HRV and recovery

Stefan Kersting

@Brad_Olwin the reason why I ask is because I was on a lecture where an author presented his new book “Pulskur”. It is a book about HRV (just in norwegian but it will be translated to english this year) and the autor used a garmin watch to track the stress. It was pretty interesting to hear which paramteres influence the stress/HRV. I asked about other watches, Suunto, Polar etc. but his opinion was that garmin had the best algorithm to track HRV. Have to mention that he doesn\t have a contract with garmin and the book is more general about lifestyle and how lifestyle impacts HRV. Now I am even more excited and can\t wait for the update this autumn

@Stefan-Kersting is this book also in German language?

Stefan Kersting

@GiPFELKiND unfortunately not. But it will be available in GB, USA and Australia next year said the author. I havn\t read it self, but the lecture yesterdau was very interisting.

@isazi said in HRV and recovery:

S9PP is also getting the update, with lots of changes and features. Not sure if HRV is actually included in them though

Last SA has HRV so I suppose will come. I also hope that there is a possibility to measure HRV only during sleep (I mean to activate HR only during sleep). I’m more than happy of my purchase after this news!

@isazi the S9PP manual already spoke about HRV from the beginning and I feel betrayed it wasn’t included in the first place. This is false advertising in my book.

Brad_Olwin

@twekkel I believe that HRV is used for determining the Resource score. So I don’t think false advertising.

@Brad_Olwin Resources feature and recovery times will be corrected in next update? Those features aren’t working from the Vertical launch.

Stefan Kersting

@jjpaz why didn’t it work from the launch?

isazi

@jjpaz yes, no more firstbeat, all algorithms are new. Still some testing needed, it’s a big change, but coming Autumn 2023 (as far as I know).

DMytro

@isazi to all devices that had firstbeat previously or only to the recent ones?

isazi

@DMytro can’t comment, don’t know the plan for old UI devices.

@Stefan-Kersting There are two issues here:

1: Resources “graph”: Resources increase when you rest and decrease when there is stress. OK but that decrease process is very random. Sometimes you go for a easy run and suddenly resources decrease to 0%. Also, when you charge the watch resources “reset” and start from 50%.
It is also not clear which HR value should be set as the resting HR value.
Some people configure the minimum HR when sleeping, some people the rest HR when resting sitting… If you configure the minimum HR is nearly impossible to reach 100% resources and is very easy to go 0% after a short easy run.
In my case I ignore the resource function.
2: Recovery time: the timer is also random. You finish an activity and the watch shows a recovery time. With old watches that timer is decreasing hour by hour until reaching 0h, at least in my S9B and S9P was working that way. In the Vertical that timer is frozen several hours, then decrease by some hours, then freeze another time. Sometimes always shows the original recovery time until the hours are completed and changes to 0h… Random. And this feature was working fine in previous models.

I understand that, if Suunto is changing the recovery algorithms, it has no sense to invest resources in correcting this feature but then I hope that this feature will be corrected with the new algorithm and software.

@jjpaz yes it is important to find out the rest HR to configure the ressource calculation right. there are discussions aabout that in this forum too. I have not figured out which rest HR I should take. Anyway, I think it is not the right approach to get 100 % ressources when getting up in the morning. Our body is little more complex than that. A cold shower or a big pizza late in the evening will impact you stress level/HRV, so there are a lot of factors that are influencing you ressources.

I don’t use the recovery time that much. Often I get a recovery time of 120 hours, especially after some hours on skimo. I am listening more to my body and the recovery time seems to be a little bit unrealistic sometimes. Maybe the math is right, but my body doesn’t feel for a 5 day recovering period

Using this existing thread to note that with the new Vertical update, my reported nightly HRV is consistently about 10 less than what my Garmin 7X is reporting. I will continue to see if it reconciles eventually.

Not poking anyone and really not wanting to offend, but I see a number of these comments that ‘my Suunto is not the same as my…’ I work in the world of metrology, where nothing is ‘correct’ in absolute terms: i.e. everything has a level of permissible error. I have many conversations about this: just because you compare one thing with another, neither is necessarily ‘right.’ It’s a comparison between two devices. Arguably, the Suunto may be more accurate than the Garmin!
