Minimal Dose of Resistance Exercise Required to Induce Immediate Hypotension Effect in Older Adults with Hypertension: Randomized Cross-Over Controlled Trial.

ABSTRACT: To determine the optimal exercise volume to generate a hypotension response after the execution of a single strength exercise in elderly subjects with hypertension (HT), a randomized crossover design was performed. A total of 19 elderly subjects with HT performed one control session and three experimental sessions of resistance training with different volumes in a randomized order: three, six, and nine sets of 20 repetitions maximum (RM) of a single elbow flexion exercise with elastic bands. The systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean heart rate (MHR) were tested at the beginning and immediately afterwards, at 30 and 60 min, and at 4, 5, and 6 h after the resistance exercise. The results show that the volumes of six and nine sets of 20 RM obtained statistically significant differences in the SBP at 30 and 60 min post-exercise (p < 0.05); in the DBP at 30 min after exercise (p < 0.05); and in the MHR immediately after exercise at 30 and 60 min (p < 0.05), compared to a control session. A single resistance exercise with a minimum volume of six sets of 20 RM generated an acute post-exercise antihypertensive response that was maintained for 60 min in elderly people with controlled HT.

Project description:BackgroundThe prevalence of hypertension increases with age, and older people with this condition are at increased risk of developing orthostatic hypotension (OH) due to age-related changes in blood pressure regulation mechanisms as well as prescribed medications. OH increases the risk of falls, often with subsequent fractures as well as other morbidity and even mortality. The prevalence and characteristics of OH in older people with hypertension in Low-Income Countries have not been well characterized. This study aims to determine the prevalence of OH and associated factors among older people with hypertension in northern Ethiopia.MethodA hospital-based cross-sectional study was conducted using a convenience sample of patients aged 60 years and older with hypertension receiving pharmacotherapy and followed up at the University of Gondar Hospital, Ethiopia. Blood pressure (BP) was measured in the supine position, and after 3 min of standing; the level of BP drop (> 20/10) was used to define measured OH. Data regarding symptoms of OH were also collected using the Orthostatic Hypotension Questionnaire (OHQ). The data were entered into Microsoft Excel version 2016 and exported to SPSS version 20 for statistical analysis. Logistic regression analysis was conducted to assess the factors associated with OH.ResultsA total of 240 participants were included, with a mean age of 68.8 ± 7.1 years. The prevalence of OH was 23.8% (CI: 21.5%, 26.1%). Of the medications used, calcium channel blocker (CCBs) treatment was strongly associated with OH (AOR = 2.03[95%CI = 1.08-3.8]). Two-thirds (61.4%) of participants with measured OH experienced relevant symptoms of OH.ConclusionThere was a high prevalence of OH among older patients with hypertension attending a tertiary care hospital in Gondar, with one in four affected. The use of CCBs was identified as an independent risk factor for OH. Most patients with OH experienced relevant symptoms, so monitoring this condition in this group may help prevent adverse consequences.

Project description:One single bout of exercise can be associated with positive effects on cognition, due to physiological changes associated with muscular activity, increased arousal, and training of cognitive skills during exercise. While the positive effects of life-long physical activity on cognitive ageing are well demonstrated, it is not well established whether one bout of exercise is sufficient to register such benefits in older adults. The aim of this study was to test the effect of one bout of exercise on two cognitive processes essential to daily life and known to decline with ageing: audio-visual perception and immediate memory. Fifty-eight older adults took part in a quasi-experimental design study and were divided into three groups based on their habitual activity (open skill exercise (mean age = 69.65, SD = 5.64), closed skill exercise, N = 18, 94% female; sedentary activity-control group, N = 21, 62% female). They were then tested before and after their activity (duration between 60 and 80 minutes). Results showed improvement in sensitivity in audio-visual perception in the open skill group and improvements in one of the measures of immediate memory in both exercise groups, after controlling for baseline differences including global cognition and health. These findings indicate that immediate benefits for cross-modal perception and memory can be obtained after open skill exercise. However, improvements after closed skill exercise may be limited to memory benefits. Perceptual benefits are likely to be associated with arousal, while memory benefits may be due to the training effects provided by task requirements during exercise. The respective role of qualitative and quantitative differences between these activities in terms of immediate cognitive benefits should be further investigated. Importantly, the present results present the first evidence for a modulation of cross-modal perception by exercise, providing a plausible avenue for rehabilitation of cross-modal perception deficits, which are emerging as a significant contributor to functional decline in ageing.
