Thank you so much. A great and clear description of HRV roles and functions. Very instructive and useful information. I am 75 years old and I am trying to make use of HRV tracking to improve my long-term chronic inflammation problems and improve my sleep as well as my living habits. Usually, I am not wearing watches and rings at all. I think I will try to start tracking my HRV using HRV4Training.
My HRV during the day is avg around 21 … at night it’s over 55. I’m 67, a woman and told years ago by the dr after a stress test that my stress levels were extremely low. I am assuming that is based on somewhat of a HRV score? Anyways, I have been trying to see why at night it is double what it is during the day. I sleep really well! Take my magnesium glycinate before bed. Just taking Magnesium Orotate in the mornings. The last 3 days my day time HRV has gone up to 28 avg and has hit as high as 55!!! Just reducing some stress? Although I never feel like I am under any stress. Have not changed how much caffeine I take and my exercise has not changed in the last 4 weeks either.
It is just crazy that Doctors do not get nutrition training in Medical schools. Every doctor visit should include some nutrition discussion. The majority of the population is over weight or obese leading to high blood pressure, heart disease and cancer. Schools and hospital cafeterias should be leading the way to good health by setting the example of what is a healthy meal and teaching people what to eat and why.. Every person in the hospital for heart disease should have a nutrition class before being checked out from the hospital with follow up education and training in nutrition. Medicare and Medicaid should require patient nutrition education as part of their standard of care. Nutrition information should be run on the hospital TV channel.
No they shouldn’t, because every part of the human body is so unimaginably complex, and it’s so hard to keep up with the research, that doctors should do what they are for taking people from sickness to lack of it, for everything else you should go to trainers /nutritionists etc. the system should pay the others in same amount like doctors, and have them integrated in a cooperative system.
quite accurate, appeciate it. Especially that you name the nonsense of overnight measurement. around @6:0 you describe that a very regular heart beat derives from a high activity of the symapthikus branch. This is incomplete. Low HRV can be caused by several configurations of the *relative* activation of one branch over the other. You will also see a very low HRV in a *completely* relaxed state or in meditation. Or if the general activity of both branches are low, such as in high age. IMHO, the HRV should no be used independent of the difference of the RHR to its minimum value, that is, a normalization should be used. Now, the balance between the two branches of the ANS is influenced *and* also expresses the adaptability. Thus, a biologically meaningful measurement, which would reflect the healthiness of the ANS control systems, would record the HRV values at different times during the day, always standardized, howeve, just as you mentioned. Imagine that in the morning the HRV (sdnn) is at a high value of lets say 50 ms, while during the whole day it is less than 5 ms. That would be very bad, and much more indicative than the values from the standardized measuement in the morning
Great summary of HRV related themes. I use HRV training for increasing my energy. It's a daily practice. What I'm looking for is an actual app, which can measure instant HRV at the same base, like my very old Polar RS800CX does. With the H10 belt from polar it should be possible to gain realtime measurements on an app.
Which HRV is listed in the table at 41:30? RMSSD? SDRR? I measure the RMSSD and SDRR every morning with my garmin, RMSSD is between 50 and 70 SDRR is between 80 and 140.
Interesting approach to integrating a chest strap with your solution. However, I’m curious about the decision to require a proprietary strap. Apps like HRV4Training offer compatibility with industry-standard straps like Polar, broadening their user base. Have you considered the potential benefits of adopting a similar model to cater to a wider audience? This could enhance user convenience and potentially increase market reach.
Based on the lion example, you could boil it down to: "high HRV means your body is in a restful state, low HRV means your body is in a more stressed state." Then why do people talk about HRV showing the balance between the two? If it's balanced, your HRV will be between your low and high HRV numbers?
It is odd with me. 42 M hrv average nightly 23-25 during the day 30-35 I eat 30 or less total carbs and I workout and seeing improvements every day with only Monday Wednesday and Friday being heavy and I cannot for the life of me raise it and I've been working on it for a couple of months.
The other downside is they measure it on the finger and wrist rather than a strap around the chest which is more accurate. Plus less regular measurement of it with only averages over the day and night
I hope I didn't drift off in thought while it was covered but my HRV is consistently 8-10ms nightly. This week my HRV isn't registering while RHR and BR are working fine. So I had a family member wear it to bed. Works fine for them and their HRV reads 45ms. I try I again and again, it isn't registering. Could that be because it dipped below 8ms? Because my fitbit is working in every other aspect.
@@jskweres2 I'd use it whenever you like really. It can get you in a more relaxed /restful state so could help with sleep but could be beneficial at any time of day. Regarding HRV it will vary day to day and by time of day. It's probably better to take a reading first thing AM and look at trends in average HRV month to month. It will change with overall health (i.e. depending on fitness levels, diet, stress etc). So deep breathing can help with reducing stress but you need to look at overall health to really get the most change and most benefit to your health
Hey, tanks for the informative Presentation. I am just starting to learn all about HRV and I was wondering if there is a specific reason you did not mention Elite HRV as an app. Since man researchers seem to use this app I thought it must be quite reliabe. Cheers
Probably not, but even if it is ms it might be using a different calculation than your Oura ring. Your Oura ring also may not be accurate or consistent in its measurements.
So, bottom line: HRV is hard to measure, not comparable between individuals and between measuring devices, correlates with many factors at once. All these are the typical features of a VERY bad KPI.
Amazing video ! I'm very curious when comes to average population (40-60 years old) who trains 2-4 times per week What's better for health and staying fit 2-3 slow sessions of cardio per week or maybe 1 more hit style and 1 slow and steady ?
Your info was very informative. I've done WHOOP for a year now and have an average of 51 HRV and 46 RHR. I'm 68 and have been a fitness junkie since I was 15. When I competed during college and until my early 40's my RHR was around 40. So it has increased somewhat as I've aged. How does that fit in with the heart rate declining as you age?
When you were competing I'm sure you were training more and your aerobic fitness was higher. This caused your resting HR to be lower. As you've aged, you've probably trained a bit less and your recovery is likely a bit slower. This makes resting HR increase as aerobic fitness declines slightly. As you age, your overall resting HR decreases and HRV does as well, but of course training can significantly influence both.
@@coachjoeljamieson No question that recovery is a lot slower. But I've been lucky, since I retired I've been able to maintain about 20 hrs/week cycling. Just not able to train at the same intensity any more.
@@jayobannon5359 That's the unfortunate thing about age, it slows everything down. Your 20 hrs/week is no doubt keeping your HRV higher than averages for your age group.
Joel, I’m interested in HRV for overall health. I have arrhythmia that causes random very high heart rates which I feel is producing a false higher HRV. My apps keep saying my HRV is good when it’s really low due to the spikes in heart rate. How can I get a real HRV result when I get these random rates?
High heart rates will produce low HRV, not false higher HRV. There are a lot of different types of arrhythmias so I can't say exactly how yours is impacting your HRV. Also, each app processes the data differently, so I can't say about what the apps are saying vs. reality. A good HRV app like Morpheus, the own I made, will compare your own data over time. This makes it much easier to get accurate results
It is about Breathing all throughout. HRV is one crucial part of it especially for the mental state. OXYGEN ADVANTAGE is a functional Breath Training tailored for Athletes. Buteyko Method for Athletes. Functional Breathing, not just breathwork. It works - I did it - it is amazing! Should be basic of any training! Adjusting the training to the breathing not what we so many do - huffing along through the mouth. Ruining HRV :( Exactly what happens he talks here about.

