A diretoria do Flamengo confirmou que não renovará os contratos de 28 atletas que compõem a ginastica e o judô profissionais do clube. De acordo com o planejamento feito pelo vice-presidente de esportes olímpicos, Alexandre Póvoa, em conjunto com o diretor executivo da pasta, Marcelo Vido, o Rubro-Negro vai manter as duas modalidades apenas com categorias de base e escolinhas,como aconteceu com a natação. A diretoria afirma que o custo das duas equipes juntas chegava a R$ 2 milhões por ano e que não teve sucesso ao pedir ajuda a duas esferas do governo e ao Comitê Olímpico Brasileiro (COB).

- Infelizmente nós estamos sendo obrigados a suspender temporariamente as equipes de ginástica artística e judô. Fomos conversar com a prefeitura, com o governador e com o COB para tentar explicar a situação e tentar uma ponte para 2013. Na prefeitura houve uma discussão mais em torno do futebol. No governo, houve uma ajuda da Loterj para o basquete. No COB só nos foi oferecido apoio logístico, com centro de treinamento, ajuda em construções para o remo e coisas do tipo. Mas nenhum dinheiro vivo nos foi oferecido - disse Póvoa, em entrevista coletiva na sede da Gávea, na manhã desta terça-feira.

Desta forma, o Flamengo deixa de patrocinar oito atletas da ginásticas, dentre eles o bicampeão mundial do solo, Diego Hypolito, além de Jade Barbosa e Daniele Hypolito. No judô, 19 lutadores, incluindo João Gabriel Schlittler, Breno Viola e Nacif Elias, perdem as ajudas de custo que recebiam. A técnica da seleção brasileira feminina, Rosicléia Campos, também ficou sem o emprego. O único caso pendente é o da atleta olímpica Érika Miranda. O Fla ainda estuda se mantém o contrato, válido até maio, antecipa a  rescisão. No ano passado, a equipe feminina de judô conquistou o título inédito do Grand Prix Interclubes.

O clube, no entanto, assumiu o compromisso de quitar os três meses de salários atrasados. Aqueles que recebiam vencimentos mais baixos deverão receber as quantias em dois ou até três meses, enquanto os donos dos maiores salários poderão esperar até 18 meses para embolsarem as quantias a que têm direito.

Dos esportes olímpicos, apenas o remo, por exigência estatutária, o pólo aquático e o nado sincronizado, com baixo custo, e o basquete, com patrocínio próprio, serão mantidos. Mesmo admitindo que o time, líder da atual edição do NBB, ainda está em déficit, Póvoa garantiu que não há risco do fim da equipe e ressaltou que se trata do segundo esporte do clube atualmente.

No fim do ano passado, após a vitória de Eduardo Bandeira de Mello na eleição presidencial do clube, a nova diretoria já havia anunciado o fim da equipe de natação, que tinha como expoente o campeão olímpico e bicampeão mundial Cesar Cielo, além de Nicholas Santos, Leonardo de Deus, Thales Cerdeira e Henrique Barbosa, antigos membros do P.RO.16. Segundo Póvoa, o plantel gerava um custo de R$ 5 milhões anuais para o Flamengo.

Incêndio em ginásio do Fla gera prejuízo de cerca de R$ 800 mil (Foto: Fernando Azevedo / Fla Imagem)

Em novembro de 2012, o ginásio Cláudio Coutinho, onde a equipe de ginástica treinava, foidestruído por um incêndio. Desde então, os ginastas vinham utilizando as instalações do Velódromo, que, entretanto, fechou as portas no último dia 8 de fevereiro. O local será demolido para a construção de um novo, já que não atende aos requisitos necessários para receber as Olimpíadas de 2016. Sem o Velódromo, os atletas do masculino passaram a treinar em São Paulo, e do feminino, em Três Rios, interior do Rio de Janeiro.

