Acute Fetal Response to Prenatal Yoga

University of Missouri, Kansas City46 enrolled

Overview

Prenatal yoga has become a popular means of exercise during pregnancy.

In 2012, yoga was reported to be practiced by approximately 20 million Americans, out of which 82% are women practitioners. The effects of yoga on the fetus have not been demonstrated. The purpose of this study is to evaluate the acute fetal response to yoga exercises by assessing fetal well-being via ultrasound and non-stress testing among healthy women. The investigators hypothesize that yoga during pregnancy does not have any acute negative effects on fetal behavior as assessed by umbilical artery Dopplers and fetal heart rate or maternal vital signs.

Outcomes

Primary Outcomes

umbilical artery S/D ratio (Dopplers)

The primary outcome of our study will be assessing umbilical artery S/D ratio (Dopplers). Doppler examination will be performed on the day of intervention. Approximately 20-30 minutes prior to the intervention and 20-30 minutes after a 1 hour intervention.

Time frame: An umbilical artery ratio will be obtained on the day of intervention via an ultrasound machine. The first assessment will be before the intervention. The second assessment will be after a 1 hour intervention.

Secondary Outcomes

Fetal Heart Rate

The secondary outcome will be the fetal heart rate. To assess if there is a change from 20-30 minutes prior to an intervention, to 20 -30 minutes after a 1 hour intervention.

Time frame: Fetal heart rate will be obtained on the day of intervention via a non stress test. The first assessment will be before the intervention. The second assessment will be after a 1 hour intervention.
