DISCUSSÃO NA SCIENCE SOBRE BENEFÍCIOS DAS ARTES MARCIAIS PARA CRIANÇAS
Interventions Shown to Aid Executive Function Development in Children 4 to 12 Years Old Science 333, 959 (2011);
Adele Diamond1* and Kathleen Lee1
To be successful takes creativity, flexibility, self-control, and discipline. Central to all those are executive functions, including mentally playing with ideas, giving a considered rather than animpulsive response, and staying focused. Diverse activities have been shown to improve children’s executive functions: computerized training, noncomputerized games, aerobics, martial arts, yoga,mindfulness, and school curricula. All successful programs involve repeated practice and progressively increase the challenge to executive functions. Children with worse executive functions benefit most from these activities; thus, early executive-function training may avert widening
achievement gaps later. To improve executive functions, focusing narrowly on them may not be as effective as also addressing emotional and social development (as do curricula that improve executive functions) and physical development (shown by positive effects of aerobics, martial arts, and yoga).

The social-psychological outcomes of martial arts practise among youth: A review
Jikkemien Vertonghen and Marc Theeboom Vrije Universiteit Brussel, Belgium

Abstract
Martial arts involvement among the youth has been described in controversial terms. Studies regarding the effects of martial arts practise on youth show contrasting images. While some refer to enhanced personal and social opportunities for those that participate, others warn against increased levels of aggressiveness and antisocial behavior among its participants. The aim of the present review is to provide, firstly, an overview of the major findings of studies concerning the social-psychological outcomes of martial arts practise. Secondly, the limitations of those studies are discussed. From more than 350 papers, collected during a two-year lasting literature study, 27 papers met all criteria to be included in this study. This review revealed that even though a considerable amount of research on socialpsychological outcomes of martial arts practise has been conducted over the years, to date, it has not brought clarity in the
existing duality regarding the possible effects of martial arts involvement. It is proposed that a better understanding can be provided if specific influential factors are taken into account in future research (i.e., participants’ characteristics, type of guidance, social context and structural qualities of the sport)

JUDO TRAINING IS AN INTERMITTENT METABOLICALLY DEMANDING ACTIVITY THAT HAS HISTORICALLY BEEN CONNECTED TO PHYSICAL EDUCATION AND DEVELOPMENT. THE HEALTH IMPACT OF PRACTICING THIS OLYMPIC SPORT AND MARTIAL ART HIGHLIGHTS THE BENEFITS OF COMBAT SPORTS FOR CHILDREN AND ADOLESCENTS. VARIOUS PHYSIOLOGICAL IMPROVEMENTS, INCLUDING THOSE IN THE AREAS OF BODY COMPOSITION, STRENGTH, AND ENDURANCE, AS WELL AS ENHANCED COGNITIVE PERFORMANCE AND LIFE SATISFACTION HAVE SHOWN TO RESULT FROM PARTICIPATION IN JUDO BY YOUNG PEOPLE.

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.