Esportes olímpicos do Fla entre altos e baixos nos últimos anos
Os esportes olímpicos do Flamengo passaram por outras crises na última década. Em 2009, a gestão de Márcio Braga anunciou não ter verbas para renovar os contratos dos esportes olímpicos, exceto o remo e o basquete - o primeiro é uma obrigação assegurada pelo estatuto do clube, e o segundo tinha patrocinador próprio. O desgaste foi enorme com os principais nomes da ginástica, mas um acordo com a prefeitura de Niterói, no estado do Rio de Janeiro, apareceu como salvação. A ajuda de R$ 80 mil mensais, no entanto, nunca foi dada, já que problemas burocráticos emperraram o acordo. O grupo ficou quase um ano sem receber salários, apenas utilizando a estrutura física disponível.

rendeu frutos em 2009 (Foto: Ag. Estado)

Patricia Amorim, então vice-presidente de esportes olímpicos, foi substituída por João Henrique Areias no cargo, e os problemas no basquete foram evidenciados. O novo dirigente montou um projeto para oferecer a equipe a uma cidade do estado do Rio de Janeiro e vender cotas de patrocínio a pessoas físicas e jurídicas do município, com o objetivo de arrecadar R$ 150 mil por mês. Areias conseguiu um patrocínio, colocou os salários em dia e fechou acordo com a Arena da Barra para mandar os jogos da final da primeira edição do Novo Basquete Brasil (NBB). O time sagrou-se campeão  mas, no dia seguinte ao título, Areias desligou-se do cargo.

A eleição de Patricia como presidente do Flamengo, empossada em janeiro de 2010, fez osinvestimentos em esportes olímpicos crescerem. A mandatária negociou dívidas com salários da ginástica, fechou novos patrocínios para o basquete e investiu na natação, contratando Cesar Cielo como carro-chefe de uma equipe que contava ainda com Joanna Maranhão, Nicholas Santos, entre outros.

Desde a eleição de Bandeira de Mello, porém, os cortes começaram. Novo vice-presidente de esportes olímpicos do Flamengo, Alexandre Póvoa anunciou que os contratos que venciam em 31 de dezembro de 2012 não seriam renovados, mas garantiu que os salários atrasados – segundo ele, dos três meses anteriores -, seriam quitados pela nova gestão. Em janeiro, foi a vez do lutador de MMA José Aldo parar de usar o escudo do clube. O campeão peso-pena do UFC, porém, não descarta retomar o acordo no futuro.

Abstract

BACKGROUND:

Several studies report martial arts as a good model for investigating neuroendocrine responses to competitive fighting. However, little is known on the metabolic responses elicited by elite athletes during fighting. In particular, the metabolic picture in elite athletes of martial arts is little known.

AIM:

In the present study, our aim was to investigate the acute effects of a session of karate practice on the glucose-insulin system.

SUBJECTS AND METHODS:

Ten healthy individuals (6M/4F; BMI: 22.1 ± 0.7 kg/m(2); 21.9 ± 1.1 years, mean ± SE) who practice karate in national or international competitions were enrolled. All participants completed two experimental trials in a randomised-crossover fashion. A basal blood sample was collected from each athlete to assess plasma glucose, insulin, cortisol, testosterone and catecholamines, before karate training session. In two separate days, another blood sample was collected from each participants after 3 min of real fighting (kumite) and 3 min of ritualized simulation of combat (kata).

RESULTS:

In both trials, plasma glucose resulted to be higher at the end the of performance compared to the basal (p < 0.001 after kumite and p < 0.02 after kata). In contrast, insulin was similar in the basal and after physical activity in the two trials. Catecholamines were higher after kata and kumite sessions with respect to the basal values (p < 0.04) and, in particular, epinephrine post-kumite values were much greater than those measured after kata.

CONCLUSIONS:

Our results indicate that unlike performances of karate (kumite and kata) elicit different plasma glucose increases. In particular, we found that glucose and epinephrine concentrations increased more after kumite than after kata.

