“Inhale, hold, exhale”–Paul Ebeling
Research has found that exercising for just 5 minutes daily using a breathing practice called Inspiratory Muscle Strength Training, or IMST, reduces blood pressure and improves some vascular health measures comparable to medication or aerobic exercise.
The study results provide strong evidence that this time-efficient exercise may play an important part in helping aging individuals prevent cardiovascular disease.
Just in the US, 65% of individuals older than 50 have blood pressure that is above normal, which places them at a higher risk of stroke or heart attack. But less than 40% meet the recommended guidelines for aerobic exercise.
Many lifestyle strategies that can help individuals maintain cardiovascular health as they grow older take a lot of time and effort and can be expensive and difficult for some individuals to access. IMST can be accomplished in 5 mins in the convenience of your own home while watching television.
IMST was developed in the 1980s to help severely ill patients with respiratory disease strengthen their diaphragm and other breathing muscles, and involves vigorous inhaling through a resistance-providing hand-held device.
When initially prescribing it for breathing disorders, physicians recommended a daily 30-min schedule at low resistance. But in the past few yrs, the researchers have been testing whether 30 inhalations daily at high resistance, 6 days every wk could also provide cognitive and cardiovascular improvements.
The researchers recruited 36 individuals between the ages of 50 and 79 who were otherwise healthy with systolic blood pressure that was above normal. Half of them performed IMST at high resistance for 6 wks and half of them performed a placebo reduced resistance protocol.
The IMST group’s systolic blood pressure dropped 9 points on average after 6 wks, a decrease which generally surpasses that achieved by walking 30 mins every, day 5 days every week. That decrease is also comparable to the effects of some medications that reduce blood pressure.
Even 6 wks after the participants stopped practicing IMST, they maintained almost all of that improvement, which indicates that the benefits could also be longer lasting compared to traditional exercise programs.
The IMST group also experienced an improvement of 45% in vascular endothelial function, as well as an increase in nitric oxide levels, a molecule important for dilating arteries and preventing the buildup of plaque. Levels of nitric oxide naturally diminish with age. Oxidative stress and inflammation markers, which can also boost the risk of heart attack, were also significantly reduced after individuals practiced IMST.
Have a healthy, prosperous week, breathe and Keep the Faith!
