做道题吧，很久以前做过的。我今天忽然明白了点啥

俄截了一副图来说明自己的观点。只是菜鸟之见，发现错误立即改正：



CA根本就没有。有的话躯干和hips应该是朝向arc外侧的。



上图这位才算CA。

Stand about half way down the run. This depends on length of run and amount of terrain you can see. Generally I try to split the visible filming distance so I can get an equal number of turns from the front and back. Video at least 5 turns of the front, as the skier approaches, and then at least 5 turns from back, as the subject skis away. Pan smoothly as the subject passes keeping the skier in frame so we can see a side view. Use the zoom and OIS features if your camera has them. I suggest a max of 10x zoom which will help with image stability. If you need to exceed 10X zoom consider using a monopod.

• Is the stance width appropriate for the size of the skier?
• Does the release start by flexing the outside leg?
• Does LTE tipping lead engagement to the new turn?
• Are the feet pulled back at transition?
• Is the inside foot held back throughout the turn?
• Is there enough CB and CA and is the timing right?
• Is the pelvis included in the CB/CA movement?
• Strong inside arm?
• Is the inside leg flexed as the turn progresses?
• Does the outside leg extend naturally (no pushing) as the turn progresses?
• Does LTE tipping of the inside foot continue throughout the turn?
• Is the skier balanced over the outside ski?
• Is there a pole touch and how is the movement and timing?
• Alignment - watch the skis and knees carefully - does anything look like it needs go be tipped in or out?

Alexis Pinturault的cb和ca。看stance这部分的话，跟视频那位老兄很相近，内腿ski贴住外腿boot的窄stance，是HH推崇的。

瓜嫩刚发那个视频俄觉得跟HH说法完全一致啊，必须完全地压在外脚上，让外脚ski变形carving。这是pure的。

当你大幅度倾斜，到了内髋尖靠近雪面的时候，如果只有counter balance，你的内脚必然是承重的，至少5成。那么HH就要求你ca，向圈外扭动躯干和髋部。这其实就是你发那个视频里讨论的合理作法，即外腿的承重，是通过伸直外腿，扭动髋部来实现的，而不是膝部反自然的横向扭曲或转动整个腿部。

俄自己是手撑着桌子反复试了的，的确有效哇。瓜嫩也试试。

下一季大家是不是就都要开始练pure carved turns了呢
这个我喜欢
