What's Inside

In this course we review the metrics that we use in our biomechanics report. These are common 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

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.
