Hipotensão pós-exercício em indivíduos hipertensos: uma revisão

Abstract

Post-exercise hypotension (PEH) may follow a session of physical exercises. This effect has high clinical relevance for hypertensive individuals. Although there are several studies on the subject, an analysis is still lacking on a state-of-art approach considering different types of exercises.Using a review of literature, the aim of this paper was to verify the relationship between aerobic exercise and resistance exercise in PEH in hypertensive people.For the purpose of this study, Scielo and Medline databases were surveyed, and the main inclusion criteria were studies on the subject in English language and a sample of hypertensive adults. One hundred and twenty-six studies were found. However, only 32 papers, 5 of which on resistance exercise and 27 on aerobic exercise were used for this study. Although the studies surveyed used different prescription models for resistance exercise, PEH was observed mainly in the laboratory setting. After aerobic exercise, it was noted that PEH occurred for longer periods. However, there are differences of opinion as to the best intensity and duration of the exercise to be prescribed. Therefore, in hypertensive individuals declines in arterial pressure following aerobic exercise are apparently greater than those observed with resistance exercise. Nevertheless, in order to achieve sounder conclusions, further studies on ambulatory blood pressure monitoring should be conducted.

Blood pressure responses after a session of functional training in young adults and the elderly: a pilot study

“…The former ones, although they do not confer adverse risks to participants, are bound with several methodological weaknesses (small sample size, heterogeneous results and protocols, and lack of appropriate control groups) that prevent practical recommendations to be formulated for hypertensive populations [16,29]. On the other hand, the exercise techniques, which comprise a wide variety of methods/types, have acquired consolidated body of evidence referring to the prevention/minimization of higher BP [17].…”

“…Besides the BP levels at baseline, the type of exercise performed also influences the magnitude of PEH [17]. The majority of studies show that aerobic exercises are more effective in promoting PEH in comparison with resistance exercises.…”

“…There is substantial evidence showing that BP decreases following these dynamic exercises, a phenomenon called post-exercise hypotension (PEH) [16]. It is well accepted that cardiovascular responses are influenced by training variables, such as exercise execution time (or number of repetitions), load, muscle mass recruited and type of contraction [15,17,18]. To our knowledge, there is no previous research that would observe the influence of these variables on BP following FT sessions.…”

Caracterização da resposta hipotensora pós-exercício

“…Assim, por um lado, a realização de atividade e/ou exercício físico é importante no tratamento não farmacológico para a redução da PA. Por outro, ainda não está definido o melhor tipo de exercício, sendo o aeróbio o mais indicado, segundo os artigos pesquisados [22][23][24][25][26][27] .…”

Influência do número de séries nos ajustes cardiovasculares e autonômicos ao exercício resistido em homens fisicamente ativos

“…There is evidence that a single session of rE promotes BP reduction in hypertensive 5 and normotensive individuals 6 and these responses may be related to the sessions volume/intensity 7 . Among the mechanisms associated with the BP reductions are alterations in cardiac sympathovagal modulation.…”
