Garmin Connect App Tracks HRV – Heart Rate Variability

Due to the large number of devices on the market, we are unable to test them all for accuracy and compatibility.

If you are not sure about the above information, your devices manufacturer should easily be able to tell you if their device meets the criteria for compatibility. If they cant, then we would recommend not doing business with them. Look for the contact form on your device manufacturers website. Here is how to find out if your device is compatible:

Phone or Tablet Send a message to your phone or tablets manufacturer asking, Does this device receive Bluetooth 4.0 signals? make sure to tell them what device and version you have.

Heart Rate Monitor Send a message to your heart rate monitors manufacturer asking, Does this heart rate monitor capture accurate RR intervals? If so, does it alter or smooth the R-R intervals in any way? Also, does it have Bluetooth 4.0 capability? make sure to tell them what heart rate monitor you have.

Which Garmin Watches Measure Heart Rate Variability

Asked By : Trinidad Rosenbarger

There are a handful of newer Garmin watches that do provide raw HRV data. The most recent crop of Garmin smartwatches does provide access to raw HRV data. This includes the Epix series, Fenix 7 series, Forerunner 945 LTE, Venu 2 and Venu 2 Plus. If you have one of these, youre in luck.

Resting Heart Rate And Maximum Heart Rate

RHR and HRmax are essentially the lower and upper limits of your HR. They are both important for various reasons. However, despite some similarities, each needs to be considered separately.

Your RHR changes from day to day. The RHR of normal adults can vary anywhere between 60 and 100 bpm, and some athletes can see an even lower range than that. Typically, a lower RHR reflects good cardiorespiratory fitness levels , adequate sleep, low stress and abstention from stimulants such as alcohol and tobacco.

Garmin wearables typically measure RHR while you are asleep, usually not long before you wake up. Consider sleeping with your watch for the most accurate measurements of your RHR.

Your HRmax is the fastest your heart can beat. Unlike RHR, your HRmax doesnt change from one day to the next. It is also almost entirely unaffected by your fitness level, so getting into great shape wont increase your HRmax.

Everyones physiology is unique, and that includes your heart. Some naturally beat a bit faster than others, and some are a bit slower. As a rule, however, your HRmax will decline as you get older. This insight is widely used to estimate an individuals HRmax with help from the following formula: 220 age = HRmax bpm3. If you know your own true HRmax, you can enter it on your watch or in the Garmin Connect app.

But what if you have one of the older watches? You dont have the option to do a Health Snapshot. And doing the above mentioned HRV Stress Test will not get you raw HRV data. Instead, you get a score. Plus you need a heart rate chest strap to do the test.

Unless Garmin updates its older watches to be able to do a Health Snapshot you are out of native options. But you can resort to a third-party option an app called HR Variability.

  • First youll need to download the app and install it to your watch. This is done via the smartphone app.
  • Open Garmin Connect, click on the picture of your wearable along the top. This will take you through to the Settings page.
  • Tap on Activities & App Management. Choose Activities & Apps.
  • Do a search for an app called HR Variability. Install it and make sure to sync Garmin Connect to your watch.
  • The app is compatible with most Forerunner watches, the Fenix range and Vivoactives.

    Once installed you can go to your watch and make it one of your favorites. That way it wont require too many button presses to launch.

    To start a HRV measurement simply start the activity as you would any other activity such as a run or a swim. The app will ask you to specify whether the measurement is After Waking Up, Before Bed, After Exercising, Before Exercising or Else. Youll then have the option to choose between a 3 minute or 5 minute test. The app will remind you to remain still during the measurement.

    Starting From Maximum Heart Rate


    Your maximum heart rate is relatively stable and declines slowly as you get older. This is different from your resting heart rate, which reflects changes in fitness, recovery status and dietary choices.

    If you already know your maximum heart rate, simply enter your maximum heart rate in the user profile settings of your device or in the Garmin Connect app. If you dont know your maximum heart rate, it will be automatically estimated by using the common formula of 220 minus your current age.

    This formula for estimating maximum heart rate is utilized in guidelines from the American Society of Sports Medicine, which notes that while more complicated formulas exist, alternatives have not proven to be universally more reliable in practical usage4. According to this method, a 42-year-old person would have an estimated maximum heart rate of 178 bpm . Your maximum heart rate is likely within +/-12 bpm of this estimated value.

    Estimating your maximum heart rate is a good place to start. However, knowing your own maximum heart rate and using it to personalize your heart rate zones unlocks the full potential of this training tool.

    A variety of test protocols exist to determine your own personal maximum heart rate. You may also encounter your personal maximum heart rate during especially vigorous workouts that include sustained maximum-intensity efforts or during 5K/10K race events.

    Watches With Hrv Recording

    There are a number of watches that will record HRV, or more accurately, will record the beat-to-beat time for later HRV analysis.

    • Recent Garmin Watches. require you to download that you copy onto the watch. You must connect the watch to a computer and copy the file to the folder “GARMIN\NEWFILES”, which on Windows may require you to show hidden folders. Simply disconnect and the watch will restart, processing the FIT file. You can disable HRV with this file The watches include Garmin Epix, Garmin 920XT, Garmin 620, Garmin 235, Garmin Fenix 3, Garmin 920XT.

    Using Heart Rate Zones

    Heart rate zones offer insight into the current intensity of your performance. To anticipate the fitness or performance benefits of a workout, you should consider the combination of intensity, duration, recovery and repetition. This is true for specific workouts and within the broader picture of your training plan.

    Heart rate zones remove the guesswork from the intensity element of that formula.

