I agree with what you said on COM.norman 寫:從你的回文來看,我們就著重在兩個問題點上就好了。
「COM」是什麼?一般我們稱為重心質量,而這個就是身體整個重量的中心點,中心點在哪裏?我們只能大概知道在腹部之間,其實這個重心是可以調整位置的,依不同的動作,重心位置會有所改變,少點折股,重心會往上移動,多點折股,重心會往下移動,身體向前帶動雪板會往前移動,被雪板帶著走會往後移動,大概諸如此類。所以我才會提倡有「拉提收縮」這個動作,重心移動由自己決定。這說起來又很複雜了,所以先講到此。總之重心的穩定基礎在於平衡,因為動作不同,而導致平衡點不同,這關係到個人能力上,這也是我提到的,動作正確,平衡能力才會提高,平衡能力提高後可以再調整動作練習,再繼續把平衡能力再往上拉高,這樣才會越來越進步。
Your「拉提收縮」for me is equal to the term "cross-under" that widely used in skiing. I don't find there is any big secret in your 「拉提收縮」, or maybe I missed something. Keeping the movement of COM under control gives you many benefits.
I think you're mixing too many things into your conclusion above and I don't agree on a few things that you said.
1) 總之重心的穩定基礎在於平衡
Chicken and egg problem. When you are unbalance, you body is busy to regain balance and have no time to control other movements (and one of these movement is to control your COM).
2) 平衡能力 could be trained. 平衡能力 for me means how to recover into a balance state after you go unbalance. If you don't go unbalance, there is no need to do any 動作. So I disagree with "動作正確,平衡能力才會提高". I would say "動作正確,then you go into unbalance less". I said 平衡能力 could be trained and it has nothing to do with any of your "correct movement". Riding on rollerblades, riding on a train, riding bicycle or just running could improve your 平衡能力.
3) 「拉提收縮」is one of the many skiing movements (or skills). It has its benefit but also its disadvantage. Learning cross-over and cross-under and blending them for the situation is more important for me. Cross-under is harder for people and some people call it an advance skill. But it really isn't the end of the game. You posted a CSIA demo team video recently where the 3 skiers aren't doing cross-over and you even ask why. Remember that?
I understand you like to explorer different things. However, I think there isn't too much unknown secret in skiing nowadays and picking one system to follow would be easier to advance one's skiing skills.norman 寫:所以我的小彎應該再加強平衡能力,那天拍這段時,我自認平衡能力還沒有第五天高,所以才會有第五天那種全身伸縮的練習動作,就是用來改善這個問題的,倒不夠就再倒多點,貼不到雪面就努力再貼近一點,當然,要是失去平衡我就直接倒下去啦,所以我確實是在練習中倒不下去,倒到失去平衡就側躺了,不過平衡就是要這樣練習,但前提是動作要正確才行,因為倒跟髖骨的轉動是很有密切關係,倒太多,髖骨轉動太少也不行,這就得建議正確的轉動方法及觀念了。
Don't agree on 「均壓」and that shouldn't be the goal for high-end skiing. The concept of regulate pressure is good.norman 寫:「正確傾」要說是在彎跟彎之間的「轉換」不能算是對的,它其實是包含在3點到9點之間的滑線,但這只是一個數字跟路線,我們都知道,其實滑雪時是很難用數字化去說明的,在不同的動作差一點,有可能是3點半到9點半之間,也有可能是4點到10點之間…等。所以在之前我有提到一個詞叫「均壓」,就是保持整個C彎壓力都是一致的說法,沒有反彈之說。所以用這說法來說明,例如我的體重是80公斤,上半C的壓力應維持在80公斤,所以要增壓來讓壓力維持,到下半C時,要是不處理,就會速度增加,速度增加,壓力就會增加,所以要減壓來繼續維持80公斤的壓力,而在減壓的同時就要開始進行「正確傾」的動作,又要做折腳又要往山下方向傾倒過去,聽到這裏,應該會覺得我講的有點天方夜譚,因為這兩者的動作跟方向好像衝突了,其實這並不衝突,只是未練到無法體會而已。
最簡單體會「正確傾」的方法是直直身體不做任何動作去刻線,完全用傾來刻線轉彎,這個PKU應該可能看我做過。
Again don't put you said as a top-secret skill. I don't think of 天方夜譚, in fact, all advance skiers are doing all of these. It isn't hard to understand what you said and what you want to do. Doing everything correctly with the right timing and coordination is the key.
