Left arm role in hitting
 

Hitting is often described as a straightening right arm pushing the left arm down and out in the downswing.
Wouldn´t the right arm hitting be more solid if the left arm was tightly linked to the chest during the right arm thrust?

If your left arm is tight to the chest then the Hands can not accelerate any faster than that amount which the rotating pivot will provide. If however the left arm separates from the chest , accelerates away from the pivot .....then more hand speed is possible. Be it from CF Throwout or Right Arm Drive OUt.

Since there is no #4 in Hitting, there is no pivot, so if you pinned your left arm, the right triceps would have to push the whole left shoulder girdle out of the way, rather than just the left arm.

Thanks for wise comments but I still wonder if letting the right arm pass the left one pinned to the chest during the downthrust would generate more power.

This is not true for 4 barrel hitting....

You state this as if it is "given"...can you support the above?

Does this apply to "lower planes"? Does this apply to angle of approach procedure only?

Why is more handspeed possible due to the separation? Given the main speed comes from the powerpackage....does the pivot supply speed or "positioning"?

Depends on the arrangement of the other components....

Yes it is. The pivot in 4 barrel hitting stalls very quickly in the DS. The right shoulder drives briefly down plane and then the right triceps fires off of it like a backstop. If the pivot continues, you're switting.

Action vs. Motion....the pivot doesn't stall....4 barrel hitter and 3 barrel swinger have the same startdown...easier to push a cannon ball that is rolling than one that is stationary...

Hitters pivot...period.

You're misinterpreting motion as action. The motion, after the brief right shoulder thrust, is solely a result of the right triceps. But if you spin the flywheel, you will be mixing pulling and pushing, against which Homer warned you! :naughty:
