Study Description
Brief Summary:
The purpose of this randomized, control pilot study is to measure the effects of a gentle, 12 week hatha yoga program on post-menopausal, obese, sedentary South Asian women at risk for cardiovascular disease. Hatha yoga is a form of structured physical exercises known as asanas, combined with breathing exercises called pranayama, and relaxation techniques. The yoga intervention consists of 9 different yoga poses (asanas) and 3 different breathing exercises (pranayama) that can be easily replicated and readily performed by individuals who are middle-aged and older, overweight, unfit, or who suffer from a chronic illness.

Outcome Measures

Primary Outcome Measures :
  1. Change in blood pressure [ Time Frame: baseline, at end of study (12 wks), & 3 months post-study ]
    blood pressure is measured as a specific physiologic index of cardiovascular risk.


Secondary Outcome Measures :
  1. Change in subjective well-being [ Time Frame: baseline, at end of study (12 wks), & 3 months post-study ]
    The Perceived Stress Scale and Abbreviated Duke Social Support Index will be used to measure subjective well-being.

  2. Change in perceived physical well-being [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Pittsburgh Sleep Quality Index, Physical Activity Scale for the Elderly, and Exercise Regularly Scale will be used to measure change in perceived physical well-being

  3. Change in insulin sensitivity [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Fasting insulin & glucose will be measured for change in insulin sensitivity as a related index of cardiovascular risk

  4. Change in inflammation [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    C-reactive protein will be measured for change in inflammation as a related index of cardiovascular risk

  5. Change in serum total cholesterol [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Serum total cholesterol will be measured as a related index of cardiovascular risk

  6. Change in serum high-density lipoprotein (HDL) cholesterol [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Serum high-density lipoprotein (HDL) cholesterol will be measured as a related index of cardiovascular risk

  7. Change in serum low-density lipoprotein (LDL) cholesterol [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Serum low-density lipoprotein (LDL)cholesterol will be measured as a related index of cardiovascular risk

  8. Change in serum triglycerides [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Serum triglycerides will be measured as a related index of cardiovascular risk

  9. Change in waist circumference. [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Waist circumference will be measured for change in visceral adiposity as a related index of cardiovascular risk

  10. Change waist-hip ratio [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Waist-hip ratio will be measured for change in visceral adiposity as a related index of cardiovascular risk

  11. Change in body mass index (BMI) [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Body mass index (BMI) will be measured for change in visceral adiposity as a related index of cardiovascular risk

  12. Change in resting heart rate [ Time Frame: baseline, end of study (12 wks) & 3 months post-study ]
    Resting heart rate will be measured for change in sympathetic activity as a related index of cardiovascular risk

  13. Change in heart rate [ Time Frame: baseline, at end of study (12 wks), & 3 months post-study ]
    Heart rate will be measured for change in sympathetic activity as a related index of cardiovascular risk
