Show Me Your HRV

Postby samccauley » Fri Mar 25, 2016 8:12 am

Goofy subject line, I know.

I thought HRV value should be fairly consistent, changing slowly with improved fitness. But mine seems to jump round a lot from as low as 49 to as high as 99.

I use a Garmin 920XT. My HRV is all over the place. It seems to vary based on the type of workout. I've copied the values from SportTracks.mobi into a spreadsheet to see if I can spot a trend. It seems like each of my workout routines have a general range for the HRV value. If I sort it by activity type, this becomes more clear.

First, my chart directly from .mobi:

Now, the spreadsheet in date order:

Finally, the spreadsheet sorted by activity type:

it's interesting to look at RMSSD over night.

it should trend upwards. (can probably do a regression line or similar)

this means you have achieved a degree of recovery/adaptation.

well I thought it was interesting

What equipment do you use for HRV measurement ?

I am a cyclist.
As far I know the market for this piece of equipment, options are very limited.
I want both GPS data, power+cadence (ANT+). distance, speed+time, HR (ANT+) and HRV

It looks like I have to buy an extra watch, used by runners, only to keep track of my HRV
A pricetag of EUR 300,-
Am I right?


Note; I think the screen of multisportwatches is too small when used while cycling.

you can probably record it onto apps on a smartphone in your back pocket for free or next to free tho you may need a Bluetooth strap for those. I haven't done the research on which apps would do that whilst cycling.

I am a he.

After my last post I have done some reading on this subject
And I found out you do not have to measure your HRV all day.
One measurement on a fixed moment in your daily routine is enough.
So I do not have to look for devices capable of measuring HRV, which I can use on my bike.

I always thought you had to buy a top of the range sportwatch in order to measure your HRV.
I did not know an accurate Bluetooth HRstrap together with a phone with some app installed, could do the job.

Things get more expensive when you have a ANT+ HRstrap. Like me.
At this moment I am trying to find out whether a ANT+dongle, or a simple fitnesstracker collects all of the data from the ANT+ HRstrap which are necessary for HRV-analysis on a PC.
Or whether I need a real sportwatch with extra capabilities (like the 920XT) for HRV-analysis on a PC.

Yeah. I believe I've read that it's best to measure HRV at the same time each day, preferably while resting! That's a far cry from taking it while working out.

But, I like that I don't have to do anything to collect these values. I don't need to remember to measure my HRV each day, week, whatever. So, while it's strange that the Garmin collects HRV during activities, it's also convenient.

As I've written before, I'm not confident that measuring HRV while exercising is very meaningful.
To my best knowledge, it's a measure for level of relaxation vs. stress, when measured while at rest.
When you're relaxed, your heart strolls around like a little doggy, peeping here, sniffing there, resulting in a somehow jumpy heart rate pattern, i.e. a high value of rmSSD.
When you're under stress, your heart beats in goose-step, resulting in low rmSSD.
Less lyrical, HRV results from the antagonism of your sympathetic and parasympathetic nervous systems.

What basic equipment do I need for HRV-measurements, to get into business for an affordable price ?

    I already have got a Garmin ANT+ HRstrap
    Any ANT+ dongle (USB2.0 for PC)???

Did I understand well ?

ST3+LiveRecording plugin works like a charm.

I have both [*]tried[*] used the Garmin ANT+ mini stick and the Suunto Movestick mini to transfer HRdata from my Garmin ANT+ HRstrap to my PC.
The Garmin asks for installation of Garmin Express and its dozens of updates to install the drivers.
The drivers for the Suunto can be downloaded apart from a Moveslinck account.
I also think the Suunto is more sturdy.

You can't transfer data from your HR strap directly.

You CAN - using Live Recording Plugin. All you need is an USB ANT stick - no Garmin or other device needed. You'll even get heart rate variation data, without having to use one of the more expensive Garmins, which support HRV.

And... if you have a Bluetooth SMART HRM you can use a variety of apps to record HRV too - no need for a Garmin.

Our preferred iPhone app is HRV4Training. It has direct integration with SportTracks and is only eight bucks. The guy that designed it is super responsive and there is a lot of technical info about HRV he publishes.

It also has a camera detection mode - no strap necessary.

So, how can I get ST3 to show me my HRV? I have done everything as described to get ST Mobi to show it, but what about ST3 Desktop?

ST3 doesn't track HRV, it's only in the SportTracks online product.

Two options to analyse HRV in the desktop app:
1. use Live Recording plugin (+ an ANT USB stick and a heart rate strap) to record and display your HRV
2. record HRV data with a Garmin device, which is capable of this (e.g. my edge 520 can do so); use Garmin FIT Devices plugin to import .FIT files with HRV data and Live Recording plugin to display HRV

3. Third option: Place requests in the Enhancements Forum and on the user voice site for ST3 to be as complete as the online app with regards to tracking this metric. ST3 has been updated to support current devices in the past, it seems that ST3 should continue to evolve to support modern devices.

If you use an app to track your HRV there isn't currently an automated solution to sync this to the ST3 app. OMB's suggestions don't really help. As well, those HRV data in ST3 won't sync to SportTracks online, so it's not much of a solution. There isn't any HRV field in ST3, so it's probably a custom defined field we won't know about to sync. You'll need to enter the values manually.

Here is the related idea to enable ST3 <> SportTracks sync:

Cast your vote and subscribe to the issue if you're interested. This idea is also somewhat related:

We're looking at custom health metrics but there are a few higher priority items above it right now - structured planned workouts, aggregate time in zones, weather and compare top the list.
