Feliz 2013!!!

Escrevo para agradecer aos que me deram a oportunidade de praticar judô, discutir ideias, escrever e pensar nos projetos para os próximos anos.
2012 foi um ano ao mesmo tempo muito duro em alguns aspectos e de muito sucesso em muitos outros.
Tinha planejado escrever um texto longo, agradecendo um por um, mas o cansaço e a preguiça não permitiram. E isso é bom, porque tenho descansado bem nesses dias de recesso : )
Espero que todos vocês possam aproveitar 2013.
Feliz ano novo.

Sport science relevance and application: Perceptions of UK coaches.

a Edinburgh Napier University, SLSSS , Edinburgh , United Kingdom.

Abstract

Abstract While sport science can have significant and positive impact on coaches and athletes, there is still a general consensus that the transfer of sport science knowledge to coaching is poor. Given this apparent dilemma, this study investigated the perceptions of sport science from coaches across four different sports (football, rugby league, curling and judo) across three different levels (elite, developmental and novice). Specifically, 58 coaches (19 football; 21 rugby league; 9 curling; 9 judo) drawn evenly from novice, developmental and elite groups agreed to take part and were interviewed. Three key features emerged from the analysis 1) Practical application and relevance 2) Integration and access, 3) Language. In short, there was significant variability in the extent to which sport science was considered relevant and to whom, although interestingly this was not strongly related to coaching level. This inconsistency of understanding was a barrier to sport science engagement in some instances, as was the challenge of operationalising information for specific contexts. Furthermore, availability of opportunities and resources were often left to chance, while overuse of jargon and inability for research and practitioners to consider sport specific needs were also considered barriers to engagement. Implications for research and practice are discussed.

História do judô feminino na Bélgica

The Early Development of Women's Judo in Belgium from the Liberation to the late 1950s: Emancipation, Sport and Self-defence
Haimo Groenena*

Abstract

This cultural and comparative history examines the early development of women's judo in Belgium through gender and sport, and within the different communities and federations. Born in the late 1940s, women's judo in Belgium remained both a minority sport and under the domination of men during the 1950s. Circumscribed by dominant gender norms imposing a traditional representation of women, women's judo was, nevertheless, also a means for emancipation. It turned to recreational sport and self-defence in the Flemish part of the country, as well as temporarily to competitions in one part of the French-speaking community. The latter was generally a more conducive space to recognition and emancipation of female judokas. These similarities and differences lay in the articulation of several factors: cultural specificities of judo, influence of French and Japanese models, conceptions of pioneers and federal leaders, sociocultural characteristics of the linguistic communities, importance of Catholicism and emancipation of women.
Les débuts du judo féminin en Belgique de la Libération aux années 1950: émancipation, sport et self-défense
À travers une histoire culturelle et comparée, cette contribution questionne les débuts du judo belge féminin sous l'angle du genre et de la dimension sportive, ainsi qu'au regard des différentes communautés et fédrations. Né à la fin des années 1940, le judo belge féminin reste, durant la décennie suivante, minoritaire et sous tutelle masculine. Circonscrit par des normes de genre dominantes imposant une représentation traditionnelle de la femme, le judo féminin constitue pourtant également un moyen d'émancipation. Il s'oriente alors, en Flandre, vers la self-défense et le loisir sportif, mais aussi temporairement vers des compétitions dans la communauté francophone, plus propice à la valorisation et à l'émancipation des judokas féminins. Ces points communs et différences tiennent à l'articulation de plusieurs facteurs: les spécificités culturelles du judo, l'influence de modèles français et japonais, les conceptions des pionniers et responsables fédéraux, les caractéristiques socioculturelles des communautés linguistiques, le poids du catholicisme et l'émancipation des femmes.
El desarrollo inicial del judo femenino en Bélgica desde la Liberación hasta finales de los años 50: emancipación, deporte y autodefensa
Esta historia cultural y comparativa analiza el desarrollo inicial del judo femenino en Bélgica desde la perspectiva del género y el deporte, y en el marco de las diversas comunidades y federaciones. Surgido a finales de los años 40, el judo femenino fue un deporte minoritario y controlado por los hombres durante los años 50. El judo femenino estaba constreñido por las normas de género dominantes, que imponían una representación tradicional de las mujeres, pero también era un instrumento de emancipación. Se convirtió en un deporte recreativo y de autodefensa en la parte flamenca del país, mientras que en la parte francófona dio pie durante algún tiempo a competiciones. Éstas últimas constituían generalmente un espacio más propicio para el reconocimiento y la emancipación de las mujeres judokas. Estas similitudes y diferencias derivan de la articulación de varios factores: las especificidades culturales del judo, la influencia de los modelos francés y japonés, las ideas de los pioneros y de los líderes federales, las características socioculturales de las comunidades lingüísticas, la importancia del catolicismo y el grado de emancipación de las mujeres.
Die frühe Entwicklung des Frauen-Judo in Belgien von der Befreiung bis zu en späten 1950er Jahren: Emanzipation, Sport und Selbstverteidigung
Diese kulturelle und vergleichende Geschichte untersucht die frühe Entwicklung des Frauen-Judo in Belgien über Gender und Sport und innerhalb der verschiedenen Gemeinden und Verbände. Geboren in den späten 1940er Jahren blieb Frauen-Judo in Belgien in den 1950er Jahren sowohl eine Randsportart als auch unter der Vorherrschaft der Männer. Beschränkt durch dominante Gender-Normen, die eine traditionelle Darstellung von Frauen aufzwangen, war Frauen-Judo dennoch auch ein Mittel zur Emanzipation. Es wandte sich zum Freizeitsport und zur Selbstverteidigung im flämischen Teil des Landes sowie vorübergehend zu Wettkämpfen in einem Teil der französischsprachigen Gemeinschaft. Letzteres war im Allgemeinen eine förderlichere Rahmenbedingung für die Anerkennung und Emanzipation weiblicher Judoka. Diese Gemeinsamkeiten und Unterschiede hingen von mehreren Faktoren ab: kulturelle Besonderheiten des Judo, Einfluss französischer und japanischer Modelle, Vorstellungen von Pionieren und Führern auf Bundesebene, soziokulturelle Merkmale der Sprachgemeinschaften, Bedeutung des Katholizismus und der Emanzipation der Frauen.

