Resistance training attenuates the effects of aging in the aorta of Wistar rats

Abstract: The objective of the present study was to follow the structural modifications of the aortic wall in middle-aged rats submitted to a resistance training protocol for a period of four months. Three groups of 8 animals per group were considered: middle-aged group (MA), old control group (OC) and old trained group (OT). Training consisted in to climb a 1.1-m vertical (80° incline) ladder with weights tied to their tail. Aortic wall structural modifications were studied through light and electron microscopy and morphometry. The mean arterial blood pressure at rest was similar in the three experimental groups (p = .07). At the beginning of the experiment, the OC and OT groups had similar repetition maximums, ranging from 1.6-fold to 1.9-fold the body weight. At the end of the experiment, the repetition maximum of the OT group was 5-fold greater than the body weight (p = .03). The LV weight was 15% larger in the OT group than in the MA group and 12% larger than in the OC group (p = .02). The LV wall thickness of the OT group was significantly larger than that of both, the MA group and the OC group (p = .03). The LV internal diameter in the OT group was significantly smaller than that observed in the MA and OC groups (p = .02). Resistance training diminished the alterations associated with aging improving aortic wall structure by reducing the thickness, normalising the elastic material, the collagen and the smooth muscle cells. Resistance training seems to be a potential treatment for reducing the deleterious effects of aging on the aortic wall.

Desempenho do profissional de educação física em casos de parada cardiorrespirátoria: considerações sobre a formação profissional

Abstract: O conhecimento dos profissionais da area da saude no que se refere ao pronto-atendimento em situacoes de emergencia, como na parada cardiorrespiratoria (PCR), e fundamental para sua formacao, uma vez que em seu ambiente de trabalho lidam com pessoas que podem sofrer um evento subito. O objetivo deste estudo e contribuir com a formacao do profissional de Educacao Fisica (EF) em relacao ao conhecimento sobre intervencao primaria em PCR e reanimacao cardiopulmonar (RCP), apresentando observacoes e sugestoes a respeito da formacao inicial e continuada. Trata-se de uma pesquisa qualitativa, envolvendo 24 profissionais de EF que trabalham em academias da zona leste de Sao Paulo, de ambos os sexos, com no minimo dois e no maximo 12 anos de formados, que foram submetidos a uma intervencao didatica na qual foi sondado o conhecimento teorico e pratico acerca do assunto por meio de um questionario fechado com 21 questoes, das quais 13 referentes a identificacao do respondente e aspectos relativos a sua formacao inicial, e oito para avaliar os conhecimentos tecnicos em relacao ao atendimento de primeiros socorros com o uso da manobra de RCP em possiveis causas de eventos subitos. Apos o preenchimento do questionario, participaram, individualmente, de uma simulacao de atendimento a PCR em adulto, utilizando um boneco para treinamento, em que deveriam executar as tecnicas de RCP estabelecidas pela diretriz de 2005 da American Heart Association (AHA). Foi usada uma ficha de observacao com a finalidade de obter dados que permitiram identificar o conhecimento via aplicacao das tecnicas de RCP, verificando seu conhecimento teorico-pratico para uma intervencao. A etapa seguinte constou de um treinamento teorico-pratico de quatro horas/aula, no qual puderam se atualizar com relacao as novas diretrizes da AHA/2010; apos o curso, responderam a um questionario com quatro questoes abertas em que se manifestaram a respeito do conteudo do curso e fizeram observacoes sobre 144 a formacao inicial e continuada. O estudo concluiu que e recomendavel a oferta permanente de atualizacao de profissionais de EF em relacao a PCR e RCP. Palavras-chave: parada cardiorrespiratoria; educacao fisica; formacao continuada.

Efecto del entrenamiento de fuerza en las variables cardiovasculares en adolescentes con sobrepeso

Abstract: OBJETIVO: O presente estudo teve por objetivo avaliar as respostas agudas cardiorrespiratorias e autonomicas induzidas por uma sessao de exercicio fisico resistido em adolescentes com sobrepeso.METODOS: Foram avaliados 17 adolescentes do sexo masculino divididos em grupo controle (GC, n=9) e grupo sobrepeso (GSO, n=7). Todos foram submetidos a uma sessao exercicios resistidos para diferentes grupos musculares, realizados com sobrecarga de 60% da forca maxima, com um intervalo de 45 segundos entre as series e 90 segundos entre cada exercicio. Antes, durante e apos a sessao de exercicios os seguintes parâmetros foram avaliados: frequencia cardiaca (FC), pressao arterial sistolica (PAS), pressao arterial diastolica (PAD) e variabilidade da frequencia cardiaca (VFC).RESULTADOS: Foi observado comportamento semelhante em ambos os grupos da PAS e PAD. A PAS aumentou durante o exercicio e a PAD diminuiu. Ambas retornaram aos valores basais durante a recuperacao. A FC aumentou durante a sessao de exercicio nos dois grupos, porem, apenas no GSO houve retorno aos valores de repouso. Os indices da VFC no dominio do tempo (VAR RR e RMSSD) se comportaram de maneira semelhante frente ao exercicio nos dois grupos, porem, no indice SDNN apenas o GSO retornou aos valores de repouso. A VFC no dominio da frequencia apresentou comportamento semelhante em ambos os grupos.CONCLUSOES: sugere-se que o aumento do nivel de atividade fisica em individuos com sobrepeso pode prevenir as alteracoes autonomicas que estao associadas ao aumento do peso corporal e conferir efeito protetor ao sistema cardiovascular.

Autonomia e esclarecimento: o projeto crítico enquanto projeto político

Abstract: Using the concepts of enlightenment and autonomy, the aim of this article is to build a question in the kantian philosophy about the necessity to comprehend the critical project also as a political project. However, to do so it is required to confront the contemporary tradition that begins with Hegel and persist until Habermas, in which the idea of Critique is regarded as an empty and passive element (since grounded in the abstraction of the moral law). The article will point out an interpretation in which the practical faculty of judgment, in its reflexive and determining activity, would unify the political and juridical elements that find its counterpart in the so called “critical epoch”.

Effects of Aerobic exercise of different intensities in the liver of Metabolic Syndrome animals

Abstract: Introduction: Metabolic syndrome (MS) corresponds to a sum of alteration in which, glucose intolerance is characterized as one of the most important. Among these are included: insulin resistance, type 2 diabetes mellitus, hypertension, obesity, dyslipidemia, endothelial dysfunction and others Nonalcoholic steatohepatitis (NASH) is also currently cited as a risk factor for MS Studies have demonstrated a strong correlation between physical inactivity and MS. The aim of this paper was to evaluate the effects of aerobic exercise training of different intensities on the liver of metabolic syndrome rats. Methods: 20 male Wistar rats were used and divided into four groups (n=5): control (C) sedentary MS (MS), walking MS (WMS) and running MS (RMS). Fructose-drinking rats received D-fructose (100 g/l). MS Training rats were assigned to a treadmill training protocol at low and moderate intensity during 1 h/day, 5 days/week for 8 weeks. At the end of the experiment, the livers were collected and submitted to a histological technique (HE). The images were captured and morphometric and stereological analysis of the hepatic tissue were performed. Results: It was verified that MS promoted a hypertrophy of the hepatocytes, a significant increase in the density volume of the hepatocytes, of the Kupffer cells, and hepatic sinusoids, and that, in both intensities (Running and Walking) the exercise training has mitigated the alterations. Conclusions: The data suggest, as nonpharmacological treatment, the walking (low intensity) is the most eficient, able to reverse the alterations caused by metabolic syndrome, the results being approximate to those of control group.
