DE102019003794A1 - Mobile strength training device for people to train all major muscle groups - Google Patents

Abstract

Available training devices, which allow training of all main muscle groups with maximum arbitrary strength, are very difficult to transport and require considerable financial, time and spatial resources for their use. The invention should be easily transportable and enable a training of all main muscle groups with maximum arbitrary force development with little space requirement. A trunk loop, several connecting loops and two foot loops made of tear-resistant material, the arrangement of which is variable, enable a power transmission from the trunk to the extremities or between the extremities. The exercising person exerts force with one part of the body and develops resistance to that force with another part of the body. Numerous strengthening exercises of conventional strength training can be performed, for example, the trunk loop (1) can be connected on each side with a loop chain (4) made of connecting loops (2), at the other end of which a foot loop (3) is connected. The foot and torso loops can be connected directly to the loop chain (2, 3) or indirectly via connecting loops of different sizes and designs (18). Training of all major muscle groups with maximum voluntary strength.

Description

Numerous positive physical effects of resistance training have been proven for adults into old age. These include increasing muscular strength and endurance, improving blood pressure, reducing insulin resistance and (especially intra-abdominal) body fat, increasing basal metabolic rate, improving cognitive abilities and having a positive effect on mood, anxiety and depression [1, 2, 3 ]. The Federal Center for Health Education has therefore recommended since 2016, in addition to regular endurance-oriented exercise, muscle-strengthening physical activities on at least two days a week [4]. The American College of Sports Medicine, the world's leading sports medicine association, substantiates this recommendation by stating that adults should do resistance training two to three times a week for each major muscle group [3].

State of the art

Mechanical strength training of all major muscle groups requires different strengthening exercises to be carried out. To make this possible, numerous stationary or mobile training devices have been developed.

