To quote swim guru Bill Boomer, "you swim from your inside, out." I take this to mean that the actual propulsive movements of your limbs are enabled/enhanced by a strong and stable core. There are numerous studies that correlate trunk strength with limb power generation. Ask any of the major college swim coaches if they think they're wasting their time having their swimmers engage in dry land core work. BTW, the study in the news article on rowers seems pretty worthless to me. Consider the source.
