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...

How Muscles Work to Protect a Pitcher

Let’s talk about muscles. Muscles are the motors of the body. They are the components that generate movement. They can also absorb dangerous forces to protect more vulnerable tissues, like ligaments, and this is especially important for baseball pitchers. Before I dive in, if you missed part one or...

Challenges with Typical Biomechanical Analyses of Pitching

This is a guest post from Dr. James H. Buffi, Ph.D. in Biomedical Engineering. It is impossible to overstate how excited I am to have Dr. Buffi contribute to our blog in what will be the first article in a three-part series on the biomechanics of pitching. In 2014, Dr. Buffi had a paper published ti...

Releasing Tommy John’s Grip on Pitchers

It’s about that time, isn’t it? The short period of time where we notice the rash of Tommy John surgeries and shoulder injuries to pitchers and look for answers in the usual places, like Tom Verducci’s columns (never mind that the Verducci Effect has been thoroughly debunked) where...

Is the Coach Responsible for a Pitcher’s Arm Injury?

I’ve often said in the past that elbow injuries (specifically UCL tears) are due to microscopic fraying of the ligament due to a variety of factors – poor mechanics, improper warm-up, poor fitness, etc –  that eventually cause a partial or full rupture of the ligament, thereby dest...

How Wrist Weights Reduce Your Tommy John Risk

Longtime readers of this blog know that I am obsessed with technical and anatomical precision – and in many cases, the message can be lost upon your average reader. However, I try to summarize all of my jargon into an immediately understandable conclusion at the end of long articles like Elbow...

How to Analyze Pitching Mechanics Without a Biomechanics Lab

There are a few writers and people out there who criticize me for talking about pitchers’ mechanics without having specific joint loads (kinetics), stating that it’s akin to “guessing” without any merit. Their claims that without a full biomechanical analysis (presumably usin...

Young Arms and Curveballs: The Real Story Behind it All

Two weeks ago, the NY Times published an article titled Young Arms and Curveballs: A Scientific Twist. In the article, Bill Pennington interviewed various experts in the field of youth baseball pitching and got mixed answers. Dr. Fleisig of ASMI said his research can’t prove that curveballs ar...
