@E_Mart97 Good point. You’ve definitely given some things to think about

And I appreciate it! I’m stoked someone is reading my work

Frontal Plane Pelvic Tilt:

Returned back to this project and spent some time looking at both femoral abduction and pelvic tilting in the throw.

Data from @DrivelineBB OpenBiomechanics Project

[Andrew Williamson @AndrewWill01]

First attempt of trying to model the "Hinge" as an attractor state.

Analyzed 294 pitches from 84 unique pitchers.

Rear leg biomech data was analyzed from "Leg Lift" to "Foot Plant" of the lead leg. The time between these moments were normalized.

@E_Mart97 100%

When starting this project, I had a tough time choosing which reference frame to use.

Looking at relative motion would better fit my goals considering that attractors are organized by organism constraints, rather than global orientation.

I’ll definitely look into this!

In relation to this, there isn't much practical insight at the moment. But I was excited to share what I found.

Maybe someone smarter than me can find a way to connect this to application.

[Andrew Williamson @AndrewWill01]

This graph also shows that femoral abduction is steadily accelerating from leg lift to just before peak force.

And that force production doesn't truly begin to build until the pelvis begins returning to neutral.

New blog post about a common question heard in coaching.

"Can you fix my swing?"

It's a short one, but a good one.
