Description

The present invention relates to devices and methods for measuring and supporting exercise performance in weight-based fitness equipment.

The training methods to increase physical well-being, general fitness and competitive sports are subject to constant change. This is due to new medical findings, more modern sports and exercise equipment and not least to new trends. The inclusion of the training results to assess the current performance and the individual level of performance, however, has always existed. Times, heights and distances were measured, weights weighed, repetitions counted. The results were translated into training logbooks and meticulously tracked. The inclusion of medical data such as pulse control, heart rate measurements, lactate levels, blood sugar levels or other indicators that provide information on body condition and functioning has been increasingly practiced in recent years. The more often, the easier and easier this data could be measured. Nowadays many smartphones already have an application that offers help.

The recording, archiving and evaluation of this data is done digitally, directly on the application device or the archiving and evaluation takes place after transmission of the recorded data on a terminal. Now it is clear that more accurate and more precise data can lead to better evaluations. Unfortunately, it is the case today that even in the fitness centers there are training devices that can specifically address and train all muscle groups, but these devices do not record the training data, if at all, as precisely as is desired for evaluation purposes. Thus, although the applied force can be measured in certain devices, the detection of the movement, in particular the recording of fast movements, is not possible. Nowadays, spring systems which measure the respective tension or tensile force and ultrasound-based measuring systems are used.

It is therefore the object of the present invention to provide devices, methods and the resulting applications which make it possible to record the training services on a large number of training devices and to provide them for further processing.

This object is achieved by a device for measuring training data, in particular data for determining the force to be applied, the repetition of exercises and the speed of execution of the exercise, said device is mobile and at least a part is connected via a holding means so with the exercise device, in that a measuring module can receive the data, and wherein this device has a measuring module which obtains the data optically, in particular with the aid of a laser.

The advantages of the optical measurement methods are well known and provide a very high accuracy in the measurements, the measurement results are available immediately. So the speed controls of the police, as surely everyone knows, are already possible today with so-called laser pistols. This field of application shows the accuracy and the unassailability of the measurement method for location and speed measurements.

The basic principle of the optical measurement method is based on a temporal light pulse, which is emitted and reflected back to the source. From the pulse duration, it is easy to determine the distance between the source and the object, since the speed of the light is known.

Such an optical distance measurement can be used to determine the initial state and thus the weight used. The light source, ie the device or the measuring module is attached to the training material to be moved. Preferably, the training material is a stack of plate-shaped weights, which must be moved in whole or in part by the exerciser. The trainee can adjust how much of these weight plates he wants to move. This he accomplishes by fixing the plate stack to the unit to be moved, namely a rod (weight lifting rod) or a cable or the like. The fixation is done in most cases by a plug-in system that connects plate stack and unit with the help of a pin. The distance to be measured is by a well-defined distance to a non-moving point (location), which is located on the ground, on a wall or preferably on the training device itself. If the distance between the source, ie the measuring module and a certain point (location), which is located on the training device, so only a one-time calibration of the system is necessary. The respective measured distance is assigned to the respective weight. Thus, the determination of the weight is guaranteed.

The frequency of repetition can be determined by a movement analysis of the object to be moved, in particular a weight. A lifting or lowering of the weight is always with the reversal of the Movement direction connected. Similarly, sideways, oblique and all other directions of movement are detected. By counting the movement direction changes, the repetitions can be determined.

Additional motion sensors provide more (even spatial) motion position information per time interval with less power consumption than the laser measurement unit. However, these sensors can only provide relative movement / position information as a matter of principle and must therefore be regularly referenced with the data of the laser measuring unit. As a result, for example, movements can be logged more finely.

The speed with which the training object is moved is easily determined by a continuous distance measurement. A centimeter-accurate resolution of the distance is easy to achieve with this method. In this order of magnitude is therefore also the value of the speed to find, since this can indeed be calculated from the distance data.

A preferred embodiment of the present inventive device is characterized in that it comprises an input / receive / transmit / store module arranged to receive, retrieve, preferably receive information about the geometry of the exercise devices and / or the exercise scope or can be sent. With the help of this input / receive / transmit / memory module, information about each existing exercise device can be obtained. The data is either transmitted and / or stored in stored form in the module. If desired, they can only be left in the module. Thus, since the device can be customized for each device, it can be used with most devices. Their size and mobility also allow retrofitting on most exercise equipment. It should of course be noted that the exercise has a movable component, so a part of the training device must be moved. But this is given in almost all engines, so exercise equipment for muscle strengthening with the help of weights.

