    A description has been made of a physical training device for use by cross-country skiers and other athletes comprising two first endless conveyor belts 2. The belts are connected to one or more flywheels 6. The flywheels provide an inertia similar to the conditions of a skier sliding forward. The bands 2 are placed approximately parallel. Between the straps 2 a platform 5 is placed in such a way that one can also stand on the platform between the straps 2 and stake with a ski pole on each strap 2. The platform can comprise one or two laterally adjustable other endless roller straps 7 which the practitioner can kick off at the same time as the rod is taken. The rolling resistance of the belts can be regulated with a magnetic or other type of adjustable resistance and is controlled to simulate different travel profiles. Furthermore, adjustable raising devices 4 can be mounted on the front of the endless conveyor belts 2, 7 in order to achieve the effect of an uphill slope. 1

    "Vasa trainer" (wwwyasatrainencom) is a similar device, but in this case the practitioner sits or lies on a cart pulled up with his arms. Incidentally, it is very similar to the well-known Norwegian "bråsterk".
    With Nordic track ski exercise machine (www.nordictrack.com) both arm and leg training is available. You pull on a strap with your arms and move your legs back and forth.
    There are also a number of other similar so-called "ski exercise machines" where you move your arms and legs back and forth.
    A treadmill for roller skis is a device with a high degree of imitation, but is hardly relevant as a device for training at home or in the gym because they have a typical size of 3 x 3 m and a weight of 250 kg.
    There are also large treadmills for skis where the user stands on a treadmill and has two side belts for the poles. In addition, the friction of the side belts can be adjusted to get a suitable load for the user. When skiing, the practitioner has an accelerating momentum in most of the skiing. The practitioner slides further at a decreasing speed before a new pole vault is taken. Conveyor belts with rollers at each end give very little torque in the belt when the practitioner stakes and in addition the friction is added to the belt.
    In other words, the belt rolls very little or nothing when the rod is made. When the belt swings between each rod pull, it gives a feeling and movement that does not mimic stacking with propulsion very much.
    The Norwegian Xcpro system has motorized belts where the speed is computer-controlled.
    The rolling resistance in this system is constant. There is no acceleration under the pole vault and you also do not achieve a realistic experience of sliding forward on skis.
    SUMMARY OF THE INVENTION The object of the invention is to construct a device for physical training which better mimics stacking on skis than previously known devices.
    This is achieved with a device as defined in the appended claims. More particularly, the invention comprises a device for physical training for cross-country skiers and other athletes with two first endless treadmills. The bands are placed roughly parallel. Between the straps, a platform is placed in such a way that you can also stand on the platform between the straps and stake with a ski pole in each strap. The straps are connected to one or more flywheels. Brief Description of the Drawings The invention will now be described in detail with reference to the accompanying figures, in which Fig. 1 shows the embodiment of the invention seen from above, Fig. 2 shows an alternative embodiment of a component of the invention, Fig. 3 illustrates a detail in the embodiment shown in Fig. 1.
    Detailed description The device according to the invention is shown in the drawings where figure 1 shows the device seen from above and 3gur 3 from the front side. The invention consists of two first conveyor belts 2 which are mounted at a certain distance and substantially parallel to each other.
    The practitioner stands between the bands and stakes with the poles on the bands. The first conveyor belts 2 which the practitioner stakes with a rod on each belt can be free-standing so that the base forms a platform, but they can also advantageously be mounted to a raised platform 5 which can be adjusted laterally and which the practitioner stands on to stabilize the straps and to stand at the same height and angle in relation to the ground as the straps 2. The first straps 2 are fastened with laterally adjustable devices 3 on the platform. Alternatively, the platform may comprise one or two other conveyor belts 7, according to the illustration in Fig. 2, used for kick-off.
