Most of them you could read the bib the whole way down standing at the bottom.
It's back to the slack line. How do they stay balanced on a slack line?? Is it with the feet? There's nothing solid there to go off.
Regarding slack line, it's a different activity with the goal not being to tip the feet or make turns, interact with turn forces, etc just because you can throw your arms from side to side to change balance does not mean you should. I would add also that your ankles can make much quicker and better balance adjustments then waving your arms ever will, even for a slack line
Dude, I couldn't explain to you how we walk let alone how one uses the muscles in the torso to balance on a slack line. Walking is not simple. People get Phd's studying it.
Explain to me the mechanics of why we ski better with poles. Even if we don't plant them as in gs and above. The body is not an erector set with motors.
One doesn't wave their arms around on a slack line unless necessary. That's not the primary mode of balance there.
However, you could look at the feet in slalom as being equivalent to the arms in slackline. It only takes a little "help" to stabilize.. Look at the kid in the second video on the slackline. He's just barely touching the instructor's hand.
Also, in skiing we have large forces and momentum which help to stabilize. Or can destabilize.
To say "it's different", in terms of slackline, of course it is. It does not use a different body however. This is why people train with stuff like that, or running up rock beds and the like. It develops the balance system and a lot of the muscles one needs. You can't get it all from just skiing. Well, you probably could, but it puts you at more risk cause you have to do crazier stuff.
They do not maintain a stable upper body with the feet! Yes, they have to use them to direct the course of the whole show and sometimes correct. In general, it may be a bit more like a gyroscope maintaining its stability. That does not require outside intervention - such as the point it rides on. It can be stable in space/air etc.
One leg slalom 2006. No hip dumping. Only one foot to use.
Got to 1:49 on this. The kid gets one or two fingers of support and can do much more. Same with the next one. Equivalent to balancing on one foot near a wall and being able to say put a finger on the wall every now and then.