In another preferred embodiment of the invention, the retaining means is a pin, preferably in the form of a weight bolt, which is usually used in most engines for locking and adjusting the weights. This weight bolt (pin) is mechanically connected directly to the measuring module. The lifting of the weights and the associated movement is thus made by the measuring module, as well as the bolt (pin). This embodiment simplifies the retrofitting of conventional sports equipment already in circulation with the measuring module. There is no mounting necessary. All you have to do is replace the bolts. Here are several other interesting embodiments conceivable. In the first variant, the bolt remains on his training device (stationary variant). The trainee then has to register for the desired exercise. This can for example be done automatically via a non-contact communication device. The input / receive / transmit / store module is informed of the presence of the respective exerciser by a carrying transmitter module, possibly an RFID chip card. This can also be triggered by an action. Thus, holding the chip card to the input / receive / transmit / memory module or a manual input are possible. In the other case, however, each trainee can also carry his own measuring device which is specially set for him (mobile variant). The device then also automatically detects the respective user.

The input / reception / transmission / memory module should not only serve the input of data, preferably via a device located on the touch display and the output of the received data on the display, it should also pass the data to external devices with its transmission function who can evaluate and process this data. Of course, the data can also be stored in the memory module. Here are also other options very beneficial. As mentioned above, a personalized meter can be assigned to exactly one person or manage multiple user profiles. This person may have bought, rented or otherwise obtained the measuring device for personal use. Since the device according to the invention is mobile, i. can also easily be carried in a sports bag, the owner or the owner of the meter is not bound to a specific gym or training device, but can use anywhere his meter where the appropriate exercise equipment available (mobile variant). This is now possible, as already mentioned above, almost everywhere on all devices, since the weight bolt is normalized and the pin of the device according to the invention has exactly these dimensions.

Sharing or using the measuring device of several practitioners is also easily possible. In this case, each user gets his own identifier that the device must be notified or even recognizes, based on an identifier of a smart card, a smartphone or a cipher during anonymous training. The measuring device can therefore be assigned to the respective device and / or belong to one or more users. The Data can be personalized or recorded anonymously. This is all set with a certain programming effort. In the simplest case, an anonymous user trains on a device with a stationary, ie there remaining measuring device. Then he can see his data on the display. He can have it saved under an anonymous cipher and after training, all the data he has received on the devices can be transferred to a terminal, such as his cell phone or another. From this a personal training diary can be created. The data can be compared and evaluated, averaged or graphically output.

The anonymous evaluation of all training data of all users is also possible after they have been collected and transferred to a terminal. This allows the utilization of the individual devices to be determined and trends to be determined. General statistical evaluations may use differential privacy. Differential Privacy is used in the context of publishing sensitive information. On the one hand, one would like to make general, statistical information publicly accessible, but at the same time preserve the privacy of the individual participants. One conceivable scenario is the publishing of training behavior data within a gym to allow researchers or other groups to uncover statistical relationships. It is necessary to edit the data so that tracing back to the trainee is not possible. For these research purposes it is sufficient that the statistical distributions in the published data correspond to those of the real data, the personal characteristics of the exercisers do not matter.

It can also be monitored in addition to the speed and movement. So the proper execution is checked. This can be done by tracking once or by comparing with the default. In addition, an individual permitted deviation can be taken into account. Surveillance can help beginners perform the exercise exactly. An interface to the trainer, which of course is optional, provides useful information for the user / trainer conversation. Information such as the execution monitoring, but also which exercises (with sentence and repetition information) were collected over the current training period are transmitted.

Interfaces to third-party providers are also conceivable. These interfaces are used for data exchange to be able to use already in use programs and apps for training support together with the bolt. The handling of these programs is simplified in combination with the bolt, because certain training data does not have to be entered manually. Thus, for example, already existing on the market activity tracker (bracelets) more information (pulse, movements of the trainees, etc.) record and tell the bolt, which can then process and further process. By combining with such a bracelet an automatic login and logout would be possible because a connection of the data can be established. Also a calorie indication serves for the comparison with the training instruction. The calculation of calories is usually done by the MET method. A MET (Metabolic Equivalent) is defined as oxygen uptake when sitting. The metabolic equivalent assumes a linear relationship between calorie consumption and oxygen uptake for approximate calculation. The deviations of about 5 percent can be neglected in our application.

