  Purpose

The proposed study will compare a well defined and integrated yoga practice (postures/breath control/meditation) to a conventional exercise program in reducing hypertension. The expected outcomes include data on the effects of yoga on ambulatory blood pressure, psychosocial stress, and the autonomic system in individuals with pre- and Stage I hypertension. The information gained in this study will have a positive impact by providing critical preliminary and feasibility data to support a larger multi-ethnic randomized clinical trial on the effects of yoga on individuals with hypertension.

Arms Assigned Interventions
Experimental: Yoga
The integrated yoga program was designed to: 1) include the three primary elements of yoga as most commonly practiced in western cultures (physical postures, breath control and meditation); and 2) be appropriate for those without any prior yoga experience and with pre- and Stage I hypertension. The yoga program was designed by Eddie Stern, Founder and Director of "Ashtanga Yoga New York" (AYNY) in consultation with Drs. Hagins and Rundle, and are in large part congruent with the yoga program we studied previously (see Preliminary Studies). The yoga class includes: instruction on yogic principles regarding moral precepts (yamas and niyamas); active postures requiring mild-moderate physical exertion; conscious control of the breath in synchrony with active postures; and meditation. We expect approximately 10-15 minutes of the integrated yoga program to consist of isolated practice of meditation (occurring independently of the moving postures, typically in seated or lying positions).
Other: Yogic practice
breathing, meditation, physical postures
Active Comparator: Conventional Exercise
Conventional exercise such as standing toe touch with arm swings, curl ups, push ups, leg lifts, etc. All done at a relatively slow rate which will be non-aerobic and at an average rate across the session of 3 METs
Other: Conventional Exercise
Standard physical exercises such as toe touch in standing, curl ups, push ups, leg lifts