Abstract

ABSTRACT: The purpose of this study was to characterize the magnitude of acute weight gain (AWG) and dehydration in mixed martial arts (MMA) fighters prior to competition. Urinary measures of hydration status and body mass were determined ∼24 h prior and then again ∼2 h prior to competition in 40 MMA fighters (Mean ± SE, age: 25.2 ± 0.65 yr, height: 1.77 ± 0.01 m, body mass: 75.8 ± 1.5 kg). AWG was defined as the amount of body weight the fighters gained in the ∼22 h period between the official weigh-in and the actual competition. On average, the MMA fighters gained 3.40 ± 2.2 kg or 4.4% of their body weight in the ∼22 h period prior to competition. Urine specific gravity significantly decreased (P < 0.001) from 1.028 ± 0.001 to 1.020 ± 0.001 during the ∼22 h rehydration period. Results demonstrated that 39% of the MMA fighters presented with a Usg of greater than 1.021 immediately prior to competition indicating significant or serious dehydration. MMA fighters undergo significant dehydration and fluctuations in body mass (4.4% avg.) in the 24 h period prior to competition. Urinary measures of hydration status indicate that a significant proportion of MMA fighters are not successfully rehydrating prior to competition and subsequently are competing in a dehydrated state. Weight management guidelines to prevent acute dehydration in MMA fighters are warranted to prevent unnecessary adverse health events secondary to dehydration.

Abstract

The timing of visual information pick-up for visual anticipation was examined by comparing the capability of multiple skill groups, expert and near-expert karate athletes and novices, to block attacks using an in situ temporal occlusion paradigm. Participants stood facing a karate opponent and then attempted to block attacks (kicks and punches), whilst their vision of attacks was occluded: (a) prior to onset of opponent motion (O1), (b) after preparatory head movement (O2), and (c) after initiation of the attacking motion (O3). A no occlusion control condition provided complete vision of attacks (O4). Results revealed that expert anticipation was not significantly different to that of near-experts at O1, but was significantly different to the other group across O2-O4. Expert anticipation, however, was significantly above chance across all occlusion conditions, but near-experts performed above chance at O3 and O4, whilst novices were better than chance at O4. Unexpectedly, unique evidence was found that expert anticipation could be differentiated from near-expert anticipation in the earliest occlusion condition, where it was found that only experts were capable of using visual information from a static opponent to anticipate and block attacks above chance. The findings further understanding of expert visual anticipation to guide motor skills beyond existing expert-novice comparisons.

Abstract

This study assessed the effects of dietary sodium citrate supplementation during a 16 h recovery from 5% rapid body mass loss (RBML) on physiological functions, affective state, and performance in trained wrestlers. Sixteen wrestlers performed an upper body intermittent sprint performance (UBISP) test under three conditions: before RBML, after RBML, and after a 16 h recovery from RBML. During recovery, the subjects ate a prescribed diet supplemented with sodium citrate (600 mg·kg(-1); CIT group, N = 8) or placebo (PLC group, N = 8) and drank water ad libitum. RBML reduced (p < 0.05) UBISP mean power and increased urine specific gravity (USG). Reduction in mean power was associated with changes in plasma volume (PV) (r = 0.649, p = 0.006) and USG (r = -0.553, p = 0.026). During the 16 h recovery, increases in body mass (BM) and PV were greater (p < 0.05) in the CIT group than in the PLC group. BM gain was associated with water retention in the CIT group (r = 0.899, p = 0.002) but not in the PLC group (r = 0.335, p = 0.417). Blood pH, HCO(3)(-) concentration, and base excess increased (p < 0.05) only in the CIT group. Changes in UBISP, general negative affect, and general positive affect did not differ in the two groups. In conclusion, ingestion of sodium citrate increases blood buffering capacity and PV and stimulates BM regain during a 16 h recovery from RBML in trained wrestlers. However, sodium citrate does not improve UBISP nor does it have an impact on the affective state.

Abstract

Abstract The aim of this study was to test the effect that changing targets during a simple long lunge attack in fencing exerts on the temporal parameters of the reaction response, the execution speed, and the precision and the coordination of the movement pattern. Thirty fencers with more than 10 years of experience participated in this study. Two force platforms were used to record the horizontal components of the reaction forces and thereby to determine the beginning of the movement. A three-dimensional (3D) system recorded the spatial positions of the 9 markers situated on the fencer plus the epee, while a moving target was projected on a screen, enabling the control of the target change. The results indicated that when a target change is provoked the reaction time (RT), movement time (MT), and the time used in the acceleration phase of the centre of mass (CM) increases significantly with respect to the attack executed with a straight thrust. The speed and horizontal distance reached by the CM at the end of the acceleration phase (V(X(CM)) and S(X(CM)), respectively) significantly decreased, while the errors increased. However, the temporal sequence of the movement pattern did not appreciably change.

