Study to Measure Relaxation From Different Types of Focused Breathing Exercises
This trial has been terminated.
|Conditions||breathing, mind-body practices, yoga, meditation|
|Sponsor||Vanderbilt University Medical Center|
|Start date||August 2014|
|End date||December 2015|
|Trial size||24 participants|
|Trial identifier||NCT02226744, 131700|
Mind-body practices, such as yoga, ta'i chi, mindfulness and biofeedback, commonly use slow breathing techniques to induce physiological and mental relaxation. Medical research suggests that slow breathing techniques induce physiological relaxation. This 6 week study will compare the effects of different types of breathing. The hypothesis is that different breathing techniques produce different physiological and mental changes.
