By examining a bowlers hand, can you predetermine the kind of release a bowler has by noticing the location of the callouses (if he/she has any)?

Yes. Callouses are created by friction and will show wear that is created by the swing and release pressure or squeezing. Callouses show normal wear, as well as improper wear. If you look at average bowlers compared to most exempt pros, you would see a drastic difference.

No matter what, a bowler will create callouses. If callouses are created by blistering, generally they are from either an improper fit or a bad release, created by bad timing.

thanks for the replies. Guess what I'm asking is... do the location of callouses differ from say, someone who throws inverted as opposed to a full roller, etc.? I've learned the majority of crankers tend to have a callous on the pad of their index finger. Also, those who tend to 'hit' the ball with great frequency, have calloused fingertips. Those who knuckle have it on the back of their thumb and at times due to lack of bevel or stretched span, have one on the base of the inner thumb. I'm inverted and have begun to develop callous on the ringfinger - fingertip side of my middle finger as well as the index finger side of the tip of my thumb. I do not blister (actually never have)

Yes.

This is usually true when the bowler is going thru the ball more vs rounding it. Going thru the ball causes our hand position to be more directly behind the ball (or slightly inverted) causing pressure on that point. Going around the ball creates a different pressure point on the hand.

Here's a great explanation from JustRico defining this motion.

quote:
At release, it is where the fingers are, in regards to the thumb, in reference to a line perpendicular to the foul line, that create PAP coordinates.
If the fingers and thumb are in line, there will be very little if any, vertical coordinate. The longer the thumb stays in the balls, as the fingers rotate around this line, the more the vertical will go up. Also, if the fingers are on the outside of this line at release, this will cause a lower lateral, as well as higher vertical.

When the fingers are more on the inside of the line, generally the thumb will be on the outside, which can create an earlier release and a lower vertical coordinate or an inverted track.

Hope this makes sense.
