Pitching Biomechanics: Front Foot Landing Can Make Difference!


A pitcher’s foot position at foot strike can provide a solid foundation to facilitate both knee extension and efficient transfer of energy. Foot strike is the moment a pitcher’s front foot makes contact with the ground and is the starting point of energy transfer up the kinetic chain. This energy is ultimately transferred to the ball at release, with efficient energy transfer being aided by the pitcher releasing over a firm front side. A firm front side provides lower body stability for proper upper body positioning through release. This stability is achieved by extending the front knee from foot strike to release and is why knee extension angular velocity at release is correlated with pitching velocity and an important metric to examine in pitchers.

Pitching Biomechanics: 3 Factors in Kinematic Sequence

Pitching biomechanics

In conducting a pitching biomechanics evaluation and assessing a motion capture session, one of the most important things to examine is the kinematic sequence. This consists of the angular velocities and corresponding timing of the pelvis, torso, shoulder, and hand. These angular velocities can reach speeds upwards of 5000 º/s, and as such cannot be measured through standard 2-D video analysis thus requiring a 3-D motion capture system. This simple graph below off our Qualisys Motion Capture system is key to determining how efficiently an athlete is transferring energy from the ground up, through their body, and into the ball.

A Pitching Biomechanical Evaluation to Create Better Fixes

By Nunzio Signore (Owner/Operator RPP)

Pitching is a MOVEMENT and should be analyzed as such. In a pitching biomechanical evaluation such as a mocap assessment that we use here at RPP, there are many important metrics.  Specifically there are timing and angular velocity issues that you can’t see with the same amount of accuracy when using a static assessment or 2D video analysis.  Knowing WHEN these movements are happening at various points in the delivery, and for certain metrics the SPEEDS at which they are happening, can be more telling than simply looking at static positions.

But, the value of the information, like every other piece of tech we utilize, is not in the numbers, but what we do with the information, in other words… the FIXES. This is where blending tech with great coaching can be a game changer. Continue reading “A Pitching Biomechanical Evaluation to Create Better Fixes”

Why Baseball Biomechanics Information is a Game Changer

baseball biomechanics

Until not long ago baseball biomechanics information from motion capture systems (mocap) was primarily available in research labs, rehab facilities or biomechanics departments at universities.  Much of the work in this arena has been performed by biomechanists who specialize in the study of movement. They generally use the principles of physical mechanics combined with biology to understand:

    • How we move
    • How we can move more effectively and efficiently
    • Why we get injured and how to reduce the incidence of injury

Two prominent figures in the world of baseball mocap have been Dr. Glenn Fleisig and Dr. James Andrews, dating back to 1985 with their work at the American Sports Medicine Institute (“ASMI”).

But times are changing fast… Continue reading “Why Baseball Biomechanics Information is a Game Changer”
