2. so, the general advice seems to be that - even for short radius turns - despite the short amount time available to make that next turn - i should be using my femur/hip joint to be making the turn.
I will go ahead and try this and other exercises suggested in this thread and report back.
In my earlier respose to you about the use of the hips, I focussed on the value of rotating the leg in a stable, non-rotating hip socket. Reading the thread again, I wonder if you are perhaps thinking of another hip movement.
Notice how we lean into the turn when we go around a curve when riding a bicycle in order to balance.We do exactly the same thing in parallel skiing. In technical terms our center of mass must be closer to the center of the turn than our outside foot. This is referred to as "inclination." Now when we initiate a new turn, one of of tasks is to "switch sides". In other words, if we are steerig a turn to the right, our C/Mass is inclined to the right of our feet; if we decide to turn left, we must get our C/Mass to the left of our feet. This is "the crossover".
OK, now for the hips. Although the "center of mass" is not a body part, it is frequently located in the general area of the hips. When teaching students to initiate a new turn, instructors frequently get students to bring the hips forward and ACROSS the skis to CROSSOVER and establish a new inclined position required by the new turn. Hips used in this context really means a forward/lateral movement of the whole hip structure, rather than the rotational movement of the femur in the hip socket. ( both movements may well be ocurring simultaneously, however.)
All parallel turns, regardless of radius, require a crossover and a movement of the hips ( C/MASS) to the inside in order to balance. BUT, the amount that is required depends, like so many other things in skiing, on your intent. I believe you say that you are trying to make very short turns, tighter than the width of a cat track. You also say that you feel there is not enough time to move to the inside (I`m presuming that you might be referring to this lateral move I`ve been describing). Well, you are probably right! This turn does not need (nor allow) for anything like the amount of inclination required in a dynamic parallel or GS turn, for example.
So when you feel that there is not enough time, your are, in a sense right on. And again, when you feel that there is a lot happening with your lower legs, that is also good. Getting on top of the pain problem is important, of course. And exrcises to improve rotational leg speed, and edging through angulation will be helpful.
So -rotating the leg in the hip socket/pelvis----yes
-moving the hip (C/MASS) to the inside----a must, BUT not very much.
