Description

Method for operating a training device and device for recording body functions for use with a training device

The invention relates to a method according to the preamble of claim 1 for operating a training device for muscle training a person and / or for checking the muscle performance of a person. Furthermore, the invention relates to a device for recording body functions, in particular for use with a training device which is to be operated according to the method according to the invention.

Training devices, such as exercise bikes, elliptical trainers, rowing machines and the like, with which muscles of a person are to be trained or whose muscle performance is to be checked and recorded, must be designed in such a way that they can be used by as many different groups of people as possible, which differ with regard to their body-specific properties, such as gender their body height and mass, their age or their physical constitution, can be used. However, the variety of possible users of such training equipment also means that individual training sequences and maximum loads must be specified for each group of people in order to ensure that the muscle load is as gentle as possible. To ensure this, displays or tables are usually provided on the control devices of the training devices, which give the person exercising in each case behavioral rules and instructions for gentle training. It is also known to record the heartbeat frequency of the exercising person during the training and to display it on the training device so that the exercising person can adapt their training to the current physical situation. The success of the training, however, depends to a large extent on the person training and their willingness to observe these behavioral rules and instructions.

It is the object of the invention to provide a method for operating a training device or a device, in particular for use with a training device, in which or when using an extremely gentle muscle training. ning and / or an extremely gentle examination of the muscular performance of a exercising person is possible.

The invention solves this problem by a method with the features of claim 1 for operating a training device for muscle training of a person and / or for exercising the muscular performance of a person. Furthermore, the invention achieves the object by a device with the features according to claim 11 for detecting body functions, which should be particularly suitable for use with a training device.

According to a first aspect, the invention relates to a method for operating a training device for muscle training a person and / or for checking the muscle performance of a person. Such a training device is equipped with at least one training device which is acted upon by linear forces and / or torques against which the person trains with muscle strength. An essential idea of the method according to the invention is based on the approach of taking into account the body-specific properties of the exercising person, such as, for example, their body height or body mass or their training status, when controlling the training facility. For this purpose, it is proposed in the method according to the invention that the control device controls the training device based on body-specific data records of the person exercising and, taking into account the properties of the training person specified in the body-specific data records, varies the linear forces and / or torques generated by the training device. By taking into account these body-specific properties of the exercising person, the exercising person can be gently introduced to their performance limit for optimized muscle training.

Further advantageous developments of the invention result from the following description, the subclaims and the drawing. In a particularly preferred method variant, it is proposed to read the body-specific data records from a storage medium into the control device of the training device. The storage medium can be provided directly on the training device, so that, for example, by actuating a pressure switch assigned to the training person on the control device, the data records stored in the storage medium are called up and read into the control device. As an alternative or in addition to the internal storage medium, it is possible to use an external storage medium, for example a chip card or a USB memory stick, on which the body-specific data records assigned to the respective person or groups of people are stored, and this via a reading device or a suitable one Interface for the transmission of the data records is to be connected to the control device. Furthermore, it is possible to enter the body-specific data sets directly into the control device via an input unit.

The body height, body mass, age, training status, training procedures and / or the health status of the person exercising in each case are used as body-specific data sets for controlling the training facility. Furthermore, it is proposed to read in or save a seat position optimized for the respective person with regard to ergonomic and orthopedic aspects for the respective training device as a body-specific data record in the case of exercise bikes and rowing machines. If the training device is equipped with appropriate actuators, for example to adjust the seat or saddle height, the seat or saddle inclination and the fork height, the seat or saddle and the fork are placed in positions that and arm lengths and the length of the torso of the person exercising are optimally adapted.

In a particularly preferred variant of the method according to the invention, it is further proposed that the control device at least temporarily control the training device as a function of at least one body function detected on the person. In this way, a control loop is formed in which the linear forces and / or rotary forces generated by the training device of the training device Moments against which the person is training are adapted to the current body condition of the training person, whereby the body-specific data records for the training person are also taken into account, so that a training process optimized to the individual body properties of the training person while taking into account the current load state of the person is automatically specified by the training device.

In this variant of the method, it is further proposed to detect the at least one body function directly on or near the carotid of the person, to determine evaluation data based on the detected body function and to transmit it to the control unit, so that the control unit uses the evaluation data to determine the linear forces and / or Torques generated by the training facility are changed. By recording the at least one body function directly on the carotid of the person, a very precise recording of the body function is possible. Tests have shown that, for example, when measuring the heartbeat rate in the carotid region in a relatively simple manner, not only the heartbeat rate but also the timing of the heartbeat, i.e. the systole and the diastole can be determined very precisely. Furthermore, a determination of the blood oxygen or lactate level that is sufficient for the normal training is possible without any problems, for example by using a photometric measuring method.

