Fundamento: A COVID-19 afetou como as pessoas recebem atendimento de saúde para várias doenças, inclusive doenças cardiovasculares. Objetivos: Examinar as percepções dos participantes de reabilitação cardíaca (RC) sobre seus comportamentos em saúde e necessidades de informação durante a pandemia da COVID-19 no Brasil. Métodos: Neste estudo transversal, um questionário de 27 itens elaborado pelos investigadores foi administrado online a participantes de dois programas de RC. As perguntas incluíam letramento em saúde (LS; usando a Brief Health Literacy Screening Tool -Breve ferramenta de triagem de letramento em saúde), uso de tecnologia, percepções antes e durante a pandemia da COVID-19, e necessidades de informações. Foram usados coeficiente de correlação de Pearson, testes t pareados e ANOVA, conforme apropriado. Um p <0,05 foi considerado estatisticamente significativo para todos os testes. Resultados: No total, 159 (25,5%) participantes de RC responderam ao questionário. Desses, 89,9% tinham LS limitado ou marginal, e 96,2% relataram ter acesso à internet de casa. Os pacientes se preocupam principalmente com a saúde de sua família e própria, além de como o coronavírus é perigoso para sua saúde e como mudou seu estilo de vida. Os participantes perceberam que a qualidade de seus comportamentos em saúde diminuiu significativamente durante a pandemia. A pandemia também mudou as necessidades de informações dos participantes de RC, já que novas necessidades surgiram, tais como, controle de níveis de ansiedade, manter a motivação para levar uma vida saudável durante a pandemia, e como a COVID-19 pode afetar sua condição de saúde. Participantes com LS adequado perceberam significativamente a gravidade da doença e tinham significativamente mais acesso a informações do que os pacientes com LS limitado. Conclusões: Nossos resultados destacaram o impacto da pandemia nas percepções dos participantes de RC em relação a seus comportamentos em saúde e necessidades de informação, que podem ser influenciados pelos níveis de LS.

Objective To evaluate the effects of physical exercise on autonomic dysfunction in patients with fibromyalgia syndrome (FM). Literature Survey and Methodology A systematic review of experimental studies published until December 2017 that analyzed the effect of physical exercise on autonomic dysfunction in patients with FM was performed using the PubMed, Pedro, Scopus, ScienceDirect, and Web of Science databases. Synthesis A total of 1105 articles were identified, 12 of which were included in the final analysis. The most analyzed exercise modalities were aerobic and resistance exercises. Overall, the studies demonstrated that aerobic exercise performed twice a week with moderate to high intensity was effective in reducing autonomic dysfunction by increasing heart rate variability. Resistance training was associated with reduced symptoms of anxiety and depression as well as increased muscle strength; however, it did not reduce autonomic dysfunction in these patients in the short or long term. Conclusions Preliminary evidence suggests that aerobic exercise reduces autonomic dysfunction in patients with FM, whereas resistance training reduces psychological symptoms such as anxiety and depression. Level of Evidence I

Homens e mulheres foram estudados em relação à corporeidade e orientação motora na dança. O objetivo foi analisar a percepção corporal e preferências motoras entre praticantes. Utilizou-se o Questionário de Identidade Corporal, com praticantes de hip-hop, clássico, contemporâneo, dança de salão, axé, jazz e dança do ventre. Verificou-se que os homens tocam e conhecem mais seus corpos do que as mulheres, levando-os a uma visão funcional e as mulheres uma visão estética. Eles preferem atividades competitivas e agressivas e elas atividades individualizadas. Percebe-se que os tradicionais papéis sexuais também são impactantes na identidade de gênero dos praticantes de dança.

The heart rate behavior during physical activities and sexual intercourse is considered a major concern for patients after a cardiovascular event. Despite the intense physical effort being a precipitating factor for myocardial infarction and sudden death, the metabolic expenditure in daily activities is discreet and can be maintained by most patients. The objective of this study was to evaluate the relationship of heart rate at maximal exercise test in comparison with daily activities. The participant of this case study is a 36 year-old man without evidence of cardiovascular disease. The participant was submitted to an exercise test. The heart rate behavior was monitored during 14 days, with a portable frequency meter. During the 14 days, six activities were chosen: an ordinary 5 Km/h walk, a 6.5 Km/h run, recreational soccer, sexual intercourse, self-stimulation through masturbation and sleep time. As a result, the recreational soccer practice was characterized as intense and very intense effort, the sexual intercourse and the masturbation had slight increase in heart rate and the orgasm reached similar intensity to ordinary walk.

Elderly population often is encouraged to practice sports in preventing cardiovascular diseases. However, evidences exist that intense physical efforts are related with a higher risk for acute myocardial infarction and sudden death. Biological markers for myocardial injury was analyzed in a group of 15 elderly athletes without a history of coronary artery disease, who participated in the 77th International Sao Silvestre race (15,000 m) in Sao Paulo City. A statistical difference was observed between total CPK activity levels before the run, immediately after the run, and some time later. Similar results were observed in the concentration of CK-MB mass. The cardiac troponin I (TnI-c) levels remained unchanged and within normal limits during the same time periods. The results of the present study showed no evidence of myocardial injury in elderly subjects without a history of coronary artery disease after participating in long-distance runs, as confirmed by the analysis of TnI-c levels. The increase in total CPK activity levels and the concentration of CK-MB mass do not represent myocardial injury in these subjects.
