La fuerza isométrica del agarre en judo

Abstract

REVISIÓN ResumenDebido a que el agarre es un importante aspecto técnico-táctico a través del cual los judokas imponen su dominio sobre el adversario, dificultando que éste pueda realizar las técnicas de ataque oportunas y favoreciendo las propias, los judokas deben poseer altos niveles de fuerza isométrica y resistencia a este tipo de fuerza en la musculatura prensora de los antebrazos, como uno de los aspectos fundamentales para alcanzar el éxito. Este artículo revisa los perfiles de fuerza y resistencia muscular del agarre de judokas de diferentes sexos, edades y niveles competitivos. En general, el pico de fuerza isométrica de los judokas de élite no ha variado en los últimos 40 años y no parece diferenciarse del alcanzado por judokas de menor nivel competitivo o incluso del registrado en grandes grupos de población, lo que indica a los investigadores que la resistencia a la fuerza isométrica de prensión manual puede ser un parámetro más relevante en la evaluación de los judokas que el pico de fuerza isométrica, ya que en los combates deben mantener el agarre de manera continua durante periodos de tiempo relativamente largos y la fuerza máxima no se mantiene durante mucho tiempo. Sin embargo existen pocos estudios sobre la capacidad de resistir a sucesivas tensiones isométricas de prensión manual en judokas.Palabras clave: Fuerza isométrica; agarre; kumikata; judo; rendimiento. Handgrip isometric strength in judo AbstractThe grip is an important technical and tactical aspect through which the judokas dominate the adversary, hindering the application of appropriate techniques and favoring their own attack. The judokas must have high levels of isometric force and endurance to this type of force on the gripping muscles of the forearms, as one of the key aspects for success. This article reviews the grip muscular strength and endurance profiles of judokas of different groups (gender, age and competitive level). In general, the peak isometric strength of elite judokas has not changed in the last 40 years and is similar to that reached by non-elite judokas or even registered in large populations. This indicate that the evaluation of the isometric hand grip endurance may be a more relevant parameter than the peak isometric force in judokas, as during the bouts the grip must be maintained for relatively long periods of time and the maximum force cannot be maintained for long. However there are few studies on the ability to resist successive isometric handgrip stress in judokas.Keywords: Isometric strength; grip; kumikata; judo; performance A força isométrica da preensão em judo ResumoDado que a preensão é um aspeto técnico-tático muito importante, através do qual os judocas impõem o seu domínio sobre o adversário, dificultando que a este possa realizar as técnicas de ataque oportunas e favorecendo as próprias, os judocas aplicam altos níveis de força isométrica e resistência a este tipo de força muscular.

Physical fitness of amateur paddle players: comparisons between different competitive levels

“…The test used for handgrip endurance strength (HES) measurement consists of eight 10-s maximum isometric contractions with a passive interval of 10 seconds, which is sensitive to detect differences between different competitive levels (Bonitch-Góngora et al, 2013). The subject sited in a chair with the back supported and feet on the floor, with neutral shoulder adduction and rotation, 90° elbow flexion, forearm in neutral position and extended wrist between 0 and 30°, with an ulnar deviation between 0 and 15°.…”

“…It is important to point that the ability to Physical fitness in amateur paddle tennis | 43 produce muscular strength at high speed is essential for racket sports and anaerobic power is required in highly explosive movements (Groppel & Roetert, 1992). For the paddle tennis match, the handgrip isometric strength is also relevant, especially to execute successive actions holding the racket (Zanchet & Del Vecchio, 2013), and has been associated with a greater chance of success in some sports modalities (Bonitch-Góngora & Almeida, 2014). From the aerobic point of view, the game intensity is close to the demand of individual tennis, as well as the VO2 of players from both sports is similar in both maximum (55.64 ± 8.84 ml -1 •kg -1 •min) and mean values during the game (Hoyo et al, 2007).…”

Effect of official judo matches on handgrip strength and perceptual responses

“…Several parameters have been used by coaches to monitor fatigue and recovery during training or competition, and RPE is one of the most employed because of its ease of use and applicability in different combat sports ( Slimani et al, 2017 ). In the same way, the evaluation of handgrip strength during training or competition may provide important information for load control and recovery strategies, since it is considered a determining factor of judo performance ( Bonitch-Góngora and Almeida, 2014 ; Bonitch-Góngora et al, 2013 ; Calmet et al, 2010 ). However, to the best of our knowledge, handgrip strength has not been evaluated in an official competition.…”

Descripción de la aptitud física en judokas sub-15 argentinos

“…El judo tiene una estructura temporal de característica intermitente, dada por un periodo de trabajo de intensidad elevada, seguida por periodos de pausa incompleta (Miarka et al, 2012). Durante los periodos de trabajo, los judokas realizan múltiples acciones de alta complejidad que incluyen tracciones, empujes y sujeciones en búsqueda del control o la rotura del kumikata (agarre) que demandan considerables niveles de fuerza y resistencia en los miembros superiores (Franchini, Miarka, Matheus, et al, 2011;Bonitch-Góngora & Almeida, 2014). Simultáneamente, se realizan esfuerzos explosivos de los miembros inferiores al ejecutar proyecciones en acciones de ataque (Detanico et al, 2012).…”
