barrel/hand pivot point, a.k.a TTB

[julray]

What is your interpretation of what TM means here? What is being ignored?

My interpretation - Pujols is "ignoring" torquing the handle...

I believe TM and TTB is being ignored

Looks like Pujols is creating a slingshot action and the hands are creating a rotational point for the barrel to turn. I would say a good throwing action is created.

the back leg is the anchor. Why have you been reading on this forum lately that keeping the back heel anchored Is optimal. Very popular opinion yes?

to move 2 muscles together Fascia connects the two to create stretch and contraction. Muscles are the Fascial systems ‘Pedro’.

Back leg anchors the core? Ok. So then the shoulders would move. The core being on the opposite side of the pelvis from the legs means the pelvis is anchored by the legs and the outward rotation of the femur rotates the pelvis. If the pelvis is fixed and the obliques activate a twisting motion, the shoulders move because the pelvis is anchored.
View the video and maybe you'll see what happens if both the legs and the shoulders are open chain. The core can then only move them in relation to each other, not in relation to anything else.
Stretch a rubber band and release both ends...... nothing. No relative movement.

BTW anchoring the back heel is only useful to set up the front leg to apply torque to the pelvis by rotating the pelvis to be offset to the rearward thrust of the front leg.

So the fascia connects miscles somone will stretch as themoyher contracts? For instance, my biceps to my triceps so one will stretch as the other contracts? Same with the quadriceps and ham strings, stretch-contraction activation via fascia? Can you link a web site that describes this phenomenon?

Thanks, still doesn't help me understand why there is an increase in acceleration as the barrel is released to the ball. aka whip. If there was more of the circular motion you speak of the speed of the barrel head would be the same, or at least the rate of acceleration the same thru the swing, but the Ortiz data did not show that.

The bat is a lever. The distance from the handle to the barrel multiplies the linear speed of rotation. (The far end turns faster around the arc than the near end) Centifugal force multiplies the mass of the barrel.
Release is a completely wrong philosophy. No matter the potential energy, the barrel will start at zero mph if it is held back and then released. Better to have angular momentum. Then reducing the turning radius will conserve the angular momentum and accelerate the barrel.
Similar to the bullwhip.
Don't put the brakes on, pull sharply rearward on the handle.
Similarly, start the pelvis rotation and then sharply turn the pelvis by pushing the front hip rearward by extending the front leg.
The easiest way to increase bat speed at contact is to accelerate the barrel for a longer period of time....a running start. Start earlier and further from the ball. TTB and rearward barrel acceleration accomplishes this. Some say this means you need to start earlier. They are incorrect. The barrel accelerates away from the ball first, so timewise both are at the same speed. Swing path wise, TTB enters the zone at greater speed than a DNT swing at the same point on the path. Then TTB can accelerate even more while still on the ball path while DNT is running out of road.
Both swings start from zero mph, but the TTB swing has a longer path for acceleration. It doesn't enter the ball path until after the turn, so it's at speed with no commitment.

Do not force TTB, down to, FYB, use the larger muscles, create and maintain posture, the barrel will turn into the ball. BAM, one sentence maximum results. Just like the pros.

the back hip and back leg (at times) ERs during the forward move aka ‘coil’. At the very same time the front oblique is getting pulled diagonally backward while the body/pelvis is going ‘forward’ and staying CLOSED.



This posterior forward move of the pelvis is pulling towards the pitcher from behind. Stretching the obliques even more. As the obliques contract they pull the front hip open. The very end of this clip.



At toe touch, the back leg is anchored and is still not IRed(the back hip never IRs), it is stabilizing while the pelvis is pulled around the femur to its full ROM by the contraction of the obliques.

The back hip rotates over the femur during this phase. All the while the back leg stays anchored so a catapults base or anchor point can be created.

When the back hip reaches its max ROM the back foot everts and is peeled off the ground. The hips are a place to torque from, for both upper and lower body.



The hips and legs are the lower. The core is the middle. The rib cage and shoulders/arms/hands are the upper.

when you see the pelvis ‘rotate’ it truly just gets back to neutral in relation to the upper body. The core and upper on the other hand rotate a bit farther in relation to the pelvis and each other. That can be said for the legs to pelvis to the core to the shoulders, arms, hands and bat. Each piece rotates a bit farther than the previous piece. Ever notice that? That’s the deceleration of the sequence. Each piece needs to stop to catapult the next piece farther and faster than itself to give it speed and direction.

Doesn’t the top hand articulate around 90 degrees during TTB right at contact to add additional acceleration of the barrel?

You are describing pull off and cast Bobby.

Is Miggy casting ah I mean turning his barrel?

looks like a straight line to me.

I hope you're not a carpenter.
