I hope I have understood the articles/references properly…the braking effect talked about occurs when the foot contact is in front of the COM but is not necessarily a matter of design or being deliberate (or at least that would be my assumption).
Does anyone out there intentionally coach sprinters, on occasion, to slow after a run by deliberately trying to “stop”, as opposed to slowing by just slowing the running action down? And is this enough of a load, or too much of a load if from too great a velocity, to have an effect?
I was a bit surprised that the angle of the decline, as seen in the video, 2 percent, was so small.
