Aiden came to us this summer after struggling to get back to his pre-surgery velocity. He threw 40 healthy innings this spring but couldn’t find the upper 80s - low 90s velo that he had before surgery. After doing a MoCap during his first mound session a few things stood out. Despite very fast pelvis and torso rotational velocities, his arm was not moving very fast. The energy from his torso was not reaching his arm. Looking at his torso positioning at foot strike it was fairly obvious why. Early torso rotation will kill energy transfer to the arm and tank velo and consistency. In order to address the problem, we attacked it from both sides: rotate the lower half better so that the torso doesn’t have to compensate, and relax the upper body to delay rotation and increase elasticity. Aiden worked on it tirelessly for the 2 months he was here with us and in his last mound session was back up to his pre-surgery velocity. As someone who typically picks up a few mph in game, I wouldn’t be surprised to see some big numbers from him this year.

We’ve been performing MoCaps for all our college athletes this summer using our Noraxon | Biomechanics Technology Ultium Motion system. The system allows us to capture a tremendous amount of data such as joint angles, segment acceleration, kinematic sequencing, force and power production, and movement efficiency. Utilizing this information, we are able to help our athletes make corrections backed by data. Tyler Salisbury Baseball

When working with any athlete, but especially younger athletes who are not in the top 0.1% of body awareness the way some big leaguers are, you have to be aware of the fact that they may not be physically able to identify the feeling that you are asking them to. Starting them in the correct position via a constraint drill is a huge first step in the right direction, but ultimately their motor learning will be quicker and more permanent if they learn to feel the position for themselves. We will sometimes use the pantherteckat to give the athlete tactile feedback (via vibration) to let them know that they are in the correct position. This allows the athlete to move freely without constraint while still getting immediate feedback on where the correct position is. The athlete’s ability to recreate that movement without the feedback improves dramatically and quickly.

Huge shout out to our guy Tyler for throwing a perfect game on Monday in a 14-0 W. Tyler has been working as hard as anyone I’ve seen all fall and winter and deserves all of the success that he is having. Excited to watch him continue to dominate this year.
