Calories Burned Swimming?

snowbab

Hey everyone!

Today i went swimming, and i took my polar F4 HRM to track calories burned. It didn't work though and showed between 0 and 160 :S And it often said I needed to check it because it wasn't working.


I was just wondering how many calories I would have burned so i can log it more accurately? Is there a good, accurate online calculator or anyone who swims a lot who could take a good guess?

Age: 19
Weight: 120
Height: 5'8
Time spent swimming: 1 hour (total swimming time, no resting)

I was doing the crawl stroke practically the whole time, with a bit of breast stroke. I was generally workiong quite hard while doing it. Not extremely vogourous, but I wouldn't say lightly either as I was pushing myself a bit.

Any help is appreciated

Try plugging in into MFP on cardio and you can get a pretty good estimate....not near as close as your HRM but better than nothing.

Yeah it's just I know mfp often really overestimates or overestimates

Online calculators are giving me between 250-700 calories!! :S

MFP says 380-550
