Defining Long-Toss

Recently, a third study was published on long-toss which brought to light some interesting data. Pitchers, PCs, and ATCs with five MLB teams completed an anonymous survey on personal use of long-toss and their perception of distance and throwing mechanics. The results of this survey show that player...

Computed Muscle Control Analysis of Pitching Mechanics

Continuing with our validation of a Forward Dynamic analysis of the pitching motion from last week (Part One), we had run through the initial stages of the simulation pipeline to have an accurately scaled model that is tracking the recorded kinematic motion and associated force plate kinetics closel...

Comparison of Elbow Torques Between Pulldowns and Pitching

When ASMI’s weighted-ball study Biomechanical Analysis of Weighted-Ball Exercises for Baseball Pitchers was released, we were excited for many reasons. One of the big reasons was that we would be able to replicate this study. We wrote about that study at length in our article Weighted Baseball Resea...

Forward Dynamic Simulations of Pitching Mechanics

Previously at Driveline Baseball, we featured an exciting and informative three part series by Dr. James Buffi on his work toward an innovative new training and elbow injury prevention approach that has the potential to better protect a pitcher’s weak link- the UCL (Part One). While traditional meth...

Bullpens, Tracking Elbow Torque, and mStress

This article builds on the previous research that we did with the MotusTHROW Sleeve that looked at the relationship between elbow stress and velocity. Here, we will look at how those relationships have changed (or if they did) under a larger sample and discuss why normalizing stress with velocity is...

Pitching Mechanics: What We Don’t Know

Pitching mechanics are possibly the most hot topic you can talk about in baseball. They are often simplified, for a number of reasons, down to a degree where they can lose meaning. In this series, we’re going to break down some things that affect pitching mechanics and how we approach “teaching” mec...

Analyzing Lower Half Pitching Mechanics Using Force Plates

What We Currently Know About the Lower Half Essentially, nothing. There are studies which have linked lower half force production to ball velocity, and other studies which show very little correlation between the two. One study noted particularly strong correlations between force production and wris...

Does Arm Speed in Pitchers Matter?

A common criticism of training using overload/underload implements is that training using weighted balls only trains arm speed, and that such a training method either: Increases the chance of an arm-related injury Doesn’t improve velocity as arm speed is similar across all ages despite differi...
