Strange heart rate curve

Former Member over 5 years ago

Hi!

I found my heart rate curve strange. It starts at around 100-140, and then after a while it pops up to the heart rate i actually have. My suunto shows a more linear curve during my trainings.

Any one with familiar issues? The last pic is from my friends 620, with the same behaviour.

Garmin provides explanation for this specific behaviour of the OHR sensor in one of their support center articles:

(...)Why does this happen?In some cases there isn't much blood in the tissue on the back of the wrist. This issue is common when it is cold outside or early in a workout before your blood really starts pumping.
How can I prevent this from occurring?When you plan to workout, warm up a bit before starting the activity. In addition to this, make sure you are properly wearing the watch.(...)
