I'm flumoxed, how do they calculate it
I've just started using a vivosmart, previously I'd been using the forerunner 210 in conjunction with a mio link hrm to log my cardio workouts.
Today I used both...expected the calorie burn to be different but not that different
I ran/walked uphill for 80 minutes, my average heart rate was 83% of max.
Forerunner said a disappointing 435 cals:(
Vivo smart said a shocking 865 cals
Now the calculator here:
www.shapesense.com/fitness-ex...alculator.aspx
(the one where you fill in VO2 max-I estimated my VO2 max from my heart rate after a 1 mile jog based on the calculator here www.brianmac.co.uk/vo2mile.htm)
gives me a calorie burn of 737 for the same workout so it seems as if the vivo smart is the more accurate of the two.
I know these calorie consumption figures are all only estimates but is it not weird that devices from the same manufacturer would give such different readings?
Does anyone know if the two devices use different formula to calculate calorie burn?
Furthermore is that formula any more sophisticated than the one I linked to which asks for weight, age, gender and VO2 max?
