View Full Version : Task velocity and mass (or ball velocity and bat mass)

Greetings,
I am looking for any (all) manuscripts that report studying the
velocity of a task (e.g. swinging a bat or throwing a ball) as a function
of the mass of the object being swung/thrown.
I am especially interested in references that have used Hill's
equation (Fenn and Marsh) or other similar equations to predict the
relationship between task velocity and the mass of the object.
My specific question is: How does baseball/softball bat mass (and
inertia) influence swing velocity?
While most studies on bat-ball impacts have looked at the mechanics
of the impact, I can find only one study that uses Hill-type equations to
incorporate the "biomechanics". (Bahill and Karnavas, Determining Ideal
Baseball Bat Weights Using Muscle Force-Velocity Relationships, Bio. Cyber
62,89-97,1989).
Have similar studies been performed in other sports?
Any general articles on predicting task velocity for a given mass
would also be helpful.


Please e-mail me directly and I will summuraize the responses.

Thanks in advance, Trey
