The influence of physical activity on the arterial blood pressure of the elderly : a systematic review
Doroteja Rančić, Tamara Ilić, Stefan Stojanović, 2023, review article

Abstract: Purpose: The aim of this review was to determine the influence of physical activity on the arterial blood pressure of the elderly through a review of previous research.Methods: The search was performed on the Web of Science, Google Scholar and PubMed databases. The first search identified 1112 articles. In the initial assessment carried out in accordance with the inclusion and exclusion criteria, 15 articles were found suitable and were included in the study, while 1097 studies were excluded. The search was limited to articles published in period of 2002–2022.Results: After the applied exercise programs and evaluation at the final measure-ments, the mean values of systolic blood pressure, on the total sample, were 131 mmHg, while the values of diastolic blood pressure were 77 mmHg, which indicates that physi-cal activity (regardless of whether swimming, walking, yoga, resistance training, high interval training, Tai Chi) have a positive effect on the arterial blood pressure of the elderly.Conclusion: All studies, except one, showed a positive influence of physical activity on the arterial blood pressure of elderly people. In this regard, it can be concluded that physical activity, regardless of the type of activity, has a positive effect on the arterial blood pressure of the elderly, in the form of a reduction in blood pressure values.

A randomized crossover trial on the acute cardiovascular demands during flywheel exercise
Damir Zubac, Vladimir Ivančev, Zoran Valić, Rado Pišot, Cécil J. W. Meulenberg, Irhad Trozic, Nandu Goswami, Boštjan Šimunič, 2021, original scientific article

Abstract: In a randomized crossover trial, we examined whether age plays a role in the mean arterial pressure (MAP) response during a vigorous flywheel exercise of varying load. We hypothesized that the magnitude of increase in the MAP during the flywheel exercise would increase in proportion to advancing age, thereby imposing a significant challenge to the cardiovascular system. A total of 30 participants of both sexes (age range from 20%55 y, 37% women) underwent a detailed medical examination, and their maximal oxygen uptake was determined. They performed a squat exercise (2 sets % 7 repetitions) on a flywheel ergometer at three randomly assigned moments of inertia set at 0.025, 0.05, and 0.075 kg m2, while the cardiovascular response was continuously recorded via a Task force monitor. Compared to the resting values, robust rises in the MAP were observed during all three flywheel loads, reaching the highest value of 179 % 4 mmHg (p = 0.001) during the highest load. In parallel, the cardiac index (cardiac output normalized by the body surface area) was two-fold greater during all the flywheel loads compared to rest, and at a high load, exclusively, the total peripheral resistance increased by 11% (p = 0.001). The rise in heart rate compensated for a load-dependent drop in the stroke index (stroke volume normalized by the body surface area). In our study population, no correlations were observed between the relative increase in the MAP and the participants% age for the three flywheel loads. The present findings suggest that the larger moments of inertia impose a substantial burden to the cardiovascular system, without apparent associated age-differences of the relative magnitude of MAP rise throughout the exercise.

Absence of adverse effects of tiotropium/ olodaterol compared with the monocomponents on long-term heart rate and blood pressure in patients with moderate-to-very-severe COPD
Stefan Andreas, Lorcan Mcgarvey, Ulrich Bothner, Matthias Trampisch, Alberto De La Hoz, Matjaž Fležar, Roland Buhl, Peter Alter, 2020, original scientific article

Abstract: Introduction: Long-acting [beta]2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) are established maintenance bronchodilator treatments for chronic obstructive pulmonary disease (COPD) with the potential to increase heart rate (HR) and impact blood pressure (BP). While previous studies indicate that HR and BP are not negatively influenced by tiotropium or olodaterol monotherapy, the effect of tiotropium/olodaterol has not been evaluated. We report a post hoc analysis of the effect of dual bronchodilation with tiotropium/olodaterol versus monocomponents on HR and BP in patients with moderate-to-very-severe COPD included in the large TONADO© study. Methods: The TONADO© trials (1237.5 [NCT01431274] and 1237.6 [NCT01431287]) were two replicate, randomized, double-blind, parallel-group, 52-week, Phase III trials that compared tiotropium/olodaterol (5/5 [micro]g and 2.5/5 [micro]g) with tiotropium (5 [micro]g and 2.5 [micro]g) and olodaterol (5 [micro]g) in patients with moderate-to-very-severe COPD. Patients with cardiovascular comorbidities were included. Changes in HR and systolic/diastolic BP were measured before and after dosing with the study medication at each visit (baseline, Week 12, Week 24 and Week 52). Results: Overall, 3,100 patients were included in this analysis. Over 52 weeks, small changes from baseline in mean HR (<2 beats per minute [bpm]) and small changes from pre- to post-dose (<1 bpm) were evident at different time points. There was a non-significant increase from baseline in mean diastolic and systolic BP (<2 mmHg) observed over 52 weeks of treatment. The short-term (1 hour pre- to 1 hour post-dose) mean changes in systolic and diastolic BP over 52 weeks in the tiotropium/olodaterol 5/5 [micro]g group were comparable with those observed for the monocomponents at all time points. Conclusion: There were no differences in HR or BP among patients on tiotropium/olodaterol when compared with monocomponents. This supports the already demonstrated cardiovascular safety profile of tiotropium/olodaterol as long-acting maintenance bronchodilator treatment for COPD, including patients with cardiovascular comorbidities.
