Heart Rate Based Features

Your heart rate is a good measure of exercise intensity. Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying these principles.

You can set your heart rate zones based on your maximum heart rate.

There are also several heart rate related features available in the default widget loop.

Your current heart rate in beats per minute (bpm). The widget also
displays a graph of your heart rate for the last four hours,
highlighting your highest and lowest heart rate.

Your current stress level. The device measures your heart rate
variability while you are inactive to estimate your stress level

Your current Body Battery™ energy level. The device calculates
your current energy reserves based on sleep, stress, and activity

Your device analyzes your heart rate variability, stress level, sleep quality, and activity data to determine your overall Body Battery level. Like a gas gauge on a car, it indicates your amount of available reserve energy.

The HRM-Pro, HRM-Swim, and HRM-Tri heart rate accessories record and store your heart rate data while you are swimming.


The FR 745 measures several PHYSIOLOGICAL PARAMETERS. These performance measurements are estimates that can help you track and understand your training activities and race performances.

This is what makes the watch worthwhile.

  1. Daily Suggested Workouts
    • The watch will suggest you workouts based on your training status and VO2max.
  2. Functional Threshold Power
    • For cyclists, If you know your functional threshold power (FTP) value, you can enter it and allow the software to calculate your zones automatically.
  3. Heat & Altitude Acclimation
    • Environmental factors such as high temperature and altitude impact your training and performance. For example, high altitude training can have a positive impact on your fitness, but you may notice a temporary VO2 max. decline while exposed to high altitudes. Your Forerunner device provides acclimation notifications and corrections to your VO2 max.
  4. HRV Stress Test
    • Your HRV stress score is the result of a three-minute test performed while standing still, where the Forerunner device analyzes heart rate variability to determine your overall stress.
    • Training, sleep, nutrition, and general life stress all impact how you perform. The stress score range is 1 to 100, where 1 is a very low stress state, and 100 is a very high stress state. Knowing your stress score can help you.
  5. Lactate Threshold
    • Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream. In running, it is the estimated level of effort or pace. When a runner exceeds the threshold, fatigue starts to increase at an accelerating rate.
    • For experienced runners, the threshold occurs at approximately 90% of their maximum heart rate and between 10k and half-marathon race pace. For average runners, the lactate threshold often occurs well below 90% of maximum heart rate.
    • Knowing your lactate threshold can help you determine how hard to train or when to push yourself during a race.
  6. Performance Condition
    • As you complete your activity, such as running or cycling, the performance condition feature analyzes your pace, heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared to your average fitness level.
    • It is approximately your real-time percentage deviation from your baseline VO2 max. estimate.
  7. Predicted Race Times
    • Your device uses the VO2 max. estimate and your training history to provide a target race time based on your current state of fitness.
  8. Recovery Time
    • The recovery time displays how much time remains before you are fully recovered. It gives you an approximate time for your body to get completely fresh before a big race/event.
  9. Training Effect & Primary Benefit
    • Training Effect measures the impact of an activity on your aerobic and anaerobic fitness. It is determined by your user profile information and training history, and heart rate, duration, and intensity of your activity.
  10. Training Load & Focus
    • Training load is the sum of your excess post-exercise oxygen consumption (EPOC) over the last 7 days. EPOC is an estimate of how much energy it takes for your body to recover after exercise

  11. Training Status
    • These measurements are estimates that can help you track and understand your training activities. The measurements require a few activities using wrist-based heart rate or a compatible chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
      • Peaking
      • Productive
      • Maintaining
      • Recovery
      • Unproductive
      • Recovery
      • Unproductive
      • Detraining
      • Overreaching
      • No Status
  12. VO2 Max
    • VO2 max. is an indication of athletic performance and should increase as your level of fitness improves. The Forerunner device requires wrist-based heart rate or a compatible chest heart rate monitor to display your VO2 max. estimate. The device has separate VO2 max. estimates for running and cycling.
  13. Intensity Minutes
    • The device monitors your activity intensity and tracks your time spent participating in moderate to vigorous intensity activities.
    • Your Forerunner device calculates intensity minutes by comparing your heart rate data to your average resting heart rate
  14. Pulse Oximeter
    • We are all familiar with this sensor. In times of COVID-19 If a person has a mild case of COVID-19 and is self-treating at home, an oximeter can be a helpful tool for checking oxygen levels so that low oxygen levels can be caught early
    • The Forerunner 745 device has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood. Knowing your oxygen saturation can help you determine how your body is acclimating to high altitudes for alpine sport and expedition.

Sleep Tracking Data

While you are sleeping, the device automatically detects your sleep and monitors your movement during your normal sleep hours. Sleep statistics include total hours of sleep, sleep levels, and sleep movement.

Displays total sleep time, a sleep score, and sleep stage information for the previous night.

Track your sleep data throughout the week.

The Forerunner 745 device has a wrist-based pulse oximeter to gauge the peripheral saturation of oxygen in your blood. Knowing your oxygen saturation can help you determine how your body is acclimating to high altitudes for alpine sport and expedition.