1. 1. Konventionelle Kraftgeräte ermöglichen, entsprechend ihrer gegen den Widerstand des Gerätes vorgegebenen Bewegungsrichtung, dynamische oder statische Widerstandsreize für einzelne aber nicht alle (Haupt-)Muskelgruppen. Konventionellen Kraftgerätestationen ermöglichen häufig ein dynamisches und statisches Krafttraining aller Hauptmuskelgruppen. Aufgrund ihrer Größe sind diese Kraftgeräte(-stationen) für einen stationären Einsatz konzipiert. Für einen Transport, der einen Transporter oder einen LKW erfordert, müssen diese Geräte in der Regel demontiert und auf Paletten verladen werden. Da der Trainingswiderstand in der Regel über Gewichte generiert wird, die gegen die Schwerkraft bewegt werden, haben solle Kraftgeräte ein erhebliches Eigengewicht [5, 6, 7].
2. 2. Kurz- und Langhanteln ermöglichen ein dynamisches oder statisches Krafttraining aller Hauptmuskelgruppen. Für ein Training submaximaler bis maximaler Intensität bestimmter Muskelgruppen, wie etwa der Kniegelenkstrecker oder der Brustmuskulatur, sind Gewichte erforderlich, die für bestimmte Übungen 100 kg leicht übersteigen können. Zudem erfordern bestimmte Übungen, wie Kniebeugen oder Bankdrücken, bei höheren Lasten Haltevorrichtungen, die nur als Sperrgut transportabel sind. Ein Gefährdungsmoment des Freihanteltrainings ist, dass der Trainierende bei bestimmten Übungen wie Langhantelkniebeugen oder Bankdrücken Zwangspositionen einnimmt, aus denen er sich aus eigener Kraft nicht mehr befreien kann, wenn die Muskulatur die wirkende Gewichtskraft nicht mehr überwinden kann [8, 9, 10].
3. 3. Seilzugstationen ermöglichen ein dynamisches oder statisches Krafttraining. Wenn keine zusätzlichen Widerlager genutzt werden, findet bei diesen Geräten eine Kraftüberleitung von den beanspruchten Extremitäten des Trainierenden über dessen Rumpf und Beine in den Boden statt. Daher erfordert und trainiert dieses Trainingsprinzip den Einsatz der Rumpfmuskulatur. Während die Muskulatur des Oberkörpers, abhängig von der durchgeführten Übung und dem Gewichtswiderstand, submaximal belastet werden kann, ist für große Muskelgruppen der unteren Extremität keine maximale Belastung erzielbar. Durch ihr Volumen und ihr Gewicht sind Seilzugstationen nur mittels Transporter oder LKW transportabel [11].
4. 4. Isometrische Trainingsstationen ermöglichen einen Kraftreiz aller Hauptmuskelgruppen bis zur maximalen willkürlichen Kraft. Aufgrund ihrer Größe sind sie nur mit größerem Aufwand zu transportieren [12, 13, 14, 15, 16].
5. 5. Ein prinzipiell, wenn auch mit erhöhtem Aufwand, transportables isometrisches Krafttrainingsgerät für sämtliche Hauptmuskelgruppen, dass aus handelsüblichen Materialien aus dem Baumarkt selbst zusammengebaut werden kann, hat den Nachteil, dass für jede Kräftigungsübung eine neue Einstellung vorgenommen werden muss, indem Karabiner in entsprechende Kettenglieder eingehakt werden müssen [14].
6. 6. Endisometrische, transportable Krafttrainingsgeräte mit Federwiderstand ermöglichen eine maximale willkürliche Ausbelastung der meisten Muskeln der oberen Extremität. Submaximale und maximale Trainingsreize für die untere Extremität sind aufgrund der stabförmigen Konstruktion und nicht ausreichender Kraftkoppelungselemente für die Füße nicht möglich [17, 18].
7. 7. Elastische Widerstandsbänder sind sehr gut transportabel. Sie ermöglichen primär ein dynamisches Kräftigungstraining. Während die Muskulatur der oberen Extremität bis in den submaximalen Bereich trainiert werden kann, lassen sind solche Trainingsreize für die stärkere untere Extremität nicht erzielen. Ein Training im Bereich der maximalen willkürlichen Kraft ist für Fortgeschrittene mit dieser Geräteklasse nicht durchführbar. Zudem warnen wiederholte Meldungen von belastungsbedingten Durchrissen dieser Bänder. Daher kann im höheren Belastungsbereich eine erhöhte Verletzungsgefahr bestehen [19, 20].
8. 8. Schlingentrainer ermöglichen ein effektives, dynamisches Ganzkörpertraining mit dem eigenen Körpergewicht. Da die Kraftübertragung in der Regel von einem Extremitätenpaar über den Rumpf des Trainierenden auf das andere Extremitätenpaar verläuft, muss der Trainierende seinen Rumpf während dieser Kräftigungs- und Kraftausdauerübungen selbst stabilisieren. Hieraus resultiert eine häufig gewünschte Kräftigung der wirbelsäulenstabilisierenden Muskulatur. Die Kraftüberleitung über die beweglichen Schlingen verstärkt diesen Effekt und trainiert gleichzeitig die Koordination. Ein Training der maximalen willkürlichen Kraft, vor allem der großen Muskelgruppen der unteren Extremität, ist mit diesen Trainingsgeräten nicht möglich. Schlingentrainer sind sehr gut transportabel. Beim Training ist der Platzbedarf durch die Schlingenkonstruktion etwas erhöht. Zudem wird ein Widerlager zur Befestigung der Schlinge über dem Trainingsbereich benötigt [21].

These training devices differ in the quality of the training stimulus, in the usability by certain user groups and in the resources required for their use. In the following, the properties of individual groups of training equipment that are currently on the market are outlined.

