Judô espacial

IMPORTANTE
NASA declara que o amortecimento de quedas é mais eficiente na Lua. Crianças com medo de cair ou com dificuldade no aprendizado dessas técnicas passarão a aprender as técnicas de ukemi do judô nesse local. Astronautas já estão sendo treinados para transmitir as técnicas. Os candidatos brasileiros para o ensino lunar deverão possuir registro profissional.
A NASA também descobriu que os astronautas que simultaneamente apresentam olhos negros e são canhotos preferem o judô como modalidade esportiva. Em missões em que pelo menos dois astronautas gostarem de judô, a agência considera a possibilidade de alterar o tradicional uniforme branco, entregando um uniforme azul para um deles. Dessa forma, além de facilitar o monitoramento das técnicas aplicadas pela dupla, atenderão a regra da FIJ qto à coloração dos judogis. Aqueles que romperem a pegada com as duas mãos serão enviados em uma missão ao Sol.

Abstract

Purpose: The present study aims at investigating the physiological response and technical-tactical parameters in Brazilian jiu-jitsu competition.

Methods: The study included 35 male Brazilian jiu-jitsu athletes (adult category, body mass: 80.2 ± 13.0 kg), graded from white to brown belt, during combats fought at regional level. Twenty-two fights were analyzed in terms of technique and time structure. Blood glucose, lactate and maximal isometric grip strength were determined before and after the fights. The rate of perceived exertion was also assessed after the fight, using the 6-20 Borg scale. The fights were recorded and the following variables were determined: the exertion/pause ratio and subjective intensity of actions, categorized between low and high intensity.

Results: The results indicated that during Brazilian jiu-jitsu fights, the glycolytic pathway is only moderately activated (lactate before: 4.4 (4.0 – 4.6) mmol/L, after: 10.1 (8.0 – 11.3) mmol/L; glucose before: 112.4 ± 22.3 mg/dL, after: 130.5 ± 31.0 mg/dL). The exertion during the fight resulted in significant reductions in handgrip strength (right hand grip before: 45.9 ± 10.3 kgf, after: 40.1 ± 9.5 kgf; left hand grip before: 44.2 ± 11.1 kgf, after: 37.0 ± 10.2 kgf). The athletes rated the fight as hard: 15 (13 – 15). Effort/pause ratio was 6:1, while high-intensity actions lasted approximately 4 s, resulting in a low/high intensity ratio of 6:1.

Conclusions: It is recommended that coaches direct the training loads to simulate the energy demand imposed by the competitive matches, activating moderately the glycolytic pathway. Moreover, the time structure of combats can be used to prescribe both physical and technical-tactical training.

Revendo os clássicos para entender o presente

Saeki (1994) The conflict between Tradition and Modernization in a Sport Organization: A Sociological Study of Issues Surrounding the Organizational Reformation of the all Japan Judo FederationInternational Review for Sociology of Sport,
"The direct reason for the AJSJF to secede from the AJJF was a reaction against the tight control of the AJJF during the 1st International Student Judo Tournament - The Shoriki Cup. As indicated by the name of the tournament, the tournament was held in commemoration of Matsutaro Shoriki, chairman of the Congressional Judo Federation and CEO of one of Japan’s major dailynewspapers, The Daily Yomiuri, as well as Nippon Television, a national television network. As chairman of a supporter’s association, Shoriki collected a significant donation which went to the construction of the new Kodokan building as part of the 70th anniversary of the Kodokan. To show its appreciation for Shoriki’s efforts, the Kodokan granted him an honorary 9th degree. However, it is said that Shoriki expected instead a 10th degree and since this incident, became critical of the Kodokan (Kudo 1972). Later, Shoriki petitioned Congress to create a new mecca for the martial arts and his efforts resulted in the creation of the Budokan in 1964 (Oimatsu 1970). It was due to these reasons that the judo events during the 1964 Summer Olympics were held at the Budokan and not the Kodokan. Behind the conflict of the AJJF and AJSJF lay the conflict between Shoriki and the Kodokan." (p.308-309).

AJJF = All Japan Judo Federation
AJSJF = All Japan Student Judo Federation


"A razão direta para a AJSJF separar-se da AJJF foi um reação contra o controle rígido da AJJF durante o 1o Torneio de Judô Estudantil Internacional - A Copa Shoriki. Como indicado pelo nome do torneio, o torneio foi realizado em comemoração a Matsutaro Shoriki, presidente Congressional Judo Federation e CEO de um dos principais jornais diários do Japão, The Daily Yomiuri, como também da Televisão Nippon, uma rede de televisão nacional. Como presidente de uma associação de patrocinadores, Shoriki coletou uma significante doação que resultou na construção do novo prédio da Kodokan como parte do 70o aniversário da Kodokan. Para mostrar seu apreço pelos esforços de Shoriki, a Kodokan o concedeu o 9o dan honorário. No entanto, é dito que Shoriki esperava o 10th dan e desde esse incidente, se tornou crítico da Kodokan (Kudo 1972). Depois, Shoriki solicitou ao Congresso para criar uma nova meca para as artes marciais e seus esforços resultaram na criação da Budokan em 1964 (Oimatsu 1970). Foi devido a essas razões que os eventos de judô durante os Jogos Olímpicos de verão de 1964 foram realizados na Budokan e não na Kodokan. Atrás do conflito da AJJF e AJSJF está o conflito entre Shoriki e a Kodokan" (p.308-309).

Abstract

Abstract The ergogenic effect of caffeine on sports performance focuses predominantly on endurance sports (Doherty & Smith, 2004 ) with little research on intermittent high intensity sports. This study aimed to explore the effect of caffeine ingestion on skill maintenance following fencingsimulated exercise. Eleven competitive fencers participated (four female; seven male; age 33 ± 6.5 years). Following a maximal test to exhaustion, fencers completed two trials assessing accuracy and reaction times (Stroop test) before and after a fatiguing protocol designed to simulate the demands of a fencing competition. Skill testing involved 30 lunges to hit a target. 500 ml placebo or 3 mg · kg(-1) caffeine supplemented drink was administered after the initial reaction and skill tests in a single-blind crossover design. The fatiguing protocol involved simulating six fights with 6-minute rests between each. Fencers rated their perceived exertion (arm, legs, overall) using the Borg scale. There was no overall effect of caffeine on total skill score (P = 0.40), however there was a tendency for fewer misses with caffeine (P = 0.10). Caffeine had no effect on the Stroop Test. Caffeine produced significantly lower perceived fatigue for overall (P < 0.01). These results provide some support for caffeine producing maintenance of skill and reducing perceived fatigue during fencing.
