Breathing-strength training to lower blood pressure and help blood vessel health in postmenopausal women

Inspiratory muscle strength training for lowering blood pressure and improving endothelial function in postmenopausal women: comparison with "standard of care" aerobic exercise

NIH-funded research University of Colorado · NIH-11310122

This compares a short daily high-resistance breathing exercise to standard aerobic workouts to help lower blood pressure and improve blood vessel health in postmenopausal women.

What this research studies

If you join, you would be randomly assigned to do a brief daily inspiratory muscle workout with a small hand-held device or follow standard aerobic exercise recommendations, with the breathing program taking about five minutes a day. Researchers will measure your resting and 24-hour blood pressure, tests of blood vessel (endothelial) function, and blood markers of oxidative stress before and after the intervention. Some visits and testing will take place at the University of Colorado and staff will track how well participants stick with the program and any side effects.

Who could benefit from this research

Good fit: Ideal candidates are postmenopausal women with above-normal or high systolic blood pressure who are interested in a non-aerobic, home-based intervention and can attend clinic visits in Boulder, CO.

Not a fit: People who are not postmenopausal, men, those with well-controlled blood pressure already, or those unable to perform the breathing exercises or travel to the study site are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could offer a short, home-based breathing routine that meaningfully lowers systolic blood pressure and improves blood-vessel health for postmenopausal women.

How similar studies have performed: A prior small pilot trial showed promising reductions in resting and 24-hour systolic blood pressure with this breathing training, but larger trials are needed to confirm benefits.
