thumb problem
« on: July 22, 2008, 08:04:20 AM »
Hi,

I am new here, and I hope that someone can help me out.

I just started out bowling, and I got a Brunswick Fury drilled and fitted by an IBPSIA certified driller.  It is drilled fingertip style with finger grips and thumb slug (I think that is the correct terminology).

I am trying to throw a hook, and I feel like I am getting close to figuring something out, but I am having a pretty major problem with my thumb.  At first, when I got the ball fitted, I couldn't get the ball to come off my thumb.  The driller made the hole bigger, but I still had some problems with it not coming off.  I ended up trying the Brunswick thumbsaver and it immediately solved the problem with the thumb getting stuck, and it has come of clean everytime since.

However, after bowling probably 10 games or so with this ball over the course of the past couple of weeks, I've noticed I have quite a lot of pain in my thumb.  The pain is on the palm side just above the bottom knuckle of the thumb.  This is where the edge of the thumb hole meets my thumb during my swing. The pain comes from when I try to cup my wrist, and keep my wrist from collapsing when the ball reaches the bottom of my swing.  When I do this, I feel the pressure on this part of my thumb, so a lot of weight from the ball is focused on this part of my thumb by the edge of the thumbhole.

I've tried a lot of different ways of trying to hold the ball, but I always end up with this same problem it seems.  When trying to keep my wrist firm or cupped, the pressure or weight of the ball goes on this small point on my thumb.

Any ideas?  I'm just getting started, and I feel like I am missing something simple that is causing me pain.  If I could figure out this one problem, then my swing would be so much more fluid and easy I think.

It sounds like you are gripping the ball at the bottom of the swing. Just relax your hand and let the bowl roll out of your palm. A little bit of a bevel on the thumbhole may help a bit also. It sounds so easy but it does take practive to relax your hand. Once you start relaxing your hand a bit, you may need to add some tape in the thumbhole so that the ball doesnt fall out of your hand!

well it could be that you get a high pressure just at this little point.

I would see the driller again and have it fixed... or try to take down the edgy yourself. I know your pain... I need a very smooth edge with a nice widening and I do it myself.

you can also try putting some tape at this certain point.

Now I have some questions... just to make sure your problem is not from grabbing the ball:

is your hold completly relaxed? cause if you use tension to hold the ball you get a simple overstressing holding the ball...
the best way is to have a 100% relaxed grip.

Wish you the best.

Ok, I guess I am having a hard time understanding exactly where the weight is supported.  On the backswing, when it reaches the bottom of the swing, gravity pulls the ball downward.  My wrist is cupped, lets say, 20 or 30 degrees from my forearm.  With my hand up under the ball and wrist cupped as described, the ball wants to roll forward off of my hand due to gravity.  That is where my thumb, basically, catches the ball to keep it from rolling forward.

The only way I can see that you wouldn't have this pulling force forward is if your hand was directly on the bottom of the ball, which would require quite a bent wrist.

This is the idea that I am having problems grasping.  Forgive me for my ignorance.
