Description

ARNÉS DE ENTRENAMIENTO PARA JUGADORES DE TENIS DE  TRAINING HARNESS FOR TENNIS PLAYERS
MESA CAMPO DE LA INVENCIÓN  TABLE FIELD OF THE INVENTION
La presente invención está situada en el campo del diseño de dispositivos de entrenamiento deportivo, más particularmente el diseño de dispositivos para mejorar el rendimiento de los jugadores de tenis de mesa. ANTECEDENTES DE LA INVENCIÓN The present invention is located in the field of design of sports training devices, more particularly the design of devices to improve the performance of table tennis players. BACKGROUND OF THE INVENTION
Un experto en la técnica del campo tecnológico correspondiente, conoce que la ergonomía es la ciencia multidisciplinar que tiene como finalidad la adecuación de los productos, sistemas y entornos artificiales a las características, limitaciones y necesidades de sus usuarios, para optimizar su eficacia, seguridad y confort (Fairer, 1997). Este es uno de los campos más estudiados en el mundo deportivo pues busca mejorar el rendimiento, reducir riesgos y salvaguardar la salud de los deportistas. An expert in the corresponding technological field technique knows that ergonomics is the multidisciplinary science whose purpose is the adaptation of artificial products, systems and environments to the characteristics, limitations and needs of its users, to optimize its effectiveness, safety and comfort (Fairer, 1997). This is one of the most studied fields in the sports world because it seeks to improve performance, reduce risks and safeguard the health of athletes.
En el ámbito particular de los jugadores de tenis de mesa, se reconoce que la postura corporal del o los jugadores durante su desempeño deportivo es uno de los factores determinantes en el resultado del juego. De ahí que los entrenadores de este deporte centren su atención en reforzar la memoria sensorio-motriz de los aprendices a través de correcciones dirigidas durante las sesiones de entrenamiento. In the particular field of table tennis players, it is recognized that the body posture of the player or players during their sports performance is one of the determining factors in the outcome of the game. Hence, the coaches of this sport focus their attention on reinforcing the sensory-motor memory of the trainees through corrections directed during the training sessions.
Normalmente, el jugador de tenis de mesa debe aprender las mejores posturas de acuerdo con los tipos de golpe que realiza durante el juego; este aprendizaje se logra mediante diversas experiencias tales como el estudio de certámenes deportivos en los que participan jugadores profesionales y la supervisión del entrenador durante la práctica deportiva. Estas actividades permitirán que el cerebro del jugador se encuentre completamente adaptado y capacitado para responder eficientemente durante los certámenes deportivos. Uno de los inconvenientes más comunes que suele presentarse en los aprendices de tenis de mesa es el desconocimiento de las posturas apropiadas para el mejor rendimiento durante el juego y peor aún, la creación de malos hábitos posturales que perjudican su aprendizaje, avance y desempeño durante las sesiones de juego. Normally, the table tennis player must learn the best positions according to the types of blow he performs during the game; This learning is achieved through various experiences such as the study of sports competitions in which professional players participate and the supervision of the coach during sports. These activities will allow the player's brain to be fully adapted and trained to respond efficiently during sports competitions. One of the most common inconveniences that usually occurs in table tennis apprentices is the lack of knowledge of the appropriate postures for the best performance during the game and even worse, the creation of bad postural habits that impair their learning, progress and performance during the game sessions
Es usual que las personas no sean conscientes de todos los movimientos de su cuerpo mientras hacen uso de su implemento de juego, en especial, la posición de sus extremidades superiores durante los golpes con la raqueta. Los demás aspectos del golpe tales como la posición del cuerpo, la ubicación de la bola, el efecto, la velocidad, entre otros, sí son posibles de modificar conscientemente pero para la persona que inicia la práctica deportiva no es natural lograr la postura óptima de las extremidades superiores, en particular del codo. It is usual that people are not aware of all the movements of their body while making use of their game implement, especially the position of their upper extremities during racket strokes. The other aspects of the blow such as the position of the body, the location of the ball, the effect, the speed, among others, are possible to modify consciously but for the person who starts the sport it is not natural to achieve the optimal posture of the upper extremities, particularly the elbow.
