标题: 一个很好的讨论carving和pivoting的帖子
一个我认为很好的讨论carving和pivoting的帖子。他们用的是那个晚上滑雪的韩国人的录像。基本上2方再讨论这个韩国人的滑法。当然了，讨论没有结论，相信每个人也会有自己的看法。有人贴过没？

去这个链接，可以去full version看到录像。

摘抄几段：

Carving
When he is carving he is riding the sidecut of the ski. So his only movement to turn is to tip his skis on edge and move over his skis with his body to stay dynamically balanced. And his only movement at transition is to see that his upper body transits from one side to the other in a balanced state of being. The turns are therefore longer and his upper body movements more lateral. He is laying down some good angles. He is going very fast. No braking. Controlling his speed by pointing his skis out of the fall line. The tighter he manages to carve his turns the less he will be accellerating down the fall line and the more controll he has of his speed. Only works to a sertain limit and takes a lot of muscle effort to do for a longer period of time if the slope is steep.

Pivotted
When he is pivotting he is over-riding the skis natural turn radius. Linking very short turns closer to the fall line with a pivotted turn entry and a hard edge set in the belly of the turn. He stays more upright with lower edged angles. This kind of turning is only possible if you get the kind of rebound he is getting at the end of the turn. His turns are in other words feeding on rebound and making use of up-unweighting. Some would call it down-unweighting but that is only a matter of how you look at it. Main thing is that his mass is being pushed up so that he can retract his skis and float through the transition. By tightening his turn radius and ramping up his rhythm he can gain more controll over his speed. This kind of turn is often refered to as a SL turn but in ski racing there is no difference between SL and GS. Both diciplines foundation block is carving.

Pivot = turn your skis. Carving = let the skis turn you.

A pivot is usually caused by femure rotation while a carved turn is produced by tipping the ski on its edge

还有很多不太懂的, anyway，值得一看的帖子。

PIVOTING 就是猛转踝关节
CARVING就是狂立刃
能这么理解吗？

窃以为是劈还是卡其实真的不是那么重要，关键是好看不好看，好使不好使。安全不安全，稳定不稳定。

说几点我的看法：

1, 小回卡不出细线，每个弧能刮出来一条月牙的宽沟，就是王道。

2, 猫狗上纯卡是可能的，但是不可能在每个弯100%做到

3, 没有一条弧是完美的。

追求柔和，均匀，省力漂亮的滑法这些虚幻的东西，远比爬在地上量是不是有条沟这些实际的东西来得实在。

it maybe is time to learn to skid more!

it is time spinning in circles

LOL

这最后一句和我感受的一样。

卡冰需要压弯雪板, 不然那个叫railway turn. 柔和稳定的压住雪板, 会在地上留下一条细线. 压的过程中板子的弯曲度变化会形成一条"粗"线, 如果没咬住,打滑的多了,造出一个扇面来, 那个不叫pivoting, 那个就是打滑了.

压弯雪板需要edging, 同时靠两种力道, 一种是离心力, 一种重力. 如果到达屁挨着地的境界, 可以认为重力基本不起什么压弯的作用. 考虑到COM转换是需要一定时间的(人力所限, 木办法, 但是很多人脑会忽略这个限制, 木办法, 人有多大胆, 地有多大产). 快速准确的建立下一个弧的平台是我等穷期毕生精力所需要考虑的事情(仁者见仁,智者见智, 引身也好, 收腿也罢,爱咋咋). 在转换时间段内, 你可以考虑:

1, 扭屁股的同时，不要把脚带转了。尽力保持雪板出刃时的方向不要改变
2，直接变化雪板方向，进入一个（不和原来的弧相切的）新弧。（竞技滑雪中常见）
3，调整一下身体的前后平衡，（把脚后撤或者上体前扑，恢复落后的重心，抑或不需要调整）
4，对于小回，保持上体的稳定于正直，重心可以被整体carry left, right, 但是不能左右倾侧）
5，新的内脚先落地，干那个什么initial turn的勾当
6，可以的板尖先落地，玩那个啥海豚跳
7，伸展你的下肢，准备踹下一个包的脸或者搓这一个包的背
8，基本好像木有了、

别人爱说啥，让人家说去，咱做不到，就这副德行了

瓜瓜的Comments 从来就是3级以上，为此我还专门在大白拍摄了一段准备回来后再整理放给瓜瓜看我们是多么的想瓜瓜，结果麦克不争气，把毛片丢了。当时的女主播是Echo, 男主播是猫狗帮大将丹尼斯

我觉得可以请Echo 和丹尼斯把当时的台词再背一遍
