Is this statement true?

No argument there Rich.

My post was meant to elucidate to you and others the considerations one, in my view, absolutely must make when discussing the relation of strength/power exercises to the different phases of a sprint.

I agree; however, your initial question implies otherwise; because if your view of the resistance work is more simplistic, in that it serves a general purpose, I suspect you wouldn’t be concerned with how the exercises you mentioned relate to acceleration or top speed.
