bhouse Posted January 12, 2011 Posted January 12, 2011 I remember a report a few years ago (poss in New Scientist) detailing these free breathe divers - in particular the fact that they had a very low life expectancy (~40?) and considering if this was linked to the adaptations made in order to allow the long dives.

Tubs Posted January 12, 2011 Posted January 12, 2011 I'm not sure of the quality of this article - "This type of freediving - repeatedly diving to depths of 10 to 20m - carries the greatest risk of decompression sickness," says Farrell. "But you are less likely to get the bends if you are lean, or very well hydrated." I'm no expert but I think you need to breath compressed air to get the bends. Tubs Quote
Blatman Posted January 13, 2011 Posted January 13, 2011 "The bends" results from dissolved gasses in the blood returning to their gaseous state as you surface. IIRC, above 20m you do not need to schedule decompression stops, but it's a good idea to breathe out as you surface to relieve pressure inside your lungs, assuming you went down on one breath. If you dive with scuba gear, 20m is still the safe lower limit but obviously you can breathe normally on the way up... I think... How long you've been down at pressure also has a bearing on how much gas may be dissolved in to your blood stream, and how often and for how long you should decompress for on the way up... Quote
peterg Posted January 13, 2011 Posted January 13, 2011 QUOTE but it's a good idea to breathe out as you surface to relieve pressure inside your lungs, assuming you went down on one breath not sure how you'd take any more than one breath if yopu're free diving Quote
peterm135 Posted January 13, 2011 Posted January 13, 2011 You can get bent at any depth on scuba, dependant on many different factors, and sometimes how hard you try ! Free diving shouldn't bend you. Quote
Blatman Posted January 13, 2011 Posted January 13, 2011 Maybe we should ask Jeff C for his input... Quote
Blatman Posted January 13, 2011 Posted January 13, 2011 Not as long as I have a breath in my body Quote
pistonbroke Posted January 13, 2011 Posted January 13, 2011 As a child I once had to hold my breath under water for over 15 mins . Thought I'd never get out of that sack Quote
