PIVOTING

the right place - arch of your foot
        Your ideal pivot point is under the centre line of your foot, just ahead of your heel pad.

        if it's forward on the ball of the foot or back near the heel,
        you will use hip and upper body rotation to help change direction. (Stand up and try it).

the right way  - turn the whole leg
       Turn your leg (all of it). The foot, knee and thigh should all rotate together.
       whether you turn inwards or outwards, our whole leg must be relaxed (unweighted).

       note: we hear instructors saying "turn your feet" all the time, but notice , if you only
       turn your feet, it is really hard on your knees and your foot rolls to the outside promoting
       skis to end up on outside edge, not what you want

the right time - when edges are released and legs are relaxed
      "Do you pivot first or edge first"
       the key is to not think sequentially because both are happening
       all the time no matter where you are in a turn.
       The easiest focal point is that moment you are about to
       change direction, when the edge is release and there is that momentary
       lightness and looseness in your thighs.

      If you do it one leg at a time it creates a wedge before skis become parallel again.

      how much you turn your legs at this point is up to you and the type of turn you wish to make -
      skidded, steered, or carved.

A腿八字的,是TIMING没掌握好。
上身转动的,是PIVOTING POINT没找对。

steered is something in between, it can be 1/99 to 99/1  发表于 2013-10-10 10:58
carved is to use the speed/momentum while on high edge angle to turn following the side cut of the skis  发表于 2013-10-10 10:58
my understanding is that skidded is the twist (for lack of a better word) of skis to change their direct in turn the motion direction  发表于 2013-10-10 10:57

是不是很明显是大学刚毕业的?:D  发表于 2013-10-11 08:34
omg, pitch, yaw & roll.  发表于 2013-10-10 22:41
since I don't believe in perfect carving, everything is a balance of the 3 motions, though I do believe the fore/aft should be eliminated  发表于 2013-10-10 13:06
and the fore/aft adjustment is pitch along axis of skis  发表于 2013-10-10 13:05
in (my understanding of) physics, pivoting is the yaw about the body axis, edging is the roll about the edge of ski(s)  发表于 2013-10-10 12:48
I think the turn type is the result of actions. pivoting is an action, edging is another, and there are many other actions  发表于 2013-10-10 12:43
