Elastic energy = Pitch Velocity

August 26, 2009

I have already made the argument that the body generates the velocity of the pitch and not the arm. This article will continue to prove this point and give the pitcher a better understanding of how velocity is generated.

Dr. Jobe FW, Dr. Tibone JE, Dr. Perry J, Dr. Moynes D performed a case study called An EMG Analysis Of The Pitching Shoulder. This study is the proof that the accelerator muscles in the arm do not fire when the arm is moving forward. Which means the arm muscles do not activate to generate the velocity of the pitch. Here is a summary of the study. Read more

The arm throws the ball but does it generate the velocity in a 90+ mph fastball?

tim This question can stir up a big argument but there is only one answer. The arm does not generate the velocity. It only guides the pitch. Therefore the arm must follow the body and does not come into play until the body has done its job. Read more
