Description

Strength training device and method for specifying a resistance profile

The invention relates to a strength training device having at least one resistance element for applying training forces to at least one manipulator and to a method for specifying a resistance profile for performing an exercise on a strength training device having at least one resistance element.

Various types of weight-training devices are known, including power stations, individual devices and cable or cable devices. In power stations, several different manipulators are connected by rope or chain drives with a weight stick, so that it can be raised to perform various exercise against resistance, for example, when a proposed leg muscle exercise, arm muscle exercise or back muscle exercise is performed. Single devices are mainly installed in gyms and are usually used to perform a specific exercise movement, which conventionally also raises a weight stick to perform the exercise. These devices usually have only one or two symmetrical manipulators, which are connected to the same weight stick. When Seilzuggeräten a withdrawal of one or two symmetrical manipulators, which are each attached to one end of a rope, provided, which in turn is conventionally connected to a weight stick. The pulling out of the manipulator on the rope can be done in different directions, so that no specific exercise movement is given, but different exercises are possible. In all these devices, a certain force curve or torque curve is normally predefined via kinematics, for example via ropes guided on eccentric disks, so that the force to be overcome at different points of the training movement can be different. Depending on this predetermined curve, the weight to be raised during the exercise may be determined prior to the exercise to ensure appropriate exercise resistance.

In recent years, strength training devices have been increasingly offered in which the training resistance is applied by a suitably controlled electric machine instead of by a weight. The endeavor of manufacturers of weight training devices was usually to emulate the training behavior of such electromechanical strength training devices as well as purely mechanical strength training devices as well as possible. In the case of the electro-mechanical weight-training devices, too, a force curve is prescribed for an exercise to be performed which is intended to meet the physiological conditions of the exercise movement when it is carried out. An adaptation of the exercise performance is also generally here on a flat rate on the specification of a "weight value" (or similar) for the entire exercise performance. A personal adaptation, for example, to the preferences and / or needs of the trainee also takes place at most by means of an adaptation of the speed of the exercise or the number of repetitions to be performed.

An object of the invention is therefore to provide a strength training apparatus in which a resistance profile can be more flexibly and easily adapted to the preferences and / or needs of a user.

This object is achieved by a strength training device, which has at least one predetermined resistance profile for at least one exercise, in particular one, preferably exercise-specific, force or torque curve, a resistance display for displaying resistance profiles, a user input for entering at least one modified resistance value, in particular to each a value of a training parameter, a predetermined resistance profile and at least one resistance element for applying training forces on at least one manipulator of the strength training device. In this case, the force training device is set up to adapt the resistance element for performing the exercise to the changed resistance profile and to display the changed resistance profile at least substantially simultaneously with the input. An altered resistance profile can arise in particular by an input of at least one changed resistance value, preferably by a user.

According to the invention, a method for specifying a resistance profile for performing an exercise on a strength training device with at least one resistance element solves the problem, wherein such a method at least provides: displaying a predetermined resistance profile as a function of at least one training parameter, an input of an altered resistance value at least one value of the training parameter, adjusting the resistance element to the changed resistance profile, and displaying the changed resistance profile at least substantially simultaneously with the input.

For the purposes of the invention, a resistance profile is preferably understood to be a resistance curve (ie force curve or torque curve) that has a training parameter, such as a path or angle of rotation to be traveled during the training implementation, a time for practice execution, a speed and / or acceleration of the exercise execution , plotted or displayed. User input within the meaning of the invention is preferably set up to enable inputs by users such as a trainer or a trainer, in particular inputting of changed resistance values of a resistance profile.

An adaptation of the resistance element to the execution of the exercise on the changed resistance profile is preferably carried out before and / or during the execution of the exercise, d. H. before or during execution of the exercise movement.

