Implementing Workload Management with the Driveline Pulse Sensor

After testing and working with Driveline Pulse sensors this past off-season, beginning this summer we decided to fully implement a workload management system for our pitchers. The purpose is to help manage throwing workload in our throwing programs on a year-round basis. Workload is a general term used to describe how much stress is being placed on a pitcher’s arm during both a single throwing session and over a period of time (as in a week or month).

The basic premise is as follows.

A Week in the Life of an RPP Data Intern

I joined RPP Baseball as a Data Intern this past September, and was very excited about the opportunity to learn all of the different aspects of applying technology to training pitchers and hitters. Little did I know how all-encompassing it would be. The process of working and training daily with the latest technology has proved to be an amazing experience for my personal development as a professional in this industry. Whether I am working with Rapsodo Pitching, Rapsodo Insight, Blast Motion, HitTrax, K-Vest, or assisting with our bio-mechanist on a full blown Qualisys motion capture system, I am amazed at the impact that data and technology can have on player progression and talent maximization. I decided to write this article, not only to summarize how much I have learned in this position, but also to help provide a road map for all those that may come after me.

Wondering What Happens to all the Data from Motion Capture?

Today, we’re lifting the hood a tiny bit…. Much is written about the value of data and its potential application to training pitchers. But a full-blown motion capture system takes this type of discussion to a whole new level. A typical mocap session involves attaching over forty markers to a pitcher’s body. After a pitch is thrown off the mound, the system combines the views of a dozen or more cameras to create a 3D avatar of the athlete, which then allows for preparing angular measurements of various body parts, up and down the kinetic chain.  What happens to all that data from the avatar is what we are going to review here…

How Much Scap Load… What is Efficient?

Scap Load

Horizontal shoulder abduction, scap load, elbow angle are terms originally coined by Paul Nyman and which refer to the retraction of the shoulder blade (scap) prior to the arm cocking phase. Call it whatever you like, but the degree to which your scap “loads” matters. Horizontal abduction helps with layback and setting up the rest of the arm action once the lead leg blocks, decelerates and sends energy up the chain. Continue reading “How Much Scap Load… What is Efficient?”

Where Mocap Can Help Fill the Gaps!

Most of you already know that while we are big believers in using data/tech, the human element should never be replaced, just simply “enhanced”. So let me start with this great quote by PT (and super smart guy) Bill Hartman:

Technology provides answers that are stored or calculated. It serves me. It is not creative or curious nor has the capacity to ask the important questions. Those qualities are purely human.

However, as I have said before there is great value to data, especially in areas where you can’t necessarily observe what’s happening during the delivery, but it can be measured.  Today, we’re going to look at an example of the merging of the eyes and data. I decided to write this article after reading a recent thread posted by RPP Pitching Coordinator Justin Friedman. Continue reading “Where Mocap Can Help Fill the Gaps!”

How Can Poor Hip Mobility Impact Arm Health?

hip mobility pitchers

Improving arm health in pitchers is a topic which is typically viewed in reference to the arm itself rather than all the other parts of the body. This way of thinking can potentially lead to arm health issues. When assessing the lower half of a pitcher’s mechanics, often hip mobility issues surface and should be addressed. The purpose of this article is to help provide insight on how we initially assess hip mobility; common issues associated with a lack of hip mobility and ways to improve hip mobility issues. Understanding that fixing poor hip mobility is not an overnight fix is critical in helping the expectations of the progress that can be made if an athlete is consistent in their training.

How to Generate More Power and Velocity with Proteus


To be a more efficient baseball player, it’s important that you have both high amounts of force (power) and acceleration in your throw or in the box. For a pitcher, it can be a deal breaker in terms of college recruiting or ultimately being an MLB prospect. As far as hitters go, having a faster, more powerful swing allows the hitter more time to make better decisions at the plate. While going from 80 to 85 mph may only require more absolute strength, once we get into more elite velocities, max strength is simply not enough. This is where the Proteus machine shines.

Assessing Pitchers in the Age of New Tech (Inside Pitch Magazine)

Interested in a hard copy of the article please click here.

Baseball, like every other industry, is under siege from new technology and it’s making sure the game evolves in many ways.  Some love it, some hate it, and everything in between.  Whether you’re a fan of technology or not, it’s difficult to ignore. It’s here in full force and it’s changing baseball with it.  Those that are too close-minded to take the time to expand their knowledge of the new performance metrics run the risk of being left behind, both in terms of overall knowledge about the game and improving an athlete’s efficiency in performance.
