Pulling Down is Slowing Down

October 26, 2009

Alan Jaeger’s Long Toss program uses what he calls the “Pull down phase.” This is because after throwing the ball 300 feet in his “Air it out” program he wants you to pull down your delivery so you do not continue to launch the ball high as you move closer to 60 feet. The problem is this goes against the science of velocity.

Pitching velocity is the product of momentum and torque. You can read countless articles on this site about Momentum and Torque. Pulling the ball down during release prevents early internal rotation which is a key component to velocity as stated in the American Sports Medicine Institute (ASMI) case study called Comparison of High Velocity and Low Velocity Pitch Deliveries.
