所以才說你真的需要拍段影片來看看,不過我好奇一下,你認為要什麼樣的動作才叫收縮釋壓?別拿饅頭片喔,那個你看不準的,看一般整理好的滑道就行了。lelo 寫:不是。
懶得找影片了!norman 寫:所以才說你真的需要拍段影片來看看,不過我好奇一下,你認為要什麼樣的動作才叫收縮釋壓?別拿饅頭片喔,那個你看不準的,看一般整理好的滑道就行了。
所以說,你並不懂什麼叫做收縮釋壓的動作,你只知其一表象,卻不能明白其二內相。lelo 寫:懶得找影片了!
大致上 angulation 做的夠斜,轉換鋼邊時,身體也沒有往上升起,應該就是做收縮釋壓。
如果是像你影片那種小轉,據我所知,收縮釋壓滑不太出來這種小轉來。
上半身傾?norman 寫: 你看得懂我提到的正確傾的動作嗎?經過我講那麼久,能分辨出來嗎?
你自己先評評,好的與差的,不足的地方,讓我這眼力差的人參考一下,也讓一些眼力好些之人,評論你批評自己的寬緊程度norman 寫:我剪下這兩段動作,要不要先試試評下面這段影片內兩種動作有何差別及問題?

我再貼以前2006年拍的大轉彎的影片。也可以一起評看看。大家都評完了,我再為我自己評一段,來看看我們評的有何差別,要評要快,不要放馬後炮耶。

上身過度面谷且沒有動作,是錯誤的觀念。lelo 寫:上半身傾?
我滑雪時,速度快不煞車的時候,上半身正面面谷,是不晃動的。
標準的「中級平行轉彎」, I think there are rooms for improvement before calling it 標準 using CSIA standard. You pointed out there is timing issue (I agree). There are turn shape issue (I agree). I said there are pressure control issue (maybe that what you said about leg extension/absorb). There are also speed control issue in your short turn as well. Everything goes back to the very basic of CSIA. Is COM over base of support? You short turn clearly showed some problem in that.norman 寫: https://youtu.be/rBwz892GIEo
在這段影片有兩種不同的動作,但都能定義為標準的「中級平行轉彎」,前面的大彎是伸展釋壓,後面的小彎是收縮釋壓。都有正確的傾,但不夠順,雙腳的同軸轉動還要再加強。
前面伸展釋壓大彎的問題是,傾倒的時機點還不夠早,不夠快,如果能再快一點就好了,所以還看得出來傾的不夠順暢。如果能再加強這一點的話,動作會再更動態些。
後面那個收縮釋壓小彎,弧彎不夠寬,太窄了,感覺起來就是滑得很保守,如果能再加強傾跟刻線的能力,動作會更好。建議多練練收縮釋壓大彎,把雙腳的伸縮再加強,再倒多一點會更好。
In this speed and turn shape in this snow, why you call this "incorrect leaning"? With correct leaning, what could be the result?norman 寫: https://youtu.be/T1Z6Z__9rvQ
(先補述一下重點,當時我一直強調的是「姿勢歸零」、「提早壓邊」、「折腰即轉彎」這三個重點,今日一樣保有這三個重點,始終如一未變,當時我評的也都是依這三點來評論,日後才增加正轉、反轉、拉提收縮、正確傾)。
所以現在當然就是以現在的眼力及後面增加的去評論。
這段動作的「傾」是錯誤的。不是站起來再倒向另一個方向,而是在未站起來之前就要倒向另一個方。
雖然動作看起來不錯,有提早壓邊,利用折腰的方式來轉彎,但太早折股會使得轉彎動作被鎖死反而不靈活,所以會顯的轉彎很被動,雖然這樣滑一般整理好的雪道很輕鬆,但上饅頭跟鬆雪就完全不行了。另外就是髖骨轉動還是太少了。
先想想看要如何先把傾練正確,在未到彎尾時就要把身體往另一方向山下倒,同時折股收腿繼續倒到另一邊開始才伸腿。周而復始。當然,如果你要是會我的拉提收縮的方法,那就改練收縮釋壓,這個動作會更快完成,不過想也知道是不可能的,你是不能體會的。所以要是你能先把傾練正確,收縮也是不小的。
其他的就是你的轉彎力量不夠,要讓上半身帶動下半身,這樣的轉彎會讓你更靈活。所以如果要練會這方式,要先練上身反轉,然後再練用先轉上半身帶動下半身,最後再練上半身卡下半身的滑法,這得等你練到會上半身帶動下半身的動作後,才能明白接下來要練的動作。要是先會拉提收縮就好了,會有助你的姿勢歸零及動作矯正會更快。
她就是等這些資料然後放馬後炮。B2L2 寫:Ok, I'm going to type in English (sorry typing Chinese is really slow for me). If you don't understand anything, i will try to explain more in Chinese after.

