Does excessive hyperventilation before endurance training(in a pool) lead to shallow water blackout? While training lately, my arms, legs, and fingers go numb while surfacing from the bottom of the pool to the point of almost passing out. The pool is only 12ft deep. A local commercial diver training there noticed my symptoms and told me about swb. It seems many divers die while diving only at 10 to 15 feet. Is this a physical problem that can be overcome with training or am I doomed to a landlubbers existance?

Hyperventilation...increases the risk of blackout and should not be done when training andurance in pool. SWB, is quite a different thing.......
Here is just one thread that deals with that issue..and ther eis much more around here for you to read and learn from..

on forums and on articles as well...
and one last thing stop hyperventilating when you do your pool training!!! We don't want to lose any freedivers because of that!!!
