>Dear Dan: >Please let us know if you have any important announcements > for our Calender of events pertaining to the diving >community. >Regards >Jorge Giraldez-Benard >Sea Frontiers Magazine > Hello Jorge, One of our more exciting events is the Doppler workshop Nov 4,5 which is significant to me for the following reason: I believe present deco theory and tables are OK for average divers, but they fail miserably for those who are in a bad state of fitness or in very good fitness.....the idea of aerobic condition and its relevance to gas exchange will have large effects on diver safety. A sedentary person with a poor VO2 max (ability to transfer O2 throughout body) will have a safe single dive inside the limits of no stop diving, but should this same person do multiple dives, their ability to offgas will not keep pace with the model predictions. Conversely, an elite competitive athlete like a cyclist would be less safe on a 60 for 60 than the overweight diver with poor VO2 max, because the athlete would absorb far more N2 through much better gas exchange. With a stop added to both divers on this same profile, the athlete would rid himself/herself of N2 at a much faster pace, and after significant deco time would be cleaner for repetitive dives. To the tech community where deco stops are mandatory, personal gas exchange rates could offer an enormous advantage to diver safety, and could be computed using information gathered from a correlation between a VO2 max test (simple test with heart rate monitor) and the doppler studies Dave Schubert will be conducting at Dive USA in November. With a large enough database of elite athletes, normals, and physically challenged couch potato types, we may be able to create some sweeping changes to current practices! > > > Look us up at >http://www.rsmas.miami.edu/sea-frontiers/sea-frontiers.html >or send us your address and we will mail you off a couple >of copies. >Regards >Jorge Giraldez-Benard >Sea Frontiers Magazine I really like your magazine...please send me some issues!
