How Garmin Calculates Calories Burned
Before diving into the accuracy of Garmin’s calorie burn estimates, it’s essential to understand how the company calculates this metric. Garmin uses a combination of factors, including:
Heart Rate Data
Garmin’s wearable devices, such as the Forerunner, Venu, and Vivo series, collect heart rate data through electrocardiogram (ECG) or photoplethysmography (PPG) sensors. This data is then used to estimate the intensity of your workouts and, subsequently, the number of calories burned.
Activity Type and Intensity
Garmin also considers the type and intensity of your activities, such as running, cycling, swimming, or strength training. This information is used to adjust the calorie burn estimate based on the specific demands of each activity.
User Profile Information
Your personal profile information, including age, sex, weight, and height, is used to calculate your basal metabolic rate (BMR), which is the number of calories your body burns at rest. This BMR is then used as a baseline for estimating calories burned during exercise.
Algorithmic Calculations
Garmin’s proprietary algorithms combine the above data points to estimate the total number of calories burned during a workout. These algorithms take into account factors like exercise duration, intensity, and frequency to provide a comprehensive estimate.
Accuracy of Garmin’s Calorie Burn Estimates
So, how accurate are Garmin’s calorie burn estimates? Research suggests that the accuracy can vary depending on several factors.
