Re: Mass of Batter Question .

Posted by: tom.guerry (tom.guerry@kp.org) on Mon Dec 17 12:50:01 2001

Does the mass of the batters body , arms or hands give a hitter any more power ?
> Here is a hypothetical situation :

They both hit 80 MPH pitches perfectly on the sweet spot with the same launch angle and direction. All conditions of wind , ball , etc are the same.

My recollection is that if batspeed is the same,the duration of contact is such that mass makes no difference.Some have theorized that it could make a difference for aluminum with a trampoline effect where contact is longer,but I haven't heard of any evidence supporting this.

Mass,however can have the effect of increasing batspeed.If 2 torsos are rotating with the same angular velocity,the more massive one has more momentum which can give higher batspeed if transfer mechanics are equally efficient.Transfer mechanics will be influenced by how fast the bathead fires out,swing radius,when and if handpath straightens,etc.
