Not correct. I don’t know about powerlifters but many elite weightlifters incorporate an extensive GPP that consists of sprinting, jumping throwing etc. There are videos on youtube of chinese weightlifters up at 5am to run 100m sprints, do acrobatics etc. Much of the russian literature outlines GPP that would suffice as a sprint program in itself. So if anything, all these drills that the football players are doing should create the optimal conditions to ENHANCE their strength.
This is a BS arguement, the proof is in the world records across every strength sport and strength related sport (Throws). Black athletes are not stronger than white athletes and they certainly do not have a general tendancy to be stronger. /discussion
