dependent on its oxygen-uptake capacity. Aerobic
exercise should above all be pleasant. You should
perspire, but you should not get out of breath during the
workout. You must, for example, be able to speak and not
just pant while pedaling.
You should exercise at least three times a week, 30
minutes at a time, to reach a basic fi tness level.
Maintaining this level requires a few exercise sessions
each week. Once the basic condition has been reached,
it is easily improved simply by increasing the number of
exercise sessions. Exercise is always rewarding for weight
loss, because it is the only way of increasing the energy
spent by the body. This is why it is always worthwhile to
combine regular exercise with a healthy diet. A dieter
should exercise daily, at fi rst 30 minutes or less at a time,
gradually increasing the daily workout time to one
hour.
You should start slowly at a low pedaling speed and low
resistance, because for an overweight person strenuous
exercise may subject the heart and circulatory system
to excessive strain. As fi tness improves, resistance and
pedaling speed can be increased gradually. Exercise
effi ciency can be measured by monitoring the pulse. The
pulse meter helps you monitor your pulse easily during
exercise, and thus to ensure that the exercise is suffi ciently
effective but not over-strenuous. Start your workout with
slow tempo and low resistance. Gradually increase tempo
and resistance according to your own condition. Keep
your head up and neck long in order to avoid stress on
your neck, shoulders and back. Keep also your back
straight. Make sure that your feet are centered on the
foot pedals and that your hips, knees, ankles and toes are
facing forward. Keep your body weight centered over
your lower body regardless of whether you lean forward
or stand upright. Stop your workout by gradually
decreasing tempo and resistance.
Don't forget to stretch afterwards. To strengthen
cardiovascular system, maintain low resistance but high
tempo. Exercising with higher resistance and slow tempo
strengthens correspondingly your back and hips.
HEART RATE
No matter what your goal, you'll get the best results by
training at the right level of effort, and the best measure is
your own heart rate.
The C20 meter has a heart rate receiver compatible with
Polar equipment, so you can also use Polar uncoded
heart rate transmitter belts for heart rate measurement.
NOTE! If you are fi tted with a pacemaker, please consult a
physician before using a heart rate transmitter belt.
The most reliable heart rate measurement is achieved
with a telemetric device, in which the electrodes of the
transmitter fastened to the chest transmit the pulses from
the heart to the console by means of an electromagnetic
fi eld. If you want to measure your heart rate this way
during your workout, moisten the grooved electrodes
on the transmitter belt with saliva or water. Fasten the
transmitter just below the chest with the elastic belt, fi rmly
enough so that the electrodes remain in contact with the
skin while exercising, but not so tight that normal breathing
is prevented. If you wear the transmitter and belt over a
light shirt, moisten the shirt slightly at the points where the
electrodes touch the shirt. The transmitter automatically
transmits the heart rate reading to the console up to a
distance of about 1 m.
If the electrode surfaces are not moist, the heart rate
reading will not appear on the display. If the electrodes
are dry, they must be moistened again. Allow the
electrodes warm up properly to ensure accurate heart
rate measurement. If there are several telemetric heart
rate measurement devices next to each other, the
distance between them should be at least 1.5 m. Similarly,
if there is only one receiver and several transmitters in
use, only one person with a transmitter should be within
transmission range. the transmitter is switched to an active
state only when it is being used for measurement. sweat
and other moisture can, however, keep the transmitter in
an active state and waste battery energy. therefore it is
important to dry the electrodes carefully after use.
When selecting training attire, please note that some
fi bers used in clothes (e.g. polyester, polyamide) create
static electricity, which may prevent reliable heart rate
measurement. Please note that a mobile phone, television
and other electrical appliances form an electromagnetic
fi eld around them, which will cause problems in heart
rate measurement.
HAND GRIP PULSE MEASUREMENT
(HGP-VERSION)
Pulse is measured by sensors in the handlebars. Pulse is
measured when the user of C20 is touching both sensors
simultaneously. Reliable pulse measurement requires that
the skin is constantly touching the sensors and that the
skin is slightly moist. Too dry or too moist skin weakens the
reliability of hand pulse measurement.
HEART RATE IN TRAINING
First fi nd your maximum heart rate i.e. where the rate
doesn't increase with added effort. If you don't know your
maximum heart rate, please use the following formula as
a guide:
220 - AGE
The formula gives an average value; the maximum varies
from person to person. The maximum heart-rate diminishes
on average by one point per year. If you belong to a risk
group, ask a doctor to measure your maximum heart rate
for you.
We have defi ned three different heart-rate zones to help
you with targeted training.
BEGINNER: 50-60 % of maximum heart-rate
Also suitable for weight-watchers, convalescents
and those who haven't exercised for a long time.
Three sessions a week of at least a half-hour each is
recommended. Regular exercise considerably improves
beginners' respiratory and circulatory performance and
you will quickly feel your improvement.
TRAINER: 60-70 % of maximum heart-rate
Perfect for improving and maintaining fi tness. Even
reasonable effort develops the heart and lungs effectively,
training for a minimum of 30 minutes at least three times a
week. To improve your condition still further, increase either
frequency or effort, but not both at the same time!
