24/7 Activity Tracking
Tracks your daily activity at five intensity levels for 24 hours a day, seven days a week, and provides a complete picture of all of your activity. It counts your active time, daily burnt calories, steps, distance from steps and sleep.
It’s based on the analyses of the frequency, intensity and regularity of your movements together with your physical information.
Intensity levels are:
- Resting (sleep and rest, lying down)
- Sitting (sitting or other passive behavior)
- Low (standing work, light household chores)
- Medium (walking and other moderate activities)
- High (jogging, running and other intense activities)
You can also see how different activity intensities accumulate daily activity: the higher the intensity, the faster you’ll reach your activity goal. Find more examples for low, medium and high intensity activities in Polar Flow app and web service.
We need physical activity to stay healthy. The Activity Goal helps and motivates you to stay active all day long. Your device tells you your daily Activity Goal and guides you on how to reach it. It’s based on your personal details chosen level of activity and general health recommendations. The activity bar on your device fills up during the day based on the duration and intensity of your activity.
You can stay active at a moderate pace throughout the day or meet your goal faster with more intense activities. Your device helps you to reach your daily activity goal by giving practical guidance like ´walk for 50 minutes or jog for 20 minutes´. You can find more tips on how to reach your Activity Goal in the Polar Flow app and web service.
The foundation of Polar Activity Goal is in evidence-based physical activity guidelines which establish the minimal amount of physical activity needed to achieve important health benefits. The health benefits include healthy body weight, healthy bones, muscles and joints, psychological well-being, and reduced risk of certain diseases.
Includes the cumulative time you spend on your feet and on the move. In other words, low, medium and high intensity activities are considered Active Time. To get more active time, avoid sitting or break it up regularly with short walks.
Research has shown that both the reduced time spent inactive and breaks in inactivity have health associations. Replacing two hours of sitting per day by low intensity activity consumes calories equivalent to brisk walking for 30 minutes.
You can see the time spent on different intensity levels in the Polar Flow app and web service.
Steps and Distance
Your device counts your steps and the distance you walk during the day. Your steps are estimated based on the frequency, intensity and regularity of your wrist movements.
Stores all your daily physical activity. You can easily follow your daily and long-term physical activity in Polar Flow app and web service. The total active time is the cumulative time of body movements that are good for your body and health.
You will find detailed information in the Polar Flow app and web service, like time spent at different activity intensity levels, average of daily goal completion, calories burned and steps taken, amount of inactivity alerts and sleep time and quality.
Tracks all your active choices during the day and shows how they help you stay healthy. Strong scientific evidence exists on the numerous benefits of physical activity. Activity benefits include, e.g. heart health, muscle and bone health, stress reduction and sleep quality.
The Activity Benefit rewards you by giving you daily, weekly and monthly feedback, because the more regularly you move, the greater the health benefits. You can check up on how you're doing either from the Polar Flow app or web service.
Reminds you to get up and avoid sitting and standing still for too long – even on those days when you gain enough daily activity. Being inactive has a negative impact on your blood circulation, metabolism and energy expenditure.
After 55 minutes of being inactive your device gives you an Inactivity Alert which reminds you to add active breaks to your daily routines. If you continue being inactive for more than one hour, you will see an inactivity stamp in your daily activity data.
You won’t get any Inactivity alerts during night time.
Sleep Duration and Quality
Your training computer automatically tracks the duration of your sleep and shows in the Polar Flow app and web service how restful your sleep has been.
Most adults do very well with eight hours of sleep, but sleep needs may vary from about six to nine hours. Your sleep needs are affected by several factors like individual characteristics, training load, mental stress, body’s condition and possible sleep debt.
By following your sleeping patterns you can see if they’re affected by any changes in your daily life and find the right balance of rest, daily activity and training.
An assessment of sleep quality relies on your wrist movements. The periods when you sleep peacefully and don’t move a lot are calculated as restful sleep. The periods when you move and change your position are calculated as restless sleep.
Train for a running event with a personalized and adaptive running plan in Polar Flow. Choose one of four events, 5K, 10K, half marathon and marathon, and get a comprehensive training plan that fits you and your goals.
Depending on your choices and activity levels, you will receive a personal running program that can range from 9 to 15 weeks in length. Running Program also offers a base-building phase that can work for months before the start of the actual running plan.
Running Program gives you easy-to-follow instructions, motivational guidance and supportive exercises with video instructions that take the guesswork out of training.
During individual training sessions, compatible Polar products guide you in real-time. You can see your target heart rate zone and target duration and adjust your training for optimal results.
Heart rate (HR) is an excellent measure of exercise and your training intensity. In the human body heart rate is regulated to match the demands of the body and the environment. When exercise intensity increases, heart rate also increases to match the increased rate of energy expenditure and oxygen uptake.
Heart rate can be expressed as the absolute number of beats per minute (bpm) or as a percentage of your maximum heart rate (% HRmax) or heart rate reserve (% HRR). Absolute heart rate during training is not very informative on its own, but when it’s expressed and interpreted in relation to HRmax or HRR it determines individual exercise intensity.
Your heart rate value in beats per minute (e.g. 125 bpm) is individual and cannot be compared to another person's value. A percentage of your maximum heart rate value on the other hand is comparable. For instance your friend may have a higher heart rate value in bpm, but the percentage of your individual HRmax can be the same. This means that you have the same relative training intensity.
Maximum heart rate (HRmax) is the highest number of heart beats per minute (bpm) during physical exertion. HRmax is individual and may somewhat decrease as you age. It sets the individual reference value for your training intensity and is used in the calculation of the default heart rate zones and many Polar Smart Coaching features.
An age-based HRmax is a rough estimate of your maximum heart rate, and it is used as default in most Polar training computers. The most reliable and safest way to determine your HRmax is to have it measured in a maximal laboratory test.
Tells you in an easy way if the main effect of your training is fat burning or fitness improvement. EnergyPointer visually indicates the turning point between these two training effects.
Low intensity training has several health and performance benefits through increasing fat burning. Training in higher intensity improves cardiorespiratory fitness more effectively by, for example, strengthening your heart and increasing blood flow to muscles and lungs.
To calculate the EnergyPointer your training computer uses your heart rate and heart rate variability as well as your personal information including age, gender, height, weight, maximum heart rate and fitness level.
Calculates the number of calories burned based on your individual data: your weight, height, age, gender, HRmax, HRrest, VO2max, and the intensity of your training/activity.
Heart rate-based calorie calculation is used when heart rate is measured, and it measures burned calories the most accurately also in conditions like cycling or lifting weights. Activity-based calorie calculation is used in training computers and activity trackers, when heart rate is not available.
You can see the cumulative energy expenditure (in kilocalories, kcal) during exercise and total kilocalories of the session after exercise. You can also follow your total daily calories.
Helps you to understand how each training session benefits your fitness. It also gives you motivating feedback immediately after exercise. With the Training Benefit feature, you can make your training more varied by altering your training intensity and duration.
The Training Benefit feedback is based on exercise intensity and duration. It reads into how much time you spend and how many calories you burn in each intensity zone. You get a quick overview after each session and for more detailed feedback, you can either check your training file from your training computer or later in the Polar Flow app or web service.
