRESS更少,但对划龙舟,STROKE/MINUTE才是王道(当然是在齐的前提下
),其他的技巧能起的作用都是很MINIMAL的.
我也不知道我以上有多少说得对有多少没对,谁比较懂? |

it was kind of mediocre round without those two lucky putts. In stroke play,

Bruce Sizemore 和super stroke 在2011年底开始合作生产了DCF系列的putter。
外观非常亮骚，尤其是配上了亮银色的super stroke的grip之后，简直亮得不能再亮了。
也许太亮骚了，所以受到了广大质朴的美国人民的唾弃，并没有取得很大的成功，
原价350的杆子现在在ebay只要75就能买到。
2012年底，super stroke宣布彻底退出putter市场，只生产grip。可惜啊。

It is possible that each stroke takes more than one second. You should
practice freestyle swimming with the
slowest possible strokes. If you can't slow down your strokes, it means that
you haven't mastered the
technique yet. |

think it's part of the reason that I injured my left knee in the Ironman AZ

Also, wetsuits are designed for freestyle and not very b-stroke friendly.
Third, you'll be HATED by other triathletes if you do b-stroke!!
Even if your swimming is in better shape comapred to bike and run, I think
you should still practice freestyle. You have enough time, and it will

降回来了，腰伤基本不太影响跑步了，下周恢复正常训练.
游泳这两周也有懈怠，每周只游了2次，不过这周貌似突然找到点感觉，效率提高
了不少，500yd最快游到8:35了，平均Stro... 阅读全帖 |

发帖数: 281 | 42 Use your hand to lengthen your bodyline before using it to stroke.
就象伸出手去够高处的东西一样. 当手臂进入水时, 要先尽量先向前伸,
而不是先急着向下划.
Don't rush to process. Leave your hand extended before starting
to pull back. Don't be in a hurry to start stroking. Chant silently,
if it helps: "Enter, e-x-t-e-n-d, pause and pull." Just let your
hand keep gliding forward out there, reaching as long as possible
before you begin stroke. |

发帖数: 16204 | 43 For 25 yards, when I do the minimizing SPL (stroke per lap) drills, I can
get it done with 11-12 strokes.
During cruising (longer than 400 yards), I think I need around 16 strokes
per 25 yard. |

发帖数: 18 | 44 My personal opinion is that no matter what your stroke looks like, the most
thing that you should care about is the efficiency. In other words, how far
you can move your body forward by each stroke. Effortless is just another
way to describe your stroke's efficiency and effectiveness.
For long distance swimming, it is similar to running in the sense that at
some point, you will reach the limit. But once you pass that limit, you are
through, and you will feel much better.
I love swimming b/c |

发帖数: 359 | 45 螺旋式，helical stroke 或 spin stroke. (I have avoided screwy stroke.) 身体
往顺时针或逆时针方向旋转，自由泳打
腿，自由泳和仰泳划水交替进行，仰泳换气。以前听别人说过，今天自己试了试，想了
想，感觉还是有一定道理的，只是
初学者容易头晕，撞墙，习惯后速度还是挺块的，而且呼吸象仰泳一样轻松而充分。大
家可以讨论讨论。 |

发帖数: 559 | 47 Great swim as usual. Here is how I rank her from best to worst of her four
strokes: butterfly, back, free and breast. It would help if you have the
fractions/time of each stroke so you can keep track of her improvement on
each stroke. I believe her swimming is fine but the difference is in
strength/pull.
Let us work on her breaststroke since she would gain the most. Please pay
attention to width of her knees on her "whip kicks". It maybe a bit too
wide and caused drag. In addition, the timin |

发帖数: 9616 | 48 1st kick is for high hip
2nd kick is for helping breath.
My understanding is it depend on your breath pattern:
#1. Breath for every stroke:both kicks should be strong. ie, phelps
#2. Breath for every 2 strokes: 1st strong 2nd weak and flat to maintain
streamline. ie, most of the swimmer
#3. Breath 2 for every 3 strokes: in between #1 and #2. ie, misty in
200m. |

发帖数: 139 | 49 Personally, I think butterfly is the most strenuous stroke. Butterfly
requires tremedous energy from swimmers. I was wondering how can
recreational swimmers like us swim a quality butterfly over a long distance
like 100 m or 200 m. I saw lots of people's butterfly becomes survival or
struggling butterfly during the last 25 of 100m. Any suggestion for getting
stamina in butterfly.
Also, how many strokes take you need to swim 25 (no diving)? My current
stroke count is about 8-9. |

发帖数: 7276 | 50 Their team rarely practices breast stroke, although breask stroke was the
first stroke he learned( last summer in Beijing). He didn't spent time on it
this season. I was surprised by his progress in back and fly since he was
at around 32 s just a month ago. And suddenly he seems to have realized how
to do it and surprised his coach and us. But practice time wise, the ratio
is about 8:2:1:1 -- free:back:fly:breast
He has pretty good sprint ability, but initially I was concerned about his
