Sevas - post your anti pro running crap on that thread you devoted to it, it has nothing to do with this thread. We’re all tired of your rants, that’s why those threads died out. Please don’t change the direction of this thread.
This is a totally different topic and having read that someone gives a very young kid a session of 15 x 200’s as part of a sprint prep I felt concerned enough to comment. In my view, it is tantamount to child abuse. It serves no purpose and would not help their sprints one iota. I doubt the kid will be around in 12 months if that’s typical of the training he gets.
btw, The training effect on VERY YOUNG kids doing sessions like 15 x 200’s is light years away from the training effect on mature aged athletes.
