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?

How to Increase Athleticism… Develop Efficient Movement

On any given day you can log into your daily feed on Twitter and scroll through a plethora of verbal grudge matches between strength coaches, pitching/hitting coaches and movement gurus arguing.  Yes, arguing and criticizing each other’s ideology about athletic performance and how to improve it. These verbal assaults are usually fueled by the fact that one individual’s concept, theory, protocol or whatever you choose to call it may not line up with another’s. In other words, “it’s different”.  For those of you that have the insight to be able to “discuss” and not argue, this blog is not targeting you, however you may want to come along for the ride.

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.

Why the Baseball Spin Axis Is Important for Pitchers

baseball spin axis

The Rapsodo Pitching camera provides an incredible amount of information by pitch type.  Just as relevant, however, is how each individual pitch behaves versus the others.  In evaluating our pitcher’s ball movement charts, we generally work with them to develop what we refer to as “clusters”. They form when a pitcher can consistently repeat the baseball spin axis and direction by pitch type. Continue reading “Why the Baseball Spin Axis Is Important for Pitchers”

A Pitching Biomechanical Evaluation to Create Better Fixes

By Nunzio Signore (Owner/Operator RPP)

pitching biomechanics

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”

What to Ask When Selecting a Pitching Program

A few years ago, all you could expect from your pitching program was to help you with your mechanics. That’s just about what most people expected and looked for in a pitching program. Fortunately, times have changed. Today, pitching mechanics are only a piece of the overall puzzle.  There is much more to training pitchers than simply teaching them proper mechanics.  Whether you’re looking for an off-season pitching or throwing program, here are six questions you can ask pitching coaches and some guidance on what to look for… Continue reading “What to Ask When Selecting a Pitching Program”

What to Do With All the Data Coming Out of Showcases?

During the past year several showcases announced partnerships with technology companies, whereby participants skills are measured during their events.  We’re not talking about the usual 60-yard dash.  We’re talking about esoteric topics like vertical bat angles of a swing and spin efficiency levels on a pitch.  On the one hand this is great news for the game. Technology is changing baseball for the better and the data can be invaluable for both training and evaluation. On the other hand, although I am a big believer in tech and the value it brings, there is an issue. Continue reading “What to Do With All the Data Coming Out of Showcases?”