Based on this teaching, the device can be connected to a basic server, which receives and processes the data of at least one device and / or processed and ultimately stores. The preparation of the data of several users can then be evaluated, averaged or graphed just like the individual data. This can be done for information, training or competition purposes. The output can even be switched to a large monitor for all, so that interested training colleagues can admire the achievements. The measuring system resulting from measuring devices and basic server can increase the motivation of the exercisers. As receiving units, almost all devices to be controlled with software, such as smartwatches, smartphones, tablets, fitness bracelets, chest and arm straps or the like are suitable because they can receive measurement data from the measuring device. Of course, these electronic systems can also transfer data to the measuring device. The base server can be any conventional electronic data processing unit, it only has enough power, storage space and the necessary software programs.

In another embodiment, a server is not necessary as a terminal, since the measuring device according to the invention is connected to every other present (possibly even exclusive) measuring device via a Bluetooth scatternet topology. Here, all data is shared and exchanged through networking. There is no complex infrastructure necessary, especially no Wi-Fi. This is a great advantage because not every gym has enough WiFi infrastructure.

Since sensitive personal data can be present on the measuring instruments, they should be physically secured in the stationary version. For example, via a metal band (Kensington fuse) on the guide rod of the weights, by a known from the retail anti-theft device (electronic article surveillance) at the entrance of the gym, if someone accidentally forgot to return a measuring device according to the invention or of course by an optional password protection entered on the display must become. The fact that the measuring device is unusable outside a suitable scatternet offers additional protection.

In a further embodiment of the present invention, the motivation of the exercisers is promoted via the gamification approach.

Gamification describes the approach of typical games in non-gaming environments. The aim is to influence the behavior of the users. Empirical studies show that gamification can contribute to the fulfillment of motivating psychological basic needs and promote the quality and quantity of the service provided. Gamification has long ceased to be a fashion concept. We encounter approaches to gamification on a daily basis. Probably the most well-known example of gamification, the collection of Payback points can be mentioned. Here, points are collected while shopping, which can be exchanged for rewards. Collecting bonus miles for frequent flyers or even competitions that work with codes on the bottle cap are examples of gamification in everyday life. Certainly, one could continue the list of everyday rooted gamification as desired.

In our case the gamification serves to increase the motivation of the exerciser. These added values are generated virtually by the trainee through physical training and the simultaneous tracking by our bolt (the device according to the invention) and displayed visually on the terminal (display of the bolt (of the device according to the invention), smartphone).

It should be said that our gamification elements offer both real added value and motivational virtual added value. For most gamification elements, the user has the opportunity to participate anonymously. No personal data is collected here. Even if no rewards and / or points can be collected in this variant, the user can be displayed whether he won or lost. As already mentioned, the motivation of the exerciser is in the foreground.

1. 1. die Killer (hier steht das Siegen und der Wettkampf im Vordergrund)
2. 2. die Achiver (hier steht das sammeln von Punkten, Auszeichnungen, Awards und Rewards im Vordergrund)
3. 3. die Socializer (hier steht die soziale Anerkennung im Vordergrund)
4. 4. die Explorer (hier steht das sammeln neuer Eindrücke als auch das lernen im Vordergrund)

But what motivates the trainee, can be differentiated in terms of gamification specifically about 4 motivational categories. There are the following classifications:

1. 1. the killer (here the winning and the competition is in the foreground)
2. 2. the Achivers (collecting points, awards, rewards and rewards)
3. 3. Socializers (social recognition is the main focus here)
4. 4. the Explorer (here is the collection of new impressions and learning in the foreground)

The individual gamification features can now be assigned to the 4 motivation categories mentioned above.

Killer:

• - Competitive mode against all or against selected friends (who creates more weight or repetitions on the same device? → Conversions possible, so that competitions with unequal opponents are possible and fun)
• - Challenges can be created by the trainees themselves. (For example, Brustpresse, who creates the most repetitions? → Prices and "punishments" can be set in the battles of the trainees themselves (loser pays the next shake, etc.))
• - Who burns the most calories?