RESUMO
O presente estudo teve como objetivo avaliar o comportamento da frequência cardíaca (FC) e sua relação com a percepção subjetiva de esforço (PSE) em atletas de Jiu-Jitsu Brasileiro (JJB) com idade de 27±6,24 anos, 85,6±16,95 kg, 1,76±0,06 m e IMC 28 ± 4,33 kg/m². O protocolo experimental consistiu da simulação de um combate com utilização de tempo oficial (10 minutos) independente de ocorrer ou não a finalização do adversário. A FC foi aferida pré (113,4±13,2 bpm), durante todo combate, nos minutos 2,5 (165,1±11,9 bpm), 5 (170,1±15,9 bpm), 7,5 (170,1±13,9 bpm) e 10 (173,1±10,4 bpm) e pós, nos minutos 1 (139,8±13,0 bpm), 2 (132,4±10,6 bpm) e 3 (127,1±12,1 bpm), assim como a PSE (5,0±1,0) ao final da luta. De acordo com os resultados foi possível verificar que os lutadores mantiveram a frequência cardíaca elevada durante toda a luta, correspondendo a uma alta intensidade de esforço (91,6±5,5 %), assim como a PSE, que apresentou classificação próxima à PESADA. Deste modo, concluímos que a utilização da escala de Borg foi capaz de identificar a intensidade de esforço durante

CORRELAÇÃO ENTRE POTÊNCIA DE MEMBROS INFERIORES, ÍNDICE DE FADIGA E ÍNDICE ELÁSTICO EM TESTES DE SALTOS VERTICAIS EM LUTADORES MILITARES DE TAEKWONDO
Antônio Márcio dos Santos Valente1,
Marcos Túlio Batista2,
Liliam Fernandes de Oliveira3


RESUMO
A prática do taekwondo envolve saídas explosivas e uma grande quantidade de saltos com mudanças de direção e giros rápidos. Estas características favorecem o aparecimento da fadiga, uma variável presente em diversas situações de luta. Testes físicos com saltos verticais têm sido aplicados para quantificação do desempenho e estimativa da capacidade atlética em geral, como a potência de membros inferiores, a resistência à fadiga e a contribuição do componente elástico do músculo. O objetivo deste trabalho foi analisar o índice elástico (IE), o índice de fadiga (IF), o pico de potência (PP) e a potência média (PM) durante o desempenho de saltos verticais de atletas de taekwondo baseados em parâmetros de resistência muscular de membros inferiores (MMII) em atletas desta modalidade. Sete atletas de taekwondo masculino realizaram três tipos de saltos em um tapete de contato: com contramovimento e sem utilização dos membros superiores (CMJ), salto partindo da posição estática com 90º de flexão de joelho (SJ 90º) e 4 séries de 15s de saltos intermitentes. As variáveis estudadas foram: o pico de potência (PP), a potência média (PM), o índice de armazenamento de energia elástica (IE) e o índice de fadiga (IF). Os resultados registraram valor de IE = 7,59 ± 2,07 cm e IF = 81 ± 0,12%. O valor do PP = 25,79 ± 2,26 watts/kg está compatível com os achados em estudos envolvendo atletas de outras modalidades já a PM = 23,22 ± 1,98 watts/kg, manteve-se relativamente acima, indicando a necessidade de um melhor controle no esforço máximo durante o teste. As análises indicam que não há correlação entre a estimativa dos valores (IE) e (IF) e que média da altura dos saltos realizados nas 4 séries de 15s parece estar relacionada com a qualidade de força muscular devido à correlação positiva e significativa com o SJ. Sugere-se atenção na interpretação dos resultados, pois a produção da PM pode ser influenciada pela eficiência mecânica do movimento em esforço máximo e pelo efeito motivacional do atleta na realização do teste.

