我比较喜欢另外一句: 先BALANCE了再TURN.

that's how impulse slips sway啊牛爷!

turn和balance应该是同时发生的我认为。你balance on edge,这就等于load。雪板被load,进入反向camber,这是turn的基本动力。在此之前你恰恰应该是不balanced,你的重心在向前和向下两个方向上领先于雪板,是人板分离的,是身体往山下斜着摔出去的,这才会有balance on edge时强烈的load,有一个momentum对雪板的撞击效应,所谓impulse。balance好了再turn,那是用side cut转弯哈。


另外后脑兜过去什么的真不是我说的。我还不到那个水平有那么明确的体会去说出这个来吧。我不过是重复了几次而已。

说的再具体一点,表盘法,你事实上只在一个弯的2到4点钟是balanced,是人板合一,板转push你转。4点之后你就要off你的板板,往新弯里去。完了6点钟,你在新弯内,板在neutral,完了下个弯12到10点钟,你要转板,把自己重新搞回balanced on edge的状态。这个状态也只延续3个刻度,你又要off往下个弯去了。Csia为毛把一个弯从8点画到4点,而不是12到6点?这就是道理所在吧。

偶觉先有BALANCE ON NEW OUTSIDE EDGE哦。不是很大的EDGE,但要早。
然后才有你说的这一切,就是去LOAD。 ...

that is how impulse slips。。。

最近是有点跟牛爷干上了这是。私聊可以躲,公聊没得躲哈。继续impulse的讨论。滑雪是嘛,撞墙回头!坐缆车拉到山顶积累的笔直向下的势能,通过往两侧撞墙,转化为左右盘旋转弯的动能,in style,而不是一路刹车对抗到底。这是理想状态。那么fall line就是墙之所在。物理实现上则是到了fall line立刃,板压弯,板把你撞回来,横走。这个没什么异议吧。

那么好,做个实验,踹墙:

方法a,墙前面站住,约一腿长距离,提单腿,金鸡独立,站稳了,完了窝心脚踹丫的。

方法b,墙前面站住,约一腿长距离,提单腿,金鸡独立,完了往前压重心,身体往墙上倒,同时窝心脚踹丫的。

哪个力量大,动静高,震动效果显著,不用试也知道吧。common sense哈。

第一个就是平衡住再load,第二个就叫有impulse!

回到滑雪,请看大屏幕,美女施大小姐出场:



这就是前压重心,身体往墙上倒。



这就是有impulse的窝心脚踹丫的。

唯一费解的一点,是滑雪,如果真用日常活动比喻的话,其实是蟹行,横着走。所以滑雪所谓向前,不是脚尖也就是板尖指向的那个前,而是偏转一个角度往坡下。

回到鄙人数年前的老段子,踢球!

请看下图:



图中第一第二帧在干嘛?在前压重心!这时的重心,绝对在脚前方某处,领先于脚往球的方向压过去。这也就是你滑雪时,8到6点钟该干的事。

第三第四第五帧,抡腿,这就等于6到下个弯2点钟,你把腿转且extend出去。

第六帧,击球,这就是fall line!

你先平衡了再踢是啥,那叫弹球,不是踢球哈。

最后再请jfb出场。废话少说,回到踹墙的比喻,这个是往墙上倒身体:



这个是踹:



这就是impulse。

当然不是只有我一个人在混ski school。我还不是被混过的人忽悠才去的吗。应该也不会只有我一个人读过ron大师的书吧。为毛ski school里每次训练的老生常谈,ron大师书中近乎常识的几段大便宜话,到这里不但少有人理解,甚至被视为入魔呢?难道是我混的学校太差,教的都是破烂;我的英文水平又太低,理解统统偏差?

那么好不好各位受累介绍一下,您们ski school训练都谈些啥?你要dynamic,就完了?什么是dynamic,怎么实现的?

ron大师的原文我也引用出来,好不好走正道的各位给我指出,这里有没不同于我上面那些讨论的截然不同的意思:

Learning to smoothly link parallel turns, is similar, in an important way, to learning to walk: Both movements  involve committing to  a period of imbalance. Toddlers take their first unaided steps by falling forward, then catching themselves with an outstretched foot. That’s how we all learned to walk. Eventually, the movements come smoothly, and the moment of imbalance is imperceptible. Still every step we make for the rest of our lives begins with a controlled fall.

To begin a parallel turn from a narrow stance, you must also learn to make a controlled fall. The toddler falls forward, anticipating the floor’s support of the turn and the lateral force from the snow that will support you once the skis have engaged the snow.

Going into a traverse between turns is like bringing your feet together and standing still between steps as you walk. Each turn and each step is separated by a period of static balance. Fluid movement begins when you move continuously and directly from one step to the next, and from one turn to the next. Good skiing, whether it’s in moguls, broken snow, or a slalom course, isn’t a succession of individual turns- disjoint curves joined by lines and angles- but rather a  smooth thread of arcs that flow each into the next with no discernible break.

you must (and this is the hardest part) let yourself go out of balance and topple from the old turn, across your skis and down the hill, toward the centre of the new turn. How fast and in exactly what direction you let yourself fall is dictated by a host of factors that only experience can teach you to recognize and evaluate.

This whole business if scary for skiers learning to make parallel turns. Being out of balance is something they’ve worked hard to avoid. For skiers who have the judgment to know how much centrifugal force awaits them and when it will come, this period of premeditated imbalance is the source of one of the skiing’s great sensations; the weightless feeling of flying into the turn.

Skiing becomes much more interesting and fun when you begin to add a dynamic transition with a period of imbalance to your turns. It’s the gateway to high-performance skiing, and remains a key point of focus for expert skiers and racers throughout their skiing careers.


go out of balance,controlled imbalance,controlled fall, whatever,这就是管啥的impulse,强劲的load,最终dynamic的turn,的全部秘密了,假如真有所谓秘密的话。用走路的前压重心伸腿接住比喻滑雪,我都要听反胃了,在我们学校。这原来是着魔啊敢情。再次请教,您们混的ski school,平常都谈论些啥?为毛我看遍youtube上各种教滑雪的,江湖骗子除外,谈论的也无非近似的东西?难么您对发生在您们ski school里的那些谈论,确定是理解的吗?

赞。英文版的说的真清楚!
怎么练呢?

uphill edge to downhill edge,edge rolling。牛爷忘了已经。
