The University of Colorado Boulder chooses our POWERbreathe K-Series IMT device as part of their major clinical trial into the effects of Inspiratory Muscle Strength Training (IMST) on lowering blood pressure, reducing heart attack risk, as well as, boosting cognitive and physical performance. During the trial, they find significant drops in blood pressure and improvements in large-artery function among trial participants who perform POWERbreathe IMST.
