Versa 2 on Android app showing incorrect Hear rate zone

[versa2_freak]

My versa 2 recently did an update. After that, the Heart rate zone is not calculate correctly.

My max Heart rate was 164bpm. However, the Heart rate zone shows 100% below zones.

Any suggestions?

Thank you.

The recent update changed from Active Minutes to Active Zone Minutes and, as part of that, they changed the ways the heart rate zones are calculated with the new method taking into account your resting heart rate.

There are a couple of help files that go into detail on this. This one explains Active Zone Minutes: https://help.fitbit.com/articles/en_US/Help_article/1379.htm and this one covers the details of the heart rate zone changes: https://help.fitbit.com/articles/en_US/Help_article/1565.htm

I got this update and the new zones don't make sense to me.  I'm 53 years old and currently have a resting heart rate of 68.  How on earth can a brisk 60 minute walk give me zero fat burning minutes.  If this is correct, it's very demotivating.  

My zones are now:    107-126 fat burn, Cardio 127-151, and now peak is 152+. 

Is this correct? 

[SteveH]

Using the calculations described in that help file your zones are calculated as:

Max heart rate = 220 - age = 220 - 53 = 167

Heart rate reserve = max - RHR = 167 - 68 = 99

Fat burn = 0.4 x reserve + RHR = 0.4 x 99 + 68 = 107.6

           to   0.59 x 99 + 68 = 126.41

Cardio = 0.6 x 99 + 68 = 127.4

         to   0.84 x 99 + 68 = 151.1

Peak = 0.85 x 99 + 68 = 152.1

So, it seems that the calculations are correct and you now have to get above a heart rate of 107 to get active zone minutes and above 127 to get double active zone minutes. The changes seem to effect different people in different ways. I'm older than you but have a lower resting heart rate and my fat burn start is 97. I think we just need to forget our old data and start again with this new way of measuring effort.

Thank you. I found the same formulas last night. I guess I will have to kick it up a notch if I want the positive feedback!

Steve, I think you’re right. And heart.org is wrong.

but how can you explain this.

My RHR = 55

I set my max to 167. Nothing changes.

after some calculations my max should be 180.

So I have a body of a 40 year old. 😁
Not so bad.

Calc:

105 (fatburn) - 55 = 50 = 40% of reserve, so 50/40% = 125, so max = 55 + 125 = 180. Or

130 (cardio)  - 55 = 75 = 60% of reserve, so 75/60% = 125 etc Or

161 (Peak) - 55 = 106 = 85%  Etc.

I'm sorry @MarioDings I'm not understanding the question. Is it that the chart is not updated if you override your max heartrate? I've not used that override myself.

[MarioDings]

@SteveH the problem is gone. Now it’s working as it should.
