Resumo O objetivo deste trabalho é propor sugestões práticas para a atuação no atendimento à população em situação de rua diante da pandemia da COVID-19 no Brasil. Com base numa pesquisa qualitativa contendo entrevistas com profissionais da área, análise de informações levantadas num portal de notícias de amplitude nacional e levantamento de artigos, relatórios de pesquisa e documentos informativos de outros países, sugerimos algumas estratégias que podem contribuir para a atuação da gestão municipal, sobretudo no âmbito da assistência social e nos equipamentos de assistência às pessoas em situação de rua no Brasil. Nossos resultados são parciais, embora incluam um panorama comparativo que permite inclusão de estratégias, ao que parece, ainda não implementadas no país. Destacamos também algumas questões que precisam ser repensadas pelos governos federal, estadual e municipal diante da urgência da implementação de políticas durante a pandemia da COVID-19.

Biomarkers of inflammation, muscle damage, and oxidative stress after high-intensity exercise have been described previously; however, further understanding of their role in the postexercise recovery period is necessary. Because these markers have been implicated in cell signaling, they may be specifically related to the training adaptations induced by high-intensity exercise. Thus, a clear model showing their responses to exercise may be useful in characterizing the relative recovery status of an athlete. The purpose of this study was twofold: (a) to investigate the time course of markers of muscle damage and inflammation in the blood from 3 to 72 hours after combined training exercises and (b) to investigate indicators of oxidative stress and damage associated with increased reactive oxygen species production during high-intensity exercise in elite athletes. Nineteen male athletes performed a combination of high-intensity aerobic and anaerobic training exercises. Samples were acquired immediately before and at 3, 6, 12, 24, 48, and 72 hours after exercise. The appearance and clearance of creatine kinase and lactate dehydrogenase in the blood occurred faster than previous studies have reported. The neutrophil/lymphocyte ratio summarizes the mobilization of 2 leukocyte subpopulations in a single marker and may be used to predict the end of the postexercise recovery period. Further analysis of the immune response using serum cytokines indicated that high-intensity exercise performed by highly trained athletes only generated inflammation that was localized to the skeletal muscle. Biomarkers are not a replacement for performance tests, but when used in conjunction, they may offer a better indication of metabolic recovery status. Therefore, the use of biomarkers can improve a coach's ability to assess the recovery period after an exercise session and to establish the intensity of subsequent training sessions.
