User settings
Most Tunturi equipment feature user settings, with which the equipment can be made more
personalized, i.e. you can make settings according to which the console or the equipment
works. The more advanced Tunturi equipment feature a user register, which allows saving
your personal information in the meter console.
Depending on the model, you can e.g. set the user gender, weight, age, measurement units,
audio signals, etc. In some models, the total training time and distance per user can also
be found in the User Register. The console will use the user information to calculate the
energy consumption with greater accuracy, and usually the console programs are constructed
so that self-made profiles are saved under the selected user. Back to top
Flywheel weight
The heavier the flywheel, the better, right? Well, no. The idea of heavy flywheel
superiority dates back to the early years of fitness equipment business. Back then, the
training motion was made smooth by having a large diameter and heavy flywheel as a
counterweight to the training movements. Such a flywheel, however, made the products
clumsy looking, heavy and difficult to move.
In the recent years, the heavy flywheels are increasingly being replaced by lighter and
smaller wheels, but at the same time the transmission ratio is made considerably higher. A
lighter flywheel produces just the same pedal smoothness, if only the transmission ratio
is set correctly. Then the flywheel will spin at a very high speed and produce such
inertia (power of continuous movement) that the faster moving, lighter mass equals a
slower moving, heavier mass. Consequently, we can build more attractive design products,
which are also lighter and easier to transport. Back to top
Training modes
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.
In cycles, Tunturi uses three training modes:
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). Fitness cycles use only this mode.
3. Constant Heart Rate in which you set the desired heart rate level for the exercise.
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. Back to top
Pre-set training profiles
In the pre-set training profiles, the
changes of training intensity will take place automatically - this makes training
interesting and motivating. Furthermore, Tunturi have carefully designed the pre-set
training profiles for various exercise targets, and they give maximum effect towards the
desired exercise target. In brief, the greatest benefit of the pre-set profiles is that
they make effective training very easy.
In cycles, Tunturi uses another three profile modes:
1. Watt (or power) profiles in which the training intensity is pre-set in watts (W); in
display, the higher the profile,
the higher the intensity in watts. In these profiles the wattage is
independent of the pedaling speed (rpm).
2. Resistance profiles in which the training intensity is pre-set in Newton meters (Nm).
In these profiles the torque,
i.e. the power needed to turn the cranks is pre-set. Again, the higher
the displayed profile, the higher the
intensity. However, the pedaling effect is the same as with a
single-speed bicycle – the faster you pedal, the
higher the output power (= intensity / watts). In other words, in these
profiles the wattage is dependent of the
pedaling speed (rpm).
3. Heart rate controlled profiles in which the profile shows the run of heart rate during
the exercise. Back to top
Heart rate measurement
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 rate
measurement.
Ear Sensor and Handgrip Pulse Measurement
Ear sensor is an easy way of measuring pulse. When measuring pulse with an ear sensor,
make sure the sensor plug is correctly connected to the meter. Attach the ear sensor to
the ear lobe and attach the sensor wire for example to the collar with the clip; this
prevents the sensor from moving during exercise.
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.
Avoid problems when using the pulse measurement:
1. At high heart rate frequencies blood circulates so evenly in the capillaries that the
sensors can not distinguish
separate pulses. This phenomenon appears usually at around 150 beats
per minute, and it is indicated by
strongly alternating pulse values or by pulse value disappearing from
the display.
2. With the ear sensor, the exerciser may move so that the sensor surfaces do not stay
firmly against the ear
lobe. Notice that the Tunturi ear sensor design enables measuring pulse
on the inside surface of the ear.
Furthermore, depending on the anatomy and circulation of the ear lobe,
some people may not get a reliable
pulse reading with the ear sensor.
3. With the ear sensor, strong light sources close to the user may disturb the infrared
sensor light. Notice that the
Tunturi ear sensor design enables measuring pulse on the inside surface
of the ear.
If measuring from the ear lobe, you can rub it to improve the circulation or try pulse
measurement from the tip of a finger. Unlike with the heart rate belt, the accuracy of
pulse measurement may vary considerably from person to person. Back to top
Brake Systems
Electromagnetic Brake
The electro-magnetic brake is the latest brake system introduced to the fitness equipment.
The basic system is simple: the exerciser controls the current fed to the electromagnet
from the console; the more current is fed to the electromagnet, the greater the resistance
to the flywheel and cranks.