Achiver:

• - Rewards (and punishments) take place through bonus points or point deduction
• - Points can be given away and exchanged.
• - Who burns more calories gets extra points
• - Points can be redeemed in coupons etc.
• - Rewards: These can of course be provided by the studio operator himself. In addition, it will be possible through money deposits, through regular training tracked by our bolt to earn money. Paid by members who do not train regularly (about membership fees). Members can voluntarily and optionally engage in weekly target agreements. The bolt tracks the results through valid and non-fake data Writes the members who made the deal well, the money collected through the broken deals. Other deals can be concluded, for example, with cooperation partners such as health insurance funds, who have an interest in valid data and are also interested in members regularly going to the gym and issuing rewards.

Social:

• - GPS / WLAN detection when entering the studio. Friends, training partners are informed via push notification
• - Share your calorie consumption on Facebook and get bonus points
• - Social Media: Trainers can share any results directly on social media and report their success and invite Facebook friends to play (live in the studio)

Explorer:

E-learning aspects ensure that even Explorer enjoy the gamification. In this case, for example, the human anatomy can be displayed on the display, with the user having to tap on the muscle to be trained on this device. ( 4 ) Here also the degree of difficulty can be extended and completed in level. The next time he trains on the same machine, he does not have to tap the muscle but name it, and so on.

Thus, the trainee is gradually supplied with knowledge, which helps him to optimize his training.

If you take a closer look at the 4 mentioned classifications, you will notice that many gamification features belong to several motivational categories, as the features simultaneously satisfy several needs of different types of players. Thus, it is conceivable that challenges in which there is a ranking but also points, the killer and the Achiver are assigned, with both types of players pursue different game objectives.

Conceivable, constructed gamification scenario:

The trainee has synchronized the corresponding app with our bolt and there already created his profile and determined which gamification features he wants to use. In our example, the trainee joined the breastplate weight limb, which is already attended by 5 other gymnastic members. The challenge is 7 days. The operator has deposited for this Challenge either 100 points or a mineral drink for the winner.

Bolt, pin, measuring device and the like, as well as easily recognizable from the context, represent all the names of the device according to the invention.

The trainee now logs on to our bolt. In the next step, he sets the device (in this case the sitting chest press) according to his anatomy and fixes with our bolt the desired weight and begins the first set of his exercise. After 12 repetitions and the fixed weight of 60 kg, he finishes the first set and drops the weight. At the bolt he now sees how many repetitions he has done with what weight. By "scrolling" on the next page of the display, he now recognizes that 2 members have taken more weight in front of him and he is currently in 3rd place. Bolstered by ambition, he raises the weight to 90 kg in the next set and completes 3 reps, causing him to slip into second place. At the end of the 7-day challange, he will be informed by push notification about the final result. If winning, he can now choose whether he wants the points or the mineral drink. Due to the ambition of the trainee, he deviated in the example mentioned from hypertrophy training (muscle building) and has completed a maximum power set. Maximum strength training increases strength values over time more than hypertrophy training. As a result, over time, the exerciser can apply the gained power through the maximum strength training for hypertrophy training as well. This means that he will do 12 repetitions with more weight than before. If the trainee has defined hypertrophy as a training goal, he has increased his maximum strength by gamification, which means he can achieve better results in the hypertrophy training by the force gained. However, this is of course a long-term result, which can not be achieved self-explanatory after participating in the gamification.

Our bolt (the device according to the invention) offers the studio operator added value at various levels ( 5 ).

• - Monitoring (Wer trainiert, wann, wo, was) (Welche Geräte sind in Gebrauch?) (Kontrolle des Geräteparks, Verschleiß, Nutzung, Umgang mit dem Gerät)
• - Kundenbindung (durch die Erweiterung des Diensdeistungsspektrums, hat der Studiobetreiber mehr Kontrolle darüber, Mitglieder gezielter emotional am Studio zu binden)
• - Kundenneugewinnung (lead generation) (durch die Gamification hat der Studiobesitzer die Möglichkeit den Bekanntheitsgrad des Studios gezielt zu erhöhen ohne teure Ads über Facebook, Google und co. erwerben zu müssen.)

This includes:

• - monitoring (who trains, when, where, what) (which devices are in use?) (Control of the equipment, wear, use, handling of the device)
• - Customer loyalty (by expanding the range of services offered, the studio operator has more control over tying members to the studio in a more focused way)
• - Lead generation (through gamification, the studio owner has the opportunity to increase awareness of the studio without having to purchase expensive ads via Facebook, Google and co.)

