2/ Both pitches are the same velocity with the same athlete. Look at the pink skeleton. The shoulders tilt back during leg lift, and as the delivery progresses, the front of the pelvis works uphill. You may be creating tilt early, but what position is it putting you in later?

1/ Is spinal tilt killing your extension? 🧵 Pitching coaches have preached the “spinal engine” for years—and for good reason. Movement of the trunk can play a major role in creating rotational velocity. But there’s a problem: more spinal tilt isn’t always better.

If you want to build the most advanced and affordable pitching lab in the world, send me a message to set up a @kinebase demo.

Velocity is a receipt, not a reason. It tells you what happened. It doesn’t tell you why it happened. Two pitchers can have the same velocity despite creating that velocity in very distinct ways. One gets there with an extremely deep flip up of the arm path while the other gets there by creating more force in a linear direction. If all you're tracking is the outcome, you can't tell them apart until it's too late. Ball flight data (velocity, movement, spin) should not be our driving factor when trying to create sustainable changes. That’s why @kinebase doesn’t view kinematics, ground reaction forces, and ball flight as three separate systems that need an API. KineBase tracks all of them within seconds with no additional technology needed.

My question is how can we measure it on a force plate mound that is turf and guarantee it’s accurate compared to a real mound. @kinebase ‘s force prediction models are predicted, but through proprietary methods and have been validated to 98-99% as accurate as AMTI. I don’t believe the goal is “accurate measurement” as much as it is accuracy in terms of what data translates to the game environment.

Last day in house at @PDPAthletics yesterday for New Mexico State LHP @BradynBarnes5 who had a sick summer capped off by an electric Live-AB session. Bradyn topped out at 91.4 during his first pen of the summer. We spent the first few weeks working on how he moved based on his @kinebase motion capture and putting him in a position to allow the back hip to internally rotate. This helped improve his direction allowing him to produce more force behind the baseball. With this, the fastball shape started to improve and create more IVB on average. Once Bradyn had a more consistent FB profile, he added a one-seam sinker to utilize seam shifted break and create more arm side run. He also improved the slider velo getting it up as high as 90mph. Down the stretch once he was moving more efficiently, he started letting it rip. He averaged over 92mph and was up to 95.5mph multiple times in his last pen and live. Bradyn put in some incredible work this summer and looks set up to be dominant this next season.

You don’t need an 8+ camera biomechanics lab and a force-plate mound that costs $100,000+. But you don’t have to settle for iPhone-quality motion capture either. @KineBase gives you portable, lab-quality biomechanics with predicted force data at less than 1/3 the cost of traditional lab-grade systems. 3D kinematics. Predicted GRF. Joint loading. Muscle segment activation. Force vectors. Lab-quality data without the lab costs. Don’t settle for less. Set up a call for more info: ro.am/KineBase

Force plate mounds aren’t as accurate as they want you to believe. While the data is accurate, the situation isn’t. A pitcher can’t reliably move at their maximum speed and force output throwing on a surface that shifts under the load. This is why @kinebase predicted model will actually be a more realistic representation of ground reaction forces because you can throw on a real mound. Real data in a real environment.

Preston Abel gained 3mph this summer, and all 3mph came in one bullpen with one cue. Leave the back foot attached to the rubber. It helped him shorten his stride length and avoid his back leg collapsing on his front. @kinebase gives data in real time to make corrections in real time.
