How does Myzone calculate calorie burn?
Men: C/min = (-55.0969 + 0.6309 x HR + 0.1988 x weight + 0.2017 x age) / 4.184 Women: C/min = (-20.4022 + 0.447HR - 0.1263 x weight + 0.074x age) / 4.184
Myzone estimates caloric expenditure using an equation that was developed in a study published in the Journal of Sports Sciences in 2005. The equation takes into consideration the user’s sex, weight, age, and heart rate—essentially, as much information about each user as is available:
Men: C/min = (-55.0969 + 0.6309 x HR + 0.1988 x weight + 0.2017 x age) / 4.184
Women: C/min = (-20.4022 + 0.4472 x HR - 0.1263 x weight + 0.074 x age) / 4.184
Things to Know:
- Calories measurements are an estimate. Trackers such as Fitbit, Apple Watch, and others use different equations, so you will notice calorie burn may vary between devices.
-
Myzone does not track calories below 50% of your MHR. The equation is most accurate at moderate to intense activity so calories will only be calculated above 50% (grey-red zones).
