“…In all loads, the ratio of peak power of the dominant right hand to the nondominant left hand is greater in females than in males for hand grip. According to Aoki and Demura, 25 females have a larger difference of maximum grip strength between dominant and nondominant hands. In addition, the moving velocity of loads was significantly greater in all loads for females and in lighter loads (20% to 50% of MVC) for males.…”

Purpose:This study aimed to compare the laterality, and its gender difference, of hand grip and elbow flexion power according to load in right hand–dominant individuals.Results:The subjects were 15 healthy young males (age 22.1 ± 0.7 y, height 171.3 ± 3.4 cm, mass 64.5 ± 4.1 kg) and 15 healthy young females (age 22.4 ± 1.0 y, height 161.1 ± 3.0 cm, mass 55.4 ± 4.6 kg). Isotonic peak power was measured with 6 different loads ranging from 20% to 70% of maximum voluntary contraction (MVC) for grip and elbow flexion movements.Results:The peak power was significantly larger in males than in females in both movements (ratio, males:females was 58.1:49.4%). The dominant right hand had larger peak power in all loads for hand grip power (ratio, dominant:nondominant was 83.6:71.1%) and in loads of 20% to 50% MVC for elbow flexion power (88.7:85.7%) in both genders, confirming laterality in both movements. The peak power ratio of the dominant right hand to the nondomi-nant left hand was significantly larger in hand grip than in elbow flexion for all loads in females.Conclusion:Even though laterality was confirmed in both grip and elbow flexion, gender difference is more marked in hand grip.

This study examines gender differences and laterality in maximal handgrip strength and controlled force exertion (CFE) in young adults. The subjects were 75 healthy young males (mean age 19.6 ± 1.6 yrs.) and 50 healthy young females (mean age 20.9 ± 1.9 yrs.). Maximal handgrip strength was measured twice. The subjects performed the CFE test three times after one practice trial. They matched their handgrip strengths to the demand values, which constantly changed and ranged from 5 to 25% of maximal handgrip strength. The difference between the demand value and the grip exertion value was used as an estimate of CFE. Maximal handgrip strength was significantly larger in males than in females in both the dominant and non-dominant hands, and was significantly larger in the dominant hand in both males and females. Insignificant gender differences were found in CFE of both hands. CFE was significantly superior in the dominant hand in both genders. In conclusions, gender differences are present in maximal handgrip strength of the dominant and non-dominant hands in young adults, but not in CFE of both hands. Laterality exists in maximal handgrip strength and in CFE for both genders

“…Bonitch-Góngora et al (2013) Élite ( En la comparación entre géneros, los datos indican que los judokas masculinos sénior (Claessens et al, 1984;Franchini et al, 2005b) desarrollan más pico de fuerza isométrica que las judokas femeninas sénior (Leyk et al, 2007;Little, 1991), lo que está de acuerdo con otros estudios sobre la influencia del género en la capacidad de desarrollar fuerza en la mano (Aoki & Demura 2008;Dopsaj et al, 2007). Según algunos autores, esto puede deberse a la mayor masa muscular de los hombres (Imrhan, 2003;Nevill & Holder, 2000;Peebles & Norris 2003;Peolsson, Hedlund, & Oberg, 2001;Ruiz-Ruiz, Mesa, Gutiérrez, & Castillo, 2002), sobre todo en la parte superior del cuerpo (Miller, Macdougall, Tarnopolsky, & Sale, 1993).…”

“…Son numerosos los factores que influyen en el resultado del pico de fuerza isométrica máxima en la prensión manual. Así, por ejemplo, la fuerza del agarre en la mano dominante alcanza su pico máximo entre los 18 y 31 años en hombres y entre los 31 y 59 años en mujeres, y desciende significativamente después de los 60 años de edad (Budziareck, Duarte, & Barbosa-Silva, 2008), los hombres poseen mayores picos de fuerza y de potencia en el agarre que las mujeres (Aoki, & Demura 2008;Dopsaj et al, 2007;Leyk et al, 2007), la masa corporal correlaciona positivamente con la fuerza del agarre (Coelho e Silva, Figueiredo, Carvalho, & Malina, 2008), y los sujetos con mayor perímetro del antebrazo poseen mayores valores de fuerza en el agarre (Nicolay & Walker, 2005). En esta línea, se ha encontrado una relación positiva entre la masa corporal y el pico de fuerza en la prensión manual en judokas (Thomas, Cox, LeGal, Verde, & Smith, 1989), diferencias entre judokas de distintos grupos de edad (Little, 1991), y diferencias entre hombres y mujeres judokas en ambas manos (Franchini et al, 1997), aunque en esta investigación, cuando los datos se presentaban relativos a la masa corporal no se encontraron diferencias.…”

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.
