Abstract

Counter-force system for eccentric exercise equipment, embodied by a system for use in physical-exercise equipment pertaining to the field of articles for gymnastics, which was developed specifically for eccentric exercises; weight-training equipment, known in the prior art, makes use of weights, called weight rings, which are attached to hand bars or pedals by means of cables and are dependent on gravity, traction on the cable being initiated as a force acting against the prevailing force of gravity, which does not make it possible to perform an exclusively eccentric exercise; with a view to resolving this drawback, the subject matter of the present patent application was developed, the invention comprising an operating system for weight-training equipment (1), wherein the initial movement of the pedal or hand bar (2) of the physical-exercise equipment (5) is performed without effort on the part of the user and upon reaching a specific position of the travel thereof the system then automatically exerts force in the opposite direction in order to return the pedal or hand bar to the initial position thereof.

Description

"SISTEMA DE CONTRA FORÇA PARA EQUIPAMENTO DE EXERCÍCIO EXCÊNTRICO"  "STRIKE SYSTEM FOR EXCENTRIC EXERCISE EQUIPMENT"

É ainda, objetivo do presente pedido, apresentar um sistema de contra força para equipamento de exercício excêntrico com baixos custos para sua exequibilidade industrial, porém aliado aos requisitos de robustez, segurança e praticidade utilitária, oferecendo assim ao público consumidor, uma opção adicional no mercado de congéneres, que ao contrário dos métodos de anilhas de peso usuais, oferece inúmeras possibilidades e benefícios a seus usuários, tornando-se um sistema de grande aceitação no mercado consumidor.  It is also the object of the present application to present a counter force system for eccentric exercise equipment with low costs for its industrial feasibility, but coupled with the requirements of robustness, safety and utilitarian practicality, thus offering the consumer public an additional option in the market of congeners, which unlike the usual weight washers methods, offers numerous possibilities and benefits to its users, becoming a system of great acceptance in the consumer market.
Histórico da invenção  History of the invention
Como é sabido, notadamente por técnicos no assunto, a atividade locomotora é a combinação de diferentes formas de ações musculares, que também podem ser encontradas de forma isolada. As is well known, notably by Subject matter, locomotor activity is the combination of different forms of muscular actions, which can also be found in isolation.
Na forma isolada temos três tipos de ações musculares diferentes: isométricas, concêntricas e excêntricas. Na forma combinada temos, por exemplo, um ciclo alongamento- contração, onde uma ação excêntrica precede imediatamente uma ação concêntrica, fato facilmente notado quando analisamos passos de uma caminhada ou a manipulação de algum objeto que nos cerca.  In the isolated form we have three different types of muscular actions: isometric, concentric and eccentric. In the combined form we have, for example, an elongation-contraction cycle, where an eccentric action immediately precedes a concentric action, a fact easily noticed when we analyze steps of a walk or the manipulation of some object that surrounds us.
Entretanto existem várias diferenças entre ações musculares concêntricas e excêntricas, que repercutem de maneira diferenciada no organismo humano, fato que deve servir de fonte para a manipulação de variáveis durante a prescrição de atividades físicas para a população em geral, ou para a planificação do treinamento de atletas.  However, there are several differences between concentric and eccentric muscular actions, which have a different repercussion on the human organism, a fact that should serve as a source for the manipulation of variables during the prescription of physical activities for the general population, or for the planning of training of athletes
Ações musculares concêntricas ocorrem quando há o encurtamento de um músculo envolvido em determinado movimento (quando erguemos um peso). Ações musculares excêntricas ocorrem quando os músculos envolvidos no movimento alongam-se de forma controlada (quando abaixamos um peso). Ocorre uma ação muscular isométrica quando um músculo é ativado e desenvolve força sem causar movimento em uma articulação. Este modo de ação é à base da manutenção postural.  Concentric muscle actions occur when there is shortening of a muscle involved in a certain movement (when we lift a weight). Eccentric muscle actions occur when the muscles involved in the movement elongate in a controlled way (when we lower a weight). An isometric muscle action occurs when a muscle is activated and develops force without causing movement in a joint. This mode of action is the basis of postural maintenance.
Fisiologia neuromuscular  Neuromuscular physiology
O tipo de ação muscular empregada oferece diferentes estímulos ao sistema neuromuscular. Estudos verificaram através de menor ação eletromiográfica, que ações excêntricas ativam um menor número de fibras musculares. Menos unidades motoras recrutadas indicam que mais força por unidade de músculo é produzida, e menos estimulação neural é necessária para a realização do movimento, mostrando uma eficiência neuromuscular maior das ações excêntricas. É sugerido que as adaptações neurais se dão de forma mais rápida quando se dá ênfase na fase excêntrica. The type of muscular action employed offers different stimuli to the neuromuscular system. Studies have verified through a smaller electromyographic action, that eccentric actions activate a smaller number of muscular fibers. Fewer recruited motor units indicate that more force per unit of muscle is produced, and less neural stimulation is required for movement, showing greater neuromuscular efficiency of the eccentric actions. It is suggested that neural adaptations occur more rapidly when emphasis is placed on the eccentric phase.
Menos unidades motoras recrutadas, usando o mesmo limiar de despolarização pode ser o fator responsável por este fenómeno. Este conhecimento pode ser usado, por exemplo, para a manipulação de variáveis durante a reabilitação de um membro lesionado.  Fewer motor units recruited using the same depolarization threshold may be the factor responsible for this phenomenon. This knowledge can be used, for example, for the manipulation of variables during rehabilitation of an injured limb.
Pontos deficientes do estado da técnica  Poor points of the state of the art
O grande inconveniente dos modelos de equipamento para musculação está no fato de que utilizam massas, conhecidas como anilhas de peso, para exercerem a força nas suas barras ou pedais.  The major drawback of bodybuilding equipment models is that they use masses, known as weight washers, to exert force on their bars or pedals.
Mais especificamente essas massas são posicionadas em trilhos verticais e fixadas nas extremidades de cordames ou cabos, os quais são direcionados aos pedais ou às barras de manipulação por meio de roldanas, sendo que ao se tracionarem os cabos, as anilhas de peso são deslocadas de sua posição de repouso, e exercem sempre uma força descendente.  More specifically, these masses are positioned on vertical rails and fixed to the ends of ropes or cables, which are directed to the pedals or to the handling bars by means of pulleys, whereby the cables are drawn, the weight washers are moved from their resting position, and always exerts a downward force.
O grande inconveniente desse sistema de força está no fato de que, por depender da ação gravitacional, ao se iniciar a tração no cabo a força já está atuante.  The great drawback of this force system lies in the fact that, depending on the gravitational action, when the traction starts in the cable the force is already acting.

The present invention relates to the use of pneumatic, hydraulic or similar piston for the operation of the eccentric exercise apparatus, the operation of which comprises a first movement, actuated by the user, actuated by pedal, bar manual or similar, that is the concentric, in this movement the user will not make any force, and when this movement reaches a certain amplitude the system begins to exert a certain force, in order to return the movement, being that in that return the piston exercises the opposing force and the user makes the force only in that phase of the exercise, which is the eccentric exercise.
A força exercida pelo pistão na sua movimentação de retorno pode ser ajustada convenientemente através dos dispositivos de vazão ou similares.  The force exerted by the piston in its return movement can be conveniently adjusted through the flow devices or the like.
