This is movement analysis of Technical Freeskiing in video below. (Scroll Down)

Korea Technical Freeskiing contest, short turns.

                                            Movement analysis of Top Level skiers.            
                                                             Skier 1
 Right turn, left leg, this is his better side. His hip is counter-acted and his upper body is more vertical. His inside arm and shoulder are leading in the arc.
Here on his left turn, right leg his upper body is leaning, his hip is rotated and his torso is rotated. This disconnects the skis from the center of gravity. The CG is moving away from the stance ski. This photo clip is less than a 1/100 of a second before he falls. This is typical of a skier with weak alignment or under-edged alignment.

Skier 2
This obvious "A" frame, is not good,  even through the release is really hurting his performance, what is amazing about these skiers is that they don't extend, which is what is saving their performance, very hard to do with these alignment issues. They'd rather stay flexed and transfer weight without a push, great job.
In the lower of the two frames, this skier is rotating out of the arc with his upper body, the ski isn't turning, the tail is washing out, so he has to help with his upper body, he uses strong body rotation to get the ski around.

Great stuff Harald. I really appreciate the time and effort you put into this analysis. It really helps me to identify the finer points (both good and bad). Art
