Hi,
I use a Garmin Fénix 5X with a Wahoo Tickr and the 3 app in the Garmin Connect IQ Store (Test HRV - HRV Analysis - Heart Monitor+HRV)
I teste this in the same conditions and have this
My question is:
Watt´s the correct value to use in Intervals.icu? for example
This for me is very strange, I teste all this type of application (Elite HRV, Kubios HRV, HRV4Training, etc. etc.) and never found similar results, is this something that everybody talk but that is uselessness.
Regards
In practice it is not very important which quantity you use, as long as it is a statistical measure of deviation from average heartbeat length. Different apps will use different ways to express this.
For example, RMSSD is the “root mean square standard deviation”. If you would plot all heartbeat lengths as a histogram, this quantity will characterize the width of the distribution. And if all your heartbeats are the same, it will be 0.
Now you can track this value with time to see what is the typical range for you and how the training affects it. As with reading heart rate, there are no strict guidelines.
I’m not sure what’s up with the last screenshot where RMSSD looks strangely small and not in tune with the Ln(RMSSD).
tl;dr after trying several things with HRV I find it too complicated for an amateur athlete
And in my opinion, maybe I´m wrong, but one more unnecessary value, that maybe is a lost of time checking this.
All app that I test no one send anything that match, and this is the problem, that leave me to think that nobody know the perfect values for this, and how to use them.
There are people with good experiences with this. French biathlon team has published good datas.
On an amateur side, Marco Altini from HRV4TRAINING is top notch on the topic. But I found that you need of inputs (sleep, training, feelings) to put HRV variations in perspective.
Usually RMSSD is a good metric to follow. But it’s complicated. One cannot say that low is bad and high is good. You should more look at the amplitude of variation from one day to another and if it moves in the expected direction.
I always get a normal/high HRV rate after a hard ride…i expect to get a lower value. After the restday i got a real lower value…on trainerroad i got this info what is right with my measurements.
The key things with HRV is to learn to listen to you body. It helps you to learn how your body react on training. If you get a low volume you can do your normal training, but maybe its better to dont do to intensive (vo2max etc).
Never compare with others. Only you and yourself and looking for trends after 2 months of reading.
I talked with my acupuncturist about this yesterday. She explained it as a normal body response to exercise stress. The cycle is about 72 hours. In 24 the body is just climbing the hill to recovery. Between 36 to 48 hours it peaks and 72 full recovery. Aligns with why you want at a minimum of 48 hours recovery after strength training. The heart is a muscle.
@Joao_Samora I suggest you read all the articles in Blog Posts They have an ultimate guide which explains everything about HRV. Read that and you should get many answers.
As a short answer, it’s not about the numbers but it’s about their interpretation. The best tool for me is hrv4training. Solely inputing a value like (rmssd) in the HRV field won’t help you much. It’s all about the context.
