Body measurement features:
Manual target zone – bpm / % - 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%).
HRmax (user set)
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).
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 OwnCode® (5kHz) – 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 prevents interference from other training computers.
Polar OwnCal® – Smart Calories - The most accurate calorie counter on the market calculates the number of calories burned. Calculation is based on your individual data: your weight, height, age, gender and the intensity of physical activity. Smart Calories are available in heart rate monitors and activity trackers.
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.
Average and maximum heart rate of each lap
Average and maximum heart rate of training
Automatic age-based target zone – bpm / % - 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.
Heart rate – bpm / % - 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.
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).
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.
Interval trainer guided workouts – heart rate / pace / distance - Create interval workouts based on time, heart rate, speed/pace or distance and get guidance during training.
HeartTouch – button-free operation of wrist unit - When HeartTouch is on, different training information during training can be accessed without pressing buttons, for instance, when gloves make pressing buttons difficult, by bringing your training computer close to your transmitter.
Display zoom - Display zoom feature allows you to zoom in information on the display during training.
Number of laps – 99
Graphical target zone indicator - With this feature you can set your training computer to take laps based on preset distance, for example, every 1 km/mi. Depending on a product you can set also time or location based laps.
Automatic lap recording - With this feature you can set your training computer to take laps based on preset distance, for example, every 1 km/mi. Depending on a product you can set also time or location based laps.
Time and distance based interval timers - Use timers, for example, as a training tool in interval training to tell you when to switch from a harder to a lighter period and vice versa. The timers can be time- or distance- based.
ZonePointer - ZonePointer is a visible and moving symbol on the training computer display indicating whether you are inside the pre-set or desired target zone. This feature helps you to reach the desired intensity/pace/speed/cadence targets.
User configurable displays – two lines - This feature allows you to configure training computer displays to show the information that you need during your training session. Configure the displays either in the training computer or in ProTrainer 5 software.
ZoneLock - ZoneLock feature helps you to accumulate certain intensity. You can either lock a zone before a training session or during it by pressing a button when you are on the desired zone.
Totals - Totals includes your training data starting from the last reset enabling you to follow your long-term training.
Training files (with summaries) – 16
Weekly history - Weekly history gathers your weekly training data. By selecting a week, you can review your training data for the week.
Training Load - This feature is available in Polar software. When you transfer training results from your training computer to polarpersonaltrainer.com, you can follow your training load and recovery in the training diary. Continuous monitoring of training load and recovery will help you recognize personal limits, avoid over- or undertraining, and adjust training intensity and duration according to your daily and weekly targets.
Training diary - Diary is available in Polar software. When you transfer training results from your training computer to your Diary, you can easily follow up your training as well as plan your future training sessions. You can choose to see your training sessions in a Month or Week view, along with a Month or Week summary.
Training programs - The polarpersonaltrainer.com web service offers training programs for running, cycling, outdoor sports, and general fitness, for instance. The training program creates training targets which appear in your Diary. You can customize the program according your current fitness level.
