>>> Hi, all
I divide a batting method which is dominant in MLB into two types A and B.

A
http://www.geocities.jp/tokyomarlin/arm2aa.asf
http://www.geocities.jp/tokyomarlin/armswingac.asf

Bonds, Sosa, Griffey Jr., Ortiz are A.

B
http://www.geocities.jp/tokyomarlin/arm2ba.asf
http://www.geocities.jp/tokyomarlin/armswingbc.asf

Pujols, Beltre, Ramirez, Piazza(50% of MLhitters) are B.

I guess A is THT type and B is bow arch type. Is it correct? <<<

Hi Marlin

The computer I am using at this time does not have the program installed to run the clips you listed. But even if I could view them, I would have no idea what “bow arch” is. I am sure the same is true for most of the other board participants. Although some post has referred to the term, no one has given us a clear definition. What is its purpose, how it is applied, and most importantly, how it differs from other swing mechanics discussed on this site?

Marlin, the ultimate purpose of all swing mechanics is to apply forces to the bat that induces maximum acceleration around the swing plane. From your statement above, you seem to be able to say which hitters are exhibiting “bow arch” and which are not. Then hopefully you can define what forces “bow arch” applies to the bat and how they differ from forces applied by THT, CHP and BHT?

Note: Discussing body and muscle movements without defining the forces it applies to accelerate the bat is of little value.
