IJF apresenta simulação do sistema de classificação olímpica

http://217.79.182.227/www.judo-world.net/_ranking/tta_qualification.php?nation_field=&action=Show

Para não precisar das vagas continentais, os atletas estariam nos Jogos Olímpicos com 224 a 280 pontos e as atletas precisariam de 290 a 428 pontos, dependendo da categoria. Portanto, caso essa média de pontos seja mantida (o que deve acontecer) e a menos que haja um outro atleta do mesmo país melhor posicionado, um título de Grand Slam e um de World Cup no ano final de classificação será suficiente para participar dos Jogos Olímpicos na maior parte das categorias.

Mais um artigo sobre suplementação e processo antioxidante no judô

Abstract

The purpose of this randomized study was to measure the influence of 6 weeks of LCPUFA (600 mg EPA and 400 mg DHA per day) supplementation alone or in association with 30 mg vitamin E, 60 mg vitamin C and 6 mg β-carotene on resting and exercise-induced lipid peroxidation in judoists (n = 36). Blood samples were collected at rest before (T (1)) and after the supplementation period, in preexercise (T (2)) and postexercise (T (3)) conditions, for analysis of α-tocopherol, retinol, lag phase (Lp) before free radical-induced oxidation, maximum rate of oxidation (R (max)) during the propagating chain reaction, maximum amount of conjugated dienes (CD(max)) accumulated after the propagation phase, and nitric oxide, malondialdehyde and lipoperoxide (POOL) concentrations. Dietary data were collected using a 7-day diet record. There were no significant differences among treatment groups with respect to habitual intakes of energy from fat, carbohydrate, or protein. At T (1), there were no significant differences among treatment groups with respect to lipid peroxidation, lag phase, and levels of α-tocopherol or retinol. The consumption of an n-3 LC PUFA supplement increased oxidative stress at rest and did not attenuate the exercise-induced oxidative stress. The addition of antioxidants did not prevent the formation of oxidation products at rest. On the contrary, it seems that the combination of antioxidants added to the n-3 LCPUFA supplement led to a decrease in, CD(max), R (max), and POOL and MDA concentrations after a judo training session.

Fim das equipes competitivas de judô

Em menos de um mês, três equipes de judô "fecharam as portas": GR Barueri, AD São Caetano e FTC. Algo realmente preocupante, considerando que estamos a um ano e meio dos Jogos Olímpicos e a dois e meio de um Campeonato Mundial em SP. Duas delas eram de prefeituras na região metropolitana de SP e possuíam atletas na seleção brasileira ou na seletiva que acontecerá neste final de semana. Adicionalmente, essas três equipes disputaram o GP Nacional, sendo que uma foi campeã e a outra quarto lugar.
Será esse o legado dos megaeventos no país? Para refletir...

Perfil fisiológico de atletas de judô de elite

Abstract
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 non-elite 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 and females in the general population are also seen in judo athletes when analysing anaerobic power and capacity, aerobic power, and maximal strength and power. However, further research is needed concerning the differences among the seven weight categories in which judo athletes compete.