1. 1. Conventional strength machines enable dynamic or static resistance stimuli for individual but not all (main) muscle groups, depending on the direction of movement given against the resistance of the machine. Conventional strength training stations often allow dynamic and static strength training of all major muscle groups. Due to their size, these strength machines (stations) are designed for stationary use. For transport that requires a transporter or a truck, these devices usually have to be dismantled and loaded onto pallets. Since the training resistance is usually generated by weights that are moved against gravity, strength machines should have a considerable dead weight [5, 6, 7].
2. 2. Dumbbells and barbells enable dynamic or static strength training of all major muscle groups. For a training of submaximal to maximum intensity of certain muscle groups, such as the knee extensor muscles or the chest muscles, weights are required that can easily exceed 100 kg for certain exercises. In addition, certain exercises, such as squats or bench presses, require holding devices for higher loads that can only be transported as bulky goods. A dangerous element of free dumbbell training is that the trainee assumes compulsory positions during certain exercises such as barbell squats or bench presses, from which he can no longer free himself if the muscles can no longer overcome the weight force [8, 9, 10].
3. 3. Cable pull stations enable dynamic or static strength training. If no additional abutments are used, these devices transfer forces from the exercised extremities to the floor via their torso and legs. Therefore, this training principle requires and trains the use of the core muscles. While the muscles of the upper body, depending on the exercise performed and the weight resistance, can be subjected to sub-maximum loads, no maximum load can be achieved for large muscle groups of the lower extremities. Due to their volume and weight, rope hoist stations can only be transported by transporter or truck [11].
4. 4. Isometric training stations allow all main muscle groups to be stimulated up to their maximum voluntary strength. Due to their size, they can only be transported with greater effort [12, 13, 14, 15, 16].
5. 5. A transportable isometric strength training device for all major muscle groups, which can be assembled from commercially available materials from the hardware store, has the disadvantage that a new setting must be made for each strengthening exercise by inserting carabiners into corresponding chain links must be hooked [14].
6. 6. Endisometric, portable, resilient strength training equipment allows for maximum arbitrary strain on most muscles of the upper extremity. Submaximal and maximal training stimuli for the lower extremities are not possible due to the rod-shaped construction and insufficient force coupling elements for the feet [17, 18].
7. 7. Elastic resistance bands are very easy to transport. They primarily enable dynamic strengthening training. While the muscles of the upper extremity can be trained down to the submaximal range, such training stimuli cannot be achieved for the stronger lower extremity. Training in the area of maximum voluntary force is not feasible for advanced users with this class of equipment. In addition, repeated reports warn of tears in these ligaments due to stress. Therefore, there may be an increased risk of injury in the higher stress range [19, 20].
8. 8. Sling trainers enable an effective, dynamic full-body training with your own body weight. Since the power transmission usually runs from one pair of extremities over the trunk of the person exercising to the other pair of extremities, the person exercising has to stabilize his / her trunk during these strengthening and endurance exercises. This results in a frequently desired strengthening of the muscles that stabilize the spine. The transfer of force via the movable slings reinforces this effect and trains coordination at the same time. A training of maximum voluntary strength, especially of the large muscle groups of the lower extremities, is not possible with these training devices. Sling trainers are very easy to transport. During training, the space requirement is slightly increased due to the loop construction. An abutment is also required to attach the sling over the training area [21].

A general comparison of different groups of training devices is neither useful nor expedient due to their different properties and areas of application. Table 1 shows that each group of exercise equipment has specific advantages and disadvantages.

The ordinate lists the various types of strength training equipment, including the mobile strength training equipment for which a patent is pending. Advantageous properties for the usability of a strength training device are named on the abscissa, arranged according to the quality of the training stimulus, possible user group and the resources required for training.

The intersections show in school grades (from “1”: very good to “6”: unsatisfactory) how well the individual strength training equipment groups fulfill the respective properties.

problem

The invention specified in claim 1 is based on the problem that the currently available, easily transportable training devices do not allow effective training, especially of the lower extremities, in the range of maximum voluntary force and therefore not all main muscle groups can experience an effective force stimulus with these devices. Those strength training devices that allow strengthening training of the lower extremities in the range of maximum voluntary strength are (very) limitedly portable and use numerous resources, including a lot of space. Therefore, the trainee usually has to go to a training facility if he wants to use the advantages of strengthening the legs in the area of maximum voluntary strength.

solution

The invention specified in claim 1 solves this problem and enables strength training of all main muscle groups with the maximum arbitrary strength with little space requirement with an easily transportable training device.

This is made possible by the fact that the aforementioned strength training device (drawings 1 and 2) uses loops made of tear-resistant material to transmit force from the trunk to the extremities or between the extremities. In this way, the exercising person will arbitrarily apply force with a certain part of the body in a certain direction and at the same time develop resistance to that force with another part of the body.

