Inclusion criteria
Inclusion criteria: Female; 60 years of age or older; have been diagnosed with hypertension by means of a medical report or self-report that they have hypertension and be using antihypertensive medication prescribed by a physician; be using antihypertensive medication with a dose maintained for the last 6 months; not have secondary arterial hypertension and/or target organ damage; not use medications that directly affect cardiac autonomic regulation (e.g. beta-blockers and non-dihydropyridine calcium channel inhibitors antidepressants); not have other cardiovascular diseases, in addition to arterial hypertension; not have grade II or higher obesity; not have diabetes with complications or use of insulin; and not have orthopedic changes that make it impossible to practice the isometric resistance training in question; not be a smoker or have smoked in the last year; not undergoing hormone therapy
Exclusion criteria
Exclusion criteria: Presenting resting blood pressure above 160 mmHg for systolic blood pressure and/or 100 mmHg for diastolic blood pressure on the day of the exercise in two consecutive reschedulings; impossibility of continuing the collection for health reasons or any other reason raised by the participant; deciding to leave the study voluntarily; impossibility of carrying out the experimental sessions (intervention and control) with a time interval of less than 3 weeks
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the systolic blood pressure response after the proposed interventions; a reduction in this variable is expected, which constitutes the primary outcome of the study. Systolic blood pressure will be measured using an OMRON oscillometric blood pressure monitor, following international recommendations for standardized assessment. The mean values obtained before and after each intervention will be examined to determine whether a significant reduction in systolic blood pressure has occurred. | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate diastolic blood pressure, mean arterial pressure, ambulatory blood pressure (systolic and diastolic), blood pressure variability, heart rate variability, and salivary nitrite concentration after the interventions, with the expectation of finding improvements in hemodynamic and autonomic parameters. Diastolic blood pressure and mean arterial pressure will be assessed using an OMRON oscillometric blood pressure monitor; ambulatory blood pressure and blood pressure variability will be measured using the Cardios Ambulatory Blood Pressure Monitor; heart rate variability will be evaluated using a Polar chest strap; and salivary nitrite concentration will be determined through saliva collection and laboratory analysis. The mean values of these parameters obtained before and after each intervention will be examined to determine whether reductions in blood pressure, changes in variability indices, and alterations in salivary nitrite concentration occurred, thereby indicating a significant effect on these secondary outcomes. | — |
