Physical Fitness and Anthropometrical Profile of the Brazilian Male Judo Team
Journal of Physiological Anthropology, 2007
The present study had as objectives (1) to compare the morphological and functional characteristics of the male judo players of the Brazilian Team A (nϭ7) with the judo players of Teams B and C (reserves; nϭ15), and (2) to verify the association between the variables measured. Thus, 22 athletes from the seven Olympic weight categories were submitted to: a body composition evaluation (body mass, height, ten skinfolds, eight circumferences, three bone diameters and percent body fat estimation); the Special Judo Fitness Test (SJFT); maximal strength tests (one repetitionmaximum, 1 RM, in bench press, row, and squat); and the Cooper test. One-way analysis of covariance was used to compare the groups. The relationships between variables were determined by the Pearson coefficient correlation. The significance level was fixed at 5%. No significant difference was found in any variable between them. The main significant correlations observed were between the following variables: VO 2 max and number of throws in the SJFT (rϭ0.79); percent body fat and estimated VO 2 max (rϭϪ0.83) and number of throws in the SJFT (rϭϪ0.70); chest circumference and bench press 1 RM (rϭ0.90) and in the row (rϭ0.80); and thigh circumference and squat 1 RM (rϭ0.86). However, there was no significant correlation between circumferences and 1 RM/kg of body mass. According to these results the main conclusions are: (1) the physical variables measured do not discriminate performance when analysis is directed to the best athletes; (2) a higher percent body fat is negatively correlated with performance in activities with body mass locomotion (Cooper test and the SJFT); (3) judo players with higher aerobic power performed better in high-intensity intermittent exercise; (4) judo players with bigger circumferences present bigger absolute maximal strength.

Casals, C, Huertas, JR, Franchini, E, Sterkowicz-Przybycień, K, Sterkowicz, S, Gutiérrez-García, C, and Escobar-Molina, R. Special judo fitness test level and anthropometric profile of elite spanish judo athletes. J Strength Cond Res 31(5): 1229–1235, 2017—The aim of this study was to determine the anthropometric variables that best predict Special Judo Fitness Test (SJFT) performance. In addition, anthropometric profiles of elite Spanish judo athletes were compared by sex and age category (seniors and juniors). In this cross-sectional study, a total of 51 (29 females) athletes from the Spanish National Judo Team were evaluated during a competitive period. All athletes performed the SJFT and underwent an anthropometric assessment through skinfold thickness measurements. Mann-Whitney comparisons by sex and age category showed that males had significantly higher muscle mass and lower fat mass than females (p < 0.001), whereas juniors and seniors exhibited few differences in body co...

This study aimed to compare the anthropometric profile and physical fitness of young judo and wrestling athletes. Twenty-four young athletes (judo (n = 13) and wrestling (n = 11)) participated in this study. The first visit involved anthropometric and flexibility evaluation, abdominal endurance test, upper limbs resistance and cardiorespiratory test. After 48 h, horizontal jump test (HJT), vertical jump test (VJT), medicine ball throw test (MBT), chin-up test (CUT), chin-up isometric test (CUIT) and the anaerobic resistance test were performed. Judo athletes presented greater values for body mass (p = 0.020), height (p = 0.010), and body mass index (p = 0.026) than wrestlers. Judo athletes also performed better for abdominal endurance (p = 0.044), upper limb resistance tests (p < 0.001), VJT (p = 0.022) and MBT (p = 0.023) than wrestling athletes. These results suggest that young judo athletes presented a higher performance in abdominal endurance, upper limbs resistance, HJT, VJT...
Problem and aim. Most of the preceding studies on SJFT have investigated the performance of various judokas in this test and less attention has been paid to correlation between specific judo actions and prominent attributes related to judo athletes' performance. The purpose of this study was to define the correlation between anthropometric and bio-motor attributes, and special judo fitness test. Methods. Fifty senior judokas (mean ± standard deviation: 20.75 ± 1.80 years old, 178 ± 4.20 cm of height and 21.32 ± 2.81 kg/m 2 of BMI) were assessed for some anthropometric and bio-motor variables, and also specific judo fitness level. Results. Height was in inverse relationship with SJFT (P<0.05). While, the same but a stronger relationship (P<0.01) was found regarding sitting height and fat free mass. Moreover, a significant direct correlation was observed between body fat percentage and SJFT. Similarly, lower body strength, vertical jump height and flexibility (P<0.05), and hand grip strength and anaerobic power (P<0.01) were in inverse relationship with SJFT index. In return, speed (P<0.01) and agility (P<0.05) were directly related to SJFT index. Conclusions. It seems that excellent performance in specific judo actions depends largely on muscularity and superiority in anaerobic metabolism because of its correlation with attributes such as fat free mass, strength, speed and anaerobic power.

