Calories burned

Posted Sep 24 2008 11:54am
I'm working on some estimates of calories burned during my typical workouts, to balance my calories in and out a little more accurately.

For a body weight of 172 pounds (let's just use that for a number for now, without further comment) the tables tell me:
  • Run 12 min/mile: 626 cal/hr or 10.4 cal/min (5.5 hours per pound body weight lost)
  • Run 11 min/mile: 704 cal/hr or 11.7 cal/min (4.9 hours per pound body weight lost)
  • Run 10 min/mile: 783 cal/hr or 13.0 cal/min (4.4 hours per pound body weight lost)
  • Swim, hard effort: 783 cal/hr or 13.0 cal/min (4.4 hours per pound body weight lost)
  • Swim, moderate effort: 626 cal/hr or 10.4 cal/min (5.5 hours per pound body weight lost)
  • Bike 15 mph: 783 cal/hr or 13.0 cal/min (4.4 hours per pound body weight lost)
  • Bike 16+ mph: 939 cal/hr or 15.6 cal/min (3.7 hours per pound body weight lost)
Personally, I think those estimates for cycling are on the HIGH side - riding my bike doesn't seem like that much exertion, especially when you compare the heart rates of running vs. cycling. I suspect the tables were made up long ago, long before the advent of efficient, aerodynamic, light-weight tri-bikes.

And jeez, it's a whole lot easier to skip one Death By Chocolate dessert than swim or bike for 2 or 3 hours.

And the real kicker? The more weight you lose, the fewer calories you burn going at the same speed. But it's easier to go faster!!!
