Description

Technical Field

[0001] The invention relates to a training device having a measuring system for detecting a motor performance produced by a trainee and a control system with an input channel for detecting a burden value and an output channel for predetermining the motor performance to be produced, wherein the control system is configured for executing a method comprising the following steps:

[0002] a) predetermine the initial burden value,

[0003] b) detecting the resulting exercise performance value when the initial load value is reached,

[0004] c) forwarding the resulting value of the athletic performance via said input channel,

[0005] d) calculating the sport performance to be produced for the training load value depending on the body load perception scale, and outputting it through the output channel. Background Art

[0006] In training units on training equipment for rehabilitation purposes, it is important to ensure that the trainee's training intensity is correct in order to prevent injuries, but still achieve a reasonable training effect. In the medical field, the correct training intensity can be determined with the help of a body load perception scale, in particular a linearized body load perception scale, such as the Borg-Skala. The Borg scale is used to determine the burden of a person based on his subjective sense of effort. Here, the burden level of the Borg scale depends primarily on the person's heart rate. In order to measure the heart rate, external sensors such as heart rate monitors have been used so far, which record the heart rate of the trainee during the entire training period and output it visually in most cases, which makes the overall assembly more complicated. It is also problematic that commercially available low-cost heart rate monitors are not approved for use as medical instruments due to cost, and therefore using them for medical purposes is problematic and creates a liability risk. Summary of the invention

[0007] The object of the invention is therefore to create a possibility to control the load on the trainee even without external sensors.

[0008] This object is achieved by a training device having the features of claim 1. Advantageous embodiments of the invention with expedient developments are specified in the dependent claims.

[0009] The training device according to the invention is particularly unique in that it has a measuring system for detecting the motor performance produced by the trainee and a control system with an input channel for detecting the burden value and an output channel for predetermining the motor performance to be produced. In addition, the control system is intended to implement a method comprising the following steps:

[0010] a) predetermine the initial burden value,

[0011] b) detecting the resulting exercise performance value when the initial load value is reached,

[0012] c) forwarding the resulting value of the athletic performance via said input channel,

[0013] d) calculating the sport performance to be produced for the training load value depending on the body load perception scale, and outputting it through the output channel.

[0014] This results in the following advantage: the training workload value can be detected more quickly and simply by using the knowledge provided by a scale, in particular provided by a Borg scale, i.e., a Borg CR 10 scale and / or a Borg CR 20 scale, compared to detection using an external sensor (e.g. a heart rate monitor).

[0015] That is, the control system only needs to be calibrated once at the beginning by associating the detected exercise performance with an initial stress value, so that the control system can subsequently be used in a targeted manner to query the desired exercise performance and the heart rate associated therewith.

[0016] The training device can also, in step e), predetermine a time-dependent motion performance characteristic curve for the training burden value through the control system. In addition, there is an output unit, which is used to send the deviation of the actual value of the training burden value from the motion performance characteristic curve from the rated value as a signal. That is, the entire training unit can be operated without external sensors, and the person to be trained is prompted by the output unit that the training must be adapted to achieve the rated value. In one embodiment, the output unit is formed as a display screen; the display screen makes it easier for the trainee to understand and accept the instructions given by the training device. In another embodiment, the output unit itself can give an acoustic signal. The two embodiments mentioned above can be combined.

[0017] In order to achieve the desired training effect, the control system is designed to change the speed and / or resistance in order to adapt the sports performance from the sports performance characteristic curve. In another embodiment, the training device can be associated with a measurement system, which is used to control the physical burden of the trainee when the initial burden value is reached. The measurement system can be designed to detect heartbeat and / or oxygen consumption and to ensure that the Borg scale is used as a redundant control means, so that it does not need to monitor the entire training but only warns before reaching the limit value.

