[0001] training device
[0002] DESCRIPTION:
[0003] The invention relates to training equipment with a measuring system for recording the performance provided by a trainee and with a control system with an input channel for recording a load value and with an output channel for specifying the performance to be provided, wherein the control system is set up to carry out a method comprising the steps of: a) specifying an initial load value, b) recording the value of the performance provided when the initial load value is reached, c) transferring the value of the performance provided via the input channel, d) calculating the performance to be provided for a training load value as a function of a scale for the physical strain perception and outputting it via the output channel.
[0004] During training sessions on training equipment used for rehabilitation purposes, it is important to ensure the correct training intensity for the trainee to prevent injury while still achieving an appropriate training effect. In the medical field, the correct training intensity can be determined using a scale for physical exertion perception, particularly a linearized scale for physical exertion perception, such as the Borg scale. The Borg scale is used to determine a person's exertion level based on their subjective perception of exertion. The exertion levels on the Borg scale are highly dependent on the person's heart rate.To measure heart rate, external sensors such as a heart rate monitor are currently used. These monitors record the exerciser's heart rate throughout the entire workout and, in most cases, display it visually, making the entire setup more complex. Another problem is that commercially available, inexpensive heart rate monitors are not approved as medical devices due to the complexity involved, making their use for medical purposes problematic and entailing liability risks.
[0005] It is therefore the object of the present invention to create the possibility of controlling the load of the trainee even without external sensors.
[0006] This object is achieved by a training device having the features of claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.
[0007] The training device according to the invention is characterized in particular by the fact that it comprises a measuring system for recording the performance achieved by a trainee and a control system with an input channel for recording a load value and with an output channel for specifying the performance to be achieved. Furthermore, the control system is designed to execute a method comprising the following steps: a) specifying an initial load value, b) recording the value of the performance achieved when the initial load value is reached, c) transferring the value of the performance achieved via the input channel, d) calculating the performance to be achieved for a training load value based on a scale for physical exertion perception and outputting it via the output channel.
[0008] This results in the advantage of a faster and easier recording of a training load value compared to the recording with external sensors, such as a heart rate monitor, by exploiting the information provided by the scale, which can in particular be provided by a Borg scale, namely the Borg CR 10 scale and / or the Borg CR 20 scale.
[0009] The control system therefore only needs to be calibrated once at the beginning by assigning the recorded power to the initial load value in order to subsequently use the control system specifically to demand the desired power with the associated heart rate.
[0010] The training device is also capable of specifying a time-dependent performance profile for the training load value via the control system in a step e). Furthermore, an output unit is provided for signaling any deviation of the actual value from the target value of the training load value from the performance profile. Thus, an entire training session can be carried out without external sensors, and the person training receives a notification via the output unit that the training must be adjusted to achieve the target value. In one embodiment, the output unit is designed as a screen; this makes it easier for the person training to understand and accept instructions given by the training device. In another embodiment, the output unit can emit acoustic signals. The two aforementioned embodiments can be combined.
[0011] To achieve the desired training effect, the control system for changing the speed and / or resistance is designed to adapt the performance based on the performance profile. In a further embodiment, the training device can be assigned a measuring system designed to monitor the physical exertion of the exerciser when the initial exertion level is reached. This measuring system can be designed to record heart rate and / or oxygen consumption and serves to safeguard the use of the Borg scale as a redundant control instrument that does not need to monitor the entire training session, but only warns when limit values are reached.The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figure, can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also considered to be encompassed and disclosed by the invention that are not explicitly shown or explained in the figure, but which emerge and can be produced from the explained embodiments through separate feature combinations.
[0012] Further advantages, features, and details of the invention will become apparent from the claims, the following description of preferred embodiments, and the drawings. Herein:
[0013] Figure 1 is a perspective view of a training device,
[0014] Figure 2 shows the individual perception of exertion according to the Borg CR10 scale for individuals with different performance levels, and
[0015] Figure 3 shows a time-dependent performance profile
[0016] Figure 1 shows a training device 1 in the embodiment of an ergometer, which is suitable for training both the arms and the legs and has a pivoting unit 3 with forced coupling for changing the extremities to be trained, although the training device can also be formed by embodiments of a treadmill, a stepper or a rowing machine not shown in the drawing.
[0017] The training device 1 is assigned a measuring system for recording the performance provided by a trainee and a control system with an input channel for recording a load value and an output channel for specifying the performance to be provided, wherein the control system is set up to carry out a method comprising the steps of: a) specifying an initial load value, b) recording the value of the performance provided when the initial load value is reached, c) transferring the value of the performance provided via the input channel d) calculating the performance to be provided for a training load value depending on a scale for personal perceived load and outputting it via the output channel.
[0018] The scale for the perception of physical exertion can be given by a Borg scale, in particular by the Borg CR 10 scale and / or the Borg CR 20 scale.
[0019] The Borg scale is a scientifically well-researched scale for determining the human load based on the subjective perception of exertion (Fig. 2). The current, linearized Borg CR 10 scale is as follows:
[0020] • 0 = no effort at all
[0021] • 0.5 = very, very mild (barely noticeable)
[0022] • 1 = very mild
[0023] • 2 = mild
[0024] • 3 = moderate
[0025] . 4
[0026] • 5 = difficult
[0027] . 6
[0028] • 7 = very difficult
[0029] . 8
[0030] 9
[0031] 10 = extremely difficult (almost maximum)
[0032] The Borg scale establishes a linear relationship between perceived exertion, heart rate, and individual exertion. Figure 3 shows the individual perceived exertion for individuals with varying levels of performance. Values 0 to 2 on the Borg scale correspond to recovery, intervals 2 to 3 correspond to low exertion, intervals 3 to 5 to moderate exertion, intervals 5 to 7 to high exertion, and intervals 7 to 10 to maximum exertion. The following table provides a further scaling of the values according to the historically oldest scale, the Borg CR 20 scale, which, like other exertion scales, can be converted into the current Borg scale:
[0033] The table also shows a linear relationship between the Borg scale values and heart rate. The perceived exertion is assigned to the right column, so that here, too, a conclusion can be drawn about a corresponding value on the Borg scale based on the subjective perceived exertion.
[0034] Figure 3 shows an exemplary time-dependent power profile, which is specified by the control system in a step e).
[0035] The graphic shown in Figure 3 represents, by way of example, the target values of the training load value at any time during the training session. An output unit is provided to signal a deviation of the actual value from the target value of the training load value. In the present invention, this output unit is embodied as a screen 2. In other embodiments, an acoustic signal and / or a vibration signal can also be provided for signaling, optionally in addition. The control system of the training device 1 is designed to change the speed and / or the resistance to adapt the performance from the performance profile. The training device 1 also has a measuring system for monitoring the physical load of the trainee when the initial load value is reached. The measuring system is designed to record the heart rate and / or oxygen consumption.
