Clinic and Ambulatory Blood Pressure Responses After Resistance Exercise

Abstract

This study investigated clinic and ambulatory blood pressure (BP) responses after a single bout of low-intensity resistance exercise in normotensive subjects. Fifteen healthy subjects underwent 2 experimental sessions: control-40 minutes of seated rest, and exercise-6 resistance exercises, with 3 sets of as many repetitions as possible until moderate fatigue, with an intensity of 50% of 1-repetition maximum (1RM). Before and for 60 minutes after interventions, clinic BP was measured by auscultatory and oscillometric methods. Postintervention ambulatory BP levels were also measured for 24 hours. In comparison with preintervention values, clinic systolic BP, as measured by the auscultatory method, did not change in the control group, but it decreased after exercise (-3.7 +/- 1.6 mm Hg, p < 0.05). Diastolic and mean BP levels increased after intervention in the control group (+3.4 +/- 1.0 and +3.0 +/- 0.8 mm Hg, respectively, p < 0.05) and decreased in the exercise group (-3.6 +/- 1.7 and -3.4 +/- 1.4 mm Hg, respectively, p < 0.05). Systolic and mean oscillometric BP levels did not change after interventions either in the control or exercise sessions, whereas diastolic BP increased after intervention in the control group (+5.0 +/- 1.7 mm Hg, p < 0.05) but not change after exercise. Ambulatory BP behaviors after interventions were similar in the control and exercise sessions. Significant and positive correlations were observed between preexercise values and postexercise clinic and ambulatory BP decreases. In conclusion, in the whole sample, a single bout of low-intensity resistance exercise decreased postexercise BP under clinic, but not ambulatory, conditions. However, considering individual responses, postexercise clinic and ambulatory hypotensive effects were greater in subjects with higher preexercise BP levels.

Hypotension and heart rate variability after resistance exercise performed maximal and submaximal order

“…O segundo aspecto é referente aos breves momentos em que essas quedas foram exibidas que por sua brevidade poderiam ser negligenciáveis, porém, se pensarmos em tais efeitos ocorrendo em momentos do dia onde a PA pode estar naturalmente mais elevada, essas ligeiras reduções podem ter importantes implicações clínicas (ACSM, 2004). Deve-se ainda considerar que o grupo amostral foi composto por normotensos, e já é bem caracterizado pela literatura que quedas da pressão arterial pós-esforço em grupos hipertensos, são mais significativas (Queiroz, Gagliardi, Forjaz, & Rezk, 2009). Portanto, pequenos volumes de treinamento não devem ser desprezados, e sim investigados em outras populações para que se possa ter conhecimento, se as tendências aqui descritas, em grupos hipertensos tomariam maior robustez.…”

Effects of aerobic and resistance exercise intensities on 24-hours blood pressure in normotensive women

“…(Melo, Alencar Filho, Tinucci, Mion Jr, & Forjaz, 2006) reported that PEH lasted 10 h in middle-aged hypertensive women after a resistance exercise session. Conversely, other studies (Queiroz, Gagliardi, Forjaz, & Rezk, 2009;Roltsch, Mendez, Wilund, & Hagberg, 2001) did not observe PEH in normotensive young women. Our study is one of the first to show that resistance exercise, even at low intensities, can induce PEH for up to 24 h in middleaged, normotensive women.…”

Resistance exercise performed with repetitions until failure affects nocturnal blood pressure decreases in hypertensive women

“…A number of factors may explain this. The patients' levels of BP prior to the intervention were well controlled and the increase in postexercise hypotension tends to be greater in subjects with higher resting BP (Queiroz, Gagliardi, Forjaz, & Rezk, 2009). In fact, the mean systolic BP before the experimental sessions ranged from 116 to 120 mmHg and approximately 92% of the patients had BP levels below 140/90 mmHg.…”
