As most of you know if you've been following me on twitter (@PitchMechanics) I've been releasing some research on a couple athletes I've been working with here in my new setup at Prime Performance. I've gotten some great feedback but wanted to have a central place for everyone to go back and see the data, testing methods, etc. in case anyone wants to replicate any of it themselves.
Testing Method: After the thrower completed a full warm-up, we began to play catch with a weighted baseball. He made 15 throws with each ball (11, 9, 7, 5oz in this order) and the Motus sensor recorded the data. The first 15 throws with the 11oz ball were "warm-up" throws while the remainder were "shuffle" throws where the pitcher did a simple shuffle into the throw, similar to how an outfielder may make a long throw.
