NCT00328666

Brief Summary

The purpose of this study is to compare the effects of 12 weeks of structured classes of either iyengar yoga (IY) or an enhanced usual care intervention on blood pressure, heart rate variability, quality of life measures, lipid measures, and safety in patients with high-normal to stage I hypertension.
