O presente trabalho tem como objetivo estabelecer critérios e protocolos de atendimento para o Profissional de Educação Física (PEF) poder aplicar a avaliação da aptidão física e prescrever exercícios físicos para indivíduos pós-infecção por COVID-19 de forma individualizada e específica com a gravidade da infecção. O protocolo de atendimento para PEF é uma ferramenta para legitimar a inserção dessa classe profissional no contexto da saúde. Importante salientar que mesmo antes da pandemia estes protocolos já deveriam fazer parte do arsenal de procedimentos para o atendimento à população, devendo constar de avaliação pré-participação e avaliação da aptidão física, sendo agora adaptados à nova realidade da era COVID-19. Desta forma, torna-se de fundamental importância que a intervenção do PEF seja pautada nestes protocolos para que a sociedade reconheça essa classe profissional como profissionais da saúde e assim possam haver contribuições significativas para a saúde populacional, principalmente no contexto da pandemia COVID-19.

Introduction: Few studies have analyzed the association between physical activity and hospitalizations or mortality as a result of the new coronavirus, particularly in Brazil. Objective: To analyze the association between physical activity and deaths by Covid-19 in the Brazilian capitals. Method: An observational cross-sectional ecological study, in which data on the prevalence of physical activity during leisure time, and deaths by Covid-19 were analyzed for twenty-six Brazilian capitals plus the Federal District. Data were collected through the Risk Factor Surveillance System for chronic non-communicable diseases, and SUS Analytical for COVID-19 in Brazil, of the Brazilian Ministry of Health. For the data analysis, simple Pearson correlation and multiple regression were used, with a level of significance of 5%. Results: The data show the existence of an inverse correlation between physical activity during leisure time and accumulated deaths (r = −0.44, p = 0.03), mortality rate/100,000 inhabitants (r = −0.43, p = 0.02), and the lethality of the disease (r = −0.51, p = 0.01). They also show an inverse association between physical activity during leisure time and accumulated deaths (β = −485.1, p = 0.04), as well as with the lethality of the disease (β = −0.21, p = 0.02), even after adjusting for confounding variables. Conclusion: The inverse association observed between physical activity, accumulated deaths, and lethality of Covid-19 can bring important reflections on the actions that have been implemented by government agencies, at both state and municipal levels, in relation to the practice of physical activity by the population. Level of evidence III; Cross-sectional ecological study.

O presente ensaio teórico tem como objetivo analisar a interface entre as pandemias de inatividade física, obesidade e COVID-19, chamando a atenção para a importância de continuar e/ou aumentar a prática de atividade física como estratégia para minimizar os efeitos adversos da atual e de possíveis futuras pandemias, que possam exigir o distanciamento social. Considerando os benefícios da prática regular de atividade física para os sistemas cardiometabólico e imunológico, bem como para a saúde mental, é muito importante que as pessoas sejam conscientizadas para continuidade desse comportamento durante o período da pandemia do COVID-19, para assim, melhor suportar os efeitos de uma possível contaminação por infecções virais. O aumento dos níveis de atividade física na população pode ajudar a combater a obesidade e outros distúrbios cardiometabólicos, além de melhorar a saúde mental e a função imunológica, e, consequentemente nos preparar melhor, tanto para a atual pandemia de COVID-19, quanto para outras futuras pandemias com características similares.

Introduction The novel coronavirus pandemic recently declared by the World Health Organization has led several municipal and state health departments to issue decrees closing different spaces intended for practicing physical activity. Furthermore, the Ministry of Health has prepared a manual with several initiatives to prevent the spread of the disease, in addition to making decisions suggesting social isolation and recommending that people remain at home. All of these measures have made it more difficult for the Brazilian population to practice [...]

