It's well known that weightlifting can strengthen our biceps and quads. Now, there's accumulating evidence that strengthening the muscles we use to breathe is beneficial too. New research shows that a daily dose of muscle training for the diaphragm and other breathing muscles helps promote heart health and reduces high blood pressure.
"The muscles we use to breathe atrophy, just like the rest of our muscles tend to do as we get older," explains researcher Daniel Craighead, an integrative physiologist at the University of Colorado Boulder. To test what happens when these muscles are given a good workout, he and his colleagues recruited healthy volunteers ages 18 to 82 to try a daily five-minute technique using a resistance-breathing training device called PowerBreathe. The hand-held machine — one of several on the market — looks like an inhaler. When people breathe into it, the device provides resistance, making it harder to inhale.

..."So we suspect that IMST consisting of only 30 breaths per day would be very helpful in endurance exercise events," Craighead says. It's a technique that athletes could add to their training regimens. Craighead, whose personal marathon best is 2 hours, 21 minutes, says he has incorporated IMST as part of his own training.
The technique is not intended to replace exercise, he cautions, or to replace medication for people whose blood pressure is so elevated that they're at high risk of having a heart attack or stroke. Instead, Craighead says, "it would be a good additive intervention for people who are doing other healthy lifestyle approaches already."
This is the way Theresa D. Hernandez, 61, sees the breathing exercises. She lives in Boulder, has a family history of high blood pressure and participated in the Colorado research. When the study began, she had blood pressure readings near the threshold at which doctors recommend medications.
"It was a surprise that something as simple could be so profound in terms of its impact," says Hernandez of the six weeks of breathing exercises. "It took my blood pressure to under the threshold so that I would not need to take medication," she says.
Her blood pressure dropped significantly, and she says she plans to stick with it — five minutes every day."
