Abstract
INTRODUCTION The antioxidant and anti-inflammatory effects of Tai chi (TC) exercise training in healthy older adults has been demonstrated. However, there are no studies on this effect in older adults with metabolic syndrome (MetS). PURPOSE The aim of this study was to determine the effect of TC exercise on oxidative stress and inflammatory markers in older adults with MetS. METHODS A quasi-experimental study was carried out with a sample of 110 older sedentary volunteers with clinical diagnoses of MetS: (i) a control group, n = 50, of individuals who do not participate in physical exercise, of which 37 fulfilled the entire study protocol, and (ii) an experimental group, n = 60, of subjects enrolled in a TC exercise training program (eight-form easy), 5 days a week for 6 months, in sessions of 50 min, under the supervision of a qualified instructor, of which 48 fulfilled the entire study protocol. We measured in both groups (pre- and post-intervention) the following cardiovascular parameters: resting heart rate (RHR), diastolic and systolic blood pressure (DBP and SBP), mean arterial pressure (MAP), RHR-SBP product, RHR-MAP product; glycosylated hemoglobin (HbA1c); oxidative stress markers (superoxide dismutase, total antioxidant status, thiobarbituric acid reacting substances, and oxidative stress score); and inflammation markers (TNF-α, IL-6, IL-8, and IL-10). RESULTS A statistically significant decrease in HbA1c concentration was observed in the TC group compared with the control group (p < 0.05). This group also showed a statistically significant increase in TAS and a decrease in the oxidative stress score (p < 0.05). We did not observe changes in the cardiovascular parameters (RHR, DBP, SBP, MAP, RHR-SBP product, and RHR-MAP product) in the TC experimental group compared to the control group. CONCLUSION Our findings suggest that the practice of TC exercise has an antioxidative and hypoglycemic effect in the elderly with MetS.

Abstract
Obesity, metabolic syndrome, dyslipidemia, and poor quality of life are common conditions associated with hypertension, and incidence of hypertension is age dependent. However, an effective program to prevent hypertension and to improve biomedical factors and quality of life has not been adequately examined or evaluated in Chinese older adults. This study aims to examine the effectiveness of a Tai Chi program to improve health status in participants with hypertension and its related risk factors such as dyslipidemia, hyperglycemia, and quality of life in older adults in China. A randomized study design was used. At the conclusion of the intervention, 266 patients remained in the study. Blood pressure and biomedical factors were measured according to the World Diabetes Association standard 2002. A standardized quality-of-life measure was used to measure health-related quality of life. It was found that a Tai Chi program to improve hypertension in older adults is effective in reducing blood pressure and body mass index, maintaining normal renal function, and improving physical health of health-related quality of life. It did not improve existing metabolic syndrome levels, lipid level (dyslipidemia) or fasting glucose level (hyperglycemia), to prevent further deterioration of the biomedical risk factors. In conclusion, Tai Chi is effective in managing a number of risk factors associated with hypertension in Chinese older adults. Future research should examine a combination of Tai Chi and nutritional intervention to further reduce the level of biomedical risks.

Abstract
BACKGROUND The aim of this study was to explore the potential benefits of the Dejian mind-body intervention (DMBI) for psychological and physical health in older Chinese adults. METHODS After confirmation of eligibility, the subjects were invited to receive DMBI once a week for 12 weeks. The intervention involved components of learning self-awareness and self-control, practicing mind-body exercises, and adopting a special vegetarian diet. Intervention-related changes were measured using the Perceived Stress Scale, Geriatric Depression Scale, Pittsburgh Sleep Quality Index, Chinese Constipation Questionnaire, and self-report ratings of health. Indicators of metabolic syndrome and walking speed were also measured. RESULTS Of the 44 subjects recruited, 42 (54.8% men) completed the study, giving an adherence rate of 95%. There was a significant reduction in perceived stress (P<0.05). A significant improvement was also found in systolic blood pressure among those who had abnormally high blood pressure at baseline (P<0.05). Physical fitness as reflected by walking speed was also significantly increased after the intervention (P<0.05). Sleep disturbances were reduced (P<0.01). Self-rated health was significantly enhanced, with the percentage rating very good health increasing from 14.3% at baseline to 42.8% after the intervention (P<0.001). No intervention effect was found for waist circumference, lipids and fasting blood glucose levels, Pittsburgh Sleep Quality Index global score, and constipation measures. CONCLUSION The DMBI was feasible and acceptable, and subjects showed some improvements in psychological and physical health. A larger controlled trial is needed to confirm these promising preliminary results.
