I am grateful to have the opportunity to run a motion capture on 8 different collegiate arms. There is interesting data that comes from the dashboard kinematics and separates these three arms, for example. 1. The linear pelvis velocity is usually an indicator of higher velocity throwers without a bigger frame. 2. Pelvis-to-torso delay is also a common issue in college throwers and becomes an issue with higher velocity if there is too much of a delay in breaking the chain. 3. Common, but important, is the max external rotation throwers get while still in a considered healthy position. These 3 things are consistent with higher-velocity throwers. However, there is clear evidence that throwers prefer certain movements, such as pronation and supination, which tell a lot about programming and keeping arm health.