Furthermore, ^" it is possible to record two bodily functions at almost the same place on the carotid body of the person, these two bodily functions possibly being related to one another, for example the lactate level and the heartbeat rate. This enables even more precise control of the training device , while a check of the recorded bodily functions is possible, for example, high-performance athletes usually have very large ventricles, so that even with a single heartbeat large amounts of blood are transported through the circulation, with the result that the pulse rate even with a comparatively high physical load increases only slightly. If, in addition to the heartbeat frequency, the lactate level or, for example, the blood oxygen is also recorded, the heartbeat frequency can be compared with the lactate level or the blood oxygen, so that, for example, if the lactate level increases disproportionately, it can be assumed that despite one compared to an average trained Person trained only a small increase in the pulse number of high-performance athletes in anaerobic, ie oxygen-free training state, which would be counterproductive for endurance training. In particular, by taking the training state into account as a body-specific data set, an optimized training sequence can be specified by the training device with the aid of the relationship between different body functions mentioned above.

In a particularly preferred modification of this method variant, it is therefore proposed to record the lactate level and / or the blood oxygen and / or the heart rate and / or the blood sugar level and / or the body temperature as a body function.

Since the ability to train depends on the individual body characteristics of the person training, it is also proposed to define maximum permissible limit values for the relevant body function based on the specified body-specific data records. These limit values can then be used, for example, to reduce the linear forces and / or torques generated by the training device to such an extent that the body function detected in each case exceeds the maximum permissible limit value assigned to it, in order to avoid overloading the exercising person.

In this variant of the method, it is particularly advantageous if the limit values are set such that the linear forces and / or torques against which the person in question generates the aerodynamic muscle training for the person in question. This is particularly advantageous if the training device is to be used as an endurance training device. If the exercising person, for example a high-performance athlete, wants to consciously carry out anaerobic muscle training, the maximum permissible limit values can be changed so that an anaerobic muscle training that is still compatible with the body is possible, but muscle strain is avoided.

In a particularly preferred modification of the method according to the invention, the body mass and the body height, optionally the degree of athleticism and / or also the age are specified as body-specific data records. In particular, the relationship between body mass and body height defined as body mass index (BMI) can be used as a body-specific data set. The control device is then equipped with a corresponding database, in which, depending on the body mass index and other body-specific data records, such as the level of sportiness or age, predetermined ranges of the heart rate, ranges for the lactate level or the blood oxygen, in tables are filed. As soon as the body-specific data records have been entered into the control device via a suitable medium, for example an input keyboard or a storage medium, the control device automatically searches for the optimal ranges for the respective person for the values of the relevant body function, on the basis of which the further regulation of the body function Training device follows. In these

Tables can be stored, for example, age-dependent maximum permissible limit values for the pulse, the lactate level, the blood sugar level and the like. The latter is particularly important when a person suffering from diabetes is exercising in order to signal to the person the risk of hypoglycaemia during exercise.

Furthermore, in a particularly preferred method variant, it is proposed to record the relevant body function as a course based on time and to record the person's training behavior as a body-specific data record as a function of the temporal course of the body function. For example, as previously explained, it has been shown that high-performance athletes in proportion to less trained people, despite high physical exertion, show relatively low pulse rates at the heartbeat rate, so that when the heartbeat rate is recorded, the limit values for the heartbeat rate that would normally be specified would be unsuitable. In this case, if the heartbeat frequency has been recorded as a course of time in accordance with a predetermined training program, for example in the case of a top athlete, an individual limit value can be determined for this person. In the same way, it is possible to record the training behavior of a person, so that, for example, a training behavior that would be more damaging to the body is determined by recording the chronological course of the body function concerned in each case and the training device of the training device is targeted in order to avoid a possibly excessive load can be reduced.

Another aspect of the invention is based on the idea of specifying a device with which a wide variety of bodily functions can be recorded precisely and without great effort by a training person and used to optimize body training.

In order for people to be guided to their performance limits as gently as possible during muscle training or when checking their muscle performance, people increasingly wear devices during training with which the heart rate can be recorded as a body function. The detected heartbeat frequency is then forwarded to an evaluation unit, which, for example, determines the current pulse number of the exerciser from the sensor signals and displays this on a display unit.

