Siu PM, et al randomly assigned 182 patients with metabolic syndrome an average of 56 years old to 1 year of yoga or a control group. The intervention was found to reduce central obesity and showed a trend towards lower BP. (93)
Wolf, M et al randomly assigned Kundalini yoga to 95 hypertensive patients to be done at home for 15 min twice daily for 12 weeks and compared to a control group. A reduction was seen in both the systolic and diastolic BP for both groups (-3.8/-1.7 mm Hg for yoga and -4.5/-3.0 mm Hg for control groups, respectively). The reduction of BP was not significantly different than control, but it is unclear in the amount of BP medication used and how compliant the patient reporting was. (94)