The torso sling serves as the starting point for these compressive and tensile forces ( 1 ) (Preferably on the shoulders, back or pelvis), the connecting loops ( 2 ) (Grip elements for the hands) and two foot loops ( 3 ) (Starting point preferably for the feet). The arrangement of the trunk loop ( 1 ), the connecting loops ( 2 ) and the ankle loop ( 3 ) is in principle variable.

In the basic design of the strength training device mentioned in claim 1, the torso sling ( 1 ) via a connecting loop ( 18th ) on each side with a loop chain ( 4th ) connected. The other ends of the sling chains are each secured with a foot sling ( 3 ) connected.

The torso sling ( 1 ), the connecting loops ( 2 ) and the ankle loops ( 3 ) can be made of tear-resistant fabric or fabric or another tear-resistant material, for example. The connection between the material ends of the trunk loop ( 1 ), the ankle loops ( 2 ) and the connecting loops ( 3 ), which create a loop shape, can be created, for example, by sewing together with tear-resistant thread. The torso sling ( 1 ) and the ankle loops ( 3 ) can be used directly with the connecting loops ( 2 ) or indirectly via connecting loops of different sizes and designs ( 18th , 22nd ), which in turn are directly connected to the torso and foot loops (drawings 1, 2, 27 and 28).

The torso sling ( 1 ) can contain a padding to distribute the pressure generated by the exertion of force more evenly over the contact surface. The connecting loops and the foot loops ( 3 ) can be designed partially or completely from a solid or only slightly flexible, tear-resistant material.

With the training device mentioned under claim 1, numerous strength training exercises can be performed with dumbbells or with conventional strength equipment. Which parts of the body which element of the invention is used for power transmission are listed in Table 2 for some strengthening exercises.

Further embodiment of the invention

An essential element of the strength training device mentioned in claim 1 is the loop chain mentioned in claim 2 ( 4th ) from connecting loops ( 2 ) (Drawings 1, 2, 3, 4, 5 and 6). The loop chain mentioned under claim 2 ( 4th ) serves as a power transmission element in all strengthening exercises.

Due to their construction made of tear-resistant material, each of the connecting loops connected as a chain serves either as a passive force transmitter up to the point where the force is applied ( 5 ) or as a handle ( 6th ), which the exercising person can use to exert force on the training system (Figure 5).

Connecting loops that are outside the power transmission remain unloaded at this moment (7).

If a connecting loop serves as a passive power transmitter, its long sides run (approximately) parallel (8) due to the tensile force and it may be stretched, depending on the material properties (drawing 6).

If a connecting loop is used as a handle ( 6th ) is used, it forms approximately an isosceles triangle under tensile or compressive load ( 9 ), at the base of which the palm of the person exercising grips (drawings 5 and 6).

According to the information under patent claim 1, the connecting loops can also be designed triangularly from a rigid or only slightly flexible, tear-resistant material (10). Then a connection chain results ( 11 ) made of triangular elements (drawing 7).

The loop chain mentioned under claim 2 enables the grip position to be changed from one connecting loop to another at any time without any delay. The strength training device does not have to be converted for this. As a result, the load angle can be changed immediately with every strengthening exercise or you can switch from one strengthening exercise to another.

In addition, the connecting loops or triangular connecting elements are the attachment zone for the advantageous configurations of the training device mentioned in claims 3, 4, 5, 6, 7, 8 and 9.

It is conceivable that a loop chain mentioned in claim 2 will also be used in the future in other strength training or traction devices if a high load capacity together with a low weight and the possibility of a simple and quick adjustment of the grip position are required.

Another advantageous embodiment of the invention is the variation mentioned in claim 3 of the loop chain mentioned in claim 2 (drawings 8 and 9). With removable connecting elements ( 12th ) according to claim 3 in the course of the connecting chains ( 19th ) between trunk loop ( 1 , 18th ) and foot slings ( 2 ) the connecting chains ( 19th ) so that independent, mutually usable, functional units of the strength training device mentioned under claim 1 arise: the torso sling ( 1 ) with (possibly shorter) connecting chains ( 19th , Drawing 10), the foot loops ( 3 ) each with a (possibly shorter) connecting chain ( 19th , Drawing 11) or (possibly shortened) connecting chains ( 19th ) without trunk and foot sling (drawing 12).

