Estimated calories vs. meassured calories (Read 167 times)

    As some have pointed out, calories expended is not a directly measured value, where as distance, duration, heart rate, weight, temperature, etc can be measured readily.  Calories can be measured by measuring your CO2 output.  All other methods are estimated based on other data such as weight and heart rate.  Only directly measurable values are stored.  Derived values are calculated on the fly based on known formulas.

     

    As a commentary:

    Calorie is a measure of energy consumed while doing work, such as moving your body from point A to point B.  The amount of energy consumed is mostly a function of your weight, the distance traveled horizontally and vertically (which is why walking consumes fewer calories than running).  To some degree, some energy is expended to overcome air resistance.  I have not seen the formula for determining calories by heart rate so I can't say whether it is accurate.  I believe that it merely refines the value obtained by weight and distance.

      But if the dummy is running that many times in a day  

       

      You shouldn't talk about AmoresPerros that way.  Smile

        This thread is delivering in so many ways!

        Well at least someone here is making relevance to the subject.

          A little later in the day, same dude goes and runs the same 5 mile course, but now it is 78 degrees outside and so his heart rate is higher than when he first ran. Still 9 m/m, but a higher HR. Still burns x calories.

           

          Is this because he is not acclimated due to the polar vortex? Is that even still a thing?

            I don't know about up north. It left NJ some time ago.

            Hope that fecker stays away too.

                  According to the American College of Sports Medicine, calories burned per minute are determined by your weight, your speed and the incline.

                   

                  Walking: VO2 = (0.1*S) + (1.8*S*G) + 3.5

                  Running: VO2 = (0.2*S) + (0.9*S*G) + 3.5

                   

                  Where:

                  VO2 - gross oxygen consumption in mL/kg/min

                  S - speed in meters per minute

                  G - percent grade expressed as a fraction

                    So...  if I run downhill I actually generate calories instead of burning them!  Cool!

                          Maybe *you* want to put a checkbox in your log. I don't.

                          It's a 5k. It hurt like hell...then I tried to pick it up. The end.

                              Lots of things cause heart rate to vary during exercise (and while at rest). Most of them have nothing to do with caloric expenditure.

                               

                              That was an assertion, which is different than a question.

                               

                              Further, I know a thing or two about physiology. Science is not important so long as I can make this personal. That is what this thread has taught me.

                                I wonder if BAC has any impact on HR while running?
