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...

The aim of the present study was to evaluate the influence of the Ramadan intermittent fast (RIF) on aerobic and anaerobic exercise performance in elite judo athletes (Judokas) maintaining their usual training loads. Physical performance tests (squat jump [SJ]), countermovement jump [CMJ], 30-second repeated jump, 30-m sprint, and the multistage fitness test) and fatigue scores were measured in...

The desirability of testing the efficiency of any type of "bodybuilding" program has been commented upon and a method of determining the effect of such a program upon an individual's fitness has been described.5 However, such programs usually include large numbers of individuals, and the separate testing of each one at relatively frequent intervals is so time-consuming as to be impractical; in ...

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...

Firstly, we would like to congratulate the authors of the article “Training monitoring in judo: comparison between the load intensity planned by the coach and the intensity perceived by the athlete”1 on their initiative to investigate a theme this relevant to the training load control. Additionally, we should state that the conclusion is at first surprising: “...although the training program ha...

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without...

BACKGROUND Sports that require the constant use of an upper limb demand the maximum kinetic chain efficiency in this segment. Immaturity of the musculoskeletal system, followed by failure in motor skills can expose adolescents to major reports of pain complaints, particularly for the shoulder. OBJECTIVE To evaluate the prevalence of shoulder pain in adolescent athletes and identify possible f...

The purpose of this article was to review a series of studies (n = 18) on psychological preparation of competitive judokas. These studies were grouped according to the type of study performed - observational, experimental, and case studies. In addition, five psychological categories were identified: (a) imagery, (b) motivation, (c) stress, anxiety, and mood states, (d) eating attitudes and weig...