A manutenção do funcionamento dos centros de condicionamento físico durante a pandemia da Covid-19 pode proporcionar benefícios econômicos, bem como importantes vantagens para a promoção da saúde da população. O objetivo deste estudo foi identificar o tempo de permanência nas atividades laborais em funcionários de um centro de condicionamento físico, que utiliza protocolos de biossegurança, durante a pandemia Covid-19. A amostra foi composta por 64 funcionários de um centro de condicionamento físico da cidade de Salvador, Bahia, Brasil que foram acompanhados no período de 11 de agosto de 2020 até 01 de março de 2021 (200 dias). Os dados foram analisados por meio das curvas de sobrevida de Kaplan-Meier. A comparação das curvas do tempo em dias, considerando cada variável selecionada até a ocorrência do afastamento ao trabalho, em função de teste positivo para Covid-19, foi feita através do teste estatístico "Log-Rank. O tempo médio de permanência nas atividades laborais foi de 195,1 dias, com apenas 4 (6,2%) do total de funcionários sendo afastados do trabalho por testar positivo para Covid-19. Em contrapartida, 60 (93,8%) dos colaboradores permaneceram no trabalho sem afastamento por Covid-19. As variáveis sexo e idade não foram identificadas como potenciais determinantes do tempo até a ocorrência do afastamento, enquanto que entre os colaboradores de serviços administrativos, apesar do baixo quantitativo, ocorreu mais afastamentos. Os resultados deste estudo indicam que a possibilidade de infecção por Covid-19 em centros de condicionamento físico parece ser baixa, principalmente quando os protocolos de biossegurança determinados pelas autoridades sanitárias são cumpridos.

Dear Editor, In response to the letter to the editor entitled “Declaring physical activity as ‘essential’ during the Covid-19 pandemic may not be a good measure” that presented contributions to our point of view entitled “Should physical activity be considered essential activity during the Covid-19 pandemic?” we thank you for the suggestions and we present a reply letter with our arguments: […] The Big Mistake of not Considering Physical Activity an Essential Element of Care During the Covid-19 Pandemic

Background: recent points of view catch us attention to the importance of continuing to practice physical activity during the Covid-19 pandemic, however few studies have analyzed the association between physical activity and worsening of the clinical outcome, hospitalizations or mortality from the new coronavirus Objective: to analyze the association between physical activity and deaths by Covid-19 in the Brazilian capitals. Methods: observational cross-sectional ecological study, when data on prevalence of leisure time physical activity and deaths by Covid-19 were analyzed in 26 Brazilian capitals and the Federal District as well. Data on the prevalence of leisure time physical activity, obesity and hypertension has been collected through the Risk Factors Surveillance System for chronic non-communicable diseases of the Brazilian Ministry of Health were used. Information on accumulated deaths, lethality of the disease and mortality rate were extracted from SUS(Brazil's Unified National Health System) Analytical: data on COVID-19 in Brazil, available on the website of the Brazilian Ministry of Health. For data analysis, simple Pearson correlation and multiple regression were used with a 5% significance level. Results: demonstrate the existence of an inverse correlation between leisure time physical activity and accumulated deaths (r = -0.44, p = 0.03), mortality rate/100,000 inhabitants (r = -0.43, p = 0.02) as well as with the lethality of the disease (r = -0.51, p = 0.01). They also demonstrate an inverse association between leisure time physical activity and accumulated deaths (β = -485.1, p = 0.04), as well as with the lethality of the disease (β = -0.21, p = 0.02), even after adjusting for confounding variables. Conclusions: the practice of leisure time physical activity can be an important ally in coping with Covid-19. The inverse association observed among physical activity, accumulated deaths and disease lethality can bring important reflections on the actions that have been implemented by government agencies, both state and municipal regarding the practice of physical activity by the population.

Studies have shown reductions in the immune response capacity with the aging process (immunosenescence). Lifestyle factors (physical activity and diet) have been investigated as possible adjuvants to improve the effect of vaccines on the immune system in the elderly. The aim of this opinion article is to analyze studies on physical activity and the effect of influenza vaccines in an attempt to suggest that their results can also be found in future studies on physical activity and vaccines against COVID-19. Considering the results of the studies analyzed, it could be suggested that the practice of physical activity improves responses to the influenza vaccine. Thus, it could be assumed that, when transferring these findings to COVID-19, the importance of regular physical activity in the specific elderly population becomes extremely relevant during the COVID-19 pandemic.