In order to increase these added values even further, the points mentioned in the "User Features" offer themselves as internal studio currency (tokens). Thus, the studio owner can actively increase the motivation by awarding bonus points and send personalized texts on the smartphone and in the future on the display of the bolt.

Example:

The exerciser performs 4 repetitions on the shoulder machine. With these 4 repetitions, the maximum strength is trained but less the muscle build-up. However, if the muscle is the target of the exerciser, the display% of 1RM can see that there are still about 4 repetitions missing to reach the goal. Now you can see on the display "4 more repetitions, then you get 200 bonus points" or "4 more reps, then you can pick up a free mineral drink" etc.

Similar examples can also be used for sharing on social media.

"Share your results on Facebook and get 30% on your protein shake" etc.

As can be seen, our bolt allows the studio operator precise control of the marketing activities to achieve the respective marketing goal.

Furthermore, we allow the studio operator the opportunity to attach an external screen, for example, above the counter in order to publish current rankings, winners, winners of the day, etc. In terms of data protection, we refer to the paragraph above.

Output Device:

• - the bolt's display: exercise duration, current exercise, set, reps, weight, calories burned (total / current exercise), training recommendations, learning content, progress bars, analysis, and short animations that show in comic style how to complete each exercise is.
• - the smartphone (like bolts, additional challenges and more information about friends and training partners)
• - the display above the counter (best of the day, current challenges, daily calorie consumption of the studio, etc.) 3
• - Display via the cloud in the studio operator app (like smartphone)
• - Desktop PC
• - Tablet

Currently, the output of personalized texts and the more detailed gamification mapping is limited to the smartphone, the tablet and the desktop PC. The playout of rankings, points, challenges, etc. on the display of the bolt will follow.

Furthermore, we provide the provision of interfaces for third-party providers. This allows us to integrate new features faster and more agile for testing, before we spend resources to implement new features in our own solution. In addition, the interfaces offer the opportunity to increase the awareness and thus the range of our bolt.

Sponsorship / Cooperation

Sponsoring, cooperations and advertising partnerships serve the purpose of further monetization in addition to the end customer business. It is conceivable that these other forms of monetization not only increase our profitability but also that of the gym. Thus, the customer can also earn additional income with our bolt in addition to the savings through better customer loyalty and customer acquisition.

So it is conceivable that banner ads are displayed on the bolt display. These ads are paid for by the advertiser. In addition, personalized advertising is also possible for registered users if the trainee has consented to the use of personal data in the terms and conditions. In this case, the advertising is recorded on the basis of the interests that are stored in the social media area of the user.

The same scheme is conceivable in the award of coupons. Here, a fixed contingent of coupons deposited in the studio, which can be redeemed for points (tokens). Only when redeeming the coupon, a commission is due to the studio operator.

This converts redeemed points (tokens) that are considered internal studio currency into real money.

Cooperation with health insurances becomes interesting when they realize that valid Data can be transmitted. It is currently common in practice that certain health insurance companies cooperate with certain fitness studios. Here, the health insurance pays part of the membership fee of the trainee. Disadvantage here is however that on the part of the health insurance companies there is no possibility to increase the frequency of the completed training, let alone receive valid data. In this case, the bolt provides a tool for controlling and controlling the training behavior. Here, in a cooperation between gym and health insurance our bolt is used as a control between. The health insurance company can thus specifically control the subsidization of the membership fee and adjust it to the appropriate training frequency. As a result, the health insurance saves money and has an active influence on the health-oriented behavior of their health insurance members. This would also be possible anonymously via corresponding coupons of the KK.

In the field of e-learning, cooperations with academies are conceivable, among others, which offer the acquisition of a coaching license etc. via distance learning. Nowadays it is already possible to complete his coaching license online, which is certainly critical given the lack of supervision and lack of practical experience. In such cases, our bolt provides more control over the learning success as well as additional practical experience. For the cooperating academies, this form of cooperation offers a new opportunity for customer acquisition. Monitaire participates the gym by pro rata commissions.

As can be seen in the examples mentioned, there are various possibilities for further monetization. Through proportional commissions, both the studio operators and our company can increase their economic viability.

