Sources for science of masters swimming?

I am about to start researching an article on masters swimming, including its various physical and psychological benefits. I am wondering if any of my fellow swimmers know of exercise physiologists, sports psychologists, cardiovascular investigators, swimming scientists, etc. who may have looked at the specific benefits of masters swimming. So far, researchers I am hoping to interview include: Dr. Steven Blair, leader author of a recent study on swimming and longevity/risk of premature demise Dr. Dave Costill,legendary emeritus director of the Ball State human performance lab and a great masters swimmer in his own right www.usms.org/.../toptenind.php Dr. Joel Stager, another exercise physiologist and great swimmer (I think in my age group, actually) who was the fellow who found that chocolate milk is a great way to renourish yourself right after a workout www.usms.org/.../toptenind.php Phil Whitten, another legend in the masters community who did some work years ago at performance declines with age (and how you can avoid or dramatically slow them) www.usms.org/.../toptenind.php Aimee Kimball, Ph.D., a sports psychologist here at UPMC in Pittsburgh I am looking for, among other things, someone who has looked at the effect of adult swimming on: mood and emotional regulation cognition, cardio health strength, endurance, joint flexibility/range of motion injury rates and time sidelined in swimming vs. pavement pounding land sports the reinforcement aspects, and social camaraderie, of team membership (let's face it, there are very few sports you can be on a team as an adult); finally, something very specifically on competition, which in some circles is a bit maligned these days, but seems to me a very powerful motivator for lots of masters swimmers to keep going. Thanks for your help! I may post this on the threads, as well, in the hopes of getting some suggested sources. If you know anybody that might fit any of these bills, or if you have any research associates/friends who might know somebody, please pass on your suggestions. My email address: jamesthornton1@comcast.net PS if you happen to be a guy in the Men's Health demographics, i.e., somewhere between 18 and your 40s, and you have found masters swimming to have been a life-changing and/or life-enriching experience, please drop me a line! I need guys who swam in their younger years and have come back to it; I also need guys who perhaps never swam competitively (or at all) and came to the sport as complete rookies in adulthood. Thanks!
