The Secrets behind throwing hard!

What do hard throwers do different than you?

Dr. James Andrews at ASMI put together a study of low velocity pitchers to high velocity pitchers to determine the difference in pitching mechanics. It was a good feeling after reading this study because the same information coming from Dr. Andrews is the same information Top Velocity has been preaching for years. It proves why I overcame a rotator cuff tear and was able to reach 94 mph on my fastball post surgery.

What these high velocity pitchers where doing different was transferring more momentum to the ball faster and more efficiently than the low velocity pitchers. There was four significant differences and these differences did not start until front foot strike. This means it doesn’t matter how you build momentum but you must build as much momentum as you can, then when your front foot lands your front leg must stabilize and continue to extend back into the hips before ball release. This front knee extension mainly occurred with the high velocity group of pitchers. The next major component of high velocity came with maximum external rotation of the arm when the trunk was tilted all the way over the front foot due to the excessive amounts of momentum generated into front foot strike. The study states that the reason for this maximum external rotation is because

“Greater shoulder external rotation causes a stretch of the internal rotators allowing energy to be stored in these muscles, and creating greater internal rotation during the arm acceleration phase.”

This leads into the next and most important component of the study. This component is by far a major component of not only velocity but arm health and pitch location. The study finishes with describing the importance of early elbow extension and internal rotation once the arm begins its launch to the target. I can’t stress the importance of this component enough. I have to admit that Top Velocity has not focused enough on this component and doesn’t have it in the Ace Pitcher Handbook. This will be added soon!

Early elbow extension and internal rotation is even more important when throwing a football. This is because to throw a good spiral you must have early elbow extension and early internal rotation to spiral the ball to your target. I recommend using a football in your warm ups to help improve on this component. The key to getting early elbow extension and internal rotation is keeping the arm relaxed the entire pitching delivery. The main focus of the arm is to be in position to receive the transfer of momentum and to transfer that momentum quickly and almost effortlessly. The only part of the arm doing work is the forearm. It is holding onto the ball with the finger tips. This is what controls pitch movement and location.
