Kinetics of Hypotension during 50 Sessions of Resistance and Aerobic Training in Hypertensive Patients: a Randomized Clinical Trial

Abstract

BackgroundResistance and aerobic training are recommended as an adjunctive treatment for hypertension. However, the number of sessions required until the hypotensive effect of the exercise has stabilized has not been clearly established.ObjectiveTo establish the adaptive kinetics of the blood pressure (BP) responses as a function of time and type of training in hypertensive patients.MethodsWe recruited 69 patients with a mean age of 63.4 ± 2.1 years, randomized into one group of resistance training (n = 32) and another of aerobic training (n = 32). Anthropometric measurements were obtained, and one repetition maximum (1RM) testing was performed. BP was measured before each training session with a digital BP arm monitor. The 50 training sessions were categorized into quintiles. To compare the effect of BP reduction with both training methods, we used two-way analysis of covariance (ANCOVA) adjusted for the BP values obtained before the interventions. The differences between the moments were established by one-way analysis of variance (ANOVA).ResultsThe reductions in systolic (SBP) and diastolic BP (DBP) were 6.9 mmHg and 5.3 mmHg, respectively, with resistance training and 16.5 mmHg and 11.6 mmHg, respectively, with aerobic training. The kinetics of the hypotensive response of the SBP showed significant reductions until the 20th session in both groups. Stabilization of the DBP occurred in the 20th session of resistance training and in the 10th session of aerobic training.ConclusionA total of 20 sessions of resistance or aerobic training are required to achieve the maximum benefits of BP reduction. The methods investigated yielded distinct adaptive kinetic patterns along the 50 sessions.

Different volumes of repetitions and workloads in the pressor responses of hypertensive elderly: A systematic review

“…None of the studies hid criteria (PEDro scale, criterion 3). Three studies (da Cunha Nascimento et al, 2018;Damorim et al, 2017;Mota et al, 2013) demonstrated similarity between groups at the baseline moment (PEDro scale, criterion 4). None of the studies blinded methodological standards (PEDro scale, criteria 5.6 and 7).…”

“…Also, there was no high degree of variation in quality between studies. All assignments (da Cunha Nascimento et al, 2014, 2018Damorim et al, 2017;Mota et al, 2013) met the eligibility criteria (PEDro scale, criterion 1) and outcome measures. Only one study (Damorim et al, 2017) carried out a random crossover design (PEDro scale, criterion 2).…”

Saffron (Crocus sativus L.) in combination with resistance training reduced blood pressure in the elderly hypertensive men: A randomized controlled trial

“…The digital tool available at http://www.randomizer.org was used for randomization. Criteria for entering the study included age >60 years, high BP (SBP >140 mmHg and diastolic BP [DBP] >90 mmHg) in a continuous period shown by at least 2 separate measurements by a physician, the controlled use of BP medication, lack of using β‐blockers, no history of heart surgery, no known metabolic or inflammatory diseases, no alcohol, and no smoking, as well as no regular sports activities 6 months before the study 25 . Written consent was taken from all participants.…”

“…De acordo com Damorim et al (2017), o TR e/ou aeróbio se mostra eficiente na redução da PA, mas somente após a vigésima sessão de treinamento.…”