Such a device is known for example from DE 42 41 336 AI or DE 42 15 549 C2. In these known devices, the exercising person wears the sensor unit for detecting the heart pulse with the aid of a chest belt directly in the area of the heart. The heartbeat rate recorded by the sensor unit is transmitted to an arm via a transmission unit which is also integrated in the chest strap. a clock-like evaluation unit transmitted by radio signals. The evaluation unit then determines the current heartbeat frequency from the transmitted sensor signals, which is indicated in a display unit as a numerical value.

These devices known from the prior art are only able to detect the heart rate. Other body functions, such as the lactate level, the blood oxygen, the blood sugar level or even the body temperature, cannot be recorded, in particular in the area of the chest where the sensor unit is held by the chest strap. For example, the lactate level or the blood oxygen is only arranged on a surface close to the skin

Artery in a simple way, i.e. bloodless to certain. Furthermore, the heartbeat frequency detected by the sensor unit is also not sufficient for precise control of a training device in order to specifically control the training device of the training device that generates linear forces and / or torques against which the person trains with muscle strength, according to the actual training state of the training person ,

An essential approach of the device according to the invention is based on recording body functions of the exercising person at a point which is easily accessible on the one hand, while on the other hand it provides a relatively exact measurement of a wide variety of body functions such as lactate level, blood oxygen, heart rate or blood sugar level. allows. For this purpose, it is therefore proposed to record at least one of these bodily functions on the neck of the person, namely directly on or near at least one of the two carotid arteries, that is, the carotid arteries of the person. Experiments have shown that, for example, when measuring the heartbeat frequency in the area of the carotid artery, not only the heartbeat frequency but also the timing of the heartbeat, ie the systole and the diastole, can be determined in a simple and very precise manner. It is also possible, for example, to determine the lactate level with sufficient accuracy for normal training by using a photometric measuring method. These were detected directly on or near the carotid artery Body functions can then be transmitted to an evaluation unit, which generates evaluation data based on the sensor signals of the sensor unit, which can be used, for example, to control the training device on which the training person is currently training. In the device according to the invention it is therefore proposed to provide at least one sensor unit and the transmission unit with which the sensor signals are transmitted to the evaluation unit on a carrier collar which the training person wears on the neck during the training in such a way that the sensor unit applies the body function to be detected or near the carotid. This enables the body function to be monitored to be detected in a simple manner with relatively simply constructed sensor units, the sensor signals representing the current body function being so accurate due to the measurement on the carotid that they are sufficiently high for the optimization of the training sequence of a training device, on which the person can be trained, used. With a corresponding technical design, it is even possible to increase the sensitivity of the sensor unit so that the generated sensor signals can also be used for rehabilitation purposes or for checking the performance of the exercising person.

Thus, in a particularly preferred embodiment of the device according to the invention, it is proposed that the device as a body function detect the lactate level and / or the blood oxygen and / or the heart rate and / or the blood sugar level and / or the body temperature. By determining the lactate level in the blood, the current training status of the exercising person can be inferred directly. The concentration of the lactate, which is a metabolic waste product that is released from glucose during anaerobic energy production and acidifies the muscles, provides immediate information as to whether the exercising person is still training in the aerobic training area or whether the exercising person is already giving up the anaerobic energy production is dependent on which glucose is broken down. The blood oxygen, ie the oxygen saturation in the blood, indicates the percentage of oxyhemoglobin in the total concentration of hemoglobin in the blood. In this way it can be determined to what extent the exercising person is able to store oxygen in the blood, which is particularly important for endurance training. The determination of the heartbeat frequency is also of great importance, since the number of heartbeats gives an immediate indication of the stressful state of the exercising person. In addition, by measuring the heartbeat frequency directly on the carotid, it is also possible to determine the course of the heartbeat frequency, ie the systole and diastole of the heart, which enables a very precise determination of the current stress on the heart during training. The measurement of the blood sugar level is also important, since glucose is only broken down during anaerobic energy production. Furthermore, the body temperature of the exercising person can also be recorded, since the body temperature gives an immediate indication of the current exercise condition of the exercising person.

A photometric sensor unit can be used to detect the lactate level, the heartbeat frequency or the blood oxygen, in which light with a predetermined wavelength range is guided through the tissue to be examined and is detected after penetrating the tissue, the changes in the wavelength ranges after passing through the tissue Immediately indicate the lactate concentration or the oxygen saturation of the blood, while the fluctuations in the sensor signal allow conclusions to be drawn about the heart rate.

