Frank,
In addition to improved tensile loading eccentric contractions are able to withstand greater forces with less muscular activity. Effectively you are stronger eccentrically than concentrically. This I believe has a lot to do with the parallel elastic component and stored energy within the tissue, but a physiologist would better explain this. I could look it up of course but time is of the essence at present.

Also, some consider a lack of eccentric strength to be a contributor to tendonitis. So, as the muscle builds eccentric strength, it can withstand/absorb the eccentric moments without significant structural breakdown. Isometrics are also good for building tendon resiliency b/c they too provide a high amount of tensile loading.