[0018] Without departing from the framework of the present invention, the features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the figures and / or shown separately in the figures can be used not only in the respectively given combination, but also in other combinations or alone. Therefore, embodiments not explicitly shown or explained in the figures can also be regarded as being included and disclosed by the present invention, but emerge from the described embodiments and can be produced by individual feature combinations. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Further advantages, features and details of the invention are apparent from the claims, from the following description of preferred embodiments and with the aid of the drawings. The drawings show:

[0020] Figure 1 showing a perspective view of a training device,

[0021] Figure 2 shows the individual perceived effort according to the Borg CR10 scale for individuals with different motor performance abilities, and

[0022] Figure 3 A graphical representation showing a motion performance profile as a function of time. DETAILED DESCRIPTION

[0023] Figure 1 A training device 1 is shown in the form of a dynamometer, which is suitable for training the arms and thighs and has a pivot unit 3 with a forced coupling to change the limb to be trained, but wherein the training device can also be formed in the form of a treadmill, stepper, or rowing machine, not shown in the drawings.

[0024] The training device 1 is associated with a measuring system for detecting a motor performance produced by a trainee and a control system with an input channel for detecting a burden value and an output channel for predetermining a motor performance to be produced, wherein the control system is configured for executing a method comprising the following steps:

[0025] a) predetermine the initial burden value,

[0026] b) detecting the resulting exercise performance value when the initial load value is reached,

[0027] c) forwarding the resulting value of the athletic performance via said input channel,

[0028] d) calculating the sport performance to be produced for the training burden value depending on the personal burden perception scale and outputting it through the output channel.

[0029] The physical load scale may be given by a Borg scale, in particular a Borg CR 10 scale and / or a Borg CR 20 scale.

[0030] Here, the Borg scale is a scientifically well-studied scale for determining a person's burden based on subjective feelings of effort ( Figure 2 ), where the current linearized Borg CR 10 scale is according to the following diagram:

[0031] 0 = No effort at all

[0032] 0.5 = Very, very slight (almost imperceptible)

[0033] 1 = Very mild

[0034] 2 = Mild

[0035] 3 = Medium 4

[0037] 5 = Severe 6

[0039] 7 = Very severe 8 9

[0042] 10 = Extremely severe (close to the maximum)

[0043] The Borg scale forms a linear relationship between perceived effort, heart rate, and individual workload. Figure 3 In the table below, the individual perceived effort is shown for individuals with different motor performance abilities. Here, the values ​​0 to 2 of the Borg scale correspond to rest, the interval 2 to 3 to a light load, the interval 3 to 5 to a medium load, the interval 5 to 7 to a heavy load, and the interval 7 to 10 to a maximum load. In the table below, another numerical scale is given based on the oldest historical scale (i.e. the Borg CR 20 scale), which, like other effort scales, can be converted into the current Borg scale.

[0044] Borg Scale Value pulse The state of perceived exertion 6 60 Effortless 7 70 Very slight 8 80 9 90 Very slight 10 100 11 110 slight 12 120 13 130 Slightly serious 14 140 15 150 serious 16 160 17 170 Very severe 18 180 19 190 Extremely severe 20 200 Most laborious

[0045] In the table, the linear relationship between the values ​​of the Borg scale and the heart rate can be found again. The effort perception is specified in the right column, so that here the corresponding values ​​in the Borg scale can also be deduced based on the subjective effort perception.

[0046] exist Figure 3 An exemplary time-dependent motor performance characteristic curve is shown in FIG. 4 , which is predetermined by the control system in step e). Figure 3 The image shown in exemplarily represents the rated value of the training burden value of the training unit at each time point. In order to send the deviation between the actual value of the training burden value and the rated value as a signal, an output unit is provided. This output unit is formed as a display screen 2 in the present invention. In other embodiments, in order to send a signal, an acoustic signal and / or a vibration signal is also provided supplementarily when appropriate.

[0047] The control system of the training device 1 is designed to change the speed and / or resistance in order to adapt the sports performance from the sports performance characteristic curve. In addition, the training device 1 has a measuring system for controlling the physical load of the trainee when an initial load value is reached. The measuring system is designed to detect heart rate and / or oxygen consumption.
