Starting with a principle from physics: It is easier to add stages to an already functional sequence than to go back and modify earlier steps
Looking at movement development: natural meaning, without instruction, shaped by our time moving in our world.
Stage 1: primitive reflex control. I'll spare you the ins and outs. they are autonomic, endowed to us. We are born largely under developed and these are the baseline of our movements.
Stage2: we develop connections up to the midbrain/higher levels. we begin to move based of desires, intention, e tc. Gaining head control, gaze, progressing up too standing and walking. The development of these movements is based on teh inhibition of the stage 1 patterns. They don't disappear, that are inhibited.
Stage 3: we gain access to the upper brain. We are conscious of our movement, creative adjustments, etc. Final develpment is based on the movements and inhibition of the lower patterns.
That is a very rough outline. the main point is we develop by not only gaining structural strength but also by inhibiting patterns that may be counter productive to our ability to move. With relation to skiing, the autonomic patterns are still there, when we are in survival mode they fire. They may not appear int he same format of extremity sequences but they interfere with the coordination of our movement. Because they are largely directing spinal orientation they interfere with the dynamic control of the spine. The spinal engine theory supports tthat the most efficient movement incorporates as many segments/joints as possible. I was looking to see if there were any training programs designed to look at spinal mobility/coordination. there is plenty of training for strengthening, but are there any land based or on snow programs looking at educating a person on these interfering patterns and how to identify and inhibit them. thanks for any feedback. hope that is clearer. I thought looking at MA for the trunk and spine would have been helpful, maybe it was just confusing. Maybe this is ridiculous all together.
There's the issue of "functional tension." This term gets bandied about amongst ski instructor circles. Here are three maneuvers that illustrate what it means.
Two people face each other on flat snow. One is on skis (Skier); the other is not (Boots). Boots grabs Skier's ski tips and pulls them forward. Skier flails backwards. Boots asks Skier to tighten the core, naming this "functional tension." "Tension" because the core is tight enough to withstand another jerk; "functional" because the core is loose enough to move the right amount to not flail backwards. Boots pulls skis forward and backward. Boots continues pulling and pushing the ski tips until Skier is able to balance and not flail. "Functional tension" has been achieved.
Another one of these: Boots has Skier hold two poles horizontal out in front of body. Skier assumes "functional tension" in whole body, including arms Boots pulls poles forward and pushes them backward. Skier's skis need to move fore and aft with the poles; Skier's stance on skis, including arms, should remain stable. If this works, Skier has "functional tension."
One more: Skier stands with poles horizontal, only this time stands in a countered position; one ski a little forward, same for hip, shoulder, arm, and hand on that side. Boots attempts to twist poles and thus pull Skier's upper body to either side out of that countered position. Skier's task is to maintain the countered stance, and not allow the arms no core to turn to the side. If this is successful, then there's functional tension there.
Functional tension is not static when Skier skis. Skiers upper bodies and lower bodies move in relation to each other. But functional tension should accompany that movement. Point of all this: skiers who ski with functional tension are going to be more balanced throughout their turns as they encounter unexpected terrain challenges.
Something else happens, too. The core, with its tension intact, becomes a strong active player in the body's actions as a whole. It stops being a passive reactor.
Is that something like what you were looking for in the blue above?