    Each of the first conveyor belts runs between two rollers or rollers located at each end of the belt. At least one of the rollers is equipped with at least one flywheel. The flywheel greatly contributes to giving the user a realistic feeling of skiing, as it gives an inertia in the belt so that the speed does not decrease too much between each pole pull and the user feels that the system gives way in a familiar way when it increases the force in the "kick-off" to increase speed. In terms of dimensions, it can be an advantage to use two smaller flywheels 6 on each side of the roller instead of a larger flywheel. For the same reason, flywheels can also be used on both rollers, i.e. at each end of the band.
    The rolling resistance of the belts 2, 7 can be regulated by means of e.g. steel wheels with adjustable magnetic resistance. The steel wheels can be built into the Flywheel or the flywheels 6.
    The magnetic system can be connected to a computer 8 which controls the rolling resistance. You can thus program the rolling resistance, or in other words the riding profile, for a certain ride. Large resistance on the uphill slope and small resistance on the downhill slope. 20 25 30 At the front of the straps and the platform the user is standing on, an adjustable raising device 4 can be attached, see fig. 3, so that you get an effect similar to an uphill slope.
    It also provides a certain increase in rolling resistance (up to 6% according to the manufacturer).
    The device according to the invention may also comprise a contact sensor. A system that shows where the pole vault begins, where it ends and the number of cm the pole is in contact with the ground per pole pole in relation to how the practitioner stands. This is very interesting for the user's technology development and can be solved with a magnetic strip (receiver) along or under the band and a magnet at the end of the rod. Ev. fl your receivers can be used along the belt and a magnet at the end of the rod. The same principle is used for bicycle computers, where a receiver is attached to the front fork and a magnet is attached to a spoke. Other types of sensors, which are not magnetic, can also be used, e.g. electromagnetic or capacitive systems, or pure pressure sensors.
    The contact sensor mentioned above can also be used as a frequency meter. The magnet attached to the end of the rod comes close at each rod pull close enough to a receiver attached to the belt and which sends an impulse to a connected computer which shows the number of rod pulls per unit time. The information is interesting when it comes to the user's technology development, e.g. which frequency and length of rod rods gives the best propulsion within a certain period of time.
    In some cases, it may be beneficial to use a seat belt attached to the back of the hip belt. For new staking technology, it is important to bring the hip up and forward correctly before taking the pole bar itself. The strap prevents the practitioner from getting too far forward or simply falling. For very skilled users, this may not be necessary, but for users who are learning the technology, this is very helpful, as technology improvement is an important reason why treadmills are used.
    The device according to the invention gives a very high imitation when it comes to stacking on skis because ordinary ski poles are used. You stack on relatively soft endless conveyor belts which thus do not give the same unwanted load on the back, shoulders and arms that hard shocks with rods on asphalt can give. When the practitioner shoots with a pole on each belt, the belts get an increase in speed in the same way as skis get on snow when the practitioner stakes on snow. The resistance in the conveyor belts is adjustable and the device is thus very suitable for both heavy strength training, interval training with high intensity and for light, calm pole pulls. Simulation of an uphill slope can be done with a lifting device at the front. The straps can advantageously be connected to a platform to stand on so that the practitioner stands at the same height as and has the same angle as the straps. You can also connect additional bands between the first two used for kick-offs. In this way, you can perform both double stakes with or without kick and diagonal stakes. Both the platform and the straps for kicking can be adjusted laterally on the straps for stacking so that the distance between them becomes correct in relation to the practitioner's anatomy. The device is very mobile and light and it can be used practically anywhere all year round. It is very suitable for observation and various analyzes, pre-adjustment of the practitioner's technique. One can e.g. film from different angles and both the practitioner himself and the trainer can watch while the training is in progress.
    This is achieved with the invention in that the device consists of two endless conveyor belts with the length 7/8 to 4/3 of the practitioner's length, depending on the rod length and technique.
    The straps used for pole pulls can be of different materials so that rods with spikes for snow or asphalt, or different types of friction spikes can be used. The straps used for kicking have a design and a choice of material of such a type that the necessary friction between the straps and ordinary jogging shoes is achieved.
