The present study investigated whether the practice of exercise has a protective effect against cardiac toxicity induced by doxorubicin (DOX). A systematic review of randomized clinical trials evaluating the role of exercise in the control or prevention of DOX-induced cardiotoxicity was performed in MEDLINE and LILACS databases. Studies that did not address the main subject of this review, did not mention physical exercise or DOX, studies that evaluated other types of anthracycline-induced toxicities only (muscle, hepatic and renal toxicity) or other effects of exercise on DOX toxicity (fatigue) were excluded. With respect to the variables related to aerobic exercise prescription, there was no direct relationship between the frequency of exercise and the results of the studies. Also, intensity of exercise was not decisive for preservation of cardiac function, although a more intense exercise was associated with improvements in the antioxidant system, which was not observed in studies on lower intensity exercises. No significant differences in exercise effects were observed when it was performed before, during or after the treatment. Therefore, aerobic exercise may exert a protective effect of cardiac functions when performed before, during or after treatment with DOX. However, the mechanisms of this effect are still unknown.
O presente estudo teve como objetivo investigar o Rio Mountain Festival e sua relação com as atividades de aventura e na natureza, pois o mesmo exerce um importante papel no cenário brasileiro. Foi possível identificar como surgiu esta mostra, bem como, sua organização, critérios adotados para a escolha do filme e frequentadores deste relevante espaço de lazer. Ao longo dos anos verifica-se como a estrutura da mostra influencia o público presente. As análises dos filmes permitem concluir que a mostra exerce um duplo papel no que se refere ao imaginário social das atividades de aventura e na natureza. Ao mesmo tempo em que os filmes são produtores de novos conceitos e estilos de vida que vão modificar o imaginário social já existente, são produtos deste, uma vez que representam aquilo que se passa nestas atividades.
<p class="ResumoeAbstract">O objetivo desse estudo é analisar as possibilidades do ensino das atividades circenses, mediadas pelas TICs, durante o ensino remoto. A pesquisa, documental, partiu dos Relatórios do Projeto de extensão, sob os quais lançamos as luzes das referências da área; bibliográfica. Apesar das contradições, próprias do ensino remoto, avaliamos o êxito de algumas atividades, como o acesso e a produção de vídeos acerca do temário, perspectivados como possíveis auxiliares à docência das atividades circenses presenciais.</p>
