“…These data are similar to other studies, which observed PEH after resistance and endurance exercises 8,10–14,19,21. To the best of our knowledge, this is the first study designed to investigate the acute effects of PT on hemodynamic parameters of older women, thereby limiting data discussion.…”

“…Recently, Gerage et al12 evaluated the blood pressure levels after an acute session of sub-maximal resistance exercise in older women and found a moderate decrease (−5 mmHg) in SBP 1 hour after the end of the exercise. Furthermore, data in the literature have demonstrated decreased cardiac autonomic modulation after RT protocols, which inhibits the decrease in HR after exercise 10,14,36. Therefore, dissimilar results between protocols can be explained by differences in the variables of RT (volume and number of exercises).…”

“…These findings suggest that the chronic effects of RT can be a result of a sum of the acute effects 9. However, the optimum protocol of RT able to elicit PEH is still unknown, and most studies have been indicating beneficial results from traditional moderate-intensity RT 10–12,14…”

PurposeThe purpose of this study was to compare the acute effects of resistance training (RT) and power training (PT) on the hemodynamic parameters and nitric oxide (NO) bioavailability of older women.Materials and methodsA randomized experimental design was used in this study. Twenty-one older women (age: 67.1±4.6 years; body mass index: 28.03±4.9 kg/m2; systolic blood pressure: 135.1±21.1 mmHg) were recruited to participate in this study. Volunteers were randomly allocated into PT, RT, and control session (CS) groups. The PT and RT groups underwent a single session of physical exercise equalized by training volume, characterized by 3 sets of 8–10 repetitions in 8 different exercises. However, RT group performed exercise at a higher intensity (difficult) than PT (moderate) group. On the other hand, concentric contractions were faster in PT group than in RT group. Hemodynamic parameters and saliva samples (for NO quantification) were collected before and during an hour after exercise completion.ResultsResults demonstrated post-exercise hypotension during 35 minutes in the PT when compared to rest period (P=0.001). In turn, RT showed decreased heart rate and double product (P<0.001) during the whole evaluation period after exercise completion compared with the rest period. NO levels increased in the PT and RT during the whole evaluation period in relation to rest period. However, there were no differences between PT, RT, and CS regarding hemodynamic and NO evaluations.ConclusionData indicate that an acute session of power and resistance exercise can be effective to cause beneficial changes on hemodynamic parameters and NO levels in older women.

“…This suggests that load might not influence sympathovagal balance. Other variables such as total work volume and time under tension might be related to the sympathetic activation system and consequent increase in cardiovascular risk, as previously suggested [23, 24]. …”

“…However, its relationship with the practice of RT in people with hypertension is not well understood. Some authors, such as Lima et al [23] and Rezk et al [24], suggest that RT with heavier loads leads to an increase in sympathetic activation due to the greater mechanical overload in the vascular system [25], with consequent decrease in HRV. However, our results showed that HRV components that indicate sympathetic activation were greater after RT performed at lighter loads and a higher repetition range (15RM).…”

Acute effects of different resistance training loads on cardiac autonomic modulation in hypertensive postmenopausal women

et al. 2018

BackgroundIndividuals with arterial hypertension often have an autonomic nervous system (ANS) imbalance with predominance of sympathetic ANS. This predominance can lead to injury of several organs affecting its functioning. There is evidence that performing high intensity resistance training (RT) with heavier loads and a lower number of repetitions results in lower cardiovascular stress when compared with lighter loads and a higher number of repetitions. However, the effects of different protocols of RT in autonomic modulation are not known. Therefore, the aim of the study was to analyze and compare the effects of different protocols of high intensity of effort RT on autonomic cardiac modulation of hypertensive women.MethodsA randomized crossover design clinical trial was conducted with 15 postmenopausal hypertensive women who underwent a control session and two high intensity RT protocols involving 6 and 15 repetition maximum (RM). Heart rate variability (HRV), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and double product (DP) were collected pre, immediately post, 1 h post, and 24 h post each protocol. Repeated-measures ANOVA were used.ResultsSBP was higher for 6RM than control immediately after session (p < 0.05). There were no differences for DBP among protocols (p ≥ 0.05). HR was higher for 15RM than 6RM and control immediately after and 1 h after session (p ≤ 0.05). DP values for 15RM were significantly higher than 6RM and control immediately after the session and remained higher than control 1 h after session (p ≤ 0.05). The indices that compose HRV (rMSSD) were lower after 15RM than 6RM and control (p ≥ 0.05). The parameters of parasympathetic activity (HF) were decreased and sympathetic (LF) activity was increased for 15RM when compared to the 6RM and control session immediately after the exercise session (p ≤ 0.05).ConclusionPerforming high intensity RT with lower loads and a higher number of repetitions seems to promote acute increases in sympathetic ANS activity, which may be related to cardiovascular stress. On the other hand, heavier load and lower repetition RT did not significantly impact upon autonomic modulation when compared to a control session.

Abstract: Background: Cardiac sympathovagal balance is altered after resistance exercise. However, the impact of the characteristics of resistance training in this response remains unclear.
