Optimizing Chronic Slow Breathing Training To Cause A Therapeutic Effect On Heart Rate Variability, Jennifer Joy Brown

Human Movement Sciences Theses & Dissertations

Heart rate variability (HRV) is a valid and reliable tool that can be used to determine the basic state of an individual's autonomic health. The current study attempted to establish the minimum frequency of breathing practice necessary to produce a therapeutic effect on HRV over the course of a four-week period with four different treatment groups, specifically, groups that practiced a slow breathing protocol for either 2, 3 or 5 times per week, and a control group. Forty-three subjects (14 males, 29 females), ages 18–50 years, were screened, pre-tested, matched for sex, age and HRV, assigned to a specific group …
