I am opening a new thread to discuss "steering" (ref:
http://www.goski.com.tw/forum/showthread.php?t=494)

Here is the PSIA definition of "steering" (in Alpine Technical Manual 2nd edition):

"Using muscular movements to aid the skis through the turn. Steering allows you to actively direct the path of the skis while responding to terrain and snow conditions."

I also like the definition found from a google book:
http://books.google.com/books?id=W16Lla ... CBYQ6AEwAA

"Steering: After you edge and pressure a skis, steering is everything else you do that applies a twisting force to your ski."

good move. what I have in mind is there r 3 method to turns.

1. redirection - pivoting (not steering)
2. brushing the side cut (mixing carving with un-even pressure on the skis tip and tails)- steering?
3. carving - control turning with how much bending of the skis.

what do you think? :face (334):

Skier888 - this is to reply your post (http://www.goski.com.tw/forum/showpost. ... tcount=104)

"I wonder if both of you know what is PMTS...."

My answer - Sorry that I don't know what brings you to this question. I don't know anything about PMTS. I agree with pku that some term might be interpreted differently in different systems.

:face (330): 這才叫進步快,模仿也容易。 :face (332):

雙腳有比上次緊閉多了,但這個動作,您的雙腳的動作及內外腳速度還不夠一致,這個問題是在於您的腰部上動作還不太足夠(需要大膽嚐試您認為不可能的動作),重心變換中,內腳也不要抬起來,要順滑切出去,新彎初期應有感覺重心有一瞬間會壓在內腳多一點點,這是錯覺,但實際是5/5站,需要先體會學會能運用到5/5站後,才有辦法繼續下一步,這些我只能儘力形容,但有時真的言不及意,這個坎需要您去跨過去,就是全程完全併緊雙腳,不虛浮任何一腳,那您後面就沒坎了。加油啦。 :face (330):

因為沒練過的人,是不能理解我的最後一個訣竅在練什麼動作,這是從9級靜態滑法轉換成9級動態滑法的關鍵方式,只有練我的方法才能理解的,我只是今年無法出門滑雪,不然我就有新影片動作也能得到證明的。 :face (334):

beg兄離上次第一滑,大概是4~6天左右吧?等到了第15天後的動作才是真正開始有看頭的(這是我預估的)。 :face (330):

要滑的像 beg 要有足夠的滑雪天數,相關肌肉要長出來,沒足夠的肌肉群,光懂原理也是滑不出來的。據我了解,應該是大腿外側的肌肉,而 norman 的練習法,並沒辦法鍛練到這個地方。

另外要更上一層,NSS 還需要提出如何 release edge 的理論,不然只能一直用 pivot 了 ...

您從來沒認真看過我的文章及練過我的方法,所以講了您也不知。

在我的文章內早就都有提到了,包括您說練大腿的外側肌力協調運用的方法(某篇心法文章內已提過,自己找囉)。

像我這次給beg兄的建議,也只有beg兄能看懂我的意思而已(我有在分階段講不同的重點)。

除非你有什麼獨門健身器材,不然用樓梯是不可能練出來的,以我的經驗,側著身體跳下樓梯會有一點效果。但還是不如直接練直排輪下坡,當然除非直排輪下坡也被你收為心法之一。

滑雪不需要出多少力氣,我們的肌力已夠用,最需要的只是正確協調運用練習。

還有,側著跳,是錯誤的動作,小心扭到腳。

至於直排輪只是用來練一個關鍵性的動作而已,所以不算是心法,只是一個最後的螺絲訣竅而已。

sitting at home 不需要出力氣,

滑雪不需要出多少力氣, depend where and how fast you ski. If you 練on the gentle grroom run, OK

真是令人無奈及誤解我只拍整理過的緩坡。:20070217213814:

我已提過,要找人拍也要天時地利人和的。:20070217222137:

Not sure how many people would understand it by reading them; I don't. Apparently, "steering" is a "borrowed" term; we should be able as well to find the meaning in its metaphor. How do we "steering" the steering wheel to turn a car? By pressing the steering wheel, while the steering wheel gives away and the control hand continues to move with the steering wheel without its own movement, and the continuous pressure causes the car to turn, that's "steering." In skiing, edging pressure is what makes skis carve, did I say I "carve" on flat boards? "Steering,"

Of course, good "steering," (so, it doesn't really matter what description of "steering" is when one can do it,) and yes, much better than Beg's.
