Calories and Training Effect drastically different when using my chest HRM

Former Member over 5 years ago

I have recently run three identical runs, same distance, same pace, same average heart rate. The first two I used the wrist based HR on my Fenix 3. Garmin Connect calculated I burned and average of 630 callories and a TE of 5.0 for both runs. The next identical run I used my bluetooth chest HRM (Myzone 3) which recorded an identical average HR, but now my calories burned went down to 74 and my TE went down to 1.0. There is something wrong with these metrics. So frustrated, I spend all this money on expensive equipment and very inconsistent results.

hi,

sure Garmin Connect did the calculation

I guess you have the Fenix 3 HR version

check your heart rate zone settings on all Garmin platforms,

being Garmin Connect Web, Garmin Connect Mobile and your watch

So I compared the two runs for time in each HR zone. The top one is wrist HR and the bottom is chest strap HR. The chest strap which I know is more accurate showed I was actually in the red zone half the time. Does this explain why the calories are off by a factor of 10? Still doesn’t make sense to me.

what about the above question ?

you did say three runs ?

would you please take the screenshots a bit wider so the values are on it ?

wrist HR is for daily activity tracker and belt HR is for sport tracker

there are OHR devices like polar OH-1 and scosche with good reputation while doing sports

happy & safe sporting
