It can be designed in various, known ways, for example as a friction braking device, as a magnetically acting braking device, as a generator for generating electrical energy or as a braking device acting against a fluid (e.g. a fan or elements rotating in a water vessel).

In this way, the result of their effort is made directly clear to the user, which has a motivating effect on the user. This creates an incentive to continue providing the training performance by allowing the user to intuitively determine what and how much they have achieved based on the movement caused by the actuator. This applies to an individual user, for whom the completed part of a predetermined training spectrum is clarified and made tangible in this way. This is particularly true for increasing comparability among multiple users, for example in a fitness studio, where the user with the highest training performance slowly moves ahead of the other users with lower training performance.

  • Figure 12 is a variant of Figure 7 shown. It differs from that in Figure 7 illustrated second embodiment in that a form-fitting track marking 100 'is provided. It has teeth on its top like a rack. The teeth are preferably rectangular in profile, so to create a surface that is easy to walk on, including in the area of the teeth.
  • the rollers 48, 48 'on the crossbars are not driven. Instead, the servo motor 94 of the actuator 9 acts on a serrated wheel 46. It has teeth on its outer circumference that are designed to complement the teeth of the track marking 100 '.
  • the serrated wheel 46 is mounted in the lower region of the frame 3 in such a way that its teeth on the outer circumference positively engage with the teeth of the track marking 100 '. In this way, a positive drive is formed, which causes a reliable and precise displacement of the frame 3 even in the event of contamination with liquids (sweat). This is particularly suitable for use in fitness studios or other sports performance centers where users achieve the highest level of physical performance.
  • Figure 13 Such use in fitness studios is in Figure 13 visualized with different views.
  • Figure 13a shows several bicycle ergometers 1, 1 'according to the invention, which are set up next to each other in a fitness studio with their floor track markings 100 parallel to one another. At the start they stand next to each other and during training they are moved by the actuator 9 depending on the training performance of the respective user.
  • the relative positioning is also shown here. If two users are competing for a position (e.g. the leadership position), thanks to the amplifier module 82 it can be highlighted to make it clear which user is currently in the lead, even if the lead is only a few centimeters. In this way, the competition for places can be clearly experienced, even if the simulated competition route is shortened from 10 or 100 km to a typically 5 to 15 m short movement along the ground track marking 100.
  • the invention also makes use of this: that the loss of position of a user relative to another user may then also result in a reversal of the actuator 9, ie the user falling behind in the position sequence then moves not only relative to the others, but also absolutely backwards.
  • FIG 13c an example of aligning the bicycle ergometers 1, 1' on the ground track markings 100 is shown. This is particularly important if several bicycle ergometers 1, 1' are to be operated next to each other in order to ensure parallel operation and avoid collisions with the neighboring device.
  • the tracking module expediently works together with an alignment module, which displays deviations recognized by the tracking device 97 on the display device 24 in order to support rapid and correct alignment.