FILA cria comissão científica

PRESS RELEASE
February 20, 2013


From the FILA Bureau Meeting held in Phuket (THA) on 15-16 February 2013: Approval was given for the establishment of a Scientific Department within FILA and named David Curby (USA), Boris Podlivaev (RUS), Harold Tünnemann (GER), Ioannis Barbas (GRE), Bahman Mirzaei (IRI) as members.


The impetus for this major addition has been the work of the International Network of Wrestling Researchers (INWR). During the past five years, this organization has gathered a large network of over 250 scholars and wrestling professionals from 58 FILA countries. The INWR has organized scientific meetings at the past two world championships, and the publishing of a scientific journal-the International Journal of Wrestling Science. The INWR initiated the proposal for a Scientific Department to FILA two in 2011. Our intentions are work for FILA and support the new department in the following areas:

Promotion and Support of Needed Wrestling Research
* Conduct research requested by FILA to answer important questions.
* Organize research activities at major wrestling competitions and training centers.
* Form collaborative arrangements that will provide the Department with increased access to expertise and other research resources.
* Identify wrestling researchers and scientists at an international level.
* Build a communication network so that wrestling researchers may communicate and share ideas.
* Support a database of wrestling-related research articles.

Distribution of Wrestling Scientific Knowledge
* Organize wrestling scientific congresses, seminars and workshops.
* Publish a wrestling scientific journal.
* Provide a wrestling scientific portal and discussion forum to enable communication between wrestling scientists, coaches and athletes.
* Support wrestling-related educational activities in collaboration with academic institutions and universities (e.g. advanced degrees).

Scientific Support
* Provide scientific information for FILA Bureau and the other FILA Departments.
* Provide scientific information for National Wrestling Federations.
* Develop the curricula of training and certification programs for all Federations to use with the various level of coaches-basic to advanced degrees.
* Complete other relevant tasks as assigned by the FILA Bureau.

The work of this department in the year 2013, will have the following objectives: 1) organize the new Scientific Department and provide immediate support to the efforts to keep our sport in the Olympic Games; 2) continue the publication and dissemination of our journal in March and September; 3) produce the curriculum for the basic wrestling coach certification for use by all federations (with advanced programs to follow) and 4) organize a combined Medical and Scientific Congress to be held in conjunction with the Budapest World Championships. We remain at the disposal of FILA and will take the steps that are necessary to bring the FILA Scientific Department to the service of wrestling.

Abstract

The purpose of the research was to compare muscle torque of elite combat groups. Twelve taekwondo WTF athletes, twelvetaekwondo ITF athletes and nine boxers participated in the study. Measurements of muscle torques were done under static conditions on a special stand which belonged to the Department of Biomechanics. The sum of muscle torque of lower right and left extremities of relative values was significantly higher for taekwondo WTF athletes than for boxers (16%, p < 0.001 for right and 10%, p < 0.05 for left extremities) and taekwondo ITF (10%, p < 0.05 for right and 8% for left extremities). TaekwondoITF athletes attained significantly higher absolute muscle torque values than boxers for elbow flexors (20%, p < 0.05 for right and 11% for left extremities) and extensors (14% for right and 18%, p < 0.05 for left extremities) and shoulder flexors (10% for right and 12%, p < 0.05 for left extremities) and extensors (11% for right and 1% for left extremities). Taekwondo WTF andtaekwondo ITF athletes obtained significantly different relative values of muscle torque of the hip flexors (16%, p < 0.05) and extensors (11%, p < 0.05) of the right extremities.

Abstract

Hill and Barton (2005) showed that fighters in tae kwon do, boxing, and wrestling who wore red jerseys during the 2004 Olympic Games won more often than those wearing blue jerseys. Regarding these results, this study investigated the effects of jersey color during a combat situation on fighters' physical parameters of strength and heart rate. An artificial, experimental combat situation was created in which the color of sport attire was assigned randomly. Fourteen pairs of male athletes matched for weight, height, and age had to fight each other: once in a red jersey and once in a blue. Heart rate (before, during, and after the fight) and strength (before the fight) were tested wearing the blue and the red jerseys. Participants wearing red jerseys had significantly higher heart rates and significantly higher pre-contest values on the strength test. Results showed that participants' body functions are influenced by wearing red equipment.

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)