The features of this system are:
1. No moving parts, no wearing parts, maintenance free, very low probability of any
malfunctions
2. Practically no need for re-calibration: the products are calibrated in the production,
and basically only product
abuse can alter the calibration. The re-calibration is possible with a
dynamometer
3. Very quiet in use as there are no moving or wearing parts
4. Extremely accurate, resistance setting in small intervals
5. Very smooth resistance feeling, impact-free
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 malfunctions
2. Practically no need for re-calibration: the products are calibrated in the production,
and basically 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
Air Resistance Brake
Air resistance brake is used above all in heavy-duty rowers. This brake construction
produces an authentic rowing feeling; resistance changes according to rowing speed.
Features of this system are:
1. No direct resistance adjustment: the stronger you pull, the higher the resistance. By
adjusting the flow of air to
the flywheel it is possible to control the basic resistance level
2. Generates some noise and an air wave
3. Very smooth, continuous and impact-free rowing
Belt Brake
Belt brake is based on a belt around the outer rim of the flywheel. By adjusting the
tightness of the belt, the resistance is increased or reduced. The belt is a wearing part.
Hydraulic Piston
Hydraulic pistons are basically the same as shock absorbers in cars. The pistons are
filled with liquid lubricant, and the resistance level can be adjusted with the adjustment
ring on top of the piston. Demanding use may cause the piston surface to heat up
noticeably. The pistons are wearing parts. Back to top
Profile Scaling
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. Similarly, 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 training. Back to top
Product Standards
TEST REQUIREMENTS
The planning and manufacturing of fitness equipment includes numerous tests to ensure that
they will not cause a risk to the exerciser or disturbances to the environment. Every
Tunturi fitness equipment model is thoroughly tested prior to the commercial launch. The
following standards apply to the Tunturi fitness equipment:
Product Safety Requirements
EN 957-1+A1: general fitness equipment safety requirements and test methods
EN 957-5: safety requirements of pedal crank training equipment
EN 957-6: safety requirements of treadmills
EN 957-7: safety requirements of rowing machines
EN 957-8: safety requirements of stair climbers and steppers
EN 957-9: safety requirements of crosstrainers
EN 60355-1: general safety requirements on household and similar electrical appliances
The EN standards are pan-European and they define the general and product group
specific requirements according to which the mechanical components, structures and
functions can be regarded as safe to user. The certificates on EN compliance are granted
to Tunturi fitness equipment by SGS and TÜV Product Safety GmbH. Both are international,
independent and highly respected in their trade.
Electrical Safety Requirements
The EMC-directive 89/336/EEC: directive on electromagnetic compatibility of electrical
appliances
The Low Voltage Directive 73/23/EEC: directive that ensures the electrical equipment
within certain voltage limits is safe for the user
UL 1647: Electrical safety requirements in the USA
CAN/CSA-C22.2: Electrical safety requirements in Canada
In fitness equipment, the electrical safety requirements ensure that the electric
components of the equipment will not cause safety risks to the exerciser. Furthermore,
they ensure that the equipment will not disturb the function of other electrical
appliances. Tunturi have certified various products also according to the North-American
requirements.
CE conformity marking
The CE conformity marking proves that the equipment meets the applicable product and
electrical safety requirements and is safe to use. All Tunturi equipment carry the CE
conformity marking.
DIN standards
DIN standards (Deutsche Industrienormen, German Industry Standards) were applied to
the Tunturi equipment prior to the introduction of the EN standards in 1996. Some Tunturi
products of older vintage carry the DIN certificate decal, granted by the German TÜV
Product Safety GmbH.
DIN 32932 A: Accuracy standard and general requirements for ergometer cycles
DIN 32932 B: General requirements for non-ergometer cycles with a freewheel
PRODUCT CLASSIFICATION
The product classification of fitness equipment is based on the EN 957-1 (general
fitness equipment safety requirements). The classification categorizes fitness equipment
into classes according to their specified operating environment and accuracy. For example,
the marking Class SA on the product means that the product is designed for professional /
commercial use and it conforms to the highest accuracy requirements.
Usage Classes
The usage classes applicable to the Tunturi equipment are S (= studio, i.e.
professional and / or commercial use) and H (= home). In the class S, the requirements to
the equipment are more demanding than in the class H. Therefore, a product with the S
usage classification can be used at home, but a product with the H usage classification
does not meet the requirements of the S class.
Accuracy Classes
The concept of accuracy classes has to do with the accuracy of the functions and
measurements of the equipment. There are three classes: A, B and C, of which A corresponds
to the highest requirements. Examples of the points of accuracy in fitness equipment are
measurement of training speed, effort and elevation of the running track. The accuracy
class division is based on the previous DIN-standards, and therefore the class A is
typically related to effort measurement and ergometers, the class B on the other hand to
products, which do not measure the training effort. Back to top
