Where Batspeed REALLY Comes From
     Force Vectors, Pursuit Curves & Other Confusing Subjects

by Coach Preston Peavy, Hitting Coach for VSI Baseball

Well, let's just upset everyone who teaches archaic methods once again.........I am going to try & keep this as simple as possible, while still filling you in on the important details.....

My High Speed Video Motion Analysis Studies & InfraRed Batspeed Measurements have shown to my satisfaction that batspeed does NOT come from an overactive TOP HAND.......See articles at www.peavynet.com/news.htm

Rotational Alone Does NOT Work Effectively! It goes directly against good physics & biomechanics.....Per my earlier articles, Swing Poisons-Back Foot Hitting and others at www.peavynet.com/news.htm,  when you attempt to rotate around a rear pivot point & rotate the top hand early, you kill any initial leverage you have through casting the top hand away from your body early, putting the bat into a completely un-leveraged acceleration position-you CANNOT overcome a 7 to 1 or up to a 10 to 1 leverage ratio on the bat-the weight of the barrel simply cannot be overcome efficiently when you cast it out early in the swing with the negative leverage present in a 32" plus bat........the bat is an INEFFECTIVE LEVER when you attempt to force acceleration via an early top hand rotation! There is NO POWER because there is NO LEVERAGE in the rotational forces you have available!
 
 Bat resistance has the leverage!


Here is where it get's a bit confusing, but follow me......
........REAL BAT TIP SPEED comes from LEVERAGED ACCELERATION of the bat for initial INERTIA accumulation & resultant EFFICIENT FORCE VECTORS to MAXIMIZE CENTRIPETAL FORCE to provide ultimate bat rotation AT THE RIGHT TIME through EFFECTIVE PURSUIT CURVE movements with the hands, made possible by BOTTOM HAND DOMINANCE & BOTTOM HAND EFFICIENCY with an end SUPERCHARGER EFFECT given by the application of SHARPLY APPLIED hip power LATER in the swing, more EFFICIENTLY APPLIED through a FLAT TOP HAND at approximately 70% to 75% of the swing..........

Did you get all that?....If not, don't worry...you will....SEE FOR YOURSELF! I have done a Motion Analysis of a top major league swing as viewed from the top. It is available on our VSI Baseball Video Downloads Page, as well as with larger images at www.peavynet.com along with my past articles on hitting.

FORCE VECTORS in this case are simply the SUM of the forces applied to the bat.......essentially through a fairly complex PURSUIT CURVE motion with the hands.......(Yes, I know math fanatics will pick on me for purity in this analogy, but give me some poetic license for description).....Because CENTRIPETAL FORCE is maintained (the force towards the center of the varying radius, complex rotation) the INERTIA that is built up in the bat through LEVERAGED early acceleration (pulling the knob to accelerate the bat-NOT rotating early in an unleveraged manner) is REDIRECTED into that "Pseudo or Non-Force" we non math types like to call CENTRIFUGAL FORCE....(remembering for the math whizzes that it is not really a "force" at all...but non math whizzes can think of it that way-learn why it is NOT a force at http://regentsprep.org/Regents/physics/phys06/bcentrif/centrif.htm).

Look at this hitting motion & notice the HAND PATHS & how they are NOT CIRCULAR nor are they PURELY LINEAR but instead are semi-circular in nature or more like a math PURSUIT CURVE.

This information isn't meant to confuse........Here is the BOTTOM LINE:
     The baseball athlete is pretty incredible.......he is doing the most difficult thing to do in sport.....
......and we need to help him.....

HOW?........BY TEACHING HIM MODERN TECHNIQUE based on good science, such as proven through our VSI Baseball HIGH SPEED Video Motion Analysis.....

PRO LEVEL BATSPEED & CONTROL is an ACQUIRED SKILL & TRUE ART......learning the PURSUIT CURVE movement with the most efficient FORCE VECTORS which is championed by BOTTOM HAND DOMINANCE to effect the most efficient LEVERAGED ACCELERATION & ULTIMATE BATSPEED simply requires INFORMED COACHING with TRAINING TOOLS that WORK WITH THE ATHLETE, not against him.............


Have your athlete Train with VSI Professionals, like Coach Preston Peavy in Atlanta, Georgia  to learn the RIGHT STUFF....... www.peavynet.com   smarty1@mindspring.com 404-909-8020
