Methods: Twenty-six non-obese postmenopausal women were divided into two groups: the hypertensive group (HT; n = 13; 58.9 ± 3.9 years; and BMI of 27.7 ± 4.6 kg/m 2) or the normotensive group (NT; n = 13; 52.7 ± 5.2 years; and BMI of 26.9 ± 2.9 kg/m 2). They performed 30 sessions of combined exercises over 10 weeks: 45 min per session, three times a week. Resting saliva samples were collected after an overnight fast to evaluate salivary nitrite levels and oxidative stress markers before and after training. Results: Two-way ANOVA showed that there was no difference in the responses over time between the hypertensive and normotensive groups in catalase, superoxide dismutase salivary activity, total antioxidant capacity, or lipid peroxidation. However, superoxide dismutase activity (ΔHT-0.87 ± 14.53 SOD/mg protein; ΔNT: 7.13 ± 9.39 SOD/mg protein; p < 0.01) and nitrite levels (ΔHT 10.32 ± 60.83 mM; ΔNT 101.92 ± 149.57 mM; p = 0.03) were higher overall in the hypertensive group compared to the normotensive group. Moreover, salivary nitrite levels increased over time (p = 0.04) in both groups. Conclusion: 10 weeks of combined exercise training did not change salivary oxidative stress markers in either normotensive or hypertensive postmenopausal women, although, after exercise training, nitrite levels increased in both groups, even with higher baseline salivary nitrite levels in hypertensive women. Thus, recurrent exercise seems to be a safe strategy after menopause from the standpoint of oxidative stress, regardless of the presence of hypertension.

Fourteen hypertensive postmenopausal women monitored BP at rest and during 24 h by ambulatory BP monitoring in a control day without exercise performance a pretraining (baseline), after an acute exercise session (acute), and after a chronic exercise training for 10 weeks (chronic). After exercise training, systolic BP (SBP, Δ = −150 mmHg.24 h), diastolic BP (DBP, Δ = −96 mmHg.24 h), and mean BP (MBP, Δ = −95 mmHg.24 h) area under the curve were smaller than baseline measurements (P < 0.05) with no difference between acute and baseline measurements. The SBP (ΔSD24 = −2, ΔSDdn = −1.7, and ΔARV24 = −1.9 mmHg), DBP (ΔSD24 = −0.9, ΔSDdn = −0.8, and ΔARV24 = −0.9 mmHg), and MBP (ΔSD24 = −1.5, ΔSDdn = −1.3, and ΔARV24 = −1.2 mmHg) variability reduced in acute session in relation to baseline, with no chronic effects. There are moderate correlations between acute and chronic responses in wake SBP, sleep DBP, and SD24. In conclusion, combined exercise reduces ambulatory BP chronically but not acutely. In contrast, BPV decreases after an acute session but not chronically. Awake SBP, sleep DBP, and SD24indices are promising candidates to predict individual cardiovascular responses to exercise.

The aim of this study was to investigate whether there are additive effects of isoflavone supplementation when associated with combined aerobic and resistance exercise on resting and ambulatory blood pressure monitoring (ABPM) and in blood pressure variability (BPV). Thirty-one non-obese postmenopausal women were randomly allocated into two groups: placebo and exercise (Placebo n = 19); and isoflavone supplementation (100 mg/day) and exercise (isoflavone n = 19). ABPM and BPV were evaluated before and after 10 weeks of moderate combined (aerobic and resistance) exercise training. Generalized Estimating Equation (GEE) with Bonferroni correction and intention-to-treat analysis was used to compare the effects of interventions on resting BP, ABPM and BPV. Combined exercise training decreased resting systolic (SBP) and diastolic blood pressure (D...