    How Hrv Is Recorded

    Understanding Stress Level tracking on your Garmin Garmin® Retail Training

    Using heart rate variability in your day-to-day life is not simple, though. Your HRV readings will change throughout the day, even if theres no obvious stimulus to bring about such changes. And it will naturally be affected by stress and exercise, wherein your sympathetic nervous system grabs the wheel and causes your heart rate to rise.

    Results will also vary between people, not solely linked to obvious factors like fitness, so you should really only compare your own results over time. Dont fall into the trap of being jealous of your friends video game-style high scores.

    Garmin uses it to feed into training recommendations, for example. It gives you insight to make a clearer decision on how hard you want to go on your training. HRV Status feeds into the other metrics like training status, suggested workouts for even better feedback and guidance, Garmin told us.

    However, when we measure HRV we are also not interested in the rate of change of your heart rate during exercise look to a metric like VO2 Max for that. Instead, HRV is typically recorded when there is no obvious stimulus that is going to skew the results, such as when you are asleep.

    There are reasons your resting heart rate and estimated VO2 Max are typically more useful, and easier to understand, than metrics for the average person just looking to stay healthy. However, we are starting to see HRV scores given greater prominence in fitness tracker apps.

    What Is Heart Rate Variability

    Heart rate variability is a physiological phenomenon that can be recorded, analyzed, and interpreted to help understand how your body is navigating the challenges of life and environment.

    Specifically, HRV refers to the ever-changing length of time between consecutive heartbeats. When your heart is beating at 60 beats per minute, the beats are not evenly spaced one second apart. Look closely and you will see that some beats are slightly less than one second apart and others are a little bit more than one second apart. This irregularity is perfectly normal and healthy.

    These slight changes between heartbeats can be easily documented with an accurate recording device and are typically measured in milliseconds. Without physiological knowledge and analytic methods, however, the HRV phenomenon would simply be a list of numbers.

    Statistical analysis can reveal meaningful patterns in large amounts of data. RMSSD is a standard statistical measure of HRV. It represents the root mean square of successive differences between normal heartbeats for a given set of heartbeat data. This way of looking at HRV data is widely used by physiologists and exercise scientists to investigate topics like the impact of training loads and recovery processes.

    Luckily, you do not need to be an expert in physiology or statistical analysis to benefit from HRV-based insight. A wealth of information exists on the subject, however, if you do want to explore further.

    The Benefits Of Tracking Hrv

    Why is it useful to measure or monitor it? Well, for fitness particularly, it’s a way of knowing when you’re putting too much stress or strain on your body and can be an indicator of whether you’re physically and mentally ready to work out again.

    So if you’re a runner and you’ve just put in a tough 2-hour run, it’ll be able to help you decide whether you’re ready to go again the following day or whether you should take the day off from training. When you’re working out, your HRV decreases as you heart rate and exercise intensity rises.

    But it’s not just about serious athletes, as HRV measurements have started to trickle down into devices like fitness trackers where it can also be used to check in on how stressed you are.

    What is a normal, high or low HRV?

    So what does is mean to have a low or high HRV reading? There’s no ideal HRV score, and like resting heart rate, it’s hugely personal.

    But generally speaking, high HRV as being associated with healthy longevity and the side of the nervous system that promotes relaxation, digestion, sleep and recovery.

    A low HRV reading is commonly associated with stress, overtraining, inflammation and illness. Diabetes, coronary heart disease and high cholesterol are things commonly tied to having a low HRV as well.

    What is a high, low or normal HRV reading? A blog post on that subject by Oura, makers of the Oura Ring smart ring, which measures HRV during sleep to assess your readiness, offers an explanation:

    How Garmin Detects Your Hearts Activity

    Devices that offer all-day health insights based on heart monitoring data rely on the Garmin Elevate heart rate technology sensor, an optical sensor built into the back of the device. It detects your heart rate by shining a green light through your skin, which is reflected by the red cells in your skins blood vessels.

    When your heart beats, the muscular contraction of the heart itself pushes a rush of blood through your circulatory system. The cycles of this pulsing blood flow are your heart rate, or pulse, and can be detected throughout your body. Your Garmin watch conveniently measures your heart rate at the wrist.

    The other option for measuring heart rate is to pair a compatible heart rate strap with your smartwatch. A heart rate strap measures the electrical signals that fire in your heart as it beats. However, this method is typically only used during recorded activities . Wearing an elastic strap around your chest isnt practical for round-the-clock monitoring, but these heart rate straps can provide reliable data even during the most vigorous, high-intensity physical activity.

    Interpreting Hrv And Why Your Personal Baseline Matters

    Garmin Fenix 6 to Get Some New FR955 Features! Quick Overview!

    You will be able to see your average HRV and overnight trends as soon as you start using your device. Simply wear your device to bed and the analysis automatically occurs. What you will missing at first is meaningful context for interpreting your results.

    When it comes to making sense of any HRV metric, everything starts from you. A normal, healthy degree of variability for you is not necessarily the same as for someone else. Some people have naturally higher ranges of variation while others tend to exhibit less variability. And that is not all, what is normal for you also changes over time.

    Your own personal history, then, is the single-most meaningful frame of reference for interpreting HRV data. Given this fact, documenting your personally normal range of HRV values is a necessary first step in making your HRV data actionable.

    This takes time. In practice, it means that you need to routinely wear your Garmin device overnight for around three weeks before HRV status becomes fully active. While three weeks is the minimum amount of time needed to gauge your personal baseline, the analysis can utilize a few months of data to strengthen and validate your baseline range when that amount of data is available.

    Key concept: Your HRV baseline is a range of values derived from your measurement history that represent a normal degree of variability for you personally. Your baseline is the lens through which future HRV measurements can be meaningfully interpreted.
