Lots to unpack. Here's a simple theory.
Wile E Coyote gets a rubber band and stretches against it as far as he can, then let's go. Zooom. The band contracts and Wile E. takes off.
Now take Wile E. and after he stretches the band as far as he can, pull the front anchor point violently with a large force. The band will stretch more than Wile E. could stretch it by himself.
Now stretch the band and then as the band reaches it's limit and the front anchor us moved, have Wile E. run against the pull of the band.
Turn the shoulders back against a forward moving and gently is opening front hip via external rotation of the rear leg. Creates stretch on the core.
At launch, push the front leg rearward against the pelvis to create a more forceful turn. Simultaneously, throw the barrel rearward via tTB to create an even bigger stretch. Then contract the core against the left turn pull of the pelvis to catch up with the hips.
Anchoring the rear leg may stop the pelvis from rotating.
What stretch does it create and where would the energy be released?
Check out how the forward "drag" or "skip" movement of the rear leg after it becomes unweighted and that the contraction of the femoris rectus pulls against the sacrum to counter rotate it so the spine can positively rotate. Frette's 1st law. This mechanism is how the body ambulates... the pull of the "swing leg" counter rotates the sacrum and the gear effect rotates the lumbar spine in the opposite direction.
Possibly, if the rear leg remains anchored or moves in a scissor, the pull of the femoral rectus (quad muscle) and resulting counter rotation of the sacrum, could have the same positive rotational effect.
WRT the bold...... The problem that I have with this is that it isn't very controllable it lacks stability and has poor direction.
WRT the Red....... The stretch is across the front of the body from the rear foot to the lead shoulder. There is also a stretch across the back from the lead foot up to the rear shoulder..... I do not understand the energy release question.
The force is being created within in the body the ground is merely an amplifier. Just look at the Jeter jump throw, it is all there if you really think about whats going on. Stop looking at it as JUST Fulcrums & Levers and include the Fascial System.
Fascia Lines are the intersections of the body - The Fascia Guide
The concept of Fascia Lines is a great way to understand how the body functions and how treatment can be optimized to increase mobility and functionality. The main principle is that muscles, no matter what they do individually, also affect tissues throughout the entire body.
