First of all, I'm glad you guys could download the higher resolution .avi. Its too bad the compression on V1 will not support the videos we took, however, first, I have posted a summary of the training sessions over on NASTAR
This is actually taken from the conversations on the hill, its towards the end of that thread.
I will give you some brief answers to your posts, I don't want to totally let the cat out of the bag as that will take all the fun out of this exercise
|It looks a lot like the pumping we were talking about a month or two ago. It's almost a skating move to accelerate toward the new turn. It results in a downhill ski that moves away from him and a step up onto the uphill ski. You see it in the changes in stance width. As he comes out of the bottom of the turn, the downhill foot moves away in a skating fashion and he steps to the uphill ski. He is, very possibly, and to HH's horror, on opposing edges for a moment as he is still pushing off the old downhill ski and starting to engage the uphill ski on the downhill edge.
No, not at all. He is not pumping, letting his outside ski rail or move away from him, he is standing VERY TWO footed and carving both skis very precisely right up to the release. What you do see in the sequence where he comes off the "Elbow" and is making an extreme direction change onto a flatter slope is a SEQUENTIAL EDGE CHANGE.
It happens. But let me say this, at the speed he is going and in the video you can't really tell (not even close) is that he moves through the sequential edge change faster than most of use ever do our simultaneous.
I never got a chance to take a close look at those particular tracks so I can't tell you what those tracks looked like but by and large his edge change was incredible fast with no flat spots, just edge to edge. Next chance I get I'll photograph the tracks of a WC'er who pulls one of those sequential moves just for reference.
Let me say this with all assuredness that Erik is not thinking about how to turn. He just turns. He may think about what happened on that last run, analyze it but during the run he is looking ahead and skiing the line his eye presents to him, in real time.
|I think you're setting up how his core/waste is driving the transition, but I can't quite see it.
NO, we are not setting up any WS here. He is not a WS student past the Tai Chi he studied briefly with TommyK a few summers ago. How that has affected him, I did not ask him.
|I agree with Greg, above that last red gate his transition is different. He doesn't get full leg extension, he's later, and he quickly rolls both skis over. Maybe the course straightens out, maybe he's late. His upper body seems a bit stuck.
Careful, you are not seeing the whole turn. Just after that great simultaneous edge change he indeed gets extended. Right after this gate, however, he was able to tuck the rest of the way in (high tuck, never a low tuck). So, yes, he is about to ski a straighter line requiring less edge angles at the apex of his turns.
Lastly, where do you guys thing the greatest part of his direction change is happening? Above the gate? At the gate? After the gate? I wish I had more pictures of his tracks. The tell a fabulous story. I will give you hint, however, for the most part, not all the time, his inside ski and outside ski tracks were about the same depth in the snow, the fall aways being an exception I noted.
Keep going,,,, Why not? After all, he is ONE OF THE BEST GS SKIERS IN THE WORLD.
|But then below the red gate, he seems to get it back. Just using a lot of quick pause/plays, it does seem like his waist leads the way out of that turn and his skis quickly follow into an abrupt start to the next turn.
Looking at the stills on the NASTAR forum, I do notice how his back generally looks rounded, with the hips a bit forward, which you've mentioned is part of waist-steering.
Okay, here's the deal. If you any of you got the chance to stand 5 feet away from Erik and different sections of the course, at the speeds he is skiing, you would all realize that of course he possesses a very strong core and IS using it in his skiing. It is part of how we all move. I won't take this into any technical debate, however, yes, he rounds his shoulders (hollow chest) and has a very straight lower back (see Tommy's last post in the WS thread). This is posture, alignment and stacking. At those speeds, those G's the elite skier simply assumes the strongest possible position. Why? Because they HAVE TO or the will crumple under the forces. So does some of his skiing apply to what we (the MSR Team) talk about, most certainly. Does he waist steer. Not consciously and I'll bet if you ask him or TommyK, absolutely not (at least not to the full extend of its ROM). BUT, that said, again, at those speeds, those G's, the racer simply doesn't have time to DO too much, they do what they NEED TO and that's it. For Erik it is second nature, for you and me - forget about it,,,,