Background & Study Aim: Body composition, maximum strength and the special judo fitness are determining factors to high-level judo performance. The aim of the present study was to relationships between indicators of body composition, maximum strength and special judo fitness can discriminate between judokas of different competitive levels who have yet to reach international status. Material & Methods: A total of 19 judokas, aged 24.3 ±5.3 years were divided into two groups, according to the titles or classification won in the previous 3 years in regional (RE) or state and national (SN) competitions. Body composition, the 1-RM test of squat, supine and a barbell row (B-Row), and the Special Judo Fitness Test index (SJFT-I) were applied to both groups. Results: Body fat (BF), fat-free mass (FFM), lean body mass (LBM) and body fat percentage (BFP) were not determining factors to indicate judokas level. However, 1-RM of the squat and B-Row test identified athletes with the best competit...
Background. Judo is an Olympic sport where physical fitness is of great importance as well as technique and tactics. Physical and physiological conditions of the athletes are very important for a better judo performance and there is still a need for more data related to these determinants. Problem and aim. There is a need for more data concerning anthropological determinants of judo athletes. Thus, the aim of this study was to evaluate anthropometric profile, Wingate and Special Judo Fitness Test (SJFT) performance. Methods. The following tests and measurements were conducted in order to investigate anthropometric profile, Wingate and Special Judo Fitness Test (SJFT) performance of male (n=7) and female (n=10) judo athletes from Turkish Olympic judo team: anthro-pometric measurements, Wingate anaerobic test (WanT) and SJFT. An independent Student t test was used to compare male and female athletes. Pearson product correlation was used to verify the relationship between variables. Effect sizes were calculated following the recommendations by Rhea (2004). Results. There were differences between male and female athletes in the following variables; fat-free mass, body fat percentage, peak and mean power, HR after the set A and in the SJFT index (p<0.05).Large and very large correlations were found between anthropometric measurements, SJFT parameters and WanT performance results (p<0.01). Large correlation was found between fat-free mass and HR values during SJFT sets (p<0.05). Conclusions. It can be concluded that the higher the fat percentage, the lower is the performance in activities involving body displacement. In conclusion, sex and weight differences should be taken into consideration while evaluating judo athletes and because higher fat-free mass means better SJFT performance, the training program should be organized to decrease or maintain body fat and increase muscle mass.
Physiological Profiles of Elite Judo Athletes
Sports Medicine, 2011
To be successful in international competitions, judo athletes must achieve an excellent level of physical fitness and physical condition during training. This article reviews the physiological profiles of elite judo athletes from different sex, age and weight categories. Body fat is generally low for these athletes, except for the heavyweight competitors. In general, elite judo athletes presented higher upper body anaerobic power and capacity than nonelite athletes. Lower body dynamic strength seems to provide a distinction between elite and recreational judo players, but not high-level judo players competing for a spot on national teams. Even maximal isometric strength is not a discriminant variable among judo players. However, more studies focusing on isometric strength endurance are warranted. Although aerobic power and capacity are considered relevant to judo performance, the available data do not present differences among judo athletes from different competitive levels. Typical maximal oxygen uptake values are around 50-55 mL/kg/min for male and 40-45 mL/kg/min for female judo athletes. As for other variables, heavyweight competitors presented lower aerobic power values. The typical differences commonly observed between males
Body composition and aerobic capacity of judokas and controls: A comparative study
IP Innovative Publication Pvt. Ltd., 2019
Introduction: Anthropometric parameters of judo players play an important role for success in combats. Aerobic capacity is significant in terms of optimal use of the judoka’s system and timely recovery process. Study was undertaken with objective to compare body build and aerobic capacity of judokas with untrained peers and understand changes in judokas due to training. Materials and Methods: Judo players (n=31) with minimum 3 years of training and who were in regular practice were included and compared with age matched medical students (n=31). Students who practice regular exercise regime were excluded. Anthropometric parameters were measured in terms of weight, height body mass index, seven site body circumferences, seven site skin fold thickness. Body fat percentage was further calculated as per standard formula. VO2max or the aerobic capacity was determined by using treadmill and following Bruce protocol. Results and Discussion: Control group showed significantly higher values for Skinfold thickness, body density and body fat % than judo group. Mean value of circumference of upper limb was more in judo players group. VO2max was more for Judo group 63.9ml/ kg/ min, than control 48.9ml/kg/min. Conclusion: The results of the study can be utilised as a means to understand the different physiological changes due to training in a player and also to optimise and upgrade the training regime so as to achieve best performance in the judo players. Keywords: Judo, VO2Max, Anthropometry, Body fat, Skinfold thickness.
Anthropometrical profile of elite Spanish Judoka: Comparative analysis among ages

Background Judo athletes usually try to maximize muscle mass and to minimize adiposity in each weight category, but few studies focused on comparisons of different age categories and little is known about sexual dimorphism among judo athletes. The aim of the study was to compare anthropometrical variables in male and female judoka from Spanish National Teams. Material/Methods: Eighty-seven national level Spanish judoka from all seven weight categories took part in this study: females (n=46)-cadet (n=16), junior (n=12) and senior (n=18); males (n=44)-cadet (n=18), junior (n=15) and senior (n=8). Body mass, height, skinfold thickness, circumferences and breadth anthropometric measurements were carried out. Somatotype components, body mass index, body fat and muscle mass were also estimated. A two way (gender and age groups) analysis of variance and Tukey test were used to compare groups. Results: (1) males were heavier, taller, had lower body fat and higher muscle mass absolute and relative values, circumferences and bone diameters, lower endomorphic and higher mesomorphic components than females; (2) for skinfold thickness males presented lower values in limbs' sites than females, but no difference was found in trunk skinfold thicknesses; (3) few differences were found among age categories, with cadets presenting smaller flexed arm circumference and humerus epicondyle bone breadth compared to junior and seniors, and lower absolute muscle mass compared to seniors; (4) tendency for reducing sexual dimorphism in some anthropological dimensions and in endomorphic and mesomorphic components was observed across age categories. Conclusions: Morphologically high level cadet judo athletes are quite similar to older athletes and coaches can select them from these ages. These data can be used as reference to coaches and physical conditioning professionals.