La posición del codo es verdaderamente esencial en el desempeño del jugador de tenis de mesa. La posición correcta es a una distancia intermedia del tronco; ni lejos del trono ni cerca de este. El golpe de drive debe terminar al frente de la ceja. Solo en los golpes más avanzados, dicho golpe puede terminar más arriba con el fin de generar más fuerza. The position of the elbow is truly essential in the performance of the table tennis player. The correct position is at an intermediate distance from the trunk; neither far from the throne nor near it. The drive hit must end in front of the eyebrow. Only in the most advanced blows, can such a blow end higher in order to generate more force.
Para ejecutar un golpe de drive, el brazo debe retroceder a una distancia tal que el codo no sobrepase la linea eje que se forma entre tos hombros. Para ejecutar un golpe de revés, la raqueta debe iniciar el movimiento desde el frente del cuerpo, controlando la posición del codo de igual forma que en el golpe de drive. El golpe de revés se debe ejecutar procurando hacer el movimiento solo con el antebrazo y la muñeca. La inclinación del tronco es importante para el equilibrio del cuerpo. La posición del brazo que no ejecuta el golpe es muy importante para el equilibrio del cuerpo, al igual que para una buena técnica gestual. To execute a drive stroke, the arm must retreat at a distance such that the elbow does not exceed the axis line formed between the shoulders. To execute a backhand stroke, the racket must start the movement from the front of the body, controlling the position of the elbow in the same way as in the drive stroke. The reverse blow must be executed trying to make the movement only with the forearm and wrist. The inclination of the trunk is important for the balance of the body. The position of the arm that does not execute the blow is very important for the balance of the body, as well as for a good gestural technique.
Otro inconveniente presentado es que el jugador de tenis de mesa no está exento de sufrir lesiones al igual que cualquier otro deportista. Las lesiones más frecuentes en el tenis de mesa son las patologías de hombro, codo, muñeca y síndrome del túnel carpiano, en el caso de los miembros superiores del cuerpo humano; traumatismos oculares en el caso de cráneo y cara; lumbalgias y dorsalgias en el caso de raquis; tendinitis rotuliana y lesiones ligamentosas en el caso de rodilla; tendinitis aquilea en el caso de la pierna; esguince de tobillo; fractura de estrés en metatarsianos en el caso del pie; contracturas musculares, sobrecargas, desgarros musculares o tirones y rupturas fibrilares en el caso de lesiones musculares. Another drawback presented is that the table tennis player is not exempt from suffering injuries just like any other athlete. The most frequent injuries in table tennis are the pathologies of shoulder, elbow, wrist and carpal tunnel syndrome, in the case of upper limbs of the human body; eye trauma in the case of skull and face; low back pain and back pain in the case of rachis; patellar tendonitis and ligamentous lesions in the case of knee; Aquilea tendonitis in the case of the leg; ankle sprain; stress fracture in metatarsals in the case of the foot; muscle contractures, overloads, muscle tears or pulls and fibrillar ruptures in the case of muscle injuries.
En el estado de la técnica existen pocas propuestas en materia de dispositivos ergonómicos que permiten superar tos problemas anteriormente señalados. Algunas de estas son: In the state of the art there are few proposals regarding ergonomic devices that allow to overcome the problems mentioned above. Some of these are:

Pero si el jugador se inclina hacia el frente, el sensor de movimiento (2d) deja de sonar. The motion sensor (2d) causes a sound when the player is in an inappropriate position for the game, for example, standing and straight. But if the player leans forward, the motion sensor (2d) stops sounding.
El grado de inclinación del torso es importante de acuerdo con las diferentes jugadas por realizar. Si una bola viene cortada, el jugador debe agacharse mucho para subir la bola con impulso. Si el jugador desea realizar un golpe básico, es menor la inclinación, pero nunca es apropiado que el torso esté recto porque el jugador puede perder el equilibrio y restringir su libertad de movimiento. The degree of inclination of the torso is important according to the different moves to be made. If a ball is cut, the player must bend down to raise the ball with momentum. If the player wishes to perform a basic hit, the inclination is less, but it is never appropriate for the torso to be straight because the player can lose his balance and restrict his freedom of movement.
