正解，我刚想说这个。
但其实angulation就是个很反人类，反自然的动作。。。。。 ...

我理解的angulation是以腰为折点的，膝盖从正面看是直的

我也是这么想的，我觉得主动的应该是下半身。

如果主动送胯还会很容易导致一种“压屁股”的错误，绝对会 ...

lower body initiated anything is difficult to do. so to achieve the short turn gain, a potentially harming (to long term performance) movement is introduced to accomplish the form. And this is a good time to talk about CSIA's ideology of function determine form. I think I started to understand this phrase at the start of this season

angulation 有三种，hip,knee,还有ankle。现在都是用的hip angulation，其他的angulation 吃不上力。

神马，我同意JLUO 说的，如果膝盖，踝关节从正面看还是弯的，那真是反人类了

哈哈，另外一句话，BoS is placed between the resultant force and CoM，最近我也想明白点了。

就是我之前所说的，在没有knee angulation的情况下，腿部由下至上的方向可以看做支持力的方向，像个指针一样。这个理论用来分析视频很好用。

如果说是最自然的话，我觉得可以看一下日本的新技术，那个真的不是一般的自然。
尽管我感觉他们的实践效 ...

hybrid skiing with double axial? I like their ideas, great way to explain the mechanics. but I feel they are putting too much emphasis on inclination, so at a point the upper body is heavily involved in balancing. also, I feel the lag of gravity taking effect may constrain performance. again, great way to ski to a certain level

i agree that the world class racers may have angulation at knee, but they have great power and control. i still feel most of the top racers flex their leg but not pushing for angulation at knew.

like bull said, that is really against the nature, just like most of the competitive sports

firehwak2018 这句话对hip angulation是没问题的。貌似其他两种angulation在竞技中有应用，此处不了解
