Rest heartrate question

[Merkillin]

Hey,

I thought my Fitbit Charge hr was supposed to track my lowest heart rate level?
I woke up last night a few times and I saw far lesser readings.
I have been reading about how the rest heart rate might be higher asleep than awake. Yet I did see numbers like 55, but the fitbit charge hr logged this time a 70.
It's baffling to see this, but I'm just wondering if the system is designed to take readings in a certain time?

Hi @Merkillin

From the Heart rate FAQs 

Resting heart rate refers to the heart rate measured when you’re awake, calm, comfortable, and have not recently exerted yourself. Your tracker estimates your resting heart rate by measuring your heart rate while you’re asleep and while you’re awake but still during the day.

For best accuracy, wear your tracker to sleep.  If you don’t wear your tracker to sleep, the tracker will still try estimate your resting heart rate while you are awake.

Resting heart rate is usually higher than your heart rate while you are asleep, so don’t be surprised if your resting heart rate is higher than the lowest number that you see in your heart rate graphs.

This gave me more questions than answers....

First of all I'm seeing lower numbers on the fitbit itself, when I'm resting during the day and woken up during the night.
The device gave me 70 during last night, but it saw 58 when I was in the toilet. Just now as I'm lying on the bed awake, I watched 54 bpm:s on the app.
So it must be that the device is configured to take those readings from a specific time, rather than the lowest bpm?

I'm just trying to understand the habits of this device...

@Merkillin We are all waiting for an answer to your query. We know the Fitbit Algorithm keeps adjusting the calculation over 24 hours and we are waiting with baited breathe, " what is the time interval that Fitbit considers resting"?. I know when I first awake my RHR jumps a few points and then after about 2 hours it settles down again.  For 2 hours last night my HR averaged 47 bpm dropping to 41.. A generic slow HR.

[Merkillin]

I turned into the customer service in Twitter for this. And here's a quote

@Merkillin It is estimated using your sleeping and waking (at rest) heart rates. Learn more here: https://t.co/KhqkfDgcfs. Hope this helps!

And I have just replied..

@FitbitSupport actually I'm disagreeing with you. You should not use this term rest log if it has nothing to do with it.

You see I've bought the device just to see my hrm:s, and they are not giving me it. It's actually my main concern, to be able to keep track of the hrm:s. I'm not interested in an estimate, I need the exact number

And I have replied that I'm actually going to search for a 3rd party apps now for seeing this.

@Merkillin Many of us are interesting in Fitbit's definition but I get no results in Twitter for your link.

[Merkillin]

First of all, that's all the definition they have given me. I'm waiting for the next answer myself.
Then about finding me, I'm not sure can you find it, because fitbit support isn't following me yet. So I'm not sure are those conversations public?
I have posted our conversation of its best parts here, they have only thanked me for the first question.
After that I've just gotten critical, of which they haven't replied.

[Merkillin]

I'm interested in why they have given us an estimate to follow, rather than a specific number.
As I'm aware that one of the key factors of following one's health is the rest heart rate. Then the amount of oxygen and the amount of lactic acid in one's blood stream. And as the common man's reach is able to get these activity trackers, not the latter two, it's meaningful to follow one's rest heart rate.
And I'm all the more curious of what's the reason behind this estimate.

In my opinion, the folks behind fitbit have created the support pages for the greater public, not the enthusiastic people like me.

[Colinm39]

@Merkillin I'm still playing around with Custom Activities and examining my Sleeping HR. I have extracted 45 minutes using the Custom Activity.

As I'm typing this my HR is 57 bpm. and today's RHR is below

[Merkillin]

As I'm trying to figure out your pictures, I even searched for an app while doing it...
This seems to be the fitbit's own custom activities page? Can you command the device to follow my real resting heart rate?

I haven't thought of that...

Yet, I figure that fitbit should include this as a simple task, not one that's found only by community members

@Merkillin That is why I have been creating my 24 hour HR graph but all I need it the time slice that Fitbit consoder "a period of RHR".  Then I maybe able to extract those portions and see how they are calculating RHR.

[Merkillin]

I'm going through a surprisingly tough time, as our bed changed and I'm getting used to the new harder mattress. My entire torso is sore, and this understandably makes me a bit cranky

Back to the matter at hand..
If I gather correctly, these pictures are from a computer screen and from the premium version?
I opened my laptop, and I have the premium tryout week going on.
There lies another problem, I'm most of the time relying on my phone. I'm on my laptop maybe once a week. And what I can gather, the premium isn't available for the app?
So why should I pay for something I'm unable to use.
And coming back to my original point, as they are showing us the estimated number, they should easily be able to include an option for seeing the real rhr on the app.

And as to your advice, this seems a bit of a task to get done. And of which you have accomplished, good for you.
But again, isn't it the company's plan to mainly develop their app? That is because people are relying on our phones. So, shouldn't they develop the app?

@Merkillin Firstly the Graphs I'm producing are on a computer screen and aren't from Premium. They are only Custom Activities which produce the Graphs like a manual activity. The downside is it averages the calories over time and you may lose Active Minutes.

If you need to analyse your steps and pace your click on the Large Stopwatch and create that activity and examine the one minute graphs there.

The future is phones so Fitbit should be putting more emphasis on those.

Also now that you are in the Weekly Premium trial, if you discontinue that there is a good chance you can't adjust your Calorie Burn Goal which, while in Premium is Activity Cals (Trainer) goal + BMR.

We will worry about that if you doin't continue with Premium.

I use Firefox and Chrome on the phone and can create the graphs via that if necessary.

[Merkillin]

The tryout is only a glimpse of what is offered. So it's news to me that calorie burn can't be adjusted then. What else an I getting and losing if I don't continue with it?

I'm reluctant to pay for it, because I'm not interested in most of the properties that are offered. Like the caloric burn. They are only funny numbers that I get with it.
And I'm even more reluctant to get the coach, because I'm using, in my opinion, the best coaching fitness application there is. The freeletics coach. And I'm paying for it.
So if there's a reason you know what the app would give me and I wouldn't have to get the coach, then I'm interested.

[Merkillin]

How do you create graphs via phone browser?

[Colinm39]

I have just used Firefox on the Android and used a Custom Activity and then screen captured.

@Merkillin Unless you are into measuring your activity against your peers or  wan't to see how you are tracking over the past 12 months it is probably not for you and you will need to contact Fitbit when the problem occurs unless they have fixed it by then..  P{remium does not have any HR advantages.

Your contact will be @ErickFitbit

I'm a bit tempted to see against my peers, but I want to know what will happen with a trainer if I chose to accept the premium membership? Is it mandatory to take or an option?

@Merkillin It is mandatory and is the baseline of the system. I'm in dialogue at the moment with Fitbit because I have found a 20% higher error in the Activity calculations and because of this it stretches your Calories Burned Goal and it is difficult to reach that unless you lower the Activity Cals (Trainer).

I have lived with it for over 4 years and being a retired engineer it gives me some  brain fodder so the $50 PA is cheaper than doctors....

@Merkillin Fitbit are working on Premium to double their penetration as announced in the Public Offering recently so that's why I'm hanging in their because we will see improvements.
