The University of Colorado Boulder is using the POWERbreathe K-Series in their independent research. They are investigating the effects of just 30 breaths of inspiratory muscle strength training (IMST). Specifically, they are looking to see if it could lower blood pressure and reduce heart attack risk. They are also investigating whether it could help you think more clearly and boost sports performance.
Lower blood pressure
One of the key findings of the research so far is that 30 breaths of IMST (about five minutes) will lower blood pressure. Crucially, with about half the tests completed, researchers report significant drops in blood pressure and improvements in large-artery function. In fact, their findings show that about 5-minutes of IMST lowers blood pressure as much as aerobic exercise and more than some medications.
Other preliminary findings
The research findings also suggest that just 5-minutes of IMST may also boost cognitive function. Furthermore, their findings show that it may also improve fitness and increase sports performance. In fact, these improvements are already proven in previous research studies. However, this study reiterates such findings.
With the help of the university’s new National Institute on Ageing grant, researchers are launching a clinical trial.
Research subjects will either be a part of a sham group (using low/no IMST) or the IMST group. The IMST group will perform 30 breaths of inspiratory muscle strength training (taking approximately 5-minutes). IMST is strength training for the muscles you use to inhale. Both groups will be performing their version of IMST over a period of 6 weeks. Researchers are hoping that by doing this for 5 minutes a day in the comfort of their own home, people will get health benefits they otherwise might not get.
Researchers will be performing tests to evaluate:
- Vascular function - how healthy the blood vessels are
- Cerebral vascular function - how healthy the blood vessels in the brain are
- Cognitive function
- Physical performance - VO2 max testing assesses this
- Motor function
Results so far are showing that the IMST group, compared to sham subjects, are lowering their blood pressure and improving blood vessel health. Also, the IMST group is performing better on certain cognitive and memory tests. In addition, the IMST group are able to keep their heart rate and oxygen consumption lower during exercise. Consequently, subjects are also showing an increase in exercise tolerance time too.
With all this evidence, researchers hope that by using IMST, people may be able to get their blood pressure under control, decrease their risk of chronic conditions and live healthier lives.
