Fatty tanks of Nitrox!

[ggunn]

Oh, I am sure I could find plenty. You didn't know?

I doubt that my searching would be rewarding. It's been covered in the medical forums.

Seriously? Not just exercise in general, but specifically climbing the ladder with gear on?

No, any exercise. Climbing the ladder with gear is strenuous.

As far as nitrox being a waste on Cozumel, I agree that with 2 dives/day given the typical multi-level profiles, it's not worth the extra cost, at least to me. But, if I were doing 4 dives/day I'd use it.

Well I would have to cut my BT or buy a more liberal computer than my Mares or dive with an OP that time limits you. No way I could do my current typical profile on air.

On my last trip, 3 out of 8 days I only used 1 tank of nitrox (EAN36) for the first dive and air for the second (simple reason, I was being cheap), all were AL80's. Using an Oceanic on DSAT I was forced up and out on the second dive mid way through, repeatedly if on air. So yea, EAN for me is not optional if I wish to maintain BT.

Studies have shown a correlation between strenuous exercise after diving with increased risk of DCS but I don't think getting back onto the boat is what they are talking about. In fact, light exercise decreases the risk. Climbing a ladder is not considered heavy exercise. It may be difficult for the old and weak but just as some find getting out of bed difficult, that doesn't make it heavy exercise within the context of this issue.

What's this?
Exercise Before, During, and After Diving

Light aerobic activities, like walking and swimming, mildly increase heart rate and redirect blood from organs to muscle and associated tissues. Before a dive, such exercise will not affect nitrogen uptake. After a dive, it would be expected to promote safe offgassing and inhibit bubble formation and expansion. In fact, some studies suggest light exercise decreases the incidence of DCS.

However, vigorous aerobic exercise, like hard running or strenuous hiking, produces pronounced changes. Markedly increased temperature, blood flow, and oxygen use within tissues immediately before a dive could result in an undesirably rapid uptake of nitrogen upon descent. After a dive, such exercise or an exhausting surface swim to the boat could contribute to a dangerously accelerated elimination rate.

I always try to do some light weight lifting after diving. About 12 oz, alternating arms....

Pretty much what I thought; thanks.
