The Special Judo Fitness Test (SJFT) has become the test most widely used by coaches and physical trainers for assessment of competitors' judo-specific physical aptitude and training programme prescription. The aim of this study was to investigate the relationship between the SJFT performance indices and both maximal aerobic power and the level of blood lactate concentrations in female judo ath...

OBJECTIVE To review the current evidence for the epidemiology of pediatric injuries in martial arts. DATA SOURCES The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. MAIN RESULTS In g...

This study aimed to analyze neuromuscular variables (vertical jump and torque in external/internal shoulder rotation) in advanced and novice judo athletes, and to identify which neuromuscular variables allow for discrimination between them. Thirty male judo athletes participated in this study: 19 novice and 11 advanced athletes. The judo athletes performed the external/internal shoulder rotatio...

This study aimed to evaluate the viability to use Uchi-komi (UK) in the evaluation of the judo endurance performance and using lactate threshold the analysis of the blood lactate ([Lac]) and heart rate (HR) determined through a lactate minimum test. The subjects were a group of 6 male, volunteer judokas, from 25.17 ± 5.76 years old, weight 84.50 ± 23.78 kg and height 1.78 ± 0.10 m, competitors ...

Judo is one of the most popular martial arts in the world. Researchers reported a higher risk of injuries during training rather than the time of competition. So, the safe and effective training methods should be considered. As development and application of injury prevention approaches and athletic performance enhancement is necessary, the purpose of this study was to investigate the effect of...

The present study had as objectives (1) to compare the morphological and functional characteristics of the male judo players of the Brazilian Team A (n=7) with the judo players of Teams B and C (reserves; n=15), 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,...

Numberless research articles in sports sciences are aimed to validate evaluation tests of physical capacity that are specific for the reality of the sportive activities1-5, thus stimulating and monitoring the training effectiveness6. Within this perspective, there are few specific tests for judo7. The fact that judo is a complex modality with several body movements and metabolic interactions, m...

A study by Rowe et al. reported a winning bias for judo athletes wearing a blue outfit relative to those wearing a white one during the 2004 Olympics. It was suggested that blue is associated with a higher likelihood of winning through differential effects of colour on opponent visibility and/or an intimidating effect on the opponent. However, we argue that there is no colour effect on winning ...

The authors compared ACTN3 R577X genotype and allele frequencies in the majority of all-time-best Spanish judo male athletes (n = 108) and 343 ethnically matched nonathletic men. No between-groups differences were found in allele (P = .077) or genotype distributions (P = .178). Thus, the R577X polymorphism was not significantly associated with the status of being an elite judo athlete, at least...

Taekwondo and judo competitions are divided into weight categories. Many athletes reduce their body mass a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast body mass reduction, athletes use a number of nutritional strategies, including choline supplementation. The goal of this study was to identify the effects of choline supplementat...
