简要总结
We tested the following hypotheses:
- That a standardized yoga therapy will improve insulin sensitivity (primary outcome), and other features of the metabolic syndrome such as hypertension and dyslipidemia (secondary outcomes), we will perform a 2-hour oral glucose tolerance test, fasting blood tests, and a physical examination before and after randomization of subjects to a 10-week yoga therapy intervention or wait-list control group.
- That a yoga therapy is feasible in overweight and underactive individuals with the metabolic syndrome, that adherence to a yoga intervention is acceptable, and that yoga therapy is associated with improved quality of life, we will assess the adherence to twice-weekly yoga group sessions (for weeks1-5) and weekly yoga group sessions (for weeks 6-10), frequency of home yoga therapy practice, and self-reported quality of life before and after the intervention in both treatment groups.
- To elucidate a potential mechanism for the effect of yoga on changes in insulin resistance by evaluating markers of inflammation from adipose tissue (adipocytokines). We hypothesize that these biochemical parameters will show modest improvement with yoga therapy and that changes in these parameters will be associated with improvements in insulin sensitivity.
详细描述
Study Interventions: There will be a 12-week intervention period.
- Yoga Therapy Group: Those randomized to yoga therapy will receive twice-weekly group yoga sessions at the Osher Center for the entire intervention period. The yoga postures and breathing techniques will be taught by a qualified and certified yoga instructor using a standardized protocol that was determined by a Yoga Expert Panel. Each group yoga session will take approximately 90 minutes. Participants will also be required to practice yoga at home at least 3 times per week, and be given yoga materials (mat, blocks, straps), an instruction manual, and a video for their use at home. They will be asked to keep a calendar log of the dates/times that they practiced yoga at home. This group will also receive a 20-30 minute session with a counselor to discuss Standard Health Education at the beginning of the 12-week intervention. This session will be similar to the control group intervention.
- Standard Health Education Group: Participants assigned to the standard health education group will receive an individual 20-30 minute session with a trained research associate within a week of their baseline visit. In this session, participants will be informed of the importance of a healthy lifestyle, given written information of the Food Guide Pyramid12 and told to follow the equivalent of the National Cholesterol Education Program Step I diet13. They will be counseled to reduce weight and increase physical activity. This is similar to the intervention given to the "Standard Lifestyle Group" in the Diabetes Prevention Program4.
