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.