The removable connecting elements can be inserted between two connecting loops at any point in the connecting chain.

The removable connecting elements can be designed, for example, in the form of a rapid link or carabiner and differ in size.

If the training person only wants to perform some of the possible strength training exercises in a certain period of time, the further development according to claim 3 enables the training device to be adapted to this training requirement and thus even easier transport and even simpler use.

The torso sling ( 1 ) with a shorter connecting chain ( 19th ) on each side (drawing 10) enables the training exercises chest press, dips, triceps presses, seated shoulder presses, seated lateral raises, seated front raises or seated biceps curl (see Table 2). The ankle loops ( 3 ) each with a shorter connecting chain ( 19th , Drawing 11) can be used for the training exercises deadlift, bent row, front squat and biceps curl while standing (see table 2).

If in the course of the connection chains ( 19th ) between trunk loop ( 1 ) and foot slings ( 2 ) two or more of the removable connecting elements mentioned under claim 3 ( 12th ), the connecting chain can be opened by removing connecting loops ( 2 ) and individual removable connecting elements ( 12th ), shorten. Unused sections of the connection chain ( 12th ) can be removed reversibly. In this way, the strength training device mentioned under claim 1 can be adapted even better to the individual training needs, which among other things depend on the length of the person (drawings 13 and 14).

In addition, the removable connecting elements ( 12th ) according to claim 3 either in addition to or instead of connecting loops ( 2 ) rigid or stretchable connecting elements according to claims 6 and 7 or force measuring elements according to claim 8 in the connecting chain ( 12th ) insert or attach a variably attachable trunk loop according to claim 9 to the connecting chain.

An advantageous embodiment of the invention is mentioned in claim 4. By doubling the material volume in the grip area of a connecting loop ( 2 ) a grip thickening ( 13 ) (drawings 15 and 16). The connection between the material ends in the area of the handle thickening ( 13 ) can be created, for example, by sewing together with tear-resistant yarn.

In the alternative design of the connecting loops as triangular connecting elements made of a rigid or only slightly flexible, tear-resistant material, so much material is used on at least one side of this triangle that a diameter is created that can be ergonomically enclosed with the palm of the hand. In order to use all sides of the triangular connecting element so that people with different hand sizes can train optimally, each of the three sides can be designed with a different grip volume.

The larger handle volume and the higher stability in the area of the handle doubling ( 13 ) have an advantageous effect on the power transmission, because at this point gripping is more comfortable for the exercising person due to better pressure distribution over the palm or fingers.

With training intensities in the maximum arbitrary force range, high forces and thus high pressures arise at the force transmission points. While the feet are usually padded with footwear, these pressures can cause pain in the hands that limit the intensity. The thickened handle ( 13 ) during pushing, pulling and lifting exercises, the pressure load is more evenly distributed over the palm or fingers of the person exercising. As a result, the aforementioned strength training device can be used effectively at any time without additional equipment, such as pads or training gloves.

In pulling exercises in the area of maximum voluntary strength, the developable grip strength can be performance-limiting. Here, the larger grip volume of the grip thickening according to patent claim 4 (13) enables an increase in the developable grip strength and thus higher training stimuli and effects.

Due to the long overlap section, the connection of the loop ends of a connecting loop can also be made very stable, whereby the tear resistance is reliably guaranteed even with high forces.

Another advantageous embodiment of the invention is mentioned in claim 5. An additional ergonomic handle ( 14th ) on the connecting loops ( 2 ), compared to the advantageous embodiment according to claim 4, the pressure load for the palm and fingers can be distributed even better and thus reduced even more (drawings 17 and 18). This handle ( 14th ) can be cylindrical or slightly convex or, as a variant, in the form of a triangular, slightly convex cylinder with rounded corners.

Alternatively, several handles of different shapes, for example for pushing and pulling exercises, can be attached in or on the connecting loops.

