so the study does not compare the two for what makes you stronger or bigger.. merely compares how to train better for negative impacts .. I.E. what muscle science said in the link posted, people such as ski jumpers, basketball players
Concentric training
increased concentric (36%, P < 0.05), isometric (18%, P < 0.05), and eccentric strength (13%), and
eccentric training
increased eccentric (42%, P < 0.05), isometric (30%, P < 0.05), and concentric (13%) strength. Eccentric training improved eccentric and isometric strength more
I would like to point out that this in some ways proves my point, because every bodies goal is to do a contraction, so if eccentric training only has a 13% effect on contraction. but concentric training has a 36% effect on contraction... and of course eccentric training will help eccentric strength. but who's goal on here is to have a strong negative?
the study only shows that women's quad muscles have more eccentric strength and isometric strength if they train eccentric.... which sums up to say if you want a stronger negative you have to train with negatives. or isometric (which means the muscle holds a weight in one place no lowering or raising)...
since we don't know the base line of the women, all we can say is that women gain strength on negatives for negatives faster.. which proves nothing in the form of long term strength or muscle size. because the study had nothing to do with anything except finding the best way to improve a negative or the ability to hold weight (isometric)...

this is my last post, this is going to be a topic people can debate for years and it still comes down to do what you do, and if it works than great...
