Tempo Workout?

Hey. Can you tell me, it makes sense for the kind bodybuilder training exercise at a rapid pace in which most professional bodybuilders. This Tempe 101, rises rapidly and quickly release the braked dumbbell. He pumped and tired muscles.

It is better to keep a slower pace, like Charles Poliwuin be 302,402? At 8-15 repetitions.
I understand that a quick lifting activate fast-twitch fibers, but why not to run slower the more weight down?
Does someone to train you in this fast paced rapidly up and down?
Thanks for the explanation.
