IntroductionAerobic training of moderate intensity is the primary modality recommended in the management of hypertension. The manipulation of training variables can be an important strategy for the continuity of health benefits; however, little is known about the effects of the progression of aerobic training variables in the adaptations of blood pressure in hypertensive adults.ObjectiveTo analyze, through a systematic review with meta-analysis, the effects of aerobic training with and without progression on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in hypertensive adults.MethodThe search for the studies was carried out in the PubMed, Cochrane Central, SPORTDiscus and LILACS databases. Clinical trials that analyzed the effect of aerobic training, lasting at least six weeks, on blood pressure in hypertensive individuals comparing with a control group without intervention were selected. The selection of studies and data extraction were carried out independently by two pairs of researchers. The results are presented as mean difference and 95% confidence interval. Statistical significance was considered with p < 0.05.ResultsOf the 13,028 studies found, 24 were selected and included in this review, 12 with progression of training variables and 12 without progression, with a total of 1,207 participants analyzed. There was a reduction in SBP after aerobic training with progression (−10.67 mmHg; 95% CI −15.421, −5.926; p < 0.001) and without progression (−10.17 mmHg; CI −12.213, −8.120; p < 0.001). DBP also decreased after aerobic training with progression (−5.49 mmHg; 95% CI −8.663, −2.310; p < 0.001) and without progression (−6.51 mmHg; 95% CI −9.147, −3.868; p < 0.001). According to the results of the meta-regression analyses, only age showed an association with the reduction of SBP (β: −0.323; CI −0.339, −0.307; p < 0.001).ConclusionAerobic training promotes a reduction in the SBP and DBP levels of adults with hypertension, regardless of whether or not the training variables progression.

Abstract Objective: The aim of the present study was to verify the behavior of hemodynamic variables in hypertensive older women following a combined exercise session and to identify the intensity of effort achieved in this session. Method: The study included 14 hypertensive older women (72.0±6.7 years old) who regularly practiced physical activities. The participants underwent a one-hour combined exercise session performed in a group, with intensity of effort monitored by accelerometry (Actigraph, model GT3X+). The hemodynamic parameters (systolic blood pressure, diastolic blood pressure, heart rate, stroke volume, cardiac output and peripheral vascular resistance) were individually measured by finger photoplethysmography (Finometer) before and after (60 min) the exercise session. Results: The sessions consisted predominantly of low-light intensity activities (60%) and 20% of class time was spent on sedentary behavior. None of the evaluated variables exhibited changes when the pre and post-exercise values were compared (p>0.05). Systolic blood pressure behavior correlated positively with time spent in sedentary behavior (r=0.541; p=0.045). Conclusion: The combined exercise sessions, as conducted, did not generate post-exercise hypotension. In addition, the time spent in typically sedentary activities during the classes positively correlated with changes in blood pressure, suggesting that combined exercise programs, applied in the form of collective aerobic exercises, should be composed of higher intensity activities.

O estudo teve por objetivo comparar o efeito do treinamento físico, com e sem periodização, nos níveis de atividade física diária e no tempo em comportamento sedentário de adultos com obesidade. Em um estudo randomizado controlado, 69 adultos de ambos os sexos com obesidade (IMC ≥ 30 kg/m²) foram randomizados em três grupos: grupo periodizado (GP), grupo não periodizado (GNP) e grupo controle (GC). Os grupos periodizado e não periodizado foram submetidos a 16 semanas de treinamento físico combinado (aeróbio e resistido) e supervisionado, três vezes na semana, em sessões de 60 minutos. Os níveis de atividade física e comportamento sedentário foram mensurados por meio de acelerometria (Actigraph - GT3x). O tempo despendido em comportamento sedentário após a intervenção aumentou 6,5% no GP e 1,2% no GC e reduziu 0,5% no GNP. As mudanças nos níveis de atividade física leve foram de -4,6% no GP, +0,5% no GNP e -2,3% no GC, ao passo que os níveis de atividade física moderada a vigorosa apresentaram reduções de 3,0% no GP e aumentos de 0,5% no GNP e 12,2% no GC. Vale destacar, porém, que não foram identificados efeitos isolados do tempo e do grupo e nem interação tempo e grupo para nenhuma das variáveis analisadas (p > 0,05). Um programa de treinamento físico combinado e supervisionado, com ou sem progressão de carga, não foi capaz de promover mudanças no comportamento sedentário e nos níveis de atividade física de adultos com obesidade, sendo necessárias ações específicas voltadas a estes comportamentos.
