Is 560 Cal the same number as you get if you input "walk"? It may be a standard activity number. (I'm too lazy to check it myself, sorry.)
Now for a real geek comment: Since during scuba you know the max amount of Oxygen you are consuming (cannot consume more than what you carry in your tank), you can probably get a good estimate of energy displacement that way.
Is HR really proportional to energy displacement? I keep reading that sex is not a good weight loss exercise yet my HR goes really high just thinking about it. I can also start counting meetings with my boss as exercise. ;)
Hi thanks for the feedback. I've heard there are HRMs that are waterproof up to 30 meters. Actually I'm just curious how many calories I burn when scuba diving. The fitness tracker on Spark People, shows I burn 560 calories per 80 minutes (about 2 dives), and that's A LOT!. I mean, doesnt it matter wethear you're going against the current or at a relaxed pace.? The tracker just has "Scuba diving" for the activity that's all.
I want to get a HRM anyway so I know how many calories I really burn during any exercise, so I was thinking if I'm going to get one I should get one suitable for water activities.
