BIOL 349 Physiology Research Project at WWU

9 Sep


In my Human Physiology course at Western Washington University, we were asked to conduct a research study on a topic of our choice.   My Physiology Lab partners and I studied the impact of Pranayama and Viparita Karani on mean arterial pressure (MAP is a measure of blood pressure) in college-age women.  Above you can see our poster and below a figure from our paper.


Figure 3. Average percent change in mean arterial pressure (MAP) for the treatment and control groups during three time intervals: Posture/Breathing shows the difference between Stages 1 and 2, Recovery is between Stages 2 and 3, and Overall shows the difference between Stages 1 and 3. Error bars show standard error (Tierney et al 2015).

While we did not find a statistically signifiant difference in MAP resulting form the posture; however, we did find that a simple, 5-minute Pranayama practice reduces MAP.  I invite you to have a look at our paper and also take five minutes to practice breathing to the recording I prepared for the study.

Here is a link to the paper.

On a side note, our group’s project won Best Poster in our class.
Great work, ladies!
