HR zones and Max HR in Activity review window don't correspond to device setting

Former Member over 7 years ago

Hello

I have computed my HR zones using HR reserve method. I have uploaded them to my device Vivoactive HR and I can see them on device page. But when I open my activity page where I can see my average and max HR during, workout bpm is OK but "% of Max" and "Zones" tabs show different zones and %. Those computed from HR max. Is that right behavior? I would prefer to see HR % in zones I defined myself.

Painting in one of the photos shows what is happening with HR zones.

Thanks Martin

The “Max HR” in the activity summary statistics refers to the highest heart rate recorded during the timed activity in question, not what is specified in your user profile as the highest heart rate you expect to ever physically exhibit in the normal course of your day (including when undertaking vigorous exercise). If the Max Heart Rate in your user profile is 185 bpm, and the highest heart rate detected during the timed activity was 150 bpm, then the Max HR for that activity record is [sup]150[/sup]/[sub]185[/sub]?81% of the Max in the user profile.

With regard to HR Zones, the zone thresholds set on your fitness wearable device at the time the timed activity started are preserved as part of the record. You can change the HR Zones thresholds afterwards in your user profile, but they will have no effect on previously created activity records.

Yes, the “Max HR” in the activity summary statistics refers to the highest heart rate recorded during the timed activity which was 150 bpm. That is OK and I understand that. The Max HR value saved on my profile is 185 bpm. So far makes sense. Now, let's focus on value 150 bpm and the second picture. Based on value is "% of Max", 81% of HR max is 150 bpm. Still OK.

BUT my custom heart zones are all based on "% of Reserve" as you can see in the 4th picture. So 81% of Max HR is not 150 bpm but 161 bpm.

What I was trying to illustrate with the second picture was that values of "% of Max" and "Zones" in activity summary were computed based on "% of Max" not "% of Reserve" equation if you know what I mean. So 150 bpm <> 81 % of Max HR in my settings (Picture 4), what I can do is compute my zones based on Max HR and then everything would work fine. Now system seems to ignore the way zones were computed and uses just equation for Max HR zones.

Sorry, but I just don't follow your argument at all.

Forget what you want for a moment. Forget your intent. Let's pretend that I don't care, but am only commenting on what I see.

In the fourth screenshot you posted, the Max Heart Rate is clearly and consistently 185 bpm in every panel: Secondary, Running and Cycling. I don't know where the 161 bpm comes in at all.

What I was trying to illustrate with the second picture was that values of "% of Max" and "Zones" in activity summary were computed based on "% of Max" not "% of Reserve" equation if you know what I mean.

Exactly what the text said. The first screenshot clearly stated that the Max HR recorded for the activity in question is “81% of Max” (Heart Rate in your user profile), not 81% of anything else. It has nothing to do with your Heart Rate Reserve (which would take into account your Resting Heart Rate), and it certainly did not say “81% of Reserve” or “81% of HRR”.

There is no logical or mathematical error that I could see.

Martin, I get that picture 4 is you showing us your settings. What are you showing in picture 2? These pictures are both of the same settings page, but in pic 2 it's %reserve and pic 4 it's %max.
