Early Trunk Rotation and Losses in Pitching Velocity

early trunk rotation

While performing hundreds of video analysis and mocaps yearly, “early trunk rotation” rears its ugly heads more than 90% of any other disconnect we see. An early trunk puts the upper body in a more compromised position to accept ground reaction force and effectively block with the lead leg while negatively affecting timing issues and transfer of force up the chain. It can also contribute to a late arm or an arm that “drags”.  All this, of course, can ultimately lead to losses in pitching velocity.  The key is finding what is causing this early rotation, training it and putting the arm in its “sweet spot”.

Pitching Biomechanics: Hip Shoulder Separation, Closing the Gap

hip and shoulder

We have talked in the past about hip-shoulder separation and its importance in the pitching motion. In this article, we will dive deeper into the idea of “closing the gap” after max separation has occurred. More specifically:

    • When does it occur (timing)
    • How quickly does it close (explosiveness)
    • How completely does it close

We will also review some potential issues and how we may address them.

What are the Most Common Pitch Movement Issues… And the Fixes

pitch movement

Having observed hundreds of pitchers on our Rapsodo Pitching camera during the past several years, it’s fair to say that there are a few tendencies that most high school and collegiate pitchers exhibit. While every pitcher is different with their skillset, we generally tend to observe similar opportunities for improvement in pitch movement.

In this first of three articles… Continue reading “What are the Most Common Pitch Movement Issues… And the Fixes”

How to Build a Baseball Throwing Program

baseball throwing program

Over the past few years, we have had hundreds of baseball players, specifically pitchers come through our facility. While they come in all shapes, sizes and technical ability, they all are looking to do the same thing, how to throw a baseball harder and do so safely working with a baseball throwing program.  So, while this article is about how we build throwing programs, it’s important to highlight that the body has its own language and agenda, and you cannot learn it by only learning 3 or 4 words.  You certainly can’t do it by slapping together some throwing drills with long toss and pull-down days.

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.

Putting on the Brakes to Throw Gas… What is Lead Leg Block?

lead leg block

The lead leg block is the act of slowing down your body’s momentum with your lead leg at landing. In biomechanics, deceleration and the lead leg block can be represented by peak changes in angular velocity. Think about your car. The gas pedal represents your drive leg at the start of the pitching delivery (power output) and the brakes represent your lead leg’s role at foot contact (power absorption and transfer of force).  Let’s cover this in three parts:

    • Why is it Important to be Good at Decelerating?
    • What We Look For?
    • How We Address Lead Leg Block Issues?
