According to fitday, my hour and a half of swimming (half breaststroke and half backstroke) adds up to 732 calories. That seems like kind of a lot. I know fitday is notoriously inaccurate in estimating basal calorie needs, but are they roughly accurate with respect to calories burned during exercise? BRBR Do you know how far and fast you are swimming? Your speed counts. If you know the length of the pool and how many lengths equal a mile, you can figure out how fast you are going. I could but I'll probably go with a close enough for government work guesstimate. A few years ago, I found two charts that give the calorie expenditures for swimming, by body weight. The websites are gone, but here's the info I copied from them. Website 1 gives calories for two speeds: 25 yds per minute and 50 yds per minute. Counts are for a 30 minute swim. It has values for body weight ranging from 90 lbs. to 300 lbs, but I'll give you the info for a 150 lb swimmer: A 150 lb person swimming 25 yds/minute burns 180 calories per 30 minutes. A 150 lb person swimming 50 yds/minute burns 338 calories per 30 minutes. The second website says: A 127-137 lb. person swimming 20 yds/minute burns 4.5 calories/minute = 135 calories per 30 minutes A 127-137 lb. person swimming 55 yds/minute burns 12.5 calories/minute = 375 calories per 30 minutes A 160-170 lb. person swimming 20 yds/minute burns 5.3 calories per minute = 159 calories per 30 minutes A 160-170 lb. person swimming 55 yds/minute burns 14.8 calories per minute = 444 calories per 30 minutes That's what the charts say, but who knows? These numbers seem to be similar to the Fitday number. Hope this helps you. Thas is hugely helpful thanks. I don't need to figure out the exact rates, since I'm not trying to exactly balance my food v. my energy expenditure, but seeing the ball park numbers definitely motivates me to add the extra half hour or so when otherwise I might figure I'd done enough for the night.

I know fitday is notoriously inaccurate in estimating basal calorie needs, but are they roughly accurate with respect to calories burned during exercise? If it's true, damn but I wish I'd bought in a building with an indoor pool, 'cause I can swim forever (I only ended yesterday 'cause I was bored and had to pee). In addition to the exercise, water conducts heat from the body 20-25x faster than air, so your basal rate goes through the roof - I imagine this is included in the Fitday calculation. I spent 5 hours Saturday and 8 hours Sunday in a pool doing scuba Whoa, you must have had some serious finger prunage going on. certification - Fitday quotes it as ~3000 and 5000 calories. First time I've ever felt hungry on Atkins - a quick stop at Outback fixed that (14 oz. ribeye w/bleu cheese, cup of broccoli, Caesar salad w/out croutons, Shrimp on the Barbie!). (Is it me, or does "Shrimp on the Barbie" bring up thoughts of sushi girls?) It's just you. g Martha -- "Only those who risk going too far can possibly find out how far one can go." -- T.S. Eliot |

Thas is hugely helpful thanks. I don't need to figure out the exact rates,
since I'm not trying to exactly balance my food v. my energy expenditure, but seeing the ball park numbers definitely motivates me to add the extra half hour or so when otherwise I might figure I'd done enough for the night. Thanks, Martha BRBR You're welcome. I did all the figures for myself a few years ago. I was swimming 1 1/2 hours a day and it came out to be around 750 calories per swim. I was impressed with myself, but then actually gained weight because I was hungry all the time and didn't control it since I thought I was burning so much. Buyer beware. |

Fortunately I only added a few pounds, but it's amazing how easy it is to rationlize having a little something for dessert when you feel like you've "earned" it.
