Ok, but at an elite level, which is only my assumption, nothing is random. It is usually the result of training and presumed to be intentional. If that is the path taken by the foot, then why do it? To what end? Also, I am a bit confused as to how the hamstring pulls the foot up…can you elaborate. I assumed there was a pushing motion but the quads and hips were doing a bit of lifting and that point in recovery.
