Eh, I don't think so -- dilated capillaries and increased blood turnover are the good part of exercise. The problem is more likely shear at large joints (cavitation) and agitation (shaking the fizz). Still, the whole issue may be exaggerated since there's plenty of turbulence in a living body in the first place. No turbulence means you're dead, which tends to be an undesirable condition for a decompressing diver. Light work at deco is actually good since it ensures ample perfusion of all tissues. Weight lifting may be bad after a dive but a little horseplay and finning at deco are certainly superior to a stagnant hang. Movement is good -- strenuous excercise may be bad. What I'm saying is, don't put too much emphasis on the "fizzing soda pop" theory. It's always nice to have somebody else pull the anchor but please stay active after a dive. regards, Hans --=====================_3262616==_.ALT Content-Type: text/html; charset="us-ascii" <html> At 12:28 AM 1/11/00 +0200, you wrote:<br> <font size=2><blockquote type=cite cite>>Recently I had a discussion about exercise after diving, with one of my dive<br> >buddies.
