Fascinating, I was always under the impression that the foot strikes directly under the body. People seem to get pissed when mentioning that you pull a bit with the hamstring on the internet.
Chris, would you be able to describe to me what you do for the Transverse Abdominus during RPR? Would love to add that to what we do! Love your work, Took RPR level 1 with you in Portage Indiana in 2018 and have never looked back!
That research highlighting vertical force has always felt odd. Just doesn’t square with what the foot is doing. Great video again. You rate the yuri type stuff? Seems like it’d be easier to do with a sled or 1080 tbh
it was more of a correlational byproduct i think. it was (is?) hard to measure horizontal force so the vertical force was an interesting piece of data that they could collect. I think I read somewhere though that elite sprinters have a higher % horizontal:vertical ratio, but since their overall force is higher so is their vertical force.

man, that ankle-foot complex even comes in at top end mechanics..very intriguing
Great stuff
Incredible insight, wow!

Great video. Interesting on the contribution of the Vastus Lateralis . I would have thought more contribution from Glute Max?
You’re Brilliant!

Same here! Peter Weyand pointed out his observations from the SMU studies but I don't think his explanation was a applicable to sprinting