The invention is based on the idea that in, in particular electromechanical, strength training devices in which a resistance element is preferably formed with an electric machine, an adaptation of the resistance to be overcome for exercise execution is also specifically for single or multiple waypoints along the exercise movement possible. Such a resistance adjustment, which is currently not made overall for the entire exercise execution, but as it were for individual path sections or waypoints, allows a variety of adaptation of the strength training device. Such an adaptation is on the one hand possible to individual specifications such as preferences or needs of the user such as imbalances, movement restrictions and / or relative contraindications, in each case for example in a rehabilitation situation (rehab). Furthermore, for example, in Seilzugkrafttrainingsgeräten, which allow a substantially free exercise performance, a specification of exercise-specific force curves possible, depending on the direction in which the cable is to be pulled out on the manipulator and / or which muscle group so that should be trained. This in turn allows, for example, a later adaptation to at the time of manufacture of the device unknown exercises.

According to one embodiment, the strength training device is arranged to display an altered resistance profile on the resistance display in response to a user entering an altered resistance value. In various developments of this embodiment, the display of the resistance profile can consist, for example, of a plurality of value pairs of a resistance value and the associated value of a selected and / or predetermined training parameter. Additionally or alternatively, the display may also have a graphical resistance profile in the sense of a force curve or a torque curve. These display options relate both to the display of a given resistance profile and to an altered resistance profile.

In a preferred development of this embodiment, the strength training device is set up for a real-time display of the changed resistance value. This gives the user of the device immediately after entering the changes an optical statement about what the now provided on the strength training device resistance profile looks, that is, which training resistance will be present in the different sections of the exercise movement. Preferably is under a real-time display (= display in real time) to be understood in the perception of the viewer at the same time as the input display.

In order to facilitate the display of resistance profiles and the entry of modified resistance values, according to one embodiment, the resistance display and the user input are formed together, in particular with a touch and / or gesture-sensitive screen, preferably with a capacitive touchscreen, optionally with motion detection. Preferably, a predetermined resistance profile and a resistance profile derived therefrom and derived by inputting at least one changed resistance value can be displayed on such a screen. For the purposes of the invention, it is possible, but not necessary, for a jointly formed resistance display and user input to be physically connected to the "training part" of the strength training device In this case, the data communication between the mobile phone or the tablet computer on the one hand, and the "on the one hand, and on the other hand, a tablet computer provided by the operator of the strength training device. Training part "of the power training device preferably by means of a wireless communication link such as Bluetooth or WLAN.

This embodiment is based on the idea of providing immediate feedback on input resistance values at the location of the input, preferably in real time. This can be achieved, for example, by displaying a force curve or a torque curve as a resistance profile on a touchscreen, and manipulating the same pointwise, area-wise or overall, for example according to a predetermined input function, by "dragging" with a finger at the display location of the curve. Such a "pull" then leads to a new course of the force or torque curve, which then represents a modified resistance profile.

For the purposes of the invention, various representations of the resistance profile are conceivable, for example in the form of a function graph or an interpolated graph, but also in the form of a point cloud or a bar graph, wherein the individual bars can then be lengthened or shortened for inputting a changed resistance value by means of a finger.

In order to allow easy access to predetermined and / or modified, stored resistance profiles, according to one embodiment, the strength training device has a memory unit for storing predetermined and / or modified resistance profiles. In order to enable a user-specific storage of predetermined and / or modified resistance profiles, the strength training device according to a further development has a user identification device. For such a user identification device are preferably in fitness studios common user cards for contact-bound and / or contactless identification in question, but also a scan of personality traits such as the iris of an eye, fingerprints or the like. Preferably, a user identified in this way is allocated a logical and / or physical memory part in the strength training device, in which his specific inputs of changed resistance values and / or changed resistance profiles can be stored as well as optionally a selection from a plurality of predetermined resistance profiles.

According to one embodiment, the force training device has a control unit which is set up to apply an input of a modified resistance value as a function of an input function to one or more adjacent values or all values of the training parameter.