In general, of course, it should be noted that the data, in particular the personal data is not used without authorization or even passed on. From the training results very sensitive data can be obtained, which go far beyond normal registration data.

Example procedure and use of the device according to the invention.

The user (mobile version) or an employee of the studio (stationary variant) configures the measuring device once with the aid of the display 3 so that he has set the meter for training optimal. This is therefore only required when first commissioning a measuring device on a new training device. The bolt (pin) is pushed into the hole of the lowest weight plate. Now the distance to the ground is measured and recorded. The display shows the distance to the ground. For safety, this should be checked with a manual measurement. If the information is correct, this is confirmed to the device and the total weight of the weight block to be lifted in this setting is entered. Distance and weight plate are now interlocked so that the distance also describes the weight plate and from this the total weight to be determined. Now the distance of each weight plate is determined with the help of the measuring device and as previously confirmed with the appropriate weight indication. As an alternative to manual configuration, records of the fitness studio operator (stationary version) or of a training partner (mobile version) can be used, if available. The bolt now recognizes at the height, ie the distance to the ground the respective weight plate and thus the total weight.

After that, the user determines his training mode. This can for example be anonymous or personal. In personal mode, he logs into the measuring system. Multifunction training devices are awarded separately in the configuration. Multifunctional training devices are devices on which several different exercises can be completed. Here the trainee can select the exercise to be carried out in advance after each log-in procedure.

• - Jemand trainiert allein an einem Gerät und loggt sich dabei nicht ein - Er trainiert nun automatisch im anonymisierten Modus. Dieser wird durch eine rot-blinkende Statuszeile mit dem Text ‚anonym‘ gekennzeichnet. Möchte er seinen Trainingsverlauf an weiteren Geräten mitverfolgen, so muss er eine Chiffre eingeben.
• - Jemand trainiert allein an einem Gerät und er loggt sich ein - Das korrekte Einloggen wird durch eine grüne Statuszeile mit dem Text ‚eingeloggt‘ signalisiert. Nach Abschluß des Trainings muss er sich ausloggen. Alternativ wird er auch nach 20 Minuten automatisch ausgeloggt, wenn er den Empfangsbereich des Scatternets verlässt oder wenn sich wieder jemand einloggt.
• - Mehrere trainieren an einem Gerät und alle loggen sich immer korrekt ein - Ein Ausloggen ist dann nicht erforderlich. Beim erneuten Einloggen an einem Gerät, an dem wir die Übung nicht beendet haben, wird über das Display gefragt, ob mal eine neue Übung beginnen oder die alte fortsetzen möchte.

• - Mehrere trainieren an einem Gerät und mind. einer loggt sich dabei nicht ein - Wenn eine Person anonymisiert trainieren möchte (oder einfach das Einloggen vergessen hat), muss sich der Vorgänger ausloggen, damit die Übung nicht ihm zugeordnet wird. Ein ausgeloggter Zugang wird über eine schwarze Statuszeile mit dem Text ‚Bereit‘ signalisiert. Beginnt in diesem Zustand eine Übung (also ohne vorheriges Einloggen) so ändert sich die Statuszeile in ‚rot-blinkend‘ mit dem Text ‚anonym‘.

The logon and logout process can proceed as follows:

• - Someone is training alone on a device and does not log in - He is now training automatically in anonymous mode. This is indicated by a red flashing status line with the text 'anonymous'. If he wants to follow his training course on other devices, he must enter a cipher.
• - Someone is training alone on a device and he logs in - The correct login is signaled by a green status line with the text 'logged in'. After completing the training, he must log out. Alternatively, it will be automatically logged out after 20 minutes if it leaves the reception area of the scatternet or if somebody logs in again.
• - Several train at a device and all always log in correctly - a logout is then not required. When you log in again on a device where we did not finish the exercise, the display asks if you want to start a new exercise or continue with the old one.

• - Several train at a device and at least one does not log in - If a person wants to train anonymously (or simply forgot to log in), the predecessor must log out so that the exercise is not assigned to him. A logged-out access is signaled via a black status line with the text 'Ready'. If an exercise starts in this state (ie without prior login), the status line changes to 'red-blinking' with the text 'anonymous'.

When the weights are at rest, the display will show 'End sentence' and 'End exercise'. The operation is optional.

1 shows the schematic structure of the device according to the invention for measuring training performance in weight-based fitness equipment.

