Weclome Garydemo and Instagator!!!
Garydemo- I'm a runner too, but not up to the numbers you post.. someday.. someday...
(I can be a bit blunt so forgive me).. your DM is full of himself. Let's put this in another view. As a runner, are you a more efficient runner being fit or unfit? I know, stupid question.. but ANY exercise that you are more fit, you are a better conserver of energy and the oxygen exchange that happens during a breath is more efficient. Scuba is no different. As a fit person you are more efficient underwater. The fact that you are a new diver, for now, pretty much negates all that. Sorry. Once you get more comfortable in the water, get your buoyancy control figured out and become streamlined, your air consumption will drop dramatically. Maybe Coach Izzy can explain it better, he's the fitness guru here.
Gary, glad you are starting the C25K program!!! Awesoome!!
Beautifully put together Jenny! One of the things I remind fitness trainers whenever I lead education workshops is how lately a little bit of information mixed with a lot of speculation and spiced by imagination are being passed as facts. What the DM said is the perfect example.
Garydemo, as Jenny was saying, gas consumption in scuba diving -provided there are no unforeseen circumstances- is a function of skill and experience rather than physical fitness. That's why even folks who are not physically fit can manage the activity... until things go awry.
Fitness is of tremendous importance for environmental transitions and managing emergency situations, that's why we need to be physically fit, and in my super-biased opinion, fitter than any other aquatic sports. A physically fit body also increases our confidence, which allows us to relax more in the dive, thus improving our gas consumption.
I would recommend adding strength training and alternating running with other activities to avoid overuse injuries. Best to you!
