Acute and Chronic Effects of Resistance Training Intensity on Cardiovascular Parameters of Postmenopausal Women With Systemic Arterial Hypertension

What this Trial Is About

Researchers are studying how different intensities of resistance training (RT) affect cardiovascular health in postmenopausal women with systemic arterial hypertension (SAH). They aim to find out if training at 60% or 80% of one repetition maximum (1RM) influences blood pressure, heart rate and its variability, endothelial function, nitric oxide levels, mood, and perceived effort. The study includes both an acute experiment and a chronic experiment to assess these effects over time. In the acute experiment, participants perform two RT sessions in random order, one at 60% 1RM and another at 80% 1RM. Blood pressure, heart rate, and heart rate variability are measured before, immediately after, and for one hour post-exercise. Mood and perceived exertion are also recorded. In the chronic experiment, participants are randomly assigned to train at either 60% or 80% 1RM for 10 weeks, with two sessions per week. Assessments occur before, during, and after this period, including measures of endothelial function, heart rate variability, and salivary nitric oxide. Participants will attend multiple sessions over about 10 weeks and undergo evaluations involving blood pressure, heart rate, mood, perceived exertion, endothelial function, and nitric oxide levels. The study tracks blood pressure changes up to one year and uses questionnaires and physiological tests to monitor cardiovascular responses. The research evaluates both immediate and long-term effects of RT intensity on cardiovascular health and related factors in this specific group of women.
