Calories are a measure of how much energy you expend. Pacer calculates the number of calories burned based on formulas provided by the Journal of Sports Sciences. These formulas take into consideration several key factors to estimate your calorie burn:
5. Activity intensity
The number Pacer provides for you is a net calorie burn, which simply means that it is how many calories you burn from your activity. The number of calories you burn in a day is actually much greater than your net calorie burn, even if you are not doing any physical activity at all.
Of course, our calorie expenditure is only an estimate based on the best statistical models available. As such, calorie burn values are not exact, but they do provide a useful tool to measure your relative levels of physical activity over time.
