How to define the heart rate zone?

How do I have to define the Heart rate zone in the VENU 3S?

I'm trying to define the Heart rate zone in the connect application.

What do I have to put in the max heart rate field? Is it the results of the formula 220 - age or should I put the max heart rate measured during an intense activity (In my case, the max heart rate measured is higher than the result of the formula).

I've put the resting heart rate reported by the watch in the resting heart rate field. Is it correct to do that?

Why does the watch need to know the resting heart rate?

And finally, how do I have to define the 5 zones?

I currently defined them as following: 50-60%, 60-70%, 70-80%, 80-90% and 90-100%.

Is it correct?

I ask this question because I have seen on some internet sites people defining the max heart rate zone with the formula 220 -age and then defining the heart rate zone starting to 60% - 70% in zone 1, stepping by 10% and ending at 100% - 110% in zone 5.

However, in the connect application, it is not possible to define a percentage higher than 100% in zone 5.

Thanks.

    Hi,

    The formula 220 - age for the maximum heart rate is a very rough estimation. It doesn't work either for me.

    The heart rate zones are defined as % of maximum heart rate or % of heart rate reserve (maximum heart rate - resting heart rate).

    The latter is considered more relevant.

    The problem is the resting heart rate is not taken into account on the Venu 3. See my post on the subject.

    Regarding the definition of the zones, personally, I've left the default % values.

    Hi,

    Thanks for your response.

    I've read your post and will try ro summarize my understanding using my own heart rate data.

    The first thing I understand is that you are recommending the use of the default heart rate zones definition (50-60%, 60-70%, ...).

    In my case, for an unknown reason, the default heart rate zones definitions had changed.

    I now see two different methods to set the heart rate zones:

    Case 1: Heart rate zones defined in function of max heart rate frequency only

    In my case, I've measured a max heart rate of 170 bpm.

    So, this would give: Zone 1: 85 -101 bpm, Zone 2: 102 - 118 bpm, Zone 3 : 120 - 135 bpm, Zone 4 : 136 - 152 bpm and zone 5: 153 - 170 bpm

    Case 2: Based on Heart Rate Reseve

    The watch indicates a resting heart rate of 48 bpm. The reserve is then 170 - 48 = 122 bpm.

    Let's define heart rate reserve as HRE, resting heart rate as HRR, and X as the percentage of HRE to use in a zone.

    I'm guessing the formula to use for the calculation based on heart rate reserve is HRR + X * HRE 

    So, this would give: Zone 1: 109 - 120 bpm, Zone 2: 121 - 132 bpm, Zone 3 : 133 - 144 bpm, Zone 4 : 145 - 157 bpm and zone 5: 158 - 170 bpm

    Do you think it is best to use the definition of heart rate zones of case 2?

    Your understanding and computations are correct.

    My personal experience has shown that the case 1 doesn't reflect what I feel.

    The case 2 is much better aligned with the zones where I can speak or not ...

    The problem is that the resting heart rate is not taken into account currently in the Venu 3.

    And trying to set manually the % of max heart rate to match the bpm of case 2 is not easy.

    For zone 1, the maximum % allowed is 59.

    In your case, 109 bpm is 65% of your max HR. So this won't work.

    So you need to use a fake max heart rate e.g 200 to have % that are allowed in each zone.

    That's not user friendly to say the least.

    I hope that Garmin will fix this issue.