According to one embodiment, the control unit is set up, the resistance element for

Exercise implementation to adapt to the changed resistance profile. This adaptation preferably takes place via an adjustment of the resistance applied to the manipulator as a function of the respective value of at least one training parameter taken into account.

In order to be able to specify a degree of fineness of the setting of the resistance profile, according to one embodiment, the control unit is set up to take into account a specification of an influencing interval in the input function. For the purposes of the invention, this may be understood to mean the distance between two adjacent values of a training parameter which can be changed in the sense of the invention as well as the size of a jointly influenceable set of values of a training parameter.

According to one embodiment, the strength training device has a control unit which is connected to the resistance display and with the user input for information exchange and is adapted to control a resistance value applied to the resistance element.

In order to give the user the most direct feedback possible for his input, the modified resistance profile is displayed according to an embodiment, in particular at least substantially simultaneously with the input.

For the simplest possible input, the changed resistance value is entered by means of a touch-sensitive and / or gesture-sensitive screen on which the display of the predetermined and / or the changed resistance profile takes place. In order to ensure problem-free (re) usability of resistance profiles, according to various embodiments one or more predetermined resistance profiles or a modified resistance profile are loaded from a memory unit of the strength training device onto the display and / or one or more modified resistance profiles are stored in the memory unit.

In order to ensure reusability of altered resistance profiles of different users, a user is identified, in particular modified by the user or a trainer, a resistance profile and / or a resistance value for that user and / or stored specifically for that user in the memory unit.

For applicability to strength training devices, which allow several different exercises (such as rope training devices), at least one own, variable resistance profile is given for different exercises.

According to one embodiment, for a given exercise at least two different resistance profiles are given, from which a user or a trainer can select and modify a preferred resistance profile, whereby a simpler entry of an altered resistance profile can take place.

In order to ensure a comprehensive adaptation of resistance profiles to different conditions, a time, a path, a rotation angle, a speed and / or an acceleration is considered and / or used according to an embodiment as a training parameter. As speeds or accelerations come rotatory and translational variables into consideration.

When a resistance profile with the exercise parameter "path" is used, this preferably means that the resistance profile represents at which point of an exercise movement which resistance value is applied to the resistance element of the weight training device.

When a resistance profile with the training parameter "rotation angle" is used, this preferably means that the resistance profile represents which resistance value is applied to the manipulator at a certain angle of the exercise movement, that is, by means of the resistance element.

A resistance profile with a speed as a training parameter can preferably be used to counteract a too high exercise speed, a higher resistance. enforce. The same applies to a training profile with acceleration as a training parameter.

If a resistance profile is used over time as a training parameter, it may thus be possible, in particular, to apply a, in particular successively increasing or decreasing, multiplication factor to the resistance values of another resistance profile with a longer exercise duration.

In order to enable a fine adjustment of a resistance profile also in several places, according to an embodiment, a changed resistance value can be entered at different, in particular identically spaced, values of a training parameter.

According to one embodiment, the resistance profile is displayed as a curve, and can be changed by touching a touch-sensitive screen and / or gestures in the detection area of a gesture-sensitive screen, each performed by a user or trainer, to at least one value of the training parameter.

The resistance profile can also be displayed as a bar graph or the like, in which case, for example, the length of the individual bars reflects the corresponding resistance value. Then the resistance profile can be changed by touching the display or appropriate gestures on / before the display of individual bars.

Other features, advantages and applications of the invention will become apparent from the following description taken in conjunction with the figures. It show, partly in a highly schematic representation

Torque profile of a strength training device of Figure 1;

FIG. 1 shows a strength training device 1 with a resistance element 2 embodied as an electric motor for applying training forces to a manipulator 4. The manipulator 4 has a lever 6 and a pad 8 and is designed so that it can carry out the only practicable with this training device 1 exercise (for example, a back extension) to a driven by the motor 2 shaft 10 within a certain angular range (rad ) can turn.

