I lied. I'm back
I have no problem recognizing/ pointing out things with Harald's skiing if I think it's a legit point to consider. I'll take a look at the pics/montages you listed.
I just want to confine these comments to steering and blending in of steering to a carved turn.
I just want to make a comment in an attempt to clarify the physiology/kinesiology and effects of the movements.
Steering does not originate in the foot, ankle, or knee. It originates in the muscles and joints that rotate the femur.Steering does not originate in the muscles/joints of the foot and ankle.
Back a while ago on the PMTS forum (the infamous "Holy Grail" thread). There was a useful back and forth with ydnar who felt that steering need not originate high in the kinetic chain. He could originate steering from his foot. Actually, to be fair, I think he was trying to say that he "pointed his foot in the direction he wanted to go" and that this constituted originating the steering action in his foot and didn't necessarily involve actions higher up in the kinetic chain. I will leave it to the reader to take a look at the posts in that section of the thread:http://realskiers.com/pmtsforum/view...+pointing#2649
It ended up being a detailed discussion of the physiology and kinesiology of the foot and ankle. I think the main thrust of the posts was that the foot does, in fact, rotate a bit using the ankle joints (more outward than inward), but that it does so as a part of inversion/eversion or pronation/supination. The problem is the direction of rotation within these triplanal movements is always opposite of the direction of tipping for the same direction of turn. So that when the foot adducts (rotates inward), the foot inverts or edges onto the LTE and effects a turn to the outside. Likewise, when the foot abducts (rotates outward) the foot everts or edges onto the BTE and effects a turn to the inside. In reality, this is a moot technical point since the actual rotational input from the movement for any real steering is minimal. However, one consequence is that if one tries to steer the toes of the stance foot in the direction of the turn by using the ankle, it actually tips the ski off the edge that is needed to hoold the intended turn. The movement tends to flatten the ski and cause a skid. Again, restricting the movement to the foot/ankle, the rotational input for the turn is minimal, but the negative effect on edge hold is great.Steering does not originate in the knee.
I don't think there will be much argument about this. Generally the knee is viewed as unidimensional joint. I pointed out in an earlier post in the "Rotary poll" thread that there is some rotation of the tibia that is inherent in flexion, but again, this offeres no real input for steering. Further, I also pointed out the research suggesting that when flexion is coupled with any kind of wedge or wide stance the resulting displacement and rotation of the tibia is a contributing factor to lots of unhealthy knee stress. So, even if it did do anything for steering, it would have to be avoided.
That leaves:Steering originates in the muscles that rotate the femur.
So, the choice is clear there is inversion/eversion that produces edging and then there is rotation of the fumur that produces steering. If you try to combine or blend them fine, but let's be clear on the movements, and their very different origins.
I would also argue that the effects are very different. One produces engagement and edging, and the other produces skidding and rotation. When you are "blending" steering into a carved turn, you are simply saying let's skid a little to change direction. Again, nothing that I have said so far is a judgement. I'm just describing origins and effects.
If this is the result you want then good. if not, then bad. That is up to the user.
