I sometimes get erratic heart rate data during an activity. This has a negative effect on the accuracy of the performance measurements like training status and on the suggested workout. Is there any way to mitigate this - for example, by editing the bad HR data?
Hello, I am having the same issue. In all my runs, my HR is being measured incorrectly (about 25% higher). It has started approximately 4 weeks ago. It will quite suddenly jump up (usually into the HR Max range) and sometimes will drop down just as quickly. It is not weather dependent. I am using the wrist sensor. I have turned Pulse Ox off (I had previously been told that this was the cause) and my watch has <90% battery. I run consistently in the morning. I have a screenshot so you can see the typical issue.
All these Optical Wrist Based Sensors have the Same Problem most Visible in Running Activities and Weight Training Activities. I's Caused by The Movement of the Body.
Cycling is Actually Fine Because Your Wrists are Stationery, When You Rest and Sleep It's Fine.
On Slow Walking Activity it does make a few mistakes but not as much as Running Activity.
The Simplest Way to Correct the Issue is to Wear a Chest Strap HRM during Activities. Any Chest Strap HRM that Supports Ant+ Protocol Should Work. I'm Currently Using the Kalengi HRM with A Polar Soft Strap and It Is 100% Accurate.