In this figure is clearly the device according to the invention with the pin-shaped holding means 1 to see. On the pin (bolt) is the rest of the device, namely the functioning on optical basis measuring module 2 and the touch display 3 , The measuring module 2 is shown in this figure as a laser measuring device, which is here directed down to the ground. It will in this case the distance measurement module 2 measured to the ground or to a ground-level point located on the device. The touch display 3 So a combination of a display and a touch screen is also clearly visible. the display 3 is directed upwards and thus designed user-friendly For certain exercises, the display 3 even seen during the exercise and the data are read. The pencil 1 has a diameter of 8-10 mm in this illustration. These are diameters, which also have the most commercial weight bolts. Weight bolt and inventive device can thus be easily replaced and the function of the device is given immediately. There is no mounting necessary. The head of the device, which is the touch display 3 includes a width of 60 - 80 mm. In this case, the head has an oval teardrop shape. The display size is selected in such a way that the inputs and the reading are easily possible. Since the geometry of the exercise equipment can diverge slightly, here is between the pin-shaped bolt 1 and the head a distancer 4 , So a way to extend the device attached. This extension can be configured for example as a telescopic arm. Thus, the device can also be used in a variety of exercise equipment, regardless of whether the device head due to the geometry of the device can not be brought close enough to the weight plates. The device or the pen 1 is simply extended and the distance to the bulky head is bigger. The the device according to the invention from the side (top) shows the touch display 3 alone (bottom left) and from above (bottom right), but without the pen 1 to show completely. Furthermore, the retaining means 1 , preferably a pin or rod having a diameter of 8-10 mm, should this holding means 1 not sufficient to hold the weight to be moved, so can a reinforcing sleeve on the holding means 1 be striped.

In a very advantageous embodiment, the device according to the invention is attached to the weight-bearing original pin or the pin located on the device.

As a laser measuring device 2 For example, a ST VL53L0X laser time-of-flight distance sensor can be used. It has a fully integrated miniature module and a 940 nm surface emitter (laser). Its dimensions are 4.4 x 2.4 x 1.0mm. It works in the measuring range of 20 mm - 2000 mm and is independent of the reflectance of the Target surface. Its operation is possible in the IR environment. It has advanced optical crosstalk compensation. Its field of view (FOV) is 25 degrees, with a resolution of 1 mm and an accuracy of +/- 3% and a maximum measurement frequency at 50 Hz.

The module can contain both energy and data storage. The module can either be connected without contact with the bolt for energy and data transmission or by means of a long-lasting plug connection, for example a chip card contacting unit according to ISO 7816 ID. 1 , Alternative data transmission via RFID would also be conceivable. For contactless execution, the industry standard Qi should be mentioned. Advantage of this standard Qi is a wear-free connector.

By using RFID tags on the fitness equipment, the stationary bolts can also be more easily configured via the studio or user database. After a scan of the identifier by means of the measuring device, the fitness device is shown on the display and only has to be confirmed.

Furthermore, the exemplary receiving and transmitting and other processing units, so a whole network can be seen.

Exemplary training course

the display 3 displays the application immediately. The trainee completes the now prescribed exercises, which he also on the display 3 gets displayed. The displayed data are not retrieved today as usual according to his personal training plan, but today is a day of competition, in which a circle of prescribed exercises must be completed. His personal training plan, the trainee but also on the base server 6 filed, which manages the data there for him. The base server 6 can be on site, for example next to the counter monitor 8th but it can also be a server on the Internet, a cloud server that manages the data. This server is over the router / gateway 9 if the member card activates a training device or the measuring device. This gateway serves as an interface to the Internet. The measuring devices can also exchange the training data with one another without the aid of the scatternet. If the data is to be shared with third parties or stored in the cloud, this module is required. When using a Serve, a database is searched for specifications for the upcoming training and if they are present, they are transmitted to the measuring device and on the display 3 (the passage may be removed after adding the gamification). Today, however, the task list is displayed. The data created by trainees after completion of the exercises can be transmitted to mobile and non-mobile receiving units, such. For example, mobile phones, tablets, notebooks and of course computers and their counterparts on the Internet. The data prepared by a suitable software are now processed graphically and on the counter monitor 8th shown there are the interested sports fans gathered to experience the interesting events live. On request, the data and results can also be displayed in ranked form and sent by e-mail or forwarded to other social network groups.
