Resistance exercise training is more effective than interval aerobic training in reducing blood pressure during sleep in hypertensive elderly patients. J Strength Cond Res 32(7): 2085-2090, 2018-An appropriate fall in blood pressure (BP) during sleep is known to be related to a lower cardiovascular risk. The objective of this study was to compare the effect of different types of training on hypertensive elderly patients under treatment in terms of pressure variability assessed by the nocturnal decline in BP. Hypertensive elderly subjects under pharmacological treatment were randomly assigned to the following groups: 12 weeks of continuous aerobic training, interval aerobic training (IA), resistance training (R), or control (C). All subjects underwent ambulatory BP monitoring before and 24 hours after the last exercise session. The results were assessed using the mixed effects model. A greater nocturnal decline in diastolic BP compared with the wakefulness period was observed in R in comparison with C (11.0 ± 4.1 vs. 6.0 ± 5.7 mm Hg and p = 0.01) and with IA (11.0 ± 4. vs. 6.5 ± 5.1 mm Hg and p = 0.02). No fall in BP during a 24-hour period was observed in training groups compared with C, perhaps because the subjects were mostly nondippers, for whom the effect of training on BP is found to be lower. In conclusion, resistance training promoted a greater nocturnal fall in BP among hypertensive elderly subjects under treatment compared with IA subjects.
BackgroundSeasoning is one of the recommended strategies to reduce salt in foods. However, only a few studies have studied salt preference changes using seasoning.ObjectivesThe aim of this study was to compare preference for salty bread, and if seasoning can change preference in hypertensive and normotensive, young and older outpatients.MethodsOutpatients (n = 118) were classified in four groups: older hypertensive subjects (OH) (n = 32), young hypertensive (YH) (n = 25); older normotensive individuals (ON) (n = 28), and young normotensive (YN) (n = 33). First, volunteers random tasted bread samples with three different salt concentrations. After two weeks, they tasted the same types of breads, with seasoning added in all. Blood pressure (BP), 24-hour urinary sodium and potassium excretion (UNaV, UKV) were measured twice. Analysis: Fisher exact test, McNamer’s test and ANCOVA. Statistical significance: p < 0.05.ResultsSystolic BP, UNaV, and UKV were greater in HO and HY and they had a higher preference for saltier samples than normotensive groups (HO: 71.9%, HY: 56% vs. NO: 25%, NY; 6%, p<0.01). With oregano, hypertensive individuals preferred smaller concentrations of salt, with reduced choice for saltier samples (HO: 71.9% to 21.9%, and HY: 56% to 16%, p = 0.02), NO preferred the lowest salt concentration sample (53.6% vs. 14.3%, p < 0.01), and NY further increased the preference for the lowest one (63.6% vs. 39.4%, p = 0.03).ConclusionsOlder and younger hypertensive individuals prefer and consume more salt than normotensive ones, and the seasoned bread induced all groups to choose food with less salt. Salt preference is linked to hypertension and not to aging in outpatients.
The aim of this study was to evaluate the preference for salt in hypertensive and normotensive older individuals. Hypertensive (group 1: n=32, aged 73.7±6.3 years) or normotensive patients (group 2: n=26, aged 71.5±8.0 years) were submitted to a test to determine their preference for bread samples with different salt concentrations: 1.5%, 2.0% (usual concentration), and 2.7%, and were reevaluated 2 weeks later using the same salt concentrations, but with the addition of oregano. Twenty‐four–hour urinary sodium excretion (UNaV), blood pressure (BP), and body mass index (BMI) were obtained. Systolic BP, BMI, and UNaV were higher in group 1. In the first analysis, group 1 showed greater preference for the saltiest sample (P=.001). Comparing the first evaluation and the second, a greater preference for less salty samples was observed in both groups (P<.01). Hypertensive older patients consumed more salt and showed a greater salt preference than the normotensive patients. The use of the spice reduced the preference for salt in both groups.
