HRV on Vertical

[kamarasm]

If I understand it well, graph appears just after 14 days. As probably all of us updated watch immediately after the new firmware got out, graph should be available in the same time.
Based on it - with my low numbers - I’m in the normal range. I guess it is because it looks the trends.

But I still really curious on why and what means these unnormal low values.

With just 14 days of history, my personal observation (without any scientific knowledge on it) is that my night average HRV is little lower after a day with training.

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

[Egika]

@Mff73 no. less rest, higher stress on the body resulting in smaller variability.

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

[inkognito]

@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

[Likarnik]

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

[A Former User]

@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.

thanks to all to correct me

[Tieutieu]

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

[Mouse Cruiser]

@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