Suplementação com alga e secreção de IgA em atletas de kendo


 2012 Dec 11;11(1):103. [Epub ahead of print]

Chlorella intake attenuates reduced salivary SIgA secretion in kendo training camp participants.

Abstract

ABSTRACT:

BACKGROUND: The green alga Chlorella contains high levels of proteins, vitamins, and minerals. We previously reported that a chlorella-derived multicomponent supplement increased the secretion rate of salivary secretory immunoglobulin A (SIgA) in humans. Here, we investigated whether intake of this chlorella-derived supplement attenuated the reduced salivary SIgA secretion rate during a kendo training camp.

METHODS:

Ten female kendo athletes participated in inter-university 6-day spring and 4-day summer camps. They were randomized into two groups; one took placebo tablets during the spring camp and chlorella tablets during the summer camp, while the other took chlorella tablets during the spring camp and placebo tablets during the summer camp. Subjects took these tablets starting 4 weeks before the camp until post-camp saliva sampling. Salivary SIgA concentrations were measured by ELISA.

RESULTS:

All subjects participated in nearly all training programs, and body-mass changes and subjective physical well-being scores during the camps were comparable between the groups. However, salivary SIgA secretion rate changes were different between these groups. Salivary SIgA secretion rates decreased during the camp in the placebo group (before vs. second, middle, and final day of camp, and after the camp: 146 +/- 89 vs. 87 +/- 56, 70 +/- 45, 94 +/- 58, and 116 +/- 71 mug/min), whereas no such decreases were observed in the chlorella group (121 +/- 53 vs. 113 +/- 68, 98 +/- 69,115 +/- 80, and 128 +/- 59 mug/min).

CONCLUSION:

Our results suggest that a use of a chlorella-derived dietary supplement attenuates reduced salivary SIgA secretion during a training camp for a competitive sport.

Abstract

ABSTRACT: The purpose of this investigation was to describe the physiological profile of elite senior Chinese female wrestlers. Twenty-five elite wrestlers, nationally ranked in the top-3 of their weight class, participated in the study. The subjects included Olympic and world champion medalists. The physiological profile included testing of running maximal oxygen consumption (VO2max), 3,200 m run time, 400 m run time, 30 s Wingate anaerobic power and capacity, shoulder, elbow, knee and trunk isokinetic torque, and one repetition maximums (1 RM) in specified exercises. The major results (mean ± SD) were VO2max: 50.58 ± 3.33 ml kg min; 3,200 m run: 14.1 min ± 0.49 s; 400m run: 1min 11 s ± 4 s; Wingate maximal anaerobic power: 495.21 ± 79.13 W and mean power: 262.97 ± 52.39 W; 1 RM dead lift: 124 ± 19 kg; 1 RM deep squat: 98 ± 11 kg; 1 RM prone rowing: 72 ± 8 kg; 1 RM power clean: 76 ± 12 kg; and 1 RM hold and squat: 109 ± 17 kg. In absolute terms in the majority of measures the heavier weight classes had greater values than the lighter weight classes, but relative to body mass there were few differences in measures between weight classes. In most measures the best value was that of an Olympic and/or world championship medalist. The results indicate female wrestling success is not dependent upon one physiological characteristic, but that a variety of physiological profiles can result in success. This data on elite female wrestlers can be compared to other wrestlers to help determine individual weaknesses or strengths, and to design training programs that result inwrestling success.
