老大发话，谁敢不从，春眠中的诗人猫也得爬起来

发几张我最喜欢的两个艺术家的2013/14艺术创作新动态， ...

我想知道这黄线该怎么画？他的力都在外脚上么？受力线为什么不经重心点（大概在肚心）？
请指教。

这个妹纸好萌

咋看着不像双轴捏。。----------------------------XXXXX

仔细看了一下，好像还是双轴。 这个妹纸如果不是demo team的话，马上也该是了；

rotation的弊端还是逃不掉的。。。唉

不过在复杂雪况上表现还是比较良好的

双轴理论看的我云里雾里的。

瓶子滚动，两个瓶子加个蛋滚动，都可以理解，可是理解不了怎么跟两个Ski扯到一起？哪咤的风火轮还差不多

双轴就是不反弓，内脚承重，Ski转弯原理还是Steering或Carving吧？

steering 肯定不是的，carving可能会有，但是至少中级阶段不强调。 总的就是把人当成两个杯子，模拟那个形状。

让重力带着走，不强调外腿承重，实际应用应该是55分力。 站姿稍窄，肚子指哪就往哪走，外腿伸内腿屈，点杖为触地虚点。过渡不引身，采用屈腿换刃，（应该）不主动加力。

初学时使用类似于TFR的方式，一个弯一个弯分开来画半圆；然后连续。

看一个韩国的短弯，附HH的评价。在HH看来，韩国日本是一回事，大概老式的是一回事吧？



I am a big fan of Korean Skiing.

These are excellent turns, and excellent demonstrations,  however it is not "PMTS Direct Parallel" skiing. Why?

I am a big fan of Korean and Japanese demonstrators and skiers. I coached Japanese racers in the 70ies,  my years as a racing coach. I coached one skier from Japan, who finished in the top 10, in two different Olympics slaloms.

I like the skiing, it is precise, more so than North American skiers and demonstrators. However, it's missing two things to be PMTS skiing. If you look at the top of the arc, the tails of the skis are slipping or showing some pivoting. It is very well controlled and I am not criticizing it; because it is well done.

Again, we strive to engage the skis, by that I mean in PMTS we work on creating an angle earlier in the High C part of the arc. The other thing is the pole swing. If you have watched my You Tube videos, you know we try not to swing the tip of the ski pole toward the ski tip. As in the World Cup today, there is almost no pole swing, this is more efficient and requires less movements. Other than that, there is some minor hip rotation in some turns, but in general this is excellent skiing.

There are great movements here; flexing is the most obvious, tipping with the inside foot/ski first, also holding the CA in many turns and Counter Acting at the initiation. Excellent stuff.
