#1 Level4 Mock Ski-off ST

文章 norman » 週日 1月 29, 2017 9:40 am

分享一下CSIA L4考生的影片,之所以會分享,則是看到評論區有人留言一段蠻有意思的話,可以一起來看看。



Bill Armatage4 小時前
The skiers in this video are all good athletes. However they are handicapped by the movements set by the CSIA that they must demonstrate in order to progress through levels 1 to 4. They must extend to release their edges at the start of the next turn leaving only one option and that is to pivot or skid the skis throughout the new arc. They must also complete their turns with their shoulders and hips essentially pointing in the direction of their skis (rotation). This creates several problems for the skier. The tails of the skis skid out at the end of the turn (particularly at higher speeds). The skier can not tip the skis towards their new edges while in this position but rather must must extend to first release the edges. The skier must reverse the momentum created by allowing the body to rotate to this position (shoulders square to the skis) in order to turn the skis the other way. All these problems can be eliminated by using PMTS movements.






Bill Armatage3 小時前
At the start the trainer set three goals: (1) round turn shape (2) maintain turn shape to the end of the run and (3) manage pressure. No one, including the trainers, met goals (1) and (3). Why? Because it is impossible to achieve those goals using CSIA movements, namely extension (rather than flexing combined with tipping to the new edges, PMTS movements) to end one turn and start the next. In short radius you cannot create a round turn if you extend to initiate the turn. Extension causes the skis to flatten to the snow rather than tip on to the new edges. Furthermore extension causes the skis to loose contact with the snow. The skier now has only one option, pivot and skid the skis throughout the arc, rather than putting the skis on edge before the apex of the turn and using the shape of the ski to create a round turn. With CSIA movements the skis skid throughout the arc and only at the end of the arc do the skis go on edge causing a big hit or sudden pressure at the end of the turn.

我剛才又看到一段影片,底下依然是同一個人留言,我看了一下影片也感到一些困惑,我也放上我的,這並非比較,我的動作是屬於測試動作,旨在看看全身伸展時滑起來的效果如何,同時這個全身伸展也是一種獨特的練習,是用來矯正身體對離心力應用的適應性,然後做為下次再微調的依據,看來下次滑,身體不用伸展那麼多就行了。


Bill Armatage1 天前
Dan stems or places his new outside ski into a wedge at the commencement of his next turn on most if not all turns. This is not the example he (a level four trainer) should be setting for his level four candidates. PMTS movements would eliminate this wedge by holding the little toe edge of the inside or uphill ski while you commence to tip the outside or downhill ski to its little toe edge.



ps. lelo,我找你幫拍片的地方最少都是紅線以上,還有界外的off區,為何你都拍起來那麼綠呀?我的速度還比他快耶,哈哈。 :face (334):

這是應該是一個 PMTS Harald Harb 的擁戴者

其實只要是人都會出現這些瑕疵,有時雪質也有一定的影響

應該是。

其實我對裏面的回應是有意思的,過由不及,少不足滿都不好,適度便好,就如同有些人覺得這樣比較有幫助,有些人覺得那樣比較有幫助,坦白講,pmts太極端,我覺得不好。csia太平民也一樣有些問題,這些都到某個程度時進步障礙會比較大。 :face (343):

事實上我並沒有跟dan比較的意思,而是從他的動作跟我的動作,是還有細微不好,他的問題正如那位bill所講的,旋股過多,把屁股移出去,但也不需要像bill說的要完全沒有,如果biil在彎的結束點時,臀部不要再使勁,而是應該在翻腿往山下倒時就要停止旋股的動作,他的問題就完善了,只是多旋股又太早伸腿,這就敗筆了。

Pmts 的片是一般教學片,不會用滑得不好的方出來,而且也不會挑些太困難的地形
考試時雪況不好仍然要滑下來
Pmts 講得自己那麼厲害,那你又見什麼出類拔萃的滑雪人出來,來來去去也只是 Harald Harb

Harald Harb 滑雪沒有動感,更加談不上漂亮

我也這麼覺得,事實上我就是覺得他用他那一套雙直排輪設備練出比較極端的併腿滑出來,所以他的動作靈活性不好,老是縮著滑,這才是最累人的地方,硬是用過度面谷的方式練出平行併腿轉彎來應付所有的地形,所以他也沒有正確傾,所以看起來就如你所說的沒動感。

所以他提倡旱地練習是很有幫助的,但礙於他真的把雙排輪滑的感覺當作實際滑雪狀況,這就會產生很大的問題了,所以我覺得對進入中級應該能很快有幫助,但要快速進入高級,那就很難了,而要再進入更高級那就不可能,因為他也不會,所以他應該也是過度滿足當下現狀吧?另外,他下饅頭的技術動作性實在不什麼樣,看起來就覺得很硬拼。 :face (343):