A photometric sensor unit, which has several, is particularly preferably used

Can record body functions at the same time, for example the lactate level and the heartbeat frequency, the blood oxygen and the heartbeat frequency, or the lactate level and the blood oxygen.

In a preferred embodiment of the device according to the invention, the use of an iontophoretic sensor unit is used to detect the blood sugar proposed in which, with the aid of two electrodes placed on the skin, the blood sugar level is determined by applying a voltage to the electrodes, which causes ion migration in the skin. The positively charged sodium ions migrate together with the blood sugar to the negative electrode, while negatively charged chlorine ions migrate to the positively charged electrode. By calibrating beforehand, the blood sugar level can hereby be determined and the training person's blood sugar level can be inferred directly. The process described above is reversed by reversing the polarity.

Furthermore, it is proposed to use a temperature sensor unit for detecting the skin surface temperature, which unit works, for example, with a semiconductor sensor.

The measurement signals can be transmitted, for example, by a cable which forwards the sensor signals from the transmission unit to the evaluation unit. The transmission unit is particularly preferably designed for transmitting and receiving electromagnetic waves, so that the sensor signals and possibly control signals in the form of radio signals can be transmitted to or received by the evaluation unit. This is particularly advantageous if the exercising person wants to move relatively freely during the training. It then only has to be in the transmission and reception area of the evaluation unit.

In particular, if a plurality of sensor units are provided on the carrier collar of the device tone according to the invention, it is particularly advantageous if the transmission unit has a control for actuating the sensor units, which, for example, independently activates or, if appropriate, also switches off the sensor units correspondingly received control signals.

The evaluation unit of the device is preferably connected to a control device of a training device, so that those emitted by the device Sensor signals that indicate the detected body functions can be fed directly into the control device of the training device by the evaluation unit. This is particularly advantageous if the sensor signals are also used to control the training device.

The carrier collar can be designed as a separate accessory that is put on by the exercising person during each training session. Alternatively, it is also possible to integrate the carrier collar into a piece of clothing. The carrier collar can, for example, be incorporated into the collar of a T-shirt or a sweatshirt, so that when the person exercising is just putting on the item of clothing, the device tone for registering the body functions is properly put on.

The invention is explained in more detail below on the basis of an exemplary embodiment with reference to the drawing. It shows:

Fig. 1 is a perspective view of a device according to the invention for detecting multiple body functions, and

Fig. 2 is a schematic side view of a training device that can be used together with the Vorrichtong of FIG. 1.

1 shows a perspective view of a device tone 10 for detecting various body functions, namely for detecting the lactate level, the blood oxygen, the heartbeat frequency, the blood sugar level and the body temperature.

The device 10 has a carrier collar 12, which is made of a supple, comfortable material, for example a fabric material or a soft plastic material. The carrier collar 12 is placed around the neck 14 (shown in dash-dot lines) of the exercising person and closed with the aid of a closure 16, which is designed, for example, as a Velcro fastener, in a position which is comfortable for the person to wear. A transmission unit 18 is held on the carrier collar 12 and is largely embedded in the material of the carrier collar 12. The transmission unit 18 is connected to a plurality of sensor units 20, 22, 24, 26 and 28 for signal transmission. The sensor units 20, 22 and 24 are photometric sensor units which are used for various purposes. Depending on the respective application, the sensor units 20, 22, 24 and 28 are arranged in the immediate vicinity of the two main arteries 30 and 32 (also shown in dash-dotted lines) when the carrier collar 12 of the device tone 10 is properly applied.

The photometric first sensor unit 20 is used to detect the lactate level in the blood, in which light is guided along the surface of the carotid 30 and then recorded, the lactate level depending on the wavelength changes that the light experiences when passing through the edge region of the carotid can be determined from the sensor signal of the first sensor unit 20. The photometric second sensor unit 22 is based on the same mode of operation and detects the heartbeat frequency, whereby not only the pulse beat but the entire course of the heartbeat frequency over time, i.e. systole and diastole. The third sensor unit 24 is also a photometric sensor unit in which the content of blood oxygen in the blood of the carotid 32 shown on the right in FIG. 1 is detected with light.

The fourth sensor unit 28 is an iontophoresic sensor unit with which the blood sugar value can be determined. For this purpose, the iontophoretic sensor unit 28 is equipped with an anode 34 and a cathode 36. By applying a low voltage between the anode 34 and the cathode 36, the sodium ions and chlorine ions contained in the tissue are stimulated to migrate between the two electrodes 34 and 36, the positively charged sodium ions migrating to the negative cathode 36, while the negatively charged chlorine ions to migrate positively charged anode 34. Since the blood sugar molecules have the property If they migrate together with the sodium ions, they also reach the cathode 36, as a result of which the blood sugar values can be determined directly. This process is reversed by reversing the voltage.

