About this study

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.

Treatment and study plan

Yoga intervention

Behavioral

Primary outcomes

  1. umbilical artery S/D ratio (Dopplers)

    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.

    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.

Secondary outcomes

  1. Fetal Heart Rate

    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.

    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.
