Relationship between aerobic and anaerobic power, and Special Judo Fitness Test (SJFT) in elite Iranian male judokas

Abstract

Introduction: The purpose of this study was to assess the relationship between aerobic and anaerobic power, and special judo fitness test in elite male judokas. Method: Nineteen elite Judokas [age 24.3 (3.1) yr, height 1.78 (.06) m, body mass 76.4 (11.2) kg, body mass index 20.2 (3.6) kg·m −2 and body fat 11.0 (1.8)%] performed a graded exercise test in treadmill, the Wingate anaerobic test for arms and the special judo fitness test. The graded exercise test in treadmill estimated maximal oxygen uptake (VO 2 max) and the Wingate anaerobic test assessed peak and mean power, descriptors of short-term power output and local muscular endurance respectively. Results: The index of special judo fitness test was in inverse direct relationship with VO 2 max (r = -.87, p < .01), peak power (r = -.74, p < .01) and mean power (r = -.62, p < .05). Discussion: Based on these findings, it was showed that the special judo fitness test is a field test that describes chiefly aerobic power, and in a lesser degree short-term power output and local muscular fatigue. Therefore, its further use from judo coaches and fitness trainers as a measure to monitor aerobic power is recommended, and the need for a field test that will describe anaerobic power is highlighted. PALABRAS CLAVE Pruebas de ejercicio de campo y laboratorio; Artes marciales Relación entre potencia aeròbica y anaeròbica y el Special Judo Fitness Test (SJFT) en judocas masculinos iraníes de élite ResumenIntroducción: El objetivo de estudio fue la evaluación de la relación entre las potencias aeróbica y anaeróbica, así como la prueba especial de aptitud física para el judo en los judokas masculinos de élite. Método: Diecinueve judokas de élite----edad 24,3 (3,1) años, altura 1,78 (0,06) m, masa corporal 76,4 (11,2) kg, índice de masa corporal 20,2 (3,6) kg·m 2 y grasa corporal 11,0 (1,8)%----realizaron una prueba de esfuerzo en cinta, la prueba anaeróbica de Wingate para brazos, y la prueba especial de aptitud física para el judo. La prueba de esfuerzo en cinta calculó la captación máxima de oxígeno (VO2max) y la prueba anaeróbica de Wingate evaluó la potencia máxima y media, que describen el rendimiento a corto plazo y la resistencia muscular local, respectivamente. Resultados: El índice de la prueba especial de aptitud física para el judo guardó una relación directa inversa al índice VO2max (r = −0,87, p < 0,01), potencia máxima (r = −0,74, p < 0,01) y potencia media (r = −0,62, p < 0,05). Discusión: Basándonos en estos hallazgos se ha demostrado que la prueba especial de aptitud física para el judo es una prueba de campo que describe principalmente la potencia aeróbica, y en menor grado el rendimiento a corto plazo y la fatiga muscular local. Por tanto, se recomienda su uso a los entrenadores de judo y a los monitores de entrenamiento físico como medida de supervisión de la potencia aeróbica, resaltando la necesidad de una prueba de campo que describa la potencia anaeróbica.

Relación del Special Wrestling Fitness Test con el rendimiento aeróbico

“…Una prueba de campo ampliamente utilizada con atletas de judo es el Special Judo Fitness Test (SJFT) 5 , con la cual se han reportado diferencias entre atletas de diferente nivel competitivo 6 , y su relación con el rendimiento aeróbico y anaeróbico 7 . Debido a las características comunes entre lucha olímpica y judo, el SJFT recientemente ha sido adaptado a lucha olímpica con el nombre de Special Wrestling Fitness Test (SWFT) 8-10 , reportándose su relación con el rendimiento aeróbico medido de forma indirecta 9,10 .…”

Psychometric Suitability of Adaptations to the Special Judo Fitness Test for Athletes With Visual Impairment

“…These finding have usually been attributed to the fact that elite athletes have a higher volume of judo-specific training (Drid et al, 2015) and, consequently, are able to perform better on specific motor tasks like number of throws (Franchini et al, 2005;Sterkowicz-Przybycie n et al, 2019). The HR measures after the test indirectly estimated the athlete's aerobic fitness (Hesari et al, 2014), but due to its high variability, it may not be a good marker to discriminate groups.…”

“…Each partner should be positioned six meters apart, and the executant should run to each partner to throw him/her as many times as possible. The SJFT indirectly estimates the athletes' aerobic capacity (heart rate after the test) and anaerobic capacity (number of throws) (Hesari et al, 2014;Sterkowicz & Franchini, 2001), and it has been reported to be predominantly anaerobic, although there have been higher values of oxygen uptake during the test (Franchini et al, 2011). In addition, this test has distinguished between athletes of different competitive levels (Franchini et al, 1998;Katralli & Goudar, 2012) and weight categories (Sterkowicz & Franchini, 2001), and it has detected changes in physical performance after a periodized training program (Marques et al, 2017).…”

Aerobic Capacity and Restitution Efficiency Level in Relation to the Training Experience and Weekly Training Volume of Male and Female Judo National Team Members in the Cadet Age Group (U18) during the Preparatory Period

“…However, these studies were performed on athletes competing at the national level and during the transition period (one–two weeks after the respective main competitions) [ 18 ]. Moreover, previous research shows that the result of judo fight is significantly correlated with the level of judo special skills [ 19 , 20 ]. Those skills are determined by the level of aerobic capacity in the cadet age group [ 21 ].…”
