A five-minute workout that scientists call “strength training for your breathing muscles” is proving to lower blood pressure as well as or even better than traditional exercise and prescription drugs. Researchers from the University of Colorado-Boulder say this groundbreaking exercise makes use of a hand-held device which provides resistance as the user breathes. Simply put, as you suck in air, the tube tries to suck it back in.
Researchers call this technique High-Resistance Inspiratory Muscle Strength Training (IMST). Although doctors in the past have recommended patients with breathing disorders use these devices at low power for about 30 minutes, the new study finds a five-minute, high-intensity burst can improve cardiovascular health among older adults.
Results show participants in the IMST group saw their systolic blood pressure fall by an average of nine points. That kind of improvement, researchers say, is generally better than what high blood pressure patients see from walking 30 minutes a day five days a week. The study finds the IMST results are even on par with certain blood pressure-lowering drugs prescribed to patients.
