Heart rate monitor values depending on activity choosen?!?!

Former Member over 4 years ago

There is someting fundamentally flawed with the HR measurements... While in a activity mode like "walking" it will correctly record your heartrate, but if you take a walk without any activity mode activated, the HR measurements will register very low, around 30-40 bpm lower overall, on the same route!!

I have tried with gps, gps + glonass & without gps. All walking activities report higher bpm than if the device was used without an activity chosen. I wear the device at the same location and with the same fit on my arm every day...

Anybody else here get different readings for their walking activities vs. walking without activity choosen?

I do indeed get different HR reading depending on which activity type I choose, and it makes sense that the watch does that. My heart rate when walking is usually around 90, so the difference to no activity chosen is smaller than 30-40. If the watch knows what you are doing, it can measure your heart rate more accurately.

This leads me to believe this is a very stupid device...

Each activity profile has its own algorithm. When you choose an activity and the device knows what it is you are doing it can measure the HR accurately.
