How To Use A Heart Rate Variability Monitor
Thanks to technological advancements, you no longer need a specialized laboratory or a medical professional to measure and analyze your heart rate variability data. A quality heart rate monitor, such as the Polar Vantage V2, will provide all the HRV tracker information you need alongside information about your calories, sleep, heart rate, and other data related to your workout.
To get the most accurate Polar HRV reading possible, youll also need a heart rate strap and the Polar Flow app. With these HRV testing tools, your data can be measured by completing an Orthostatic Test on your Polar device.
Using a HRV monitor will detect any changes in your autonomic nervous system by calculating your heart rate, heart rate variability, and sleep quality, while also factoring in things like stress levels and environmental changes. Once analyzed, your data will be displayed on the Polar Flow app for you to keep track of.
Since heart rate variability data can be sensitive, its best to conduct the test regularly at the same time of day. Taking the test first thing in the morning is generally recommended for this reason, and can be a good way to gauge how recovered you are before the day begins.
Target Heart Rates Chart
What should your heart rate be when working out, and how can you keep track of it? Our simple chart will help keep you in the target training zone, whether you want to lose weight or just maximize your workout. Find out what normal resting and maximum heart rates are for your age and how exercise intensity and other factors affect heart rate.
Is My Heart Rate Variability Something That Should Make Me Worry
In general, an abnormal heart rate variability isnt something that will cause a medical emergency, but it can be a sign of current health problems or issues down the road. Its also important to remember that most consumer-level devices that track heart rate variability are not as sensitive as an EKG.
Its important to keep in mind that your heart rhythm is incredibly complex. While you can find devices and apps that track your heart rate variability, a healthcare provider is the most qualified to look at your heart rate and advise you on what you can and should do about it.

Heart Rate Variability Has Natural Highs And Lows
Some explanations of HRV oversimplify it by asserting that a high number is always good and a low one is always bad. Its far more complex.
While high HRV is generally positive, there are situations where low HRV is necessary and even desirable. For example, during strenuous exercise, low HRV is a reflection of your fight-or-flight system appropriately dominating to get your heart rate up for activity. Your HRV will rebound afterwards, as your rest-and-digest system takes over to help you recover.
These fluctuations occur throughout the day, as different daily stressors continuously challenge your system. Simply being excited, or moving from the couch to the bathroom, can change your HRV at any given moment.
At night, your body is in a consistent state, without any confounding variables . Some wearables take the apples to apples approach when it comes to your measurements. They fail to caveat that daytime measurements might mask your underlying ANS balance.
Is Resting Heart Rate Different By Age
For most of us , between 60 and 100 beats per minute is normal.1 The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now thats chill!
When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness and higher blood pressure and body weight.2

Median Hrv Across Oura Members By Age And Gender
Below, well see the range of HRV scores across Oura members by age and gender.
As this chart shows, the general takeaway is that HRV is much higher for younger people than older people. Multiple, population-based research studies confirm that HRV tends to decline with age. Some research suggests that this decline likely reflects the normal aging process.
Other studies show this decline in HRV may be less severe the healthier the person is. With the right lifestyle and genes, there can be a lower reduction or higher values because they had a higher HRV over their lifespan, Altini explains.

Is It Better For Your Hrv To Be Low Or High
Low HRV may mean that your fight-or-flight response is dominating, leading to fewer variations between heartbeats. This may be triggered by negative situations, such as stress or lack of sleep. Low HRV may thus indicate poor health that can contribute to mental health problems such as depression and anxiety and even some cardiovascular diseases.
High HRV may occur when the relaxation response is more activated, resulting in decreased time between heartbeats. This may be seen when you are relaxed. In this state, you have more flexibility and resilience in switching between low and high heart rates. High HRV may thus indicate better cardiovascular health and the ability to cope better with stressful situations.
Measurement Of Heart Rate And Heart Rate Variability
We measured resting heart rate and heart rate variability from a 10-second, 12-lead ECG, recorded in the morning of the first enrolment visit to limit circadian variability. All ECGs were transmitted electronically for storage at the University of Glasgow ECG Core Laboratory based at Glasgow Royal Infirmary, Scotland, and interpreted using the same software.10
We computed the standard deviation of normal-to-normal RR intervals , one of the most frequently used and easily calculated indices of heart rate variability, by deriving it from normal-to-normal RR intervals.11 Normal-to-normal RR intervals were defined as the time between 2 successive normally conducted QRS complexes.

Understanding Normal Heart Rate Variability
Heart rate variability , which is regulated by your autonomic nervous system, is very useful for evaluating physical fitness and your bodys readiness to perform. Measured in milliseconds , HRV is literally the difference in time between beats of your heart.
If heart rate variability is something youre not already familiar with, check out our Ultimate Guide to HRV to better understand what it is and why its so meaningful.
Broadly speaking, higher HRV is usually an indication of better fitness. However, one of the most important things to realize with heart rate variability is that it is an extremely individualized metric that often differs significantly from one person to another. It can also fluctuate considerably on a day-to-day basis .
What Is A Good Hrv Score For Me
The average heart rate variability for all WHOOP members is 65 for men and 62 for women. For 25-year-olds its 78, for 35-year-olds its 60, for 45-year-olds its 48, and for 55-year-olds its 44. In general, people using WHOOP tend to be athletes and/or health-conscious individuals looking to perform better at whatever they do. If your HRV falls in line with the WHOOP averages, its reasonable to consider it good.
However, rather than comparing yourself to others and worrying about what is good or normal, its much more practical to follow your own HRV trends. If youre making efforts to better your overall health and fitness, over time you should see your heart rate variability begin to rise.

