Training modes mean the different ways a
training equipment can be set to control and maintain the training intensity.
Using the different modes will make the training more versatile, motivating, and
even more effective. Usually, the same modes can be used either in manual
training in which you select the mode and then adjust the intensity manually
during training, or in pre-set profiles in which the training equipment will
control the changes of intensity partially or totally automatically.
1. Constant Watt in which you set the training intensity in watts (W). In
this mode, the wattage is independent of the pedaling speed (rpm).
2. Constant Resistance in which you set the training intensity in Newton meters
(Nm), i.e. you set the torque, i.e. the power needed to turn the cranks. The
pedaling effect is the same as with a single-speed bicycle – the faster you
pedal, the higher the output power (= intensity / watts). In these profiles the
wattage is dependent of the pedaling speed (rpm). The popular name for this mode
is manual mode. The name is derived from the fact that especially in earlier
fitness equipment, the resistance was set manually. Fitness cycles use only this
3. Constant Heart Rate in which you set the desired heart rate level for the
In all these constant modes you set the desired intensity level prior to the
start of the training, and the training equipment automatically controls the
brake so that the set intensity level remains. Obviously, you can change the
intensity level in all these modes during training.
The basic idea of profile scaling is to ensure that you can always use
the pre-set profiles to maximum effect. Everyone knows that the required
training intensity varies – sometimes you want to exercise hard, sometimes an
easy and short exercise is just right. In order to take the exerciser’s current
training capacity into account, the exerciser must have the possibility to
adjust, i.e. to scale the intensity and duration of the pre-set profiles.
The scaling of intensity (speed, elevation, watt, Nm, HR) can take place
either before or during training: if you notice that the profile is too low for
you, you can scale it upward simply by pressing one key until the desired level
is reached. Similarily, scaling the profiles down is possible. In scaling, the
pre-set profile form will remain, but the profile intensity level will go up or
down. Prior to the start of the exercise, you can set the desired duration
(time, in some cases distance) of the profile.
In brief, scaling is the ultimate application for personalized, effective
Permanent Magnet Brake
In the permanent magnet system there is a magnet caliper or fork, i.e. a moving
element to which pieces of magnet are attached. The resistance is generated by
adjusting the distance of the magnets to the flywheel: the closer to the
flywheel the magnets are, the greater the resistance to the flywheel and cranks.
The features of this system are:
1. no wearing parts, maintenance free, very low probability of any
2. practically no need for re-calibration: the products are calibrated in the
production, and basicly only product abuse can alter the calibration. The
re-calibration is possible with a dynamometer
3. quiet in use as there are no wearing parts
4. the permanent magnet brake can be adjusted either electronically with the
assistance of a servomotor from the console or manually with an adjustment knob
5. the magnets Tunturi uses have an effect radius of about 10 cm, and they do
not cause radiation or electronic disturbances to their environment
6. very smooth resistance feeling, impact-free
The heart rate measurement is based on electrical impulses registered
from the heart, whereas pulse meters measure peripheral circulation e.g. via an
ear clip or a handgrip to calculate the pulse rate. If you use a heart rate
controlled exercise program or if the heart rate value is of importance to you,
Tunturi recommends using a transmitter belt for continuous heart rate
measurement. Pulse measurement is in principle equally accurate, but
functionally more limited and for some users unreliable way of measurement.
Wireless (Telemetric) Heart Rate Measurement
Tunturi recommends using the heart rate belt due to its superior reliability
and accuracy. Most Tunturi fitness equipment have an inbuilt heart rate receiver
for measuring heart rate wirelessly, i.e. telemetrically. When using telemetric
measurement, moisten the electrodes carefully and attach the belt so that the
electrodes are tightly against the skin. The belt transmits the heart rate
signal to appr. 1 meter distance.
When selecting training attire, please note that some fibers 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 field around them, which may
cause problems in heart rate measurement. If you suspect this, move your
equipment to another place and check the function of heart rate measurement.
Tunturi delivers only uncoded Polar transmitters with selected equipment. Notice
that uncoded transmitters disturb one another if they are used close (less than
1.5 m) to each other.
How the heart rate is measured?
As the heart rate level changes constantly, the displayed value is always an
average from a certain time period. Manufacturers use different algorithms, i.e.
mathematical formulas, to calculate the average heart rate value. For this
reason, the heart rate values shown in heart rate receiving watches and in
Tunturi meter consoles may differ slightly. The faster the change in the heart
rate level, the greater the variation in different receivers. Note, too, that
Tunturi does not recommend using two receivers in training simultaneously: in
some cases a watch receiver may cause interference to the meter console heart
Handgrip Pulse Measurement
Handgrip pulse is also an easy method for measuring the pulse. It does not
require any additional devices, the measuring sensors are an integral part of
the product. The pulse measurement is effected by touching the two sensors in
the handlebar simultaneously. Handgrip measurement requires that the skin is
constantly touching the sensors and that the skin is slightly moist.