Elite HRV works fine with H10
Good stuff. Thanks for sharing
man my hrv is around 40 and im 30 years old. im 5'11 176 lbs, and im an active mountain biker and hvac tech. i dont get it.

My HRV is off the bottom of these charts. It’s always under 18😢
What is Oura and whoop doing incorrectly for them to not make your recommendations out of curiosity
Oura just measures the values overnight right? He said that those measurements aren't as accurate or consistent
The other downside is they measure it on the finger and wrist rather than a strap around the chest which is more accurate. Plus less regular measurement of it with only averages over the day and night

Because my fitbit is working in every other aspect.
My nightly fitbit HRV is 39.2 (up from 26.7 a month ago. I'm 45, is there a tool or coach that will help me increase my HRV to 60 (ideally ~114)?
Slow breathing (around 6 breaths a minute) can stimulate vagus nerve and increase parasympathetic activity.
@@chrisdturner would I do this right before going to bed? Or multiple times a day for 10 min to see my HRV increase?

Better than me. My nightly HRV is 27 and I’m 24.
@@BimmerWon do you drink coffee in the afternoon? I used to and that drove down my HRV to low 20s like yours
What kind of heart monitor strap do these apps use?
My HRV ON my Fitbit is under 20, I workout daily and do intermittent fasting

he did. said not accurate and stole some intellectual property.
The hrv shown at 17:00 , the averages, are in milliseconds right? my oura says i'm around 15ms on average at night, am i gonna die or something :')
No, the averages shown are not in milliseconds
Probably not, but even if it is ms it might be using a different calculation than your Oura ring. Your Oura ring also may not be accurate or consistent in its measurements.
So, bottom line: HRV is hard to measure, not comparable between individuals and between measuring devices, correlates with many factors at once. All these are the typical features of a VERY bad KPI.

The thing is you never say when to measure. Also you never discuss HRV training. Breathing in one's resonance frequency forces the HRV to increase.
