DESCRIPTION

System for the evaluation and training of the isometric force by means of a guidance system.

Technical sector

This invention relates to a system that allows quantifying the isometric force performed by a subject.

State of the art

The isometric force is that in which the muscle contracted does not change its length, such as when trying to push a wall or close the hand tightly.

In sport climbing and in many other sports in which it is necessary to maintain a position for long periods of time, for example a climber attached to a dam of a vertical wall, it is very important to have a good isometric strength of the musculature responsible for the grip manual.

The increase in the number of participants in this sports specialty and the proliferation of urban climbing facilities, through climbing walls and competitive events, have contributed to the scientific interest, both physiological and psychological aspects, over climbing in recent years. In this sense, the force of manual grip seems to determine the performance in this sport to a greater extent. The method used to evaluate it in most climbing works has been the manual dynamometer. However, it is not considered a specific device to evaluate climbing strength. In this sense, there is a device that allows you to evaluate the strength of fingers in a very specific "barge" climbing dam and has been used in studies that evaluated the strength of fingers in climbers. However, there are many types of climbing grip and it has not yet been possible to assess in detail the force applied in each of them by the sports climber. Thus, the low presence of equipment and systems that reliably and accurately quantify the force developed by this group of athletes is remarkable. In addition, the proposed system has applicability in sport (climbing-training), rehabilitation and functional rehabilitation

Therefore, the present invention aims at developing a system that allows quantifying the isometric tensile force applied on the dam by a person when gripping or leaning on it.

The system object of the invention is composed of a guide or rail system which is screwed to the wall, a skate that moves vertically through the guide, a load cell placed on the skate, pulley, a grip system from of which the traction force is carried out and a system to fix the subject to the ground either by means of a weighted vest-harness or attached by rope to the wall. The load cell together with the pulley allows the isometric force of different muscle groups to be quantified accurately and in numerous positions.

In the event that the signal is transmitted to a microprocessor-based digital system (personal computer, mobile phone or similar), the system would add an external power system, a signal reception emission system, a computer and software in charge of Manage the data received.

We consider that the system for the evaluation and training of the isometric force by means of a guidance system will allow its use by professionals of the Physical Activity and Sports, for the control and assessment of the maximum isometric force in climbers, although it also has a great applicability in other sports, in rehabilitation and functional rehabilitation.

The following are some inventions of methods of analysis already registered, similar to the object of the invention:

DYNAMOMETER AND RELATED ASSESSMENT PROCEDURE ES2260486 T3: The invention relates to a dynamometer for evaluating the force exerted by the hand, comprising a frame, a pair of levers adapted to be grasped by a user and a spring-like opposition element. The main differences between this document and the proposed system are: 1) The proposed system is located on a portable platform and can also be extracted from the portable platform for use in other situations, such as a weight training machine. 2) The proposed system allows the place where the grip is made not to be a lever, but a climbing dam or any other type of grip. 3) The proposed system quantifies the tensile force, not compression. 4) The proposed system can be placed vertically, hung on a wall, to simulate a climbing wall, or held in different planes by the platform grips.

ICO ELECTRONIC TRAINING EQUIPMENT FOR CLIMBING SPORTS ES1076190 U: Refers to an electronic training equipment for climbing sports formed by a panel with grips, dams or reliefs that can be used as support by the climber or climbers to follow a route of ascent, lighting sensors and a computer to design the different routes. The object of this invention is to mark climbing routes, but does not quantify the isometric force performed by the athlete.

WIRELESS PRESSURE SENSING ROCK CLIMBING HANDHOLD AND DYNAMIC M ETHOD OF CUSTOMIZED ROUTING US8,668,626B1: The invention relates to a climbing dam which includes a microprocessor, pressure sensors and light emitters that wirelessly informs about the paths that The climber and support pressure must be followed. The main difference between this document and the new proposed system is that the proposed platform is portable, allows the place where the grip is made is not a lever, but a climbing dam or any other type of grip, it can be placed Vertical shape, hung on a wall, to simulate a climbing wall, or held in different planes by the platform grips and is removable for use in other sports activities.

