Cardiovascular and Immune Responses to Yoga
Conditions
Brief summary
The purpose of this study is to 1) determine whether racial differences are evident in resting arterial stiffness and ambulatory blood pressure between African Americans and Caucasians 2) compare heart rate, blood pressure and cytokine production responses to exercise (yoga) between African Americans and Caucasians; 3) compare isokinetic muscular strength between racial groups; and 4) determine if correlations exist between these measures.
Interventions
One hour of vinyasa yoga will be completed.