In the alternative design of the connecting loops as triangular connecting elements according to patent claim 2, at least one side of this triangle contains an ergonomic handle as mentioned above or is designed in this shape. Because of the triangular shape of this alternative connecting element, a handle different in size and shape can be attached or designed on each side.

Since the mentioned strength training device should be ready for use at any time and without preparation by the person exercising, an optimal pressure distribution by means of one of these grip variants, through which a significantly better pressure distribution is created for the palm of the hand, is advantageous for all pressure exercises.

In addition, the grip strength that can be developed without additional equipment is increased even more. Due to the design according to claim 5, the strength training device mentioned under claim 1 can be used to train even more comfortably without additional equipment, or even higher force intensities and thus training stimuli can be achieved by the person exercising.

In addition, the handle design mentioned ( 14th ) Training beginners the places provided for power transmission and enables additional, for example colored, markings for different training positions.

Another advantageous embodiment of the invention is specified in claim 6. The insertable, rigid connecting elements mentioned in claim 6 ( 15th ), for example in the form of a carabiner or a rapid link, are used in the course of the loop or connecting chain ( 19th ) on two connecting loops ( 2 ) or connecting elements ( 10 , 15th ) reversibly attached. They allow the distance between the trunk ( 1 ) and the ankle loops ( 3 ) to adapt to the size of the exercising person without connecting loops ( 2 ) from the loop chain ( 19th ) must be removed (drawings 19 and 20).

This length adjustment allows people with different body and limb lengths to train effectively with the same strength training device. An individual production of the strength training device described according to the body dimensions of each individual exercising is no longer necessary due to the design according to claim 6. Regardless of this, it can still be useful to manufacture the training device mentioned under claim 1 with trunk, connecting and foot loops of different sizes so that not only different body and limb lengths of the exercising person, but also different hand and foot sizes are taken into account.

Due to the length adjustment described by insertable, rigid connecting elements ( 15th ) According to patent claim 6, the trainees can do exercises that involve power transmission from the torso sling ( 1 ) on the ankle loops ( 3 ), also train with different joint angles and thus achieve different loads and training effects.

The use of insertable, rigid fasteners ( 15th ) according to claim 6, which are shorter than individual connecting loops ( 2 ) according to claim 1, also enables intermediate distances to be established for power transmission. As a result, the position of the joints can be adjusted even closer to the training needs and goals of the person exercising with each strengthening exercise.

Another advantageous embodiment of the invention is specified in claim 7. The insertable, stretchable connecting elements ( 16 ) are in the course of the loop or connecting chain ( 4th , 11 , 19th ) on two connecting loops ( 2 ) or connecting elements ( 10 , 15th ) reversibly attached ( Drawings 21 + 22). The insertable, stretchable connecting elements ( 16 ) can be designed, for example, on the basis of a spring mechanism that can be stretched or compressed or on the basis of a rubber that can be stretched or compressed. The insertable, expandable connecting elements ( 16 ) be surrounded, for example, by a housing, a capsule or a grid, which prevents clothing or skin of the exercising person from getting caught in the stretchable connecting element.

The material used to manufacture the strength training device mentioned in claim 1 has a certain elasticity. With increasing tensile force, the material is stretched before it would tear if the maximum load capacity was exceeded. Due to the nature of the material and the equipment, this maximum load capacity is far above the forces that even a high-performance athlete can develop. The exercising person therefore first exerts a (concentric) dynamic force over a short distance, before they statically develop their maximum force when their applied force corresponds to the restoring force of the material.

The further development according to patent claim 7 enables dynamic strength training with the above-mentioned invention over a distance that is caused by the connecting loops ( 17th ) or the maximum stretchability of the insertable, stretchable connecting element ( 16 ) is set. Due to the selected starting position of the training exercise and the distance of the bridged connecting loops ( 17th ) the angle of movement for dynamic strength training can be specified or limited with the invention mentioned under claim 1.

