Maximum Performance for Endurance Sports
RS800CX Heart Rate Monitor is for multisport athletes who require a wide range
of performance information. The RS800CX measures detailed information about your
performance and helps avoid over or under training by aiding you to train at the
right intensity. The Polar Fitness test measures your aerobic fitness at rest
and tells you your progress. Comes with Polar ProTrainer 5 software for
analyzing, planning and keeping a training diary.
Altimeter and Barometer Features
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.
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.
age-based target zone - bpm / % / % HRR:
To help you train safely and effectively, the training computer automatically
determines your heart rate target zone limits 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), meaning the difference between your resting heart rate and
maximum heart rate (HRR = HRmax - HRrest). See also Manual target zone.
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 (bpm) or as a percentage (%) of your
maximum heart rate or as a percentage of your heart rate reserve (% HRR),
meaning the difference between your resting heart rate and maximum heart rate (HRR
= HRmax - HRrest).
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.
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).
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).
zone – bpm / % / % HRR:
This feature enables you to manually enter the target zone that 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%).
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
– calorie expenditure with altitude adjustment: Polar OwnCal calculates the number of calories burned during
training. This feature allows you to track the calories burned during one
training session and cumulative calories burned during several training
sessions. The effect of the ambient air pressure is taken into account in the
calorie expenditure calculations: in moderate and high altitude there is less
oxygen in the air so you can do less work and expend fewer calories at the same
(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.
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 under train or over train in the long run.
Based on the test, you are provided with a scale and description of your
personal training status.
– 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.
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
/ 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.
– available via polarpersonaltrainer.com:
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 under training, and adjust training intensity and duration according to your
daily and weekly targets

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.
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.

Stride Sensor W.I.N.D. Features
Stride length is the average length of one step, that is, the distance between
your right and left foot contacting the ground. Runners adjust stride length to
gather speed: stride length increases as speed increases. Yet one of the most
common mistakes novice runners make is over-striding. The most efficient stride
length is the natural one – the one that feels most comfortable.
current, average and maximum:
Your cycling cadence stands for your pedaling rate in revolutions per minute
(rpm). Cadence is the central factor in improving cycling performance. A higher
cadence reduces the force needed for each pedal stroke, and thus improves
overall performance. Running cadence measures how many times you’re either right
or left foot hits the ground in one minute. Running cadence is measured as steps
per minute. With this feature you can sharpen your cadence and make your ground
contact time shorter. This will help you to find a balance between leg power and
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.
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
selection – settings for three shoes:
Shoe selection feature allows you to select shoes for a particular sensor in
your training computer and to follow your training distance for the particular
pair of shoes.
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
Speed/Pace-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

This feature points out graphically on the display the zone you are in during a
training session helping you to stay on the desired intensity zone.
trainer guided workouts – heart rate / pace / distance: Create interval guided workouts based on time, heart rate, speed/pace
or distance guidance with up to three linked timers or distances and up to three
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.
configurable displays – all 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 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.
ZonePointer is a visible and moving symbol on the training computer display
indicating whether you are inside the pre-set target zone. This feature helps
you to reach the desired intensity/pace/speed/cadence targets.
