What this Trial Is About
Researchers are evaluating the effects of respiratory exercises on cardiovascular health, particularly focusing on cardiac vagal modulation and pulse wave velocity in normotensive postmenopausal women. This study compares two popular respiratory exercise methods: Inspiratory Muscle Training (IMT) and the newly developed CardioBreath® App. The goal is to validate the app as a tool for respiratory exercise and understand its impact on autonomic nervous system balance and vascular function. Participants will be randomly assigned to one of three groups: an active IMT group using a PowerBreath device with a 30% inspiratory load, a placebo IMT group using the same device without load, or a CardioBreath® App group using a guided app for breathing exercises. Each group will perform exercises at home for 10 minutes, five days a week, over five weeks. Weekly laboratory visits will allow for adjustments of the inspiratory load or respiratory rate based on individual performance. During the study, participants will undergo assessments including blood pressure, heart rate variability, pulse wave velocity, and central arterial pressure using specialized devices. These measures will evaluate autonomic and vascular responses before and after the intervention. Exercise adherence will be tracked through audio recordings for IMT groups and progress graphics for the app group. The study aims to provide a detailed analysis of cardiovascular autonomic control and vascular stiffness changes over the five-week period.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 5 weeks
Participants perform respiratory exercises at home using either the PowerBreath device or the CardioBreath App for five days per week, 10 minutes each day. Weekly visits are held to adjust device load or respiratory rates as needed.
Weekly visits for load or rate adjustment
Duration - 1 day
Participants are re-evaluated for cardiovascular autonomic control and pulse wave velocity to assess the effects of the respiratory exercises.
