Esses são os árbitros que todos atletas desejam

Quem acessou a página do Mundial de Kendô no Brasil já deve ter visto, mas vale a recomendação.
Além da precisão dos árbitros é interessante ver a análise técnico-tático, quanto à importância da variação.

Treinamento da Seleção Japonesa de Judô

Veja a lista de vídeos no youtube que recebi do Alexandre Lee, mostrando os treinos dos japoneses. Algumas inovações interessantes, algumas práticas já consolidadas na modalidade, mas algo verdadeiramente interessante para discutir o processo de treino físico para a modalidade.
Para quem não domina a língua, vale adiantar o trecho das entrevistas e ver os exercícios.

Ah! notem que algumas cargas são muito leves para quem está executando. Montaram apenas para filmar, a ideia é esconder a carga verdadeira ou eles treinam assim mesmo?

Para pessoas de 10-13 anos, jogar boxe no Wii equivale a caminhar a 5,7 km/h

Artigo interessante e estudo de fácil execução, porém com boas perspectivas de aplicação.
Também é interessante o tópico inicial do periódico, que propõe uma breve explicação sobre o que é conhecido sobre o assunto e o que esse estudo adiciona ao conhecimento.

Playing active video games increases energy expenditure in children.

OBJECTIVE: To compare energy expenditure rates in children playing the physically active video games, Dance Dance Revolution (DDR) and Nintendo's Wii Sports in relation to treadmill walking. METHODS: Energy expenditure, heart rate, step rate, and perceived exertion were measured in 14 boys and 9 girls (ages 10-13 years; BMI at 3-98th percentile for age and gender) while watching television at rest, playing DDR at 2 skill levels, playing Wii bowling and boxing, and walking at 2.6, 4.2, and 5.7 km/h. Arterial elasticity was measured at rest and immediately after gaming. RESULTS: Compared with watching television, energy expenditure while gaming or walking increased 2- to 3-fold. Similarly, high rates of energy expenditure, heart rate, and perceived exertion were elicited from playing Wii boxing, DDR level 2, or walking at 5.7 km/h. This occurred despite variations in step rate among activities, reflecting greater use of upper body during Wii play (lowest step rate) than during walking (highest step rate) or DDR play. Wii bowling and beginner level DDR elicited a 2-fold increase in energy expenditure compared to television watching. Large-artery elasticity declined immediately after both DDR and Wii. The change was inversely related to the increment in energy expenditure above rest achieved during the activity. CONCLUSIONS: Energy expenditure during active video game play is comparable to moderate-intensity walking. Thus, for children who spend considerable time playing electronic screen games for entertainment, physically active games seem to be a safe, fun, and valuable means of promoting energy expenditure.

Ser lutador traz mais prestígio?

Pesquisadores franceses investigaram se o envolvimento de homens com a luta trazia maior prestígio, maior acesso a companheiras e maior número de filhos. A resposta foi sim, embora as mulheres da etnia investigada tenham apontado o fato de ser lutador como um fator pouco relevante em suas escolhas.
Apesar da relação entre esses farores ser polêmica, vale a pena ler o texto inteiro (para aqueles que tiverem o acesso ao artigo na íntegra).
Eu recomendo, pois o texto está bem escrito.

Ritual fights and male reproductive success in a human population.
J Evol Biol. 2009 Sep;22(9):1854-9. Epub 2009 Jul 3.

Ritual fights are widespread across human populations. However, the evolutionary advantage associated with this behaviour is unclear because these fights rarely provide direct benefits such as territory, resources or mates. Here, the reproductive success of men competing in a traditional ritual fight, Sereer wrestling, was investigated for the first time. Involvement in wrestling had a significant positive effect on men's number of offspring and a marginally significant effect on polygyny, controlling for age, body condition and socio-economic status. These positive effects suggest that being involved in wrestling competition provides prestige, facilitating access to mates and thereby increasing fecundity. However, when women were interviewed on their preference concerning qualities of potential mates, the quality 'being involved in wrestling competition' was poorly ranked. This discrepancy may arise either from deceptive reports or from discordance between parents and daughters in the choice of a husband.

Sports Injuries During the Summer Olympic Games 2008.

BACKGROUND: Standardized assessment of sports injuries provides important epidemiological information and also directions for injury prevention. PURPOSE: To analyze the frequency, characteristics, and causes of injuries incurred during the Summer Olympic Games 2008. STUDY DESIGN: Descriptive epidemiology study. METHODS: The chief physicians and/or chief medical officers of the national teams were asked to report daily all injuries newly incurred during the Olympic Games on a standardized injury report form. In addition, injuries were reported daily by the physicians at the medical stations at the different Olympic venues and at the polyclinic in the Olympic Village. RESULTS: Physicians and/or therapists of 92 national teams covering 88% of the 10977 registered athletes took part in the study. In total, 1055 injuries were reported, resulting in an incidence of 96.1 injuries per 1000 registered athletes. Half of the injuries (49.6%) were expected to prevent the athlete from participating in competition or training. The most prevalent diagnoses were ankle sprains and thigh strains. The majority (72.5%) of injuries were incurred in competition. One third of the injuries were caused by contact with another athlete, followed by overuse (22%) and noncontact incidences (20%). Injuries were reported from all sports, but their incidence and characteristics varied substantially. In relation to the number of registered athletes, the risk of incurring an injury was highest in soccer, taekwondo, hockey, handball, weightlifting, and boxing (all >/=15% of the athletes) and lowest for sailing, canoeing/kayaking, rowing, synchronized swimming, diving, fencing, and swimming. CONCLUSION: The data indicate that the injury surveillance system covered almost all of the participating athletes, and the results highlight areas of high risk for sport injury such as the in-competition period, the ankle and thigh, and specific sports. The identification of these factors should stimulate future research and subsequent policy change to prevent injury in elite athletes.

A randomized controlled trial of Kung Fu training for metabolic health in overweight/obese adolescents: the "martial fitness" study.

Resumo de artigo relacionando a prática de kung fu com melhoria da saúde em adolescentes obesos e/ou com sobrepeso

Twenty overweight/obese adolescents underwent six months of Kung Fu or placebo (Tai Chi) training, 3x.wk(-1). Outcomes included fasting insulin and insulin resistance, lipids, glucose and HbA(1c), and C-reactive protein (CRP). CRP decreased significantly (p = 0.03) in both groups over time at six months. Although insulin sensitivity did not change, HbA(1c) tended to decrease over time (p = 0.09), again with no group difference (p = 0.60). Reduced CRP was related to increased upper body strength (p = 0.01). Increased lean body mass was related to reductions in HbA(1c), insulin resistance, triglycerides, and total cholesterol. Improvements in lean body mass appear to have a potential role in favorable metabolic outcomes, independent of changes in fat mass. Further research in this area is warranted before definite conclusions can be drawn about the efficacy of martial arts training for metabolic outcomes in this cohort.
