What's Inside

This mini-course has two parts to it.


Part one is 'Pitching Mechanics and Biomechanics.'


In this course, we review the metrics that we use in our biomechanics report. These are standard metrics that you may see in other reports or if you use PitchAI. We review:

  • What each metric measures
  • Common coaching terms that may be used to describe the more technical terms
  • Where our hardest throwers fall in the metrics in our report

It includes chapters on: 

  • Arm Action Kinematic Positions
  • Mid-Section Kinematic Positions
  • Lower Body Kinematic Positions
  • Kinematic Velocities
  • Arm Joint Kinetics

In part 2, 'Basics of Biomechanics,' participants will learn about relevant research in baseball and how they can apply these findings to training and coaching pitchers. 


Key Lessons

  • What are biomechanics?
  • Full signal biomechanical analysis
  • Biomechanics of front leg blocking


By the end of this course, participants will have gained an understanding of how we gather biomechanics data at Driveline, insight into research surrounding biomechanics and workload within baseball, and how these findings can aid in the development of baseball players.

Learn How Energy Flows Through the Delivery

Learn the next level of biomechanics, learning how energy transfer's throughout the delivery. We take a specific look at the lower half and how energy transfer's through the front and bac leg.