the evaluation of the body fat distribution by anthropometry can serve to identify excess visceral fat. This diagnosis will enable implementation of specific measures to both prevent and treat excess visceral fat in postmenopausal women.the aim of this study was to analyze different anthropometric indicators and identify the best cutoff points to discriminate subjects with high visceral fat area (HVFA) in postmenopausal women.cross-sectional study with a sample of 255 postmenopausal women. Different Receiver Operating Characteristic (ROC) curves were constructed and the areas under them compared in terms of the conicity index (C-index), body mass index (BMI), waist-to-hip ratio (WHR), waist circumference (WC), weight-to-height ratio (WHtR) and HVFA. Sensitivity and specificity identified the best cutoff points between the different anthropometric indicators in order to discriminate subjects with HVFA. The confidence interval was set at 95%.statistically significant areas under the ROC curve were found for all anthropometric indicators analyzed. The following cutoff points, with their respective sensitivities and specificities to discriminate subjects with HVFA, were suggested: C-index (1.19; 75.00%- 74.77%); BMI (27.3 kg/m2; 81.08%-80.37%); WHR (0.98; 90.54%-83.18%); WC (85 cm; 85.14%-81.31%); and WHtR (0.55; 80.41%-80.37%).these results demonstrate that anthropometric indicators identify HVFA well in postmenopausal women and can be used instead of more sophisticated exams to detect high levels of visceral fat.Introducción: la evaluación de la distribución de la grasa corporal por antropometría puede servir para identificar el exceso de grasa visceral. Este diagnóstico permitirá la aplicación de medidas específicas para prevenir y tratar el exceso de grasa visceral en mujeres posmenopáusicas. Objetivo: el objetivo de este estudio fue analizar diferentes indicadores antropométricos e identificar los mejores puntos de corte para discriminar sujetos con alta área de grasa visceral (AAGS) en mujeres posmenopáusicas. Métodos: estudio transversal con una muestra de 255 mujeres posmenopáusicas. Se construyeron diferentes curvas Receiver Operating Characteristic (ROC) y las áreas bajo ellas comparadas en términos del índice de conicidad (índice C), el índice de masa corporal (IMC), razón cintura-cadera (RCC), circunferencia de la cintura (CC), relación cintura-estatura (RCEst) y AAGS. La sensibilidad y la especificidad identificaron los mejores puntos de corte entre los diferentes indicadores antropométricos para discriminar sujetos con AAGS. El intervalo de confianza se fijó en 95%. Resultados: las zonas estadísticamente significativas bajo la curva ROC se encontraron para todos los indicadores antropométricos analizados. Fueron sugeridos los siguientes puntos de corte, con sus respectivas sensibilidades y especificidades, para discriminar sujetos con AAGS: índice C (1,19; 75,00%–74,77%); IMC (27,3 kg / m2; 81,08%–80,37%); RCC (0,98; 90,54%-83,18%); CC (85 cm; 85,14%-81,31%); y RCEst (0,55; 80,41%–80,37%). Conclusión: estos resultados demuestran que los indicadores antropométricos identifican bien a las mujeres postmenopáusicas con AAGS y pueden ser utilizados en lugar de los exámenes más sofisticados para detectar altos niveles de grasa visceral.

Both abdominal obesity and sarcopenia are associated with cardiometabolic disorders mainly in postmenopausal women. In addition, there appears to be a reverse association between abdominal obesity and sarcopenia. The objective of the study was to identify the association and the discriminatory power of abdominal obesity for the prevention of sarcopenia and vice versa in postmenopausal women. The sample includes 257 women with age 57,2 years, The abdominal obesity and the variables determinants of sarcopenia were assessed by bioelectrical impedance analysis. The association of variables was been tested using logistic regression and the discriminatory power through Receiver Operating Characteristic (ROC) considering a confidence interval of 95%. The presence of abdominal obesity with the cutoff point of 153 cm² of visceral fat was discriminatory power for sarcopenia, as well as the musculoskeletal mass index with the cuttof point of 35,2% discriminated the absence of abdominal obesity. After adjusting for confounders it was observed still association between abdominal obesity and sarcopenia and association between musculoskeletal mass index and absence of abdominal obesity. The results of the study suggest that abdominal obesity discriminates and is associated with sarcopenia, such as musculoskeletal mass index discriminates the absence and is inversely associated whit of abdominal obesity in postmenopausal women.
