Elevation on a treadmill

Former Member

Hi,
I wonder why editing elevation of my runs on a treadmill, doesn't change the stats of my run for example "Calories".
My Forerunner obviously doesn't record my elevation for treadmill runs.

    Elevation by itself does not enter into the calorie calculation. It appears that heart rate is used by most fitness software and of course going uphill will increase HR. So....you need to wear a HR monitor :)

    That doesn't make a whole lot of sense to me... A person with a lower heart frequency doesn't use less calories, for the same effort... Having a better condition, doesn't make you burn less.
    I use a heart monitor, for my Forerunner 630.
    Thanks for the reaction though! :)

    Well, I'm not going to explain the science behing this, but a person with lower heart rate DOES use less calories, given the same age and weight, for the same effort. A very fit person will use less calories to run a mile in 6 minutes than an unfit person - again given both persons have the same body weight.

    Don't ask me for details - I'm not an expert in this field, but most calorie calculators - including those in fitness devices - lead to such conclusions. You can try for yourself - there are online calculators available.

    So to cut the story short:
    To calculate calories you need heart rate, body weight and probably age and sex. Having these parameters, treadmill elevation does not add any additional data into the equation.

    One more side note: Some fitness devices (like treadmills or stationary bikes in public gyms) can give a calorie estimate without heart rate data, but this is a very rough estimate, based probably on general population averages, and in this case a change in treadmill elevation might give a higher result.

    This is an older article but it's still relevant to how calories are calculated on most Garmin devices (though the FirstBeat algorithms may have been updated since then). https://www.dcrainmaker.com/2010/11/how-calorie-measurement-works-on-garmin.html
