Meaning, over time it has a weighted algorithm to note changes in your fitness level and adjust calorie burn accordingly. This little snippet below though helps to show where the technology lies accuracy-wise – with it being right in the upper-middle compared to full-board lab operations on one end, and ‘distance/time’ calculations on the other end (click below to expand picture).įinally, this metric also ‘learns’ you as an athlete on a given device. Firstbeat has published a fascinating white paper detailing the technology and accuracy rates. This makes the system one of the more accurate non-invasive options (read: doesn’t require a laboratory), within about 10% accuracy. Specifically, it evaluates the time between heart beats (beat to beat) to determine estimated MET (Metabolic Equivalent), which in turn is used determine actual work expenditure.
It then combines this data with heart rate information from the ANT+ heart rate strap. Their calculation uses user inputted variables including gender, height, weight and fitness class. It’s developed by a Finish company ( Firstbeat Technologies) that has its roots in calculations around Olympic athletes, specifically Nordic skiing. But it’s actually not developed natively by Garmin. Here’s the list of current devices, and levels of compatibility.Ģ) Firstbeat Algorithm (Current – 2nd Generation): The Firstbeat algorithm is the most accurate Garmin device calorie measurement that can be done without external testing.

I’m looking to get a New Leaf test done and put together a post or series of posts on the experience and accuracy I see.

Once a test is complete you can download your ‘profile’ into your Garmin device to get the most accurate calorie burn metrics when combined with a heart rate monitor. The tests don’t cross over, but there are tests available for running, cycling and elliptical. The tests though are sport-specific, meaning you complete a running test to allow the Forerunner to determine running activity calories.
The tests are not terribly unlike your common VO2 max test, and involve you being hooked up to tubes and wires. New Leaf is actually a 3rd party company that’s developed a pretty comprehensive way to determine calorie burn based on VO2 tests that are done. So, let’s walk through each of the six major methods, starting with the most accurate, and working our way down the list to the less accurate (the last option, Kilojoules, isn’t really ‘less accurate’ per se, but different…more in a moment).ġ) New Leaf VO2 Test Profile: This method requires testing at one of a number of New Leaf testing centers around the country. Some methods offer a rudimentary guesstimate, while others are based on scientific testing that’s then imported into your device to get far more accurate results. And not unexpectedly, the accuracy level varies based on which method you use. Then more recently last week I met up again with the Garmin fitness team to talk through all the painstaking details.Īs you might have guessed, there are actually a number of ways in which your Garmin device will calculate how many calories you’ve burned. Back when I was at the ANT+ Symposium in Calgary I sat down to start the conversation with the Garmin team there.
So, I set out to put together a bit of the definitive guide to calorie calculations on Garmin fitness devices. Further, a specific device can even product different results for the same person dependent on how it’s configured. The challenge that many folks have found out is that different Garmin devices produce different results, and sometimes – even different results for the same person. While many runners or cyclists often estimate calorie burn (and thus cookie allocation metrics) using borderline sketchy back of the napkin calculations, there’s also a significant portion of the population that looks to use their Garmin device to determine calorie burn. There are few topics that cause more confusion, intrigue and general ‘Huh?’ in the sports world than calorie burn.
