Long Q Interval Any swimmer's out there who have this?

You paid for the test. It is absolutely your right to get a copy. If they get prissy about emailing it, ask them to put a copy in an envelope and arrange to go pick it up. I doubt they will get prissy, but if they do, they don't have any legal right to keep it from you. There are reasons to suspect that water exercise is different from land exercise. When that Stephen Blair study came out a few years ago, showing that swimmers had greater longevity than runners, even though swimmers were not as lean as the runners, he told me that he thought this was a fluke of relatively small portion of swimmers compared to runners in his data base (from the Cooper Center for Aerobics Research). He did acknowledge, however, that swimming places different physiological demands on the body. Gravity does not impact swimmers as much, the body is in a horizontal rather than upright position, and moderate temperature water is much more suitable to cooling muscle heat than even cold air. There is also the mammalian dive reflex, which Wikipedia describes thusly: The mammalian diving reflex is a reflex in mammals which optimizes respiration to allow staying underwater for extended periods of time. It is exhibited strongly in aquatic mammals (seals, otters, dolphins, etc.), but exists in a weaker version in other mammals, including humans. Diving birds, such as penguins, have a similar diving reflex. Every animal's diving reflex is triggered specifically by cold water contacting the face – water that is warmer than 21 °C (70 °F) does not cause the reflex, and neither does submersion of body parts other than the face. Also, the reflex is always exhibited more dramatically, and thus can grant longer survival, in young individuals. The first step in the reflex: Bradycardia is the first response to submersion. Immediately upon facial contact with cold water, the human heart rate slows down ten to twenty-five percent. Seals experience changes that are even more dramatic, going from about 125 beats per minute to as low as 10 on an extended dive. Slowing the heart rate lessens the need for bloodstream oxygen, leaving more to be used by other organs. Again, I am just an armchair speculator here, but it would seem to me that if cold water on the face is capable of inducing dramatic plummets in heart rate, it must be impacting the heart's electrical system is some way. Perhaps those with Long Q have an electrical system that is already, in some sense, cranky--and this additional insult can be enough to tip it over the edge? It would be interesting to see how much more common sudden drownings are in colder water. Another world class researcher in your neck of the woods is a very nice guy at U Indiana, Dr. Joel Stager. He is a masters swimmer himself and an exercise physiologist (and parenthetically the guy who became famous for finding that chocolate milk is an ideal post workout recovery drink:(1) Karp, Jason R.; Johnston, Jeanne D.; Tecklenburg, Sandy; Mickleborough, Tim; Fly, Alyce; Stager, Joel M (2004). The Efficacy of Chocolate Milk as a Recovery Aid. Medicine & Science in Sports & Exercise. 36(5) Supplement:S126.) Perhaps if you run into him at a meet in the future, you could ask him if he knows Gull's referral, Dr. Douglas Zipes. The combination of a cardiology researcher with expertise on a condition known to be particularly risky to swimmers, and an exercise physiologist and director of U. Indiana's Counsilman Center for the Science of Swimming, could make for a fascinating double-barreled study of this condition. Hmmm, great idea Jimby! I am a friend of Dr. Zipes daughter-in-law, I used to teach with her. She told me he's not accepting new patients. I just finished goggling him and according to his site on Krannert Center he is. I have met Joel Stager a couple times at the IU meet. He's a nice person. I participated in his study at Nationals in Indy a couple years ago. I wonder if he still has my records? I'll e-mail him tomorrow.