The training device 1 further comprises a body 12, in which in addition to the motor 2, a touch-sensitive screen (touch screen) 14 is arranged, which takes over the function of the resistance display 16 and the user input 18. 1 shows a predetermined resistance profile 20 designed as a torque profile for the exercise that can be carried out with the exercise device 1, wherein the resistance profile 20 has a function curve 22 with a highlighting of specific, manipulable resistance values 24. The function curve 22 is a representation of the values of a torque M provided along the angle range for the exercise, wherein a rotation angle α represents the training parameter taken into account.

In addition, the strength training device 1 has a control unit 26, which with the touch screen 14 as well as the resistance element 2 of a user identification device 28 for wireless identification of a user and with a memory unit 25 for storing resistance profiles via lines 30 for transmitting electrical energy and / or information connected is.

The manipulator 4 is movable by means of the resistance element 2 via a cable 32 from an angular position ao to an angular position ai. In this case, any intermediate angle values can be controlled, of which exemplary cf is shown in FIG.

In FIGS. 3 a and b, as in a strength training device 1 according to FIG. 1, a torque profile is shown as a resistance profile 20 for performing an exercise (as described in FIG. 1), in particular according to the personal preference of the exerciser with regard to the difficulty of the exercise at different angle values a, can be specified. 3a, the predetermined resistance profile 20 displayed on the touchscreen 16 before the start of the exercise but after an identification of the user by means of the user identification device 28 is shown for this exercise. The representation of the resistance profile 20 is effected by a mapping of a torque (M) angle position (rad) diagram 34, in which the torque curve 22 is drawn, which additionally has emphasizations of resistance values 24 with respect to the angular position α. In the area of this highlighting of the resistance display 16, the user can now, in particular by means of one or more fingers 36, change at least one resistance value 24 represented by the emphasis, that is to say enter an altered resistance value 24.

This process is illustrated schematically in FIG. 3b, which shows the touch screen 14 at a later point in time compared to the representation of FIG. 3a, in which the inputs of the changed resistance values 24 are already shown on the resistance display 16 '. For this purpose, the user with his finger 36 'first touches the resistance value 24.1 on the trained as a touch screen user input 18 and "pulls" the graphic emphasis representing the resistance value 24 so far down (indicated by the downward arrow) until the desired training moment, ie the desired resistance value 24.1 'for the assigned angle value α is reached, at which point the user removes his finger 36' from the touch screen, whereby the modified resistance value 24.1 'is entered Embodiment with a different or the same finger 36 ", because he wants to change another torque value 24.2 (in the example at the angular position cd).

In the control unit 26 of the strength training device 1, an input function is stored for these inputs, which has the consequence that the torque curve 22 'to be applied by means of the resistance element 2 is not adapted to the changed resistance values 24.1' and 24.2 'over the angle range a ₀ to CH but to achieve a steady torque curve, a new, adapted curve 22 'is interpolated.

FIG. 2 shows a strength training device 101, which differs from the single device shown in FIG. 1 mainly in that it is designed as a traction force training device, which in particular allows the execution of different exercises for different muscle groups with the same manipulator 104. The manipulator 104 is connected via a cable pull construction 132 to the resistance element 2 designed as an electric machine.

Unlike in the weight training device 1 according to FIG. 1, in the strength training device 101 according to FIG. 2, the exercise is not performed by a rotational movement, but by an at least substantially linear movement of the manipulator 101, that is to say by pulling the cable 133 of the cable 132 on Handle 108 trained manipulator 104 by the user. Since the extraction takes place at least substantially transversally in the various practicable exercises, a force curve 122 in which a training force F is plotted over the excerpt x of the manipulator 104 is shown in the resistance display 16 in contrast to the torque curve according to FIG ,

To perform exercises with the strength training device 101, the user removes the manipulator 104 from the position xo or x'o. Depending on the exercise to be performed, the cable 133 can be pulled out to a maximum point xi or χΊ, wherein the extension distances x and x 'should symbolize the possibility of performing various exercises on a cable traction training device 101.

