“…On the other hand, the present results are different from the results of Scher et al [27] that verified a reduction of BP during the first 60 minutes and during 24 h after RE with low-intensity (40% of 1-RM), and Queiroz et al [28] that verified a reduction in SBP, DBP and MBP under clinical, but not ambulatory, conditions after low-intensity RE (50% of 1-RM). Moreover, previous studies with high-intensity RE observed no decrease of SBP or DBP during the recovery period [24,29,30], and some even have reported an increase in SBP [21].…”

BackgroundThe aim of the present study was to evaluate the acute effects of resistance exercise (RE) leading to failure and RE that was not to failure on 24 h blood pressure (BP) and heart rate variability (HRV) in sedentary normotensive adult women.MethodsTen women (33.2 ± 5.8 years; 159.3 ± 9.4 cm; 58.0 ±6.4 kg; body fat 28.4 ± 2.8%) randomly underwent three experimental sessions: control (40 minutes of seated rest), RE leading to failure with 3 sets of 10 repetitions maximum (10-RM), and RE not to failure at 60% of 10-RM with 3 sets of 10 repetitions. Immediately post session BP and HRV were measured for 24 h.ResultsRatings of perceived exertion and heart rate were higher during the 10-RM session when compared with 60% of 10-RM (6.4 ± 0.5 vs 3.5 ± 0.8 and 123.7 ± 13.9 vs 104.5 ± 7.3 bpm, respectively). The systolic, diastolic and mean BP decreased at 07:00 a.m. after the 10-RM session when compared with the control session (−9.0 ± 7.8 mmHg, -16.0 ± 12.9 mmHg and −14.3 ± 11.2 mmHg, respectively). The root mean square of the squared differences between R-R intervals decreased after both the 60% of 10-RM and 10-RM sessions compared with the control session.ConclusionsAn acute RE session leading to failure induced a higher drop of BP upon awakening, while both RE sessions reduced cardiac parasympathetic modulation. RE may be an interesting training strategy to acutely decrease BP in adult women.

“…Despite evidence regarding the occurrence of post-RE hypotension in older42,43 and hypertensive individuals,44,45 it is important to consider that the magnitude of BP changes in the postexercise period may directly be associated with higher pre-exercise BP levels,46 which was not the case in the present sample. Moreover, as suggested by West et al16 and observed in previous reports,47,48 anticipation of the upcoming stress test may prevent any significant BP reductions after exercise.…”

PurposeThis study aimed to investigate the effects of resistance exercise (RE) on autonomic control and blood pressure (BP) reactivity during mental stress (MS) in treated older hypertensive women.MethodsTen older hypertensive women (age =71.1±5.5 years; body mass index =24.2±3.9; mean BP [MBP] =85.4±3.5) underwent a protocol consisting of BP and heart rate variability (HRV) output assessments at baseline and during MS, and these measurements were taken before and 60 minutes after two bouts of RE (traditional and circuit). MS was induced through a computerized 3-minute Stroop color–word test before and 1 hour after each exercise session; BP was measured every minute during MS, and HRV was monitored as a measure of cardiac autonomic control.ResultsA significant effect of time on systolic BP (Δpre =17.4±12.8 versus Δpost =12.5±9.6; P=0.01), diastolic BP (Δpre =13.7±7.1 versus Δpost =8.8±4.5; P=0.01), and MBP (Δpre =14.0±7.7 versus Δpost =9.3±5.4; P<0.01) after RE was observed, with no differences between the two sessions. In addition, a significant effect of time on log-normalized low-frequency component of HRV (ms2; 5.3±0.8 pre-exercise MS versus 4.8±1.0 baseline value; P=0.023) was also observed, showing a significant change from baseline to MS before RE, but not after RE sessions. These results may be related to a lessened RE-mediated cardiac sympathetic activity during MS.ConclusionRE is an effective tool to reduce BP reactivity to MS, which could therefore be associated with an acute reduction in cardiovascular risk. This result presents relevant clinical implications, combining previous evidence that recommends this exercise modality as an important component of an exercise program designed for the older and hypertensive subjects.

“…Houve HPE após ambos os protocolos, embora somente a sessão com maior volume tenha reduzido a PAS após 24 horas. 15 Apesar da baixa intensidade, o treinamento de força em circuito favorece um maior número de repetições e maior tempo de tensão muscular, o que pode contribuir para uma maior resposta cardiovascular em virtude de maior estimulação nervosa muscular aferente, mediada por mecanismos associados aos controles mecanorreflexo e metaborreflexo.…”

“…2 Se por um lado a HA é apontada como uma morbidade preocupante, por outro a prática regular de exercício físico tem sido frequentemente recomendada como uma conduta fundamental na prevenção ou no tratamento não farmacológico dessa doença. 3 Diversos estudos demonstraram que uma única sessão de exercício aeróbio, 4-11 de força [12][13][14][15][16][17] ou concorrente (aeróbio e força) 18-21 seria capaz de reduzir a pressão arterial (PA) por algumas horas. Esse fenômeno, conhecido na literatura como hipotensão pós-exercício (HPE), consiste em níveis pressóricos observados no período de recuperação inferiores àqueles aferidos na situação pré-treino 22 ou mesmo àqueles verificados em um dia-controle sem realizar exercícios.…”

Volume 12, número 4, outubro-dezembro/2013 99 ResumoEvidências indicam que reduções crônicas na pressão arterial (PA) provocadas por exercício físico dependem, em grande medida, da capacidade de se induzir após cada sessão de treinamento o fenômeno da hipotensão pós-exercício (HPE). A presente revisão descreve artigos sobre contribuição do exercício aeróbio, de força e concorrente para a HPE, bem como apresenta possíveis mecanismos fisiológicos envolvidos. A ocorrência de HPE após diferentes tipos de exercício parece ser bem-aceita, tanto em indivíduos normotensos, quanto hipertensos. Contudo, a dose ótima de exercício aeróbio (ex.: relação entre intensidade, duração, modo de exercício e forma de execução) e de força (ex.: relação entre intensidade, volume e massa muscular envolvida) para maximizá-la permanece incerta. Dúvidas também persistem em relação aos diversos mecanismos fisiológicos envolvidos na HPE, que parecem ser diferentes no exercício aeróbio e de força. Destacam-se os mecanismos centrais e locais associados, respectivamente, à diminuição do débito cardíaco (DC) e resistência vascular periférica (RVP). Nesse sentido, os mecanismos envolvidos na HPE após o exercício aeróbio associar-se-iam tanto a fatores centrais (ex.: diminuição da atividade nervosa simpática), quanto a fatores periféricos (ex.: vasodilatação sustentada pela liberação de óxido nítrico, prostaglandinas e receptores da histamina). Na força, a HPE parece relacionarse, principalmente, com a diminuição do DC e a queda do volume sistólico, em resposta à menor perfusão miocárdica ocasionada pela maior compressão sequencial dos vasos.
