Hey, Liquid......
thanks for the questions and nice definition and example of foreshortening. yes, that is what I was eluding to....the lack of 3d perspective or live MA, ect...
John,
I'm quoting your carefully worded MA from above:
"....Is there a slight pause in the hips moving into new turns? (mostly at the top of the course) tough from this angle, but body of turn and turn finish look a little bit back in the boots....(again, picking nits, here)....seems like you recover well and easily, though, by the time you are in your turn initiation....."
We can look for fore-aft movement in a frontal video of a skier coming towards us, and we can sometimes sense it, but this is a supposition. A side view (as you reference above) is far preferable when identifying fore-aft stuff. For these reasons I am always cautious in drawing fore-aft conclusions from a video of a skier moving directly towards or away from the camera.
I enjoy the clarity and insightfulness of your MAs here, so I am curious.... What did you see in the video that leads you to think there might be "a slight pause" in the hips moving down toward the camera at the top of the course, and again what did you see indicating the skier might be "a little bit back in the boots" during the body of turn and turn finish?
What I was pointing out, and questioning myself, is something I have noticed in both the synchro clip and this last clip on left turns. I should clarify that what is happening is only happening for a very small amount of time between the end of one turn and the initiation of the next....because of....either trained tactical movements or a vestigial movement left over from childhood. (and its only really apparent in the slow motion footage) I should also clarify that what I am seeing does not necessarily involve the hips in a purely fore/aft nature....its more a question of where initial turning forces are coming from in some turns, ie the upper body arm swings.
with the skis:
The more I look at the clips and others that he has posted, I think the movement is a tactical "jet"....squirting the skis foragonally .5"-1" at turn finish so they can start engaging the snow for the next turn.....I do not see an out of balance situation in the turns. when I say "a bit back in the boots", I mean perhaps on the heel instead of just in front of it at the end of turns...that aint much!
however, the position of the hands, and what they do are not symmetrical from hand to hand, turn to turn. (same in both vids). Left hand is consistently positioned away from the body more often and once in a while tends to drop just a bit back next to the hip.....while the right hand moves across the body a bit more and stays just a touch more forward. This seems to slightly effect upper/lower body alignment at turn transition when things should be lined up again. I see a more counter rotated relationship between the upper and lower body on some turns.
again, this could be tactical...those brushes are not evenly spaced and turns need to happen at different rates.
What I see and point out does not mean it is incorrect, or correct, its just what Im seeing and may be tactical in nature only. at this level, I should also point out that corrective adjustments in any positional relationship will be very very small, as movement patterns here are already at advanced levels.
Watching the other clips he has posted, I see very nice skiing, especially in recreational parallel basic turns, and shorter turns up through race turns. the drills shown for counter, outside ski engagement, inside leg flexion, outside leg extension, and other exercises are quite nice and good examples. TDK, I appreciate you putting yourself out there and going for it! What are you working on in your skiing this season?.....
incidentally, I do not see this habit repeating itself much in the other vids....though turns are longer....