When To See A Doctor
If a higher heart rate is a result of being under stress or consuming a lot of alcohol or caffeine, thats not typically a cause for alarm. However, these situations still warrant a discussion with your clinician, as they can discuss with you how to best address any necessary lifestyle changes.
Meanwhile, adults without an acute condition that might cause an elevated heart rate may also want to contact their doctor if their resting heart rate remains above 100 beats per minute for a few days, says Dr. Tilahun.
If the heart rate is persistently elevated for more than a few days and there is absence of a clear thing that can explain it, that should be a time to talk to your doctor, he says.

How Do I Get My Heart Rate In The Target Zone
When you work out, are you doing too much or not enough? Theres a simple way to know: Your target heart rate helps you hit the bullseye so you can get max benefit from every step, swing and squat. Even if youre not a gym rat or elite athlete, knowing your heart rate can help you track your health and fitness level.
Analysis Of Holter Tapes
Tapes were recorded on Del Mar Avionics recorders and were processed by research technicians using a GE Marquette MARS 8000 Holter analyser using standard techniques. The scanner automatically detected and labelled each heartbeat . Automatically detected beats were over-read by the technicians and corrected if necessary. Undetected ectopic beats were inserted however, undetected normal beats were inserted as unclassified beats. Analyses were reviewed in detail by PKS. To be accepted for these analyses, recordings had to be in predominantly normal sinus rhythm with at least 18 h with 80% normal-to-normal intervals. Both T1 and T2 recordings needed to be acceptable. HRV and ectopy counts were calculated from beat-to-beat files exported to a Sun Enterprise 450 server using validated research software.

What Factors Influence Heart Rate Variability
- Physiological factors. Age, gender, genetic factors, and circadian rhythm can impact your heart rate and HRV.
- Lifestyle factors. These include diet, physical activity, stress, alcohol consumption, tobacco use, sleep, medications, etc.
- Diseases. Studies have shown that HRV is lower in people suffering from diseases such as:
What Do Hrv Numbers Mean
Heart rate variability is the difference in time between the beats of your heart, measured in milliseconds .
For the most part, younger people have higher HRV than older people, and males may have slightly higher HRV than females. Additionally, elite athletes tend to have greater heart rate variability than non-athletes. However, what represents a healthy HRV varies for everybody. There are many exceptionally fit people who have heart rate variability that is lower than the norm.
Below is a graphic that shows the average range of heart rate variability by age, from 20-65.

How To Improve Your Resting Heart Rate
You can lower your resting heart rate by improving your physical fitness and making some lifestyle changes.
Regular cardio exercise, like running, swimming, or biking, trains the heart to be more efficient over time. With each heartbeat, the “athletic heart” maintains its output of blood to the body at a lower heart rate.
In addition to exercise, other actions that may improve your resting heart rate include:

Population Comparison For Hrv Data
This research review covers ranges for HRV values for RMSSD, SDNN, HF/LF, and more based on published research. Below you will find similar values for Elite HRV app users with a primary focus on the Elite HRV score.
Keep in mind, the Elite HRV user base may not directly represent the general population. We have a higher representation of elite and recreational athletes that typically have higher HRV scores. This may slightly skew the sample stats when compared to some medical research studies. That said, we do have a very large population sample that helps increase the confidence of the data analysis. There is also a significant number of average health seekers and a number of people rehabilitating from serious injuries, illnesses, or diseases.

What Is The Average Hrv
Whats a good HRV for women? Whats a good HRV for men?
Trick question! Theres not an optimal HRV for men, women, or even a certain age group. HRV is a highly sensitive, individual metric that varies from person to person, and can change daily, or even hourly.
HRV is highly individual, so you should compare your HRV to your own averages over time to gain a sense of whats normal for you, says Marco Altini, an HRV expert, data scientist, and Oura advisor. Plus, keep in mind that its normal to see daily and seasonal fluctuations in your HRV.
The best way to determine your normal HRV level is to use a wearable, like the Oura Ring, that measures your HRV in a controlled setting, such as overnight as you sleep, and establishes a baseline over a few weeks. That said, based on community data, Oura data scientists have found a range of normal HRV scores across Oura members, and we can see interesting trends across age and gender.
Best Practice And Getting Started
To find out more about the benefits of training with HRV, go to start with this article.
It is important to bear in mind that a bit like body weight, HRV changes from day to day, and changes of 10% one way or the other are not unusual. Also, like body weight, the underlying trend matters, and a baseline calculated as a weekly seven-day rolling average will reveal these. When training, recovery and lifestyle are well matched, its remarkable how stable your HRV baseline becomes. Good HRV apps and software will measure the day-to-day variation and identify when daily changes become significant often by color-coding the variation against the standard deviation.
For best practice, here is a checklist to help you get the most out of HRV monitoring:
- Readings taken at the same time every day
- Use a validated sensor & app
- Keep to the same body position
Which Lifestyle Factors Impact Hrv
Your HRV decreases, or “worsens,” naturally as you age. Besides merely getting older, you may also notice a lowered HRV when you’re under a lot of stress, dehydrated, drinking a lot of alcohol, eating unhealthily, less physically active, and having poor sleep, says Dr. Mo.
The opposite can happen, too: Your HRV may increase when you start managing stress and improving your food choices, getting regular exercise, staying hydrated, drinking less alcohol, and sleeping for a solid seven to nine hours each night. As Dr. Mo points out, it’s possible for a 65-year-old who’s physically fit and active to have a higher HRV.
“They’ve seen that if people engage in these , they tend to trend toward having a better heart rate variability,” she says. “But they currently don’t really know the physiological basis for why that happens.”
Dr. Mo says it may be tied to the effect of these behaviors on the autonomic nervous system. Dr. Horwich agrees. “If someone is not eating healthfully, for example, that is the time your sympathetic nervous system may kick in, and when this is activated all the time, it’s not healthy for your body,” Dr. Horwich says.
