HRV on Vertical

duffman19

question to experts : shouldn’t it be the opposite ? higher HRV in case of illness ?

Definitely not an expert, but I believe your system is more stressed during illness, so the sympathetic system takes over resulting in lower HRV. When healthy and relaxed, the parasympathetic system is dominant and HRV increases.

actually when i got fever my HRV drop a lot. dropped to 18. normal day my lowest is 33. so quite big different actually.

Mine is 30 something where is the chart about hrv and age?

Todd Danielczyk

@babychai Pretty cool how it reaffirms your health like that! I had similar results where I got busy at work and run down and my HRV trended with how I was feeling. Pretty good indicator to take it easy or know that we are coming down with something!

@Todd-Danielczyk Indeed nice to see this HRV trend to monitor our health and stressful life

@babychai And beers

babychai

@inkognito Wow, you should drink lesser then

Todd Danielczyk

@inkognito Ah yes! It is well documented how HRV is affected with alcohol consumption.

In a way I’m glad I didn’t track my HRV in my youth with all the trade shows I went to

@inkognito I found that beers before bed affect my sleep HR and HRV much more than hard training or getting sick

@Mff73 sickness, stress, poor sleep and recovery result in low HRV. Good sleep and recovery, low stress, good fitness result in high HRV. Plus it’s also a bit genetics.

@Mff73 i feel the same too. my fever also got make HRV drop

thanks to all to correct me

HRV indeed is an indicator of illness, “drunkness” also, tired periods…
It’s directly linked to HR : the higher is the HR, the lowest the HRV should be. But low HR doesn’t mean hight HRV.

But before HRV was introduced, HR at night itselft was already a very good indicator : I can easily find every night I have been partying or drinkink too much, or been hill => my HR at night directly jumps from 40/45 bpm to 60/65.

So HRV is certainly an interesting indicator, but at my athletic level, I still don’t know excatly how I will be able to use it. For now I imagine to combine it with CTL/TSS tracking to sometime decide not to go training even if I want to. Somehow helping me “train better, don’t train more”.

kamarasm

@Tieutieu yes, I think so, trends are important.
However I checked HRV during illness. It was 9

@Tieutieu Perhaps more than an aid in training, HRV is important as a warning against a heart attack condition or problems with heart function, because according to my friend, when the heart beats to the rhythm of the metronome (HRV goes towards 0), we are about to have a heart attack.
Of course, this is not a scientific explanation, but it seems logical and reasonable to me

@Miš-Kan thanks, didn’t knew that !

I have only had my SV about 10 days, so not enough to get the full 14 day average. On top of that I have had a really bad cold over the last week, so maybe my current HRV is a bit low because of that - currently averaging 21 ms (Resting HR is 55, and I am 62), with last night only 19ms ‘apparently’, although I feel I am through the worst of the cold. I am ‘reasonably’ fit (for my age?), but it still seems rather low.
I’ll keep watching over the coming weeks…

Do you have any scientific proof of this apart from “friend” and “seems logical”?

To me it sounds a lot like an urban legend…

Tieutieu

@Egika. While trying to get some informations, I found that (french partially english). But there must be more litterature about it.

“Coronary heart diseases : Several studies indicate that a drop in HRV is associated with the risk of cardiovascular and coronary pathologies, hypertension and insufficiency cardiac [10].”

Mouse Cruiser

@Egika First of all, I should say that I am a technician and not a doctor, so I interpret some explanations in my own way. Since you want a more in-depth medical read, I suggest starting with one of the articles that summarizes the following:
Low heart rate variability (HRV), a marker of cardiac autonomic dysfunction, has been associated with increased all-cause and cardiovascular mortality. We examined the association between reduced HRV and incident stroke in a community-based cohort.
Source: https://www.ahajournals.org/doi/10.1161/STROKEAHA.116.012662

Urban legend or scientific fact? Judge for yourself.
As I said, I simplified and it seems logical and reasonable for me.