1. 1. Der durch das dehnbare Verbindungselement (16) nach Patentanspruch 7 überbrückte Abschnitt der Schlingen- bzw. Verbindungskette (17) ist so groß, dass die Endposition der Trainingsübung erreicht wird, bevor das einfügbare, dehnbare Verbindungselement (16) auf die Länge der primär übergangenen Verbindungsschlingen (17) gedehnt oder seine maximale Dehnbarkeit erreicht wird. In diesem Fall überwindet die trainierende Person über diesen Bewegungsbereich den Widerstand des einfügbaren, dehnbaren Verbindungselementes (Zeichnung 22). Gegenüber einem dynamischen Training mit konventionellen Krafttrainingsgeräte, die über den kompletten Bewegungsspielraum den gleichen, gewichtsabhängigen Trainingswiderstand entwickeln, erhöht sich bei der Dehnung einer Feder oder eines Gummis der entstehende Widerstand mit zunehmender Materialdehnung. Dies ist für ein effektives Krafttraining vorteilhaft, weil bei einigen Kräftigungsübungen am Ende einer Bewegung, aus biomechanischen Gründen, ein deutlich höherer Widerstand überwunden werden kann, als am Anfang der Bewegung. Die Widerstandskurve der Kraftübung deckt sich daher unter Verwendung eines einfügbaren, dehnbaren Verbindungselementes (16) besser mit der menschlichen Kraftkurve, als der konstante Widerstand bei Übungen gegen die Schwerkraft. Hieraus entsteht ein günstigerer Trainingsreiz als beim Training mit freien Gewichten, da jetzt der stärkste Bewegungsbereich und nicht der schwächte Bewegungsbereich einer Trainingsübung die Leistung limitiert.
2. 2. Der durch das einfügbare, dehnbare Verbindungselement (16) nach Patentanspruch 7 überbrückte Abschnitt der Schlingenkette (17) ist so kurz, dass das einfügbare, dehnbare Verbindungselement (16) auf die Länge der primär übergangenen Verbindungsschlinge gedehnt wird, bevor die trainierende Person ihren Bewegungsspielraum ausgeschöpft hat. In diesem Fall überwindet die trainierende Person über den gewählten Bewegungsbereich den Widerstand des einfügbaren, dehnbaren Verbindungselementes (16). Jede weitere Kraftentwicklung verläuft über die zuvor übergangenen Verbindungsschlingen (17). Damit verlässt die trainierende Person das dynamische Krafttraining hin zum statischen, wo sie ihre maximale willkürliche Kraft entwickeln kann. Dies ist auch der Fall, wenn das Ausmaß einer Übungsbewegung die maximale Dehnbarkeit eines einfügbaren, dehnbaren Verbindungselementes (16) überschreitet.

A distinction must be made between the following two possible applications:

1. 1. The elastic connection element ( 16 ) according to claim 7 bridged section of the loop or connecting chain ( 17th ) is so large that the end position of the training exercise is reached before the insertable, stretchable connecting element ( 16 ) to the length of the primarily skipped connecting loops ( 17th ) is stretched or its maximum extensibility is reached. In this case, the exercising person overcomes the resistance of the insertable, expandable connecting element over this range of motion (drawing 22). Compared to dynamic training with conventional strength training devices, which develop the same, weight-dependent training resistance over the entire range of motion, when a spring or rubber is stretched, the resulting resistance increases with increasing material stretch. This is advantageous for effective strength training, because with some strengthening exercises at the end of a movement, for biomechanical reasons, a significantly higher resistance can be overcome than at the beginning of the movement. The resistance curve of the strength exercise therefore coincides with the use of an insertable, stretchable connecting element ( 16 ) better with the human strength curve than the constant resistance in exercises against gravity. This results in a more favorable training stimulus than when training with free weights, since the strongest range of motion and not the weakest range of motion of a training exercise now limit the performance.
2. 2. The by the insertable, stretchable connecting element ( 16 ) according to claim 7 bridged section of the loop chain ( 17th ) is so short that the insertable, expandable connecting element ( 16 ) is stretched to the length of the primarily bypassed connecting loop before the exercising person has exhausted their range of motion. In this case, the exercising person overcomes the resistance of the insertable, stretchable connecting element over the selected range of motion ( 16 ). Any further development of force takes place via the connecting loops that were previously ignored ( 17th ). With this, the exercising person leaves dynamic strength training to static, where he can develop his maximum voluntary strength. This is also the case if the extent of an exercise movement exceeds the maximum extensibility of an insertable, extensible connecting element ( 16 ) exceeds.