When nobody agree that you're doing the high-end skiing, that's because you couldn't show that you could coordinate any of them together. If timing is wrong, we call it doing it wrong. But for you, you insisted that we don't have the vision and understand what you're doing.
Could you explain what you mean by 「避壓」? Absorb pressure for me is to eliminate it. 「避壓」 sounds for me is to prevent it and it disappear by itself. More details?norman 寫:為何我會強調「正確傾」這個動作,其一它能「避壓」(跟壓力最高點錯開來,就像打拳,對直拳過來,我只要一個側身就行了,就算讓對手打到,也是因為側身而沒有受到正面直接擊中,這兩種所受的傷害力度是完全不同的)。光這一點就值得學會了吧?
Ok, early edging. I agree with the benefit of early edging. For me, early edging is a skill for me to achieve and maintain rounder, higher speed turn with control. Different system has different way to achieve early edging. Is your 正確傾 to the only and best correct way to achieve it? I hold my question mark here for now.norman 寫:其二是能在最早壓邊,壓邊切入線是很重要的,它關係到平衡能力是增能再往上提升,所以等於只是一個翻板就直接進入切線了,能更有效降低側滑的問題。
其三,減少壓力影響就能增加速度,但這增加還是可以看自己去調整控制。
基於上列這幾點,我才會說,有正確傾跟沒正確傾,差天地之遠。![]()
CSIA's basic is always the 5 elements. I said the skier in the video could improve on all of the CSIA's basic elements. Every new drill, new movement, new skill is to improve the basic elements. We don't "create" one movement because of another movement.norman 寫: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。
Having a system to follow is still better than inventing your own, I say. :)
Even now, how could you said you don't have this "聽不進耳" 的問題? People (I think it was Snowrider) said your skiing is 2D only. You're missing one (or maybe many) dimension in your skiing. E.g. CSIA put lots of focus in steering, what's steering in your skiing theory?norman 寫:回歸原問題,為何我會說這影片中是錯誤傾來做區分?如果只是滑雪,其實是沒差的,如果未來想要練到高級動作技術,正確傾很重要。而在這階段提到錯誤傾是因為動作錯了,錯了就會導致C彎跟C彎之間的動作中斷,那時我也一直在想辦法克服這個問題,很明顯在重心轉換時,動作的流暢度被中斷了。但換作是那時的我來聽我現在講的這話,我會覺得很好笑,我的「折股轉彎」傾還不夠多嗎?這不是傾,不然哪一種叫做傾?嘿嘿,自己吐漕自己。坦白講,程度差太多了,這也是我現在幾乎不對他人評論,寫出來給有這些問題的人看,他們又看不懂,有何用?那就別白費力氣了。
I said there are many important things beyond what you (and I) are talking here. Those are really the high-end skills out there which better skiers are doing that we don't know. Maybe one day you will learn something new which prove what you insist now all wrong.
Last word (and I'm telling myself too), don't assume you know everything, keep learning with an open mind.norman 寫:至於我的建議如前面講的,先想辦法把正確傾學會及理解,這樣對往後的進步會比較容易有幫助,也可以少走點彎路。可惜如果沒有我現在會的「拉提收縮」這個動作,想體會可是極難的,因為那時我的動作是被板帶跑的,我覺得那時的我一定是不認同這個說法的,因為我做動作就能轉彎,怎麼會是被雪板帶著跑的,所以從這些一路到現在,我發現沒有學會的動作,永遠無法增加眼力及理解。還有就是不會挑真正動作好的影片,所以會被那些看起來好像很厲害的人所混淆。
Thanks for the long reply.norman 寫:我的回應該有針對你的問題吧?![]()
