Re: Mar. -- Proper use of arms in the baseball swing


Posted by: Jack Mankin (MrBatspeed@aol.com) on Mon Apr 2 00:37:47 2001


>>> If I pull the knob of the bat back towards the catcher during contact, how do I receive any of the strength benefits that the extension of my lead-arm tricep muscles may offer? I don't know how to pull back on the knob and, at the same time, explode forward with my lead arm triceps. Those powerful muscles have to be used for something right? Secondly, are you sure the pivot point is between the two hands? If that were the case, I would never be able to swing with only my lead arm. I took a whiffle-ball bat, held my lead HAND and arm stationary, then created angular displacement by moving thru the range of my wrist. My top-hand wasn't on the bat to help create angular displacement. What was my lead hand pivoting around if I didn't have the top hand on the bat to create opposing torque forces? Thanks for helping to clarify these items for me. DC <<<

Hi DC

Using the arms correctly is essential if a batter is to become a better hitter and rise above the average hitters. A batter will never develop sufficient arm strength that can generate the bat speed necessary to become a great hitter without properly using the rest of his body. The more the batter attempts to use the arms to accelerate the hands, the more he separates the arms from the power of the rotating body and shoulders.

In the swing of the best hitters, the arms are not used as much to generate energy, they are used to transfer the energy from the larger muscle groups in the legs and torso to the bat. Great hitters do not separate the lead arm away from the rotating body by extending the top hand.. In fact, far from it, great hitters keep the hands and lead arm back (across the chest) and allow the powerful rotation of the shoulders to bring the hands to the contact point. --- The top hand is not driving the lead arm away from the chest (this is forward arm extension and linear mechanics). As shoulder rotation starts to accelerate the lead arm and hands around the arc – THE TOP HAND IS PULLING BACK TOWARD THE CATCHER. This “pulling back” not only applies tremendous torque to the bat, but it also keeps the lead arm extended across much of the rotating chest as the swing is initiated.

As the swing continues, the back elbow will lower to the batter’s side and top hand will stop pulling back toward the catcher, and back arm will rotate with the body in the classic “L” position. The lead shoulder continues its rotation, which pulls the lead arm around the arc and back toward the catcher as contact is made. It is the “pulling back” of the lead arm that causes the “fishhook” effect (reducing the arc radius of the hand-path) and adds bottom-hand-torque to the bat. --- These are the mechanics of the great hitter that result in a highly accelerated bat through contact.

I hope that all of you are understanding that this is the main difference between the materials offered on Batspeed.com and the materials taught by other coaches who teach linear or their version of rotational/linear batting mechanics. It is fine to own and read that material for a general understanding, but I submit to you that those are not the mechanics used by great, All-Star caliber hitters.
