How to use HRV to optimize your recovery
Heart rate variability (HRV) is a helpful metric for endurance athletes. Read on to learn why there’s a buzz around it and how to use Suunto to track heart rate variability.
First, it is good to understand what Heart Rate Variability (HRV) is. As an example, when your heart rate is 60 beats per minute, each interval is not exactly one second. There’s a slight variation in the duration between the beats. HRV is a quantitative measure of the variation in the time intervals between consecutive heartbeats.
The interesting point with HRV is that it serves as an indicator of the balance within the autonomic nervous system and offers valuable insights into an individual's overall health and stress levels. More variation generally means the parasympathetic nervous system is doing its job as a regulator.
Various factors, such as heavy training, mental stress, or the presence of an illness like the flu, can influence HRV readings.
Suunto Race, Suunto Vertical and Suunto 9 Peak Pro GPS watches can track your HRV during your sleep. Nighttime measurement is a reliable and easy way to gather comparable HRV data. Continuous HRV monitoring allows for the calculation of the average Root Mean Square of Successive Differences (RMSSD) value, a commonly employed metric for quantifying HRV.
You can see the HRV data anytime as a mini widget in your watch and in the Suunto app’s Training zone.
Your recovery status is evaluated by comparing your 7-day average HRV with your normal range.
Interpreting HRV Data
Heart rate variability is highly individual. As said, higher HRV values generally indicate better autonomic balance, although the assessment should always be contextualized within an individual's normal range.
At Suunto, we define your normal range over a 60-day period and then compare your rolling seven-day average with that baseline. A minimum of 14 measurements needs to be gathered over the 60 days to define your normal range. For the seven-day average, a minimum of three measurements is needed. So, if you are new to measuring HRV with Suunto, you will have HRV data even after the first night, but the data will get more defined as more data is gathered.
By comparing the long-term values with short-term trend, you will get an understanding of load and stress you are putting on your body.
If your HRV values consistently fall below your normal range, it is an indication of a compromised recovery state. This could be caused by chronic stress, inadequate sleep, overtraining, or an underlying health condition.
It is normal that after a very hard effort or a race, your HRV drops below the normal range for a day or two.
If your HRV rises abnormally high (above a certain standard deviation) within a day or a few days, the app indicates with a yellow or red that you are likely experiencing abnormal amounts of recovery (parasympathetic nervous system activity). This is often in response to accumulated amounts of stress.
Suunto app visually represents your HRV recovery status as a bar indicator, offering insights into your recovery.
How to use HRV in daily training with Suunto
Suunto utilizes overnight measurements to capture HRV data. To obtain HRV measurements, it is necessary to wear the watch while sleeping and ensure that sleep-tracking functionality is activated.
Sync your watch regularly with the Suunto app to see the latest data.
Compare your HRV measurements with your training load. Look for patterns and relationships between your HRV values and the intensity or volume of your workouts. This can help identify how your body responds to different training stimuli.
Compare your HRV values with your resting heart rate. Generally low resting heart rate and a high heart rate variability are good indicators of sufficient recovery.
If your HRV readings indicate a decrease or significant deviation from your baseline, it may suggest a higher level of physiological stress or insufficient recovery. Consider modifying your training plan by reducing the intensity or volume of your workouts to allow for adequate recovery.
Use HRV as a guide to schedule regular recovery days or lighter training sessions when your HRV values indicate a need for more rest.
Remember that HRV can vary between individuals, so it is essential to understand your own personal baseline and response to training. It's important to note that with HRV it's good to look at other factors that impact recovery state such as training stress balance, sleep volume and changes in feeling.
Heart rate variability measurement is available in Suunto Vertical, Suunto Race and Suunto 9 Peak Pro GPS watches.

Get feedback from the Suunto coach
The role of a coach is to provide guidance, support, and expertise to help athletes achieve their goals. A coach can be crucial for monitoring progress and providing feedback and adjustments as needed to ensure the athlete is training safely and effectively.
A great coach is also a friend and a companion in your journey. A coach motivates you and requires accountability. Overall, a coach helps athletes improve their performance, avoid injury, and reach their full potential. This is also our goal when providing you with Suunto Coach.
