Metabolic and cardiac autonomic effects of high-intensity resistance training protocol in Wistar rats.

The aim of this study was to assess the effects of metabolic and autonomic nervous control on high-intensity resistance training (HRT) as determined by pancreatic glucose sensitivity (GS), insulin sensitivity (IS), blood lactate ([La]), and heart rate variability (HRV) in rats. Thirty male, albino Wistar rats (292 ± 20 g) were divided into 3 groups: sedentary control (SC), low-resistance training (LRT), and HRT. The animals in the HRT group were submitted to a high-resistance protocol with a progressively increasing load relative to body weight until exhaustion, whereas the LRT group performed the same exercise regimen with no load progression. The program was conducted 3 times per week for 8 weeks. The [La], parameters related to the functionality of pancreatic tissue, and HRV were measured. There was a significant increase in peak [La] only in the HRT group, but there was a reduction in [La] when corrected to the maximal load in both trained groups (LRT and HRT, p < 0.05). Both trained groups exhibited an increase in IS; however, compared with SC and LRT, HRT demonstrated a significantly higher GS posttraining (p < 0.05). With respect to HRV, the low-frequency (LF) band, in milliseconds squared, reduced in both trained groups, but the high-frequency band, in milliseconds squared and nu, increased, and the LF in nu, decreased only in the HRT group (p < 0.05). The HRT protocol produced significant and beneficial metabolic and cardiac autonomic adaptations. These results provide evidence for the positive benefits of HRT in counteracting metabolic and cardiovascular dysfunction.

Pé torto congênito: método de Ponseti e sua aplicabilidade pelo fisioterapeuta / Congenital clubfoot: Ponseti method and its applicability by the physiotherapist

O pé torto congênito é uma das deformidades mais frequentes de membro inferior que, por sua complexidade com relação às alterações anatômicas, é alvo de dúvidas e divergência de opinião dos profissionais da área quanto ao tratamento mais eficaz. No entanto, o método mais utilizado atualmente e que vem apresentando resultados positivos é o de Ponseti. O objetivo deste trabalho é analisar a eficácia do método de Ponseti e sua aplicabilidade pelo fisioterapeuta. Tratou-se de pesquisa do tipo revisão, com abordagem qualitativa por meio de consulta a publicações das bases de dados Scielo, Lilacs, Medline e Bireme, preferencialmente dos últimos dez anos, e a coleta de dados no mês de outubro de 2016. Foram encontradas 248 publicações e, após análise, foram selecionados 23 artigos para a pesquisa, distribuídas em duas categorias: Eficácia do método Ponseti e Eficácia das técnicas fisioterapêuticas. Diante do exposto, percebese que o método de Ponseti tem se mostrado o mais eficaz no tratamento do pé torto congênito, e suas técnicas são compatíveis com as utilizadas por fisioterapeutas, sendo possível sua aplicabilidade por este profissional, com exceção da tenotomia do calcâneo. Portanto, este trabalho abre espaço para novas pesquisas que corroborem esta temática. (AU)

The congenital club foot is one of the most frequent lower limb deformities that, due to its complexity in relation to anatomical changes, is the subject of doubts and divergence of opinion of professionals in the area regarding the most effective treatment. However, the method most used currently and that has presented positive results is that of Ponseti. The aim of this study was to analyze the effectiveness of the Ponseti method and its applicability by the physiotherapist. This research was a literature review, with a qualitative approach, through consultation of publications of Scielo, Lilacs, Medline and Bireme databases, preferably in the last ten years, and data collection in October 2016. We found 248 publications and after analysis, 23 articles were selected for the research, distributed in two categories: Efficacy of the Ponseti method and Efficacy of physiotherapeutic techniques. The Ponseti method has been shown to be the most effective in the treatment of congenital clubfoot, and its techniques are like those used by physiotherapists, being possible its applicability by this professional, except for tenotomy of the calcaneus. Therefore, this work opens space for new research that corroborates this theme. (AU)
