This site has a blog , propulsion theory formulas, abstracts with math formulas; (yawn), and lots of training information with graphics and charts. Best of all is a video of Inge de Bruijn: [Link]I got the link from About.com. You can have them send you swim updates if you want, but for now Here is their synopsis:
"... The object of study of the Swimming Research Center Amsterdam is competitive swimming and how to improve a competitive swimmer.What aspects determine performance in swimming? How does the swimmer adapt to training?How is propulsion generated? Can drag be influenced by technique?What is the optimal training program? Rather than looking at any of these aspects separately, the major mission of the Swimming Research Center Amsterdam is to reveal the relationships between metabolic, morphological, mechanical and coordinative aspects of swimming. ..."