DEVICE FOR ISOMETRIC DYNAMIC EXERCISE TRAINING TESTING

WO1998023335A1: It consists of a device composed of a harness attached to the ground which incorporates a dynamometer that is capable of measuring the isometric force of a subject by pulling the harness up. The harness is attached to the ground, so that extending the knees the system calculates the isometric force produced. The harness also allows the incorporation of elastic components to perform dynamic knee flexoextension exercises. The differences with the system proposed here are clear since this device is only applicable to knee flexion extension movements, and other types of measurements such as arm traction forces, external-internal shoulder rotation, abduction, upper limb adduction cannot be performed. and lower, etc. In addition, the harness has the function of pulling the dynamometer and is not ballasted as in the present development. In the system proposed here it incorporates a weighted vest-harness, which will be used or not depending on the test to be performed and the

subject strength On the other hand, the system for the evaluation and training of the isometric force by means of the proposed guide system is composed of a guide and skate system that allows adjusting the dynamometer height according to the exercise performed and the height of the subject, allowing innumerable positions and exercises, without limitations, and for both upper and lower limbs.

CH703458A2: This system consists of a bar which is connected to an electronic component for the evaluation of the isometric force. The system, extremely simple, does not allow to modify its height by means of any mobile system so it cannot be adapted to the height of the athlete or the type of exercise, being therefore limited isometric tests that can be performed. On the other hand, it does not have any system by which it is possible to block the athlete so that he does not lift his own body weight when performing the test.

WORKING PROCEDURE FOR PHYSICAL TRAINING MACHINES ES2289906A1: This system consists of a machine that allows, through a locking system, to cause a momentary isometric action to then unlock the system and be able to perform the movement. Thus, according to the inventors, once unlocked and after activating the elastic components of the muscle, the movement produced reaches great speed. Thus, the differences with the system for the evaluation and training of the isometric force by means of the proposed guidance system are clear since 1) the system proposed by us allows us to quantify the isometric force through a system adaptable to the subject's height and type of exercise , 2) the system proposed by this author is a training procedure that combines isometric force with dynamic force so it is used as a new training method by activating the elastic components of the muscle 3) the system proposed by this author does not allow quantification the maximum isometric force

JPS55149029A This system consists of a portable body strength meter that has a grip system by means of which the subject in traction calculates the force performed. The main differences with respect to the system for the evaluation and training of the isometric force by means of a guide system are that 1) the system proposed by us is composed of a guide and a skate that allows you to fix the wall on one side and adjust the apparatus at the height of the subject while the described system does not have any mechanism to adapt to the athlete's body parameters, 2) our system has a pulley that allows redirecting, by means of a cable, the direction of traction allowing multiple tests and tests physical, both upper and lower limbs. 3) our system adds the possibility of fixing to the wall to perform multiple physical tests that exceed the strength of the body weight itself, 4) our system allows the grip system to be interchangeable, so that it is possible to use different climbing dams , hand grips or a simple strip of wood or other material.

ISOMETRIC GRIP DEVICE AND METHOD OF EXERCISE US201106550A1. This system, similar to the previous JPS55149029A, allows the training of the isometric force by means of a portable and lightweight device consisting of two handholds that when traction measures the isometric force made by the subject and displays it on a screen. The main difference with the system for the evaluation and training of the isometric force by means of the proposed guidance system lies in 1) the system referred to here is precise for the measurement that both hands perform the traction in the opposite direction 2) our system is attached to the wall so it is not portable and thus allows it to work with one hand 3) our system has a guide and skate system that makes it possible to adapt to the individual's height and perform multiple tests and exercise, thanks to the ability to redirect the cable in a variety of directions

by having a pulley for this purpose, 4) our system allows the grip system to be interchangeable, so that it is possible to use different climbing dams, hand grips or a simple list of wood or other material.

WEIGHTED VEST US2013190144A1: This invention describes a weighted vest that obviously does not allow quantifying the isometric force. The only resemblance to our invention is that our system uses a weighted vest-harness whose function is not only to add load to the subject in those tests that the subject may lift his own body weight, but also to subject the individual to the ground so that This does not move. The difference between a weighted vest and a weighted harness is evident; Just as this patent, by itself, does not measure isometric force.

PORTABLE SYSTEM FOR THE EVALUATION AND TRAINING OF THE ISOMETRIC FORCE P201500186: This system consists of a portable system with a perforated surface on which the dynamometer is located that allows measuring the force realized, however the system proposed here, in addition to being a system fixed uses a guide and skate that allows a better regulation of the height at which the dynamometer can be placed, allowing a multitude of positions, not limited by the number of holes in the perforated platform. On the other hand, the dynamometer is fixed by a manual or electric brake so that it does not move during the execution of traction. Finally, the system is accompanied by a weighted vest-harness and with the possibility of being tied by rope, chain or similar to the guide bar. This system allows the subject to be unable to lift his own body when performing the exercise, accurately measuring the force he is able to perform. This contribution, together with that it is a fixed system and through a guide and skate, we consider it has inventive activity.

Explanation of the invention.

