Flexion and Extension

[pku]

我沒有特別想要在up down這個動作上爭辯的意思，但只針對我說的up down範圍的含蓋意思，下面這張照片是從下面那段影片中剪貼出來的。

下面這三張照片，由上而下三張，分別展示了我說的，伸展→收縮→伸展的動作。

Up動作，一般泛指「站起來」的動作，但以伸展來說，其實不以雪地路線來說，以身體動作外觀來看，就跟站起來差不多，只是沒站起來那麼多，且保持腰部有折角而已。

Down動作，一般泛指「蹲下來」的動作，如下圖中可發現HH的大腿有抬起來/收縮的動作，收縮後跟蹲下來的動作也是差在，收縮後的動作，腰部是沒有折角的，但不可否認的是，這個收縮/吸收的動作，以外觀來看，跟蹲下的身體動作是沒兩樣的，只是蹲下的動作幅度較大，而收縮的幅度較小而已。

就身體結構動作來講，都一樣是有UP及DOWN的動作，只是多跟少而已。

說到用詞不同，在HH的收縮用詞叫吸收，伸展叫延展，名詞上的不同而已，但下面這個動作的性質，一樣是DOWN UNWEIGHT的動作。在動作上，他的大腿跟髖骨一樣有UP DOWN的動作，這個字只是認知不同而已，但身體的動作結構確是改變不了的事實。

所以我認為PMTS的動作中一樣有UP DOWN的動作，由下面這張照片可看出，他的上半身在外觀上還是有上來一點點又下去一點點的動作。說沒有UP DOWN的動作，否認大腿骨跟髖骨的開/伸展、合/收縮動作，只是有點自欺欺人的感覺而已。



Ski Practice (Feature 3): "Carved Short Turns", Ski Lessons by Harald Harb - YouTube

For CSIA, this movement is not call up and down, Up down is more of a vertical movement and this movement is more of a lateral movement. WE call the change of length of the legs flexion and extension. The PMTS call extension as a up movement and strongly avoid this movement.

I think when one need to ski faster with some more performance, up down movement need to be much less, at less that is what I am trying to do. If you see the Level 4 standard video, there is not much up down movement on the expect short radius.

I don't think the PMTS is the most modern techniques, every system are try to improve all the time. just the change may not be good for anybody. Personally, I don't like the way the Japanese and Korean promoting although their demo team members are all very very strong and good skier.

Yes, follow the shape of the sidecuts, up-unweighting can be eliminated.

PMTS is the newest teaching system in America, so yes, it is modern; though its "new" "weighed [leg] release" turning technique is no more than the good "old" "down-unweighting"; nevertheless, the teaching concepts are quite new. And in skiing, I don't think there is the "most" modern technique anymore. It has all been done before. Individual skills and capabilities maybe improved, due to the newer/improved equipments, but the parallel skiing itself has changed little since the introduction of the locked-heel bindings, which promoted then "new" technique "parallel skiing," and "skidded parallel turns" have dominated skiing scenes ever since. The break-through change came when introducing the "shaped skis" which promoted a "new" technique "pure curving"; nevertheless, some skiers have already carving before that, so it was only “換湯不換藥”. Next break-through came about is yours truly's Taichi Skiing's Flatboarding, which is to move the weight/center of gravity to control the skis, or "ride the skis," skiing started to change "shapes"/樣子,

The "shaped skis revolution" brought about the "pure carve" techniques, and what the newer "Rocker skis" would bring? Flatboarding.

Between Flatboarding and "pure Carving," which are situated in the opposite end of skills spectrum, lie the "skidded parallel turns," so there's no technique beyond them, only the "Tao of skiing"/滑雪之道。

Have fun, :)

Althought most members in all ski forums aware of Taichi Skiing/Flatboarding's story. I want to remind some visitors in case they got confuse. Taichi Skiing/Flatboarding is a low performance pivoting skiing skill. Most ski school are teaching this technique for beginner and intermediate skiers. Taichi Skiing/Flatboarding is inappropriate to consider same level as PMTS or CSIA.

Of course not, Taichi Skiing/Flatboarding has much higher skills and 境界 than PMTS or CSIA.

你說的對，因為用詞的不同或相同的用詞可能在不同的人之下，就可能會有不同的解釋。

經過這討論，我這兩天為徒弟重新整理我的心法教學及重拍影片，我決定去蕪存菁掉一些東西，直指我的核心技術練法，所以以後我的方法只有兩組字而已。

不管是練UP UNWEIGHT還是DOWN UNWEIGHT全都是使用「伸展→收縮」技術，因為我這核心技術只要會了，就什麼動作都變得很簡單了，一年內可以讓初學者靠直排輪練會DOWN UNWEIGHT技術。

所以我就不再用「UP跟DOWN」這兩個字來形容我的動作了。
