[Polorutz]

Hello guys, this question is aimed at all of you super scientist freedivers AHEM *eric* AHEM!!.

I have a polar wristwatch and I know that my particular model doesn't support using it in the water and as I was running and watching my kcal consumption on the watch started wondering how many calories I could burn by swimming and finswimming.

I know Eric uses pulse oxymeters and Spyrometers and whatnot so maybe one of you has determined the kcal consumption per kilometer or per hour? I know it changes with intensity and with the subject but some rough numbers would suffice to ease my thirst for knowledge.

Thanks in advance
