Outcome Measures

Primary Outcomes (2)

  • Change in peripheral blood mononuclear cell reactive oxygen species

    Blood draws will be performed at baseline and at weeks 4, 8, and 12 during the study after randomization and analyzed for free radicals after white blood cells are separated from whole blood.

    Baseline and week 4, 8, and 12 measurements

  • Change in peripheral blood mononuclear cell NADPH oxidase cell NADPH oxidase enzyme activity

    A portion of the white blood cells isolated from a whole blood sample will be frozen and later analyzed for enzyme activity. This will be completed for blood samples obtained at baseline and weeks 4, 8, and 12.

    Baseline and week 4, 8, and 12 measurements

Secondary Outcomes (3)

  • Change in 24-hour blood pressure

    Baseline and week 4, 8, and 12 measurements

  • Change in flow-mediated dilation

    Baseline and week 4, 8, and 12 measurements

  • Change in microvascular endothelial function/thermal hyperemia

    Baseline and week 4, 8, and 12 measurements

Study Arms (2)

Yoga postures or slow, deep breathing

Eligibility Criteria

Age30 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may not qualify if:

  • pregnancy (tests will be administered to all premenopausal females at initial screening and follow up visits);
  • having taken blood pressure or statin medications within the past 3 months (statins have been demonstrated to reduce oxidative stress);
  • infection (viral or other) within the past 4 weeks;
  • having adrenal or endocrine tumors (these could impact blood pressure);
  • renal disease defined as an estimate glomerular filtration rate (eGFR) of less than 60 (creatinine will be tested at initial screening and eGFR will be calculated);
  • hyperaldosteronism;
  • prior myocardial infarction;
  • known coronary heart disease;
  • personal history of stroke;
  • heart failure;
  • cardiac arrhythmias;
  • chronic obstructive pulmonary disease, asthma, or other airflow obstructions;
  • recent chest pain or dyspnea;
  • orthopedic limitations that preclude the execution of yoga postures;
  • current insulin dependence;
  • +6 more criteria
