Improving blood pressure and vascular function in older adults with sleep-disordered breathing through muscle training.

Official title: Time-efficient inspiratory muscle strength training for improving blood pressure and vascular function in older adults with sleep-disordered breathing

Funded at University of Arizona · NIH-11081806 · Data updated 2026-11-12

This study is testing a quick and easy breathing exercise that takes just 5 minutes a day for six weeks to see if it can help lower blood pressure and improve heart health in older adults with sleep apnea.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults diagnosed with obstructive sleep apnea who may have difficulty adhering to traditional exercise programs.

Less likely to help

Patients without sleep-disordered breathing or those who are not older adults may not receive benefit from this research.

What this research studies

This research investigates a time-efficient method of inspiratory muscle strength training (IMST) aimed at lowering blood pressure and improving vascular function in older adults suffering from obstructive sleep apnea (OSA). Participants will engage in a simple training regimen that requires only about 5 minutes a day for six weeks. The study focuses on how this training can reduce resting systolic blood pressure and improve cardiovascular health, particularly in a population that often struggles with traditional exercise regimens. By targeting the sympathetic nervous system's activity, the research aims to provide a novel approach to managing hypertension in older adults with sleep-related breathing disorders.

Why it matters

Potential benefit: If successful, this research could provide a simple and effective intervention for lowering blood pressure and enhancing cardiovascular health in older adults with sleep-disordered breathing.

How similar studies have gone: Preliminary studies have shown promising results with similar approaches, indicating potential for significant improvements in blood pressure and vascular function.
