ARTIGO DE REVISÃO | REVIEW ARTICLE RESUMOObjetivou-se revisar sistematicamente estudos randomizados sobre a magnitude da hipotensão pós-exercício (HPE) em adultos. Consultaram-se as bases Pubmed, Scielo e Lilacs, combinando os indexadores "exercise" e "hypotension", sendo encontrados 1336 estudos. Destes, excluíram-se 1268 por títu-los, 37 por resumos, 10 não randomizados, 1 por repetição de dados, restando 20. Estes foram avaliados segundo os itens de randomização, mascaramento, sigilo de alocação, análise por intenção de tratar e quantitativamente pela Escala de Jadad. As reduções das pressões sistólica (PAS) e diastólica (PAD) em normotensos foram inferiores à dos hipertensos (−9±3 vs −11±6 mmHg e −5±2 vs −8±6 mmHg, respetivamente). Em ambos os grupos, os indivíduos ativos apresentaram HPE maior que os sedentários (normotensos: PAS −10±4 vs −8±1 mmHg; PAD −5±1 vs −4±1 mmHg; hipertensos: PAS −16±4 vs −9±2 mmHg; PAD −7±4 vs −5±3 mmHg, respetivamente). Nestes estudos, a magnitude da HPE variou entre −4 a −19 mmHg para PAS e −2 a −9 mmHg para PAD, valores que dependem tanto das características da amostra, seus estágios pressóricos iniciais, sexo e nível de atividade física, como também do protocolo de exercício utilizado, não havendo consenso sobre a influência da sua duração ou da intensidade do exercício. Palavras-chave: exercício, pressão arterial, hipotensão pós-exercício ABSTRACTThe objective was to carry out a systematic review of randomized trials on the magnitude of post exercise hypotension (PEH) in adults. 1336 studies were retrieved from PubMed, Scielo and Lilacs, after searching "exercise" and "hypotension". 1268 papers were excluded by titles, 37 by abstracts, 10 were nonrandomized, 1 by repeating data, leaving 20. These studies were evaluated according to the randomization, blinding, allocation concealment, analysis by intention to treat and quantitatively by the Jadad Scale. The average reductions in systolic (SBP) and diastolic (DBP) of the normotensive were lower than hypertensive (−9±3 vs. −11±6 mmHg and −12±2 vs. −8±6 mmHg, respectively) in both groups, active individuals had greater PEH than sedentary individuals (normotensive SBP −10±4 vs. −8±1 mmHg, PAD −5±1 vs. −4±1; hypertensive SBP −16±4 vs −9±2 mmHg; PAD −7±4 vs. −5±3 mmHg, respectively). In randomized studies the magnitude of PEH ranged from −4 to −19 mmHg for SBP and −2 to −9 mm Hg for DBP values according to the sample characteristics (blood pressure early stages, gender and level of physical activity) and the exercise protocols selected (i.e., there is no consensus on the influence of duration and intensity).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