Limiting dynamic training to certain joint angles or a certain range of motion is advantageous, for example, in the rehabilitation of certain injuries.

The possibility of insertable, stretchable connecting elements ( 16 ) with different (stretching) resistance curves enables the training resistance to be adapted to the training goal and the performance of the training person for a previously defined, possibly limited range of motion.

Another advantageous embodiment of the invention is specified in claim 8. The insertable force measuring element mentioned under claim 8 ( 19th ) can take the form of a Load cell or a strain gauge be designed. It is in the course of the loop or connecting chain ( 4th , 11 , 19th ) on two connecting loops ( 2 ) or connecting elements ( 10 , 15th ) reversibly attached. The force measuring element can be connected with two connecting elements ( 2 , 10 , 12th , 15th ) connected or in the connection chain ( 19th ) are inserted according to claim 3 (drawings 23 and 24).

An insertable force measuring element according to claim 8 in the course of the force transmission can determine the force developed during a certain exercise. This can be the maximum developed force or the force development over a certain load period (integral) of this exercise.

The training person learns how their strength performance is developing and can draw conclusions from this about the effect their training stimuli, their training break and other behavior have on it. Therefore, this strength measurement enables strength training, recovery times and other behaviors to be optimized so that the exercising person achieves their training goal faster. In addition, the knowledge of the measured force values can have a positive effect on the motivation of the exerciser.

This objective force measurement by means of a force measuring element is a more precise measuring instrument than comparing the moved load in conventional strength training with weight plates or dumbbells.

Another advantageous embodiment of the invention is specified in claim 9. The design of the variably attachable trunk loops ( 20th ) is the same or similar to the design of the trunk loop mentioned under claim 1 ( 1 , Drawings 25 and 26). A trunk sling that can be attached variably ( 20th ) is not connected directly to the connecting chains, but via an additional connecting loop at each of their ends ( 18th ). Through this indirect connection, exercises with power transmission from the foot loops ( 3 ) on one over the additionally attached trunk loop ( 20th ) lying element of the connecting chain ( 4th ) can be carried out without the additional trunk loop ( 20th ) is in the way of execution. With one or more additional trunk loops ( 20th ) attached to any connecting loop ( 2 ) or any connecting element ( 10 , 12th , 15th ) can be attached, the training person can adapt the training device described in claim 1 to their training needs so that different distances and thus joint angles are available for exercises that require power transmission from a torso sling to the ankle sling, without the connecting chain having to be adapted for this or an existing trunk loop needs to be relocated.

With this adaptation, the exercising person can, for example, change their exercise position during the leg press and squat exercises or switch between these exercises without having to adjust the training device mentioned under claim 1 in the meantime.

Another advantageous embodiment of the invention is specified in claim 10. The design of the variably attachable cross connection ( 23 ) between connecting loops of the loop chains according to claim 2 or between insertable or removable connecting elements of the connecting chains according to claims 3, 6, 7 and 8 corresponds, for example, to that of a connecting loop ( 2 ) made of tear-resistant material of larger dimensions (drawing 29). An alternative design, analogous to the loop chain ( 4th ) from connecting loops, through a chain of smaller cross-connecting loops.

The connection between the material ends of the cross-connecting loops ( 23 ) can be created, for example, by sewing together with tear-resistant yarn.

When training the leg muscles in the range of the maximum arbitrarily developable force, the leg press exercise has shown that the legs of the person exercising are pushed apart due to the construction of the mobile strength training device mentioned under claim 1. This makes it difficult for the person training to use their full strength potential during this exercise. The aforementioned advantageous embodiment according to claim 10 prevents the legs from diverging in that the connecting or loop chains ( 4th ) between the torso loop ( 1 ) and the ankle loops ( 3 ) are fixed against each other.

The invention mentioned under claim 1 and the subordinate claims 2 to 10 can be designed and developed in various ways. Some design examples of the invention according to claim 1 and the subordinate claims 2 to 10 are illustrated in the accompanying drawings.
