Pose claims that there should be no VOLUNTARY push-off. There is sort of a "push off" that is generated by ground reaction force and muscle recoil. This is what is enough to regain the lost height.


So, in terms of the four statements I listed, would your answers be true/agree to each? I'm not sure.

You see, here is where we get into trouble. You state that there is "sort of" a push-off. What is "sort of" if not a vague, imprecise modifier? It leaves much to the imagination, ambiguity arises, and we cannot discuss the matter with accuracy. Second, please define what you mean by a "voluntary" push-off. Am I to take this as the leg muscles do not contract under the control of the runner (for example, "voluntary" meaning the sort of control one would apply to leap vertically from a standstill)? Third, although I take it that "muscle recoil" refers to the stored energy of landing, I am not sure what you mean by "ground reaction force". Landing on the ground causes the reaction of storing energy in the legs, but as you have already included that item (aka, muscle recoil) I must assume you are referring to something else (or you're being redundant).

The more precise we are, the fewer misinterpretations there will be.
