Veteran  351  |  Subject: calculating calories burned swimmingAnyone have a good way to do this? I use a HRM when I do anything else, but it doesn't work in the water. I know calories burned is a very individual thing, but I have no clue where to even start figuring out how many calories I'm burning. Thanks! |

Not a Coach 11473   Media, PA | Subject: RE: calculating calories burned swimming Guesstimating about 500 cal/hr is probably a reasonable place to start. From what I've seen, HRMs are little better than guesstimates anyway. |

This is inline with what I have read; the rate that is often used 100Cal/400m. Shane |

Champion 10018 , Minnesota Bronze member | Subject: RE: calculating calories burned swimming That seems kind of unrealistic, simply based on the fact that it takes a poor swimmer an entirely different amount of time and effort (more) to cover the distance than a good swimmer. I am always skeptical of distance based calorie burns... Just something to consider. |

I am always skeptical of distance based calorie burns... Just something to consider. It's a realistic average or starting point, not exact. Also, this could be one of those "run 5 miles in X amount of time and burn X calories" or "walk 5 miles and burn the same calories over a longer period of time." |

Champion 7233 | Subject: RE: calculating calories burned swimming not sure if its the same as running, but if so, its simply a matter of the faster runner is doing more work, less time, the slower runner is doing less work, more time. |

Master 1531 TORONTO | Subject: RE: calculating calories burned swimming I'm always skeptical of those online calculators or what my Garmin says. I've gone for bike rides where it says I burn 700 in an hour!!?? I work off the assumption I burn 100cal/10 minutes while running and 75cal/10min while cycling and swimming. That would put me at burning 450/hr which is sort of inline with what others said above. It's completely unscientific but I figure I'd rather be lower than higher. |

Thanks! are you wondering so you can track clalories for weight loss/gain or just curious?? yes, for weight loss. I do a lot of calorie counting. From everything I've heard, the healthiest way to lose weight is to have a 350-500 calorie/day deficiency. I usually take my BMR + calories burned - 500 to determine my ideal calorie intake for the day. I shoot to be within 100 from my formula (since I know some are rounded on the burned and eaten side - although after 2.5 years of calorie counting, I've got it down fairly well) |

I"ve worn different HR monitors while swimming and have tried different things,, I usually go with 400 cal per hour to err on the safe {aka skinnier} side of things |

I find this link interesting: http://www.nutristrategy.com/activitylist4.htm to an extent that is not correct. cycling cal burned is a pretty exact science. watts put out over a period of time will give you exactly what was burned. from watts you get kj, from there you have your cal burned. it takes 4 kj to burn 1 cal, but aerobic training of that kind is only approx 25% efficiant, so each kj = approx 1 cal. now, if the OP or the one asking is a bigger person, that kind of power output is possible. however, for a smaller person that would be COOKING fast. as an example, IIRC, 220 watts per hour comes out to 650 cal per hour (migiht have the numbers off a bit). but for most people holding that is moving pretty fast. at my normal zn2 levels i am at 500-550 an hour (this puts me over 20mph). |

Pro 4608 Brooklyn, NY | Subject: RE: calculating calories burned swimming I think it's hard to guess, you really need HR to know. I swam hard (for me) for 30 minutes tonight and burned 280 calories. I did an easy swim on July 4th that took 1:12 and only burned 453. The higher my HR, the more I burn. But it's nowhere even close to 700/hour, that's more like the effort of running. |

Veteran 351 | Subject: RE: calculating calories burned swimming I tried fitday.com - I wasn't a big fan. OK - I like going with distance rather than time ('cause I take stopping breaks, which lengthens my time, but not distance) and since I'm lazy, I need to break it down to 100 yards, So I came up with 23 calories/100 yards (using 250 cal/1k). That sounds like a good estimate to me... |

Champion 7595 Columbia, South Carolina | Subject: RE: calculating calories burned swimming I can't point to solid evidence for this, but here's my reaction: Swimming differs a lot from running -- one can give fairly reliable general formulas for running. Cycling calories are harder to determine (unless you have a power meter), because conditions (wind, hills, weight) matter somewhat more. Swimming calories are even harder to predict, because efficiency in the water matters so much, and varies so much from expert to poor swimmers, and even for a given swimmer, pace matters more because of the significant resistance of water (goes up as the square of velocity, and unlike in running, overcoming the resistance of the medium is the main work you are doing in swimming). |

Veteran 215 | Subject: RE: calculating calories burned swimming Funny I was thinking about this today while I was in the water. I wore a BodyBugg for two years and so have an approximate idea of what I burn lifting weights, in a spin class, etc. Can't wear a BB in the water. The most I ever burned in a 50 min. high intensity spin class was about 375 calories. The most calories I ever burned in a day during the two years wearing the Bugg was 2700 when I had an intense workout followed by grocery shopping. My average daily burn rate was around 1600-1700 calories. Probably 1800 now. Knowing my history, I'm not going to figure I burn more than 100-150 calories during 30 mins. of running or swimming, and less biking. I think I'm pretty close because my nutrition hasn't changed much and I haven't lost more than a pound since I added in the tri training. |

Expert 1073 scottsdale, az | Subject: RE: calculating calories burned swimming I don't believe calculators. I had a similar spin experience. I think I burned around 350 calories for one hour and I usually burn 450-500 on a EASY run?? Spin class is TOUGH, I'm usually sweating buckets! |

Champion 7233 | Subject: RE: calculating calories burned swimming HR is also not a terrible great way to calculate cal burned....... I can go ride at 200 watts and have my HR be at maybe 140, while another rider would be shooting sky high, and a TDF level person would be at like 90. guess what, in an hour at that pace we all burned the same amount. most calculators/HRM dont look at that, or they have very very skewed systems to figure it out. |

Veteran 215 | Subject: RE: calculating calories burned swimming I know a device like a BodyBugg is not 100% accurate, but after wearing it for two years and logging my nutrition, weighing all food in grams, I found by tracking calories in and recording actual weight loss that the BB can be pretty close. To account for inconsistencies I always left a margin of error of 100 calories under on calorie burn on 100 cals over on calories consumed, to give me a buffer when I was shooting for a deficit. I know several people who have used both HRM and the BB and find that the HRM usually over estimates by quite a bit. For me, 375 is the most calories my BB ever showed me burning doing any one activity...and spin class is hard...so that made sense to me. |

Champion 7233 | Subject: RE: calculating calories burned swimming not needing details here, but how big of a person are you? 375 for an hour of that seems low unless you are tiny. i am not a huge person, 150 or so, but i know i would have to be almost sitting still to only burn 375 on the bike for an hour. |

I find this link interesting: http://www.nutristrategy.com/activitylist4.htm This validates what I am saying. At 200 pounds, to ride at 19 MPH for 1 hour I MUST generate more watts than the 150 pound person, thus burning more calories. It takes more power to move the added mass. At the same pace the 150 pounder and 200 pounder absolutely will not burn the same calories, because our power output has to be different. I am not claiming to be an expert but this just makes sense. Bigger "vehicles" require more fuel and more power to do the same amount of work. |

I know this is all individual and subjective, but in a 50 min high intensity spin class, I usually burn around 750 cal!!! (and that's if you trust my HRM) Stupid question, but I still don't understand any other way to measure calories burned than with a heart-rate monitor. So, since a lot of you seem to think they are not accurate, how do you measure? |
