Thank Hitter. I do have that info someone on my hard drive. I point to it often times when a young aspiring pitchers parent insists that IF the child wants them to pay for lessons, they MUST practice throwing 4-5 times a week. Its been my experience that as this study states, overuse is the number one cause of shoulder injury in the windmill motion........
The fact that external rotation is the primary "actor" in overhand throwing, and internal rotation is the primary "actor" of the windmill pitch helps us understand the differences in the motion. As the over hand thrower releases, the arm/hand turn away from the body. Where in the underhand motion the arm/hand turn INTO the body.
So the study makes sense from the point of view that external rotation injuries are most common in overhand throwing and internal rotation injury is more common in underhand throwing.......
Thanks again for posting that..........