The present invention consists of a system that allows quantifying the maximum isometric pressure performed by a person by using a dynamometer or traction sensor.

The invention is applicable to the study of the isometric strength of climbers, and can be used in other physical activities or in rehabilitation.

For the measurement of isometric force in climbers and other exercises, the invention incorporates a dynamometer or traction sensor, which by means of a screw is attached at its upper end to a skate; which slides on a guide system or rail placed vertically and screwed on a wall. Because the skate along with the dynamometer moves along the rail, it is possible to modify its height according to the height of the subject to which we want to measure or the type of test we want to perform. The skate has a locking system, which can be manual or electrified so that, once placed in place, it does not move when exerting force on it. At the lower end of the dynamometer or traction sensor a cable, metal plate, or graduated chain is made of any other form or material resistant to traction, which on one side screwed to the force sensor and on the other to the climbing dam or any other type of grip, will be responsible for transmitting the tensile force made by the subject. Thus, the system allows the use of any type of dam or grip system, such as a bar to measure the tensile force of arms. In this case, between the dynamometer and the dam or grip where the athlete performs the traction, a pulley can be installed by means of a screw that will allow the force to be redirected in another direction, depending on the exercise performed.

A weighted vest with the possibility of being attached by means of a carabiner or similar to the guide system or to the wall, will prevent the subject, when performing the traction, from lifting his own body. In this way the system will be able to calculate the total force exerted, regardless of whether the subject is able to lift their own body weight, as scientific evidence has shown.

Once the tensile force is realized or during it, the dynamometer screen shows the isometric force performed. In the case of using a traction sensor or a dynamometer with external output, the signal produced once treated, can be sent via wireless, bluetooth, or similar, to a computer, mobile phone, etc.

Embodiment of the invention

The system for the evaluation and training of the isometric force through system

Guide, object of the present invention, comprises the following components:

a) A guide or rail system (1) made of metal, synthetic or natural material is bolted to the wall vertically.

b) A skate (2), placed on the guide, slides on it and can be locked by means of a clip, screw or similar (12). The skate can only move linearly on the guide, and it cannot be moved or removed from the guide. The skate can be placed, after loosening the brake or clip, at the desired height depending on the height of the subject performing the exercise. The guide or rail has anchors (3) to be firmly attached to the wall, floor or any other plane.

c) A locking system (12) by means of a clip, screw or similar, which allows the skate to be locked on the guide.

d) A measuring element (4), which may be a dynamometer or traction sensor that will record the load received by the climber or athlete when driving on it. The measuring element is screwed (5) to the skate and will move alongside it to be placed at the desired height.

e) A tensile element (6), which can be a plate, cable or graduated chain for transmitting the force to the measuring element.

f) Force transmission pulley (7): In the case of using a cable (6) as a force traction system, a pulley placed in line with the dynamometer allows, in the case of using a traction system different from the dam, direct the traction cable towards the subject that applies the force.

g) A clamping element (8), composed of a dam or a handle, which together with the tensile cable of the dynamometer, allows the subject to comfortably perform the traction to measure the isometric force that is capable of developing.

h) Weighted vest-harness (9), which will be used in the event that the subject exceeds the force produced by his own weight, which will also have a grip system via cable (11) carabiner or similar to the guide ( 10)

i) Signal emission-reception system: There is the possibility of using a traction sensor, a data acquisition system and wireless emission-reception to send the data to a microprocessor-based digital system (personal computer, mobile phone or similar) ).

j) Power supply: In case of using a traction sensor and wireless signal delivery system, an external power system will allow the system to be powered.

k) A microprocessor-based digital system for the treatment of the data generated by the measurement element and specific software for this treatment.

Other shapes, sizes and types of dynamometer or traction sensor grip systems are also estimated herein, depending on their usefulness.

The following briefly summarizes the mode of use of the SYSTEM FOR THE EVALUATION AND TRAINING OF THE ISOMETRIC FORCE THROUGH THE GUIDE SYSTEM:

Isometric strength evaluation climbing:

The complete system is placed in the place where the measurement will be carried out, for example a wall, and attached to the chosen plane taking advantage of the grip holes (3). Then the skate / dynamometer will slide in the most appropriate position, depending on the height of the subject and the test to be performed. Once the position of the skate is determined, it will be locked using the clip or screw. Next, the subject will grab the prey or grab and pull the system. This traction will be transmitted to the dynamometer, which will show the isometric force exerted on the screen.

Evaluation of the isometric force by pulley:

In the case of not using a climbing dam, but another grip system that involves a different angle of traction, the cable will pass through the pulley, allowing the direction of traction to be modified.