For me, I think there are many basic things to work on, rather than focus on "correct lean". Maybe you think working on the final skill could solve all these problem.
Let's talk about leaning anyway. CSIA doesn't focus on "correct leaning" and "incorrect leaning". Leaning is a result of certain skiing or the desire to achieve certain things.
My understanding of your "correct leaning" is to lean you upper body across the ski to the direction of your new edge at the transition phase. Is this correct or not? Anything to add?
You agree with your "correct leaning", you could achieve early edging? In your mind, achieving early edging gives you what?
In this speed and turn shape in this snow, why you call this "incorrect leaning"? With correct leaning, what could be the result?
Yes, CSIA always focus on turning with legs. However, I don't see a major "turn initial by upper body in this video". With this speed, there isn't too much pressure to absorb either.
If you're suggesting what's the next steps on what this skier should work on, again, I would suggest working on improving the basic skill set.
所以我才說你看不懂內相,你舉他的影片,只代表看外象而已。
吹牛成仙,苹果是不能和橙比的。norman 寫:所以我才說你看不懂內相,你舉他的影片,只代表看外象而已。
我舉M.H的影片是因為他做的很小,但還是屬於收縮釋壓的動作。
下面這個做的比M.H還多一點,又比P.L少許多,但還是一樣是屬於收縮釋壓的動作,簡單的講,基本上無論滑什樣的動作,只要上半身及雙腳併腿的,頭的水平線看起來都沒有起伏的,十之八九都是收縮釋壓的動作。只有超大傾角才會有一點點起伏的動作。

這也不是收縮釋壓,慢動作跳的那麼明顯,你都看不出來?norman 寫: 下面這個做的比M.H還多一點,又比P.L少許多,但還是一樣是屬於收縮釋壓的動作,簡單的講,基本上無論滑什樣的動作,只要上半身及雙腳併腿的,頭的水平線看起來都沒有起伏的,十之八九都是收縮釋壓的動作。只有超大傾角才會有一點點起伏的動作。

從你的回文來看,我們就著重在兩個問題點上就好了。B2L2 寫:Ok, I'm going to type in English (sorry typing Chinese is really slow for me). If you don't understand anything, i will try to explain more in Chinese after.

關於這段影片的動作,你的建議是沒有錯的,但什麼是基本技能?對當時的我,我認為最基本的技能就是「姿勢歸零」、「提早壓邊」、「折股轉彎」這三種。所以往後幾年我還在強化這三個重點,我在2010年之前所拍的影片中,我就自認「姿勢歸零」沒有做好,到2011年自認「提早壓邊」到盡頭了。2012年則是因為靈感體會到「拉提收縮」的動作而修正「折股轉彎」這個認知,因為「拉提收縮」無法像原來的「折股轉彎」這做法去完整的做到「折股轉彎」,所以到2013年開發出「正確傾」來改善這個「折股轉彎」的做法,其實我的進步確實是經由實驗跟一步步研究進步上來的,眼力才會這樣增加上來。B2L2 寫:In this speed and turn shape in this snow, why you call this "incorrect leaning"?

你自己怎知你滑時是什麼模樣,lelo 寫:上半身傾?

我有時會追前面的日本人,就盯著前面在滑。pku 寫:你自己怎知你滑時是什麼模樣,
在大部分運動時,自己是看不見自己真正做什麼,所以拍片是大部分運動訓練的方法來分析給運動員自己看lelo 寫:我有時會追前面的日本人,就盯著前面在滑。
