This is similar to some things I had in my Max Velocity mechanics presentation I was going to give at BSU.
[i]Stable pelvis to maximize elastic enhancements, "big splits", torso angle – height of C of Mass (mid support, toe off)[/i] etc…
Should have known someone was already there, better versed than my limited capabilities.
Might have to use a thesis adviser to protect future projects against unintended plagiarisms?
Still tinkering with a potential response to the Weyland Jedi's…
Just wrote and submitted an article myself about sprint mechanics that covers these topics (and others) in much greater depth. I'll put it on the site before it is published.
