How fast should my Speed of Negatives be? - Eccentric Contractions

Quick bit of information:
Concentric Contraction - when your muscles exert force as they shorten (i.e. a curl)
Eccentric Contraction - when your muscles exert force as they lengthen (i.e. straightening your arm) - these exercises are often called negatives.

Which contraction produces more force?
Although we'd imagine the arm can produce more force while shortening, it's actually the eccentric contractions that can produce more force.

Because of this, you've probably heard that you should bring your weights down slowly so you get an extra workout.  The question is, how slowly?  Researchers from the University of Southern California used MRI (Magnetic Resonance Imaging) to monitor muscle firing and found the rapid eccentric contraction of the upper arm activated more than slow eccentric contraction of the upper arm.  Hence, 2 seconds to lockout works your muscles better than 10 seconds to lockout.  More weight faster will work your muscles more than less weight slower.