Suunto app’s Training zone has an AI-based coach that is an integral part of the service. It looks at hundreds of different parameters after each workout, learns how you train, and builds a normal training pattern that evolves from every workout you do. Based on this, it can give you the key highlights of your training, recovery, and progress. It provides insights and suggestions for the current week, so you can adjust your effort level as you go forward.
The Suunto coach recognizes areas you are missing in your training this week that you normally are focusing on: Are you lacking volume in your swim workout? Do you push yourself too much with high-intensity runs?
The Suunto coach is not trying to push your training in a direction that you are not used to. For example, if you usually do just high-intensity training, the Suunto coach is not going to ask you to focus more on lower-intensity sessions.
Suunto coach doesn’t really know what is your goal or if you want to follow some specific training methodology. But what it does, is alert, highlight, and comment when you are exceeding healthy limits or just lacking some training aspects you are used to. Suunto coach is there to keep you on your selected path. Its recommendations and highlights are easy to digest without you needing to dig deep into the data.
Now, go to the Suunto app and meet your new coach – the coach already knows you based on your training history!

Manage your training with Suunto app’s Training zone
Get a detailed overview of your training in Suunto app’s new Training Zone!
A progressive training load with adequate recovery and ways to follow progress will lead to a successful adventure or race.
Suunto is your daily companion to enhance your performance. The new training toolset in Suunto app’s Training zone is vast. Read on and learn what’s available. We are sure you will find your new favorite dataset to analyze your training and follow your progress.
To ensure you have the latest Suunto app version update your iOS app in App Store and Android app in Google Play.
Four new ways to look at your training
Am I training smartly? Is my training load progressive? Do I have the right intensity mix? What type of impact do my workouts have?
Training load
The training load theme in Suunto app’s Training zone gives you a good overview of this week’s training load compared to a six-week average. You will also see the daily training load split and the split by activity type. All of this will help you understand your overall physiological load and how much more you can – and should – still do this week.
The value of following your physical load weekly with comparisons to your long-term baseline is that you can look at this as a goal for the week. To gain some fitness, you might want to slightly increase the load for the week. To ensure recovery, keep the load level lower than your average.
Training intensity
Are you really doing both easy base training and higher intensity? Or is your training piling up in a single intensity zone, like tempo work in zone 3? The new Training intensity theme in Suunto app will help you understand your training better as you will see both the weekly intensity distribution and the six-week averages.
The workout intensity totals can be viewed as heart rate, pace, running power, and cycling power zones.
You can set your sport-specific training zones in your Suunto watch based on heart rate, pace and power. Suunto is following a five-zone model where your anaerobic threshold is at zone 4 /5 limit. You can find your correct training zones with a lab or a field test. SuuntoPlus Sports apps like the Anaerobic threshold test and the Functional threshold power test will guide you through a field test session.
Learn more about intensity zones.
Training volume
The sports you have done during the week are shown with duration, distance, load, and ascent. Sports are also grouped to give an overview of each type of sport i.e. running includes running, treadmill, and trail running.
Volume is compared with your six-week average.
As you follow your training volume, you can now easily ensure that you meet the numbers for your key sports any given week: It might be that as a trail runner, you want to get 3000 meters of ascent each week, or as a cyclist, ride 200 kilometers weekly. Your six-week average will help you match your personal benchmark.
Training impact
Suunto app’s Training impact is a new tool that helps you understand your training model and the physiological systems you are targeting. This will help you understand if you are doing what you were planning to do – and if you are missing something in your training.
Training impacts are defined as cardio and muscular impacts. Each workout gets assigned an impact such as “Aerobic” or “Speed & Agility”. Cardio impacts are based on workouts intensity, load, and duration. Muscle impacts are based on activity type.
The training model is identified based on your workout intensity distribution such as Polarized (most activities on low and high intensities, less in the middle), Sweet spot (training mainly between aerobic and anaerobic thresholds), and Base training (most workouts are in zones 1&2).
In addition to the current week, you will see the six-week average for your training impact.
As with other training insights, the impacts are illustrated with long-term reference. If your normal training week has two aerobic sessions, one VO2 max session and two strength sessions, and on Friday you are still missing those aerobic sessions, you know what to focus on during the weekend. This will help you check all the boxes.
Training impact is currently available on Suunto app for Android. Coming soon to iOS as well!
