Hey all -
First, some background:
Recently I did my Adv Nitrox and Deco certification (Last August). At one point in the class we calculated our equivalent surface air consumption rate (so we could plan deco dives and estimate how much gas we needed to bring with us). I could be wrong, but I believe we did this by swimming normally at 50 feet for about 5 minutes, then taking before and after pressure readings. We did this 3 times, then took the average of how much PSI I sucked down in the time period. I believe my instructor was about a .4 or less cubic feet per minute.
He was shocked when I came out to be roughly a .8-.9. Now i'm about 6'2 and 240 - am I just destined to be a gas hog the rest of my life? I wasn't finning strenously or working hard against a current or anything.
What can I do to lower my consumption rate? I live in Dallas, so it's hard to get wet regularly. In a good year I probably get 2-3 dive trips in. Usually one or two weekends at Lake Travis and a week somewhere warm.
What non-diving activities can I do to help? I was thinking Yoga? Running? Some sort of cardio program?
Less krispy kremes? ;-) - say screw it and buy a DPV?
Thanks in advance!