Furthermore, a temperature sensor unit 26 is arranged between the two pairs of sensor units 20 and 22 or 24 and 28, which uses a semiconductor sensor to detect the surface temperature on the skin of the person exercising.

The body functions detected by the sensor units 20 to 28 are sent to the transmission unit 18 in the form of sensor signals via fine conductors, not shown. The transmission unit 18 is designed for transmitting and receiving electromagnetic waves 38 and is in radio communication with an evaluation unit (not shown) of a training device 40. The structure of the training device is explained in more detail below with reference to FIG. 2.

The training device 40 is a so-called elliptical trainer. The training device 40 has a frame 42 on which a training device tone 44 is provided. The training device tone 44 is connected to a control device tone 46 and is actuated by the latter so that the training device tone 44 generates a braking torque which counteracts the muscular strength of the exercising person, as will be explained later.

The training device 44 has a flywheel 48, on each side of which a pedal 50 is articulated with one end on both sides, eccentrically and offset by 180 ° in the direction of rotation. The other end of the pedal 50 is coupled to a pivot bearing 52, with which the respective pedal 50 is connected to a lever 56 provided on the frame 42 and pivotably mounted on a second pivot bearing 54.

For training purposes, the exercising person stands upright on the two pedals 50, moves them back and forth in an approximately horizontal direction, while simultaneously pressing them the two levers 56 pulls or pushes. In this way, the flywheel 48 is set in motion, which is coupled to a braking device arranged in a housing 58 of the training device 40. The brake device tone of the training device 44 is connected to the control device tone 46, the control device varying the braking torque generated by the brake device tone and acting on the flywheel 48 in accordance with predetermined training programs.

The control device 46 in the training device 40 according to the invention is additionally equipped with the evaluation unit (not shown), which detects the electromagnetic waves 38 emitted by the transmission unit or transmits corresponding control signals in the form of electromagnetic waves to the transmission unit 18.

After the training device 40 is switched on, the control device 46 first generates body-specific data records of the exercising person, namely the body mass, the body height, the training state, i.e. the level of athleticism and the age, read from a storage medium or entered into the control device 46 by the exercising person. The individual body-specific data records are compared with predetermined reference data records that are permanently stored in the control device 46. Depending on the body-specific data sets and the selected training process that the person training should take, the maximum permitted limit values for the heart rate, blood sugar level, lactate level, blood oxygen and body temperature are then selected from the reference data sets.

After the exercising person has properly put on the collar 12, as shown in FIG. 1, activating the training device 40 transmits a corresponding switching pulse from the evaluation unit to the transmission unit 18, which in turn activates the sensor units 20 to 28. Depending on a measurement cycle specified by the control device 46, the various body functions, such as the Lactate levels, the blood oxygen, the heart rate, the blood sugar level or the skin surface temperature, continuously (e.g. heart rate) or intermittent (e.g. blood sugar level) recorded and transmitted in the form of sensor signals from the transmission unit 18 to the value unit. Evaluation data is generated in the evaluation unit as a function of the detected sensor signals and is subsequently compared with the predetermined maximum permissible limit values in the control device 46.

As has already been explained, these predefined maximum permissible limit values are based on the predefined body-specific data records of the exercising person, which were previously input or read into the control device 46. The maximum permissible limit values are dimensioned such that the person concerned performs aerobic muscle training if these limit values are observed in order to achieve maximum fat burning. If desired, the limit values can, however, also be specified so that an anaerobic muscle training is carried out in a targeted manner.

In order to achieve this, the previously mentioned body functions are recorded continuously or intermittently with the aid of the device tone 10 according to the invention and compared with the predetermined maximum permissible limit values. As soon as one of the body functions exceeds the maximum permissible limit value assigned to it, the control device 46 reduces the braking torque generated by the brake device so that the exercising person has to exert less force for the training and thus the load on the person is lower. In this way, the entire training process is continuously monitored and the training device is adapted to the individual and current performance of the exercising person in accordance with an optimal training result.

After the end of the training, the limit values stored in the control device 46, the training process and the various body functions recorded can be stored individually for the person in the storage medium, whereby changes in the body-specific data records can also be saved.

The body-specific data records can also include fixed predetermined limit values for certain body functions as data records that should not be changed.