The components of the strength training device 101, which correspond at least substantially to that of the strength training device 1 according to FIG. 1, are listed with the same reference numerals as there.

FIGS. 4a and 4b show, as in a strength training device 101 according to FIG. 2, a force profile as resistance profile 120 for carrying out various exercises "x" and "x", in particular according to the personal preferences with regard to the difficulty of the exercise at different extension values x or x ', can be specified.

4a, the force curve 122 predetermined for the exercise "x" is shown on the resistance display 16 formed as a touchscreen 14. Likewise, the force curve 122 'changed by the user's finger 36 is already shown.

The representation is made by an illustration of a force (F) path (x) diagram 134, in which the force curve 122 is plotted over the excursion path x, which has additional emphasis of certain resistance values (here force values) 124 in constant distances with respect to the extension position x , In the area of the highlighting 124 of the resistance display 16, the user has changed by means of his finger 36 three resistance values 124.1, 124.2 and 124.3 shown by highlighting, that is, in each case input a modified resistance value 124.1, 124.2 and 124.3.

In FIG. 4 a, the touch screen 14 is displayed at a time in which the inputs of the changed force values 124.1, 124.2 and 124.3 are already shown on the resistance display 16 in addition to and simultaneously with the predetermined force curve 122. This input takes place by means of a finger 36 in a manner analogous to the manner shown with respect to FIG. 3b. In the case shown, the user would like to start his exercise "x" at the stop xo with a much lower effort and achieve by his inputs that he is at the maximum Pulling point xi of the rope 133 must spend a slightly lower force F than would be the case after the predetermined force profile 122.

In the control unit 26 of the force training device 101, an input function is stored for these inputs, which has the consequence that the force curve 122 'to be applied by the resistance element 2 over the extension range xo to xi is not limited to the changed resistance values 124, 124.2 and 124.3. is adapted, but to achieve a steady force curve, a new, adapted curve 122 'is interpolated.

FIG. 4b shows how the force curve 222 of an exercise "x" is changed by the user at the force value 224 in a strength training device 101 according to FIG.

The change of the force value 224 takes place by means of the user's finger 36 analogously to the above descriptions to a higher force value 224 ', as indicated by the arrow in the illustration. In the exemplary embodiment illustrated in FIG. 4b, the user wishes to achieve that in the midfield of the movement between the stop x'o and the maximum excerpt χΊ a greater training resistance in the sense of a greater training force F is to be overcome.

An input function, which is stored in the control unit 26 of the strength training device 101 for these inputs with regard to the exercise "x" ', an influencing interval 240 is provided, within which the change in the force value 224 in the sense of interpolation of the course of the force curve 222' can influence this It is clear from the illustration that the force values at the boundary points of the possible movement of the exercise "x" ', namely x'o and χΊ, remain unchanged because they are outside of the influencing interval 240.

FIG. 5 shows a resistance profile 320 on a resistance display 316. Unlike in the exemplary embodiments illustrated so far, the resistance profile 320 has a force curve 322 which does not predetermine force values 324 as a function of a path x or an angle α, but rather as a function of an acceleration a. Here, the user can enter by means of his finger 36 for a certain acceleration value to be overcome resistance value 324 ', for example, to ensure that no hard stop occurs during the exercise, when the maximum pull-out xi or χΊ or the maximum angular deflection cii is reached. Typically, such a specification is made by a trainer accompanying the trainer who, for example, knows from the trainee's background that due to physical limitations he should not be exposed to such a hard attack. Not shown in the figures are resistance profiles in which resistance values can be changed as a function of a time or a speed. Velocity-based resistance curves can, for example, serve a similar purpose as described in FIG. A time-based resistance profile can serve to influence the training duration by successively reducing or increasing the training resistance.
