Features

Body measurement features

• Automatic age-based target zone - bpm / % / % HRR
  To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR). See also Maximal oxygen uptake (VO2max) and Manual target zone.
• Average and maximum heart rate of each lap
  Average, minimum and maximum heart rate of training
• Heart rate – bpm / % / % HRR
  Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute or as percentage of your maximum heart rate. Heart rate can also be expressed as a percentage of your heart rate reserve, meaning the difference between your resting heart rate and maximum heart rate (HRR = HRmax - HRrest). In Polar software or during strength training, heart rate can be displayed as a graphical trend.
• HR-based target zones with visual and audible alarm
  You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.
• HRmax (age-based)
  The highest number of heart beats per minute (bpm) during maximum physical exertion. For a rough estimate of your maximum heart rate, subtract your age from 220. HRmax is a useful tool for determining the intensity of training as intensity zones can be defined using HRmax. Some Polar products define maximum heart rate during the Polar Fitness Test, see also HRmax (Polar Fitness Test -based).
• HRmax (Polar Fitness test-based)
  Some Polar products predict your HRmax simultaneously with the Polar Fitness Test. This predicted HRmax value is more accurate than the age-based formula (220 minus age).
• Manual target zone – bpm / % / % HRR
  This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%).
• Polar Fitness Test
  Polar Fitness Test measures your aerobic fitness at rest in just five minutes. The result, Polar OwnIndex, evaluates your maximal oxygen uptake (VO2max). With the Polar Fitness Test you can measure your aerobic fitness by yourself, automatically and without any exertion. All you need is your training computer. The Polar Fitness Test is as accurate in predicting the VO2max as any sub maximal fitness test. The test is based on heart rate and heart rate variability at rest and personal information.
• Polar OwnCal® – calorie expenditure with altimeter calibration
  Polar OwnCal calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions. Some Polar products also estimate the fat-burning percentage (fat% on display), that is, kilocalories expended from fat during a workout which is expressed as a percentage of the total kilocalories burned.
• Polar OwnCode® (2.4 GHz W.I.N.D.) – coded transmission
  Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding significantly reduces interference from other training computers. The 2.4 GHz W.I.N.D transmission is disturbance-free from other electronic devices.
• Polar OwnOptimizer – personal training status
  Polar OwnOptimizer feature is an easy and reliable test to determine whether your training is optimally developing your performance. OwnOptimizer helps you to optimize your training load during a training program so that you experience an increase in performance and do not undertrain or overtrain in the long run. Based on the test, you are provided with a scale and description of your personal training status.
• Polar OwnZone® – personal heart rate zone
  Polar OwnZone® determines your personal heart rate limits for a training session. Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment.
• Polar sport zones
  Polar sport zones provide an easy way to select and monitor the intensity of your training and to follow sport zones based training programs. Training is divided into five zones based on percentages of your maximum heart rate: very light (50-60%HRmax), light (60-70%HRmax), moderate (70-80%HRmax), hard (80-90%HRmax) and maximum (90-100%HRmax).
• R-R Intervals / Online HR Variability
  R-R Intervals / Online HR Variability feature measures your heartbeat intervals and reflects autonomic nervous system activity in heart beat regulation. The R-R interval measurement is most useful at rest and at low intensities. Relaxation rate indicates the state of your physical recovery.
• Relaxation rate during training
  Relaxation rate measurement is based on the heart rate variability, which indicates your autonomic nervous system's state. The degree of heart rate variability is highly individual and tends to decrease over time. Mental stress typically increases heart rate and decreases relaxation rate.

Altimeter and barometer features

• Altitude with graphical trend – available via Polar ProTrainer 5 software
  Altitude is measured with an atmospheric air pressure sensor. Altitude is shown as ascended and descended meters/feet and uphill/downhill steepness in percentages and grades.
• Altitude, ascent and descent – meters, degrees, percentage
  Altitude is measured with an atmospheric air pressure sensor. Altitude is shown as ascended and descended meters/feet and uphill/downhill steepness in percentages and grades.
• Temperature

G3 GPS features

• Cycling Limits
  This feature is useful for maintaining a certain level of intensity in your training. You can set upper and lower limits for heart rate, cadence, speed or power output. The training computer gives audible and visual alarms if your cycling rate goes out of the preset range.
• Distance based interval
  
• Distance based recovery measurement
• Distance – training, lap, trip and total
• Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.
• Incline Measurement
  Incline measurement tells you the uphill or downhill inclination in numerical form, helping you to adjust cycling effort accordingly. The feature shows you the uphill/downhill steepness in percentages and grades.
• Route mapping – opt. with ProTrainer 5 software
  Your training computer stores your route data during training with GPS sensor and enables you to download route information to computer after the training session. Routes are shown in ProTrainer 5 software and can also be easily exported to other mapping and positioning software such as Google Earth.
• Running Index
  Running Index is based on heart rate and speed data measured during the run. It gives daily information about your performance level, both aerobic fitness and running economy. Improvement in running efficiency indicates improved economy of running performance.
• Speed-based target zones with visual and audible alarm
  You can define your target zones for a training session based on speed. When you are out of the preset zones, the training computer will give a visual and audible alarm.
• Speed/Pace – current, average and maximum
  Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor. Pace (expressed as min/km or min/mile) stands for the rate of speed. Pace is usually used in running. By setting a target pace, you can follow how fast you need to run in order to reach a certain distance in a predefined time.
• SpeedPointer
  SpeedPointer feature tells you your speed within set speed limits.

Recording features

• Combined training files
  This feature allows combining consecutive training sessions. When you start a new training session within an hour of the previous one, you can combine the new session with the previous one.
• Memory left indication
• R-R Recording
  R-R recording rate saves heartbeat intervals, that is, intervals between successive heartbeats. This information is also shown as instantaneous heart rate in beats per minute in recorded samples. This enables the analysis of heart rate variability (HRV) using the ProTrainer 5 software with an accuracy of 1 ms.
• Totals
  Totals includes your training data starting from the last reset enabling you to follow your long-term training.
• Training files (with summaries) – 99
