Tai Chi training for patients with coronary heart disease.
ABSTRACT Coronary heart disease (CHD) is the leading cause of death in the developed countries and many developing countries. Exercise training is the cornerstone of cardiac rehabilitation program for patients with CHD, and exercise intensities in the 50-70% heart rate reserve have been shown to improve functional capacity. However, recent studies found exercise with lower intensity also displayed benefits to CHD patients, and increased the acceptance of exercise program, particularly unfit and elderly patients. Tai Chi Chuan (TC) is a traditional conditioning exercise in the Chinese community, and recently it has become more popular in the Western societies. The exercise intensity of TC is low to moderate, depending on the training style, posture and duration. Participants can choose to perform a complete set of TC or selected movements according to their needs. Previous research substantiates that TC enhances aerobic capacity, muscular strength, endothelial function and psychological wellbeing. In addition, TC reduces some cardiovascular risk factors, such as hypertension and dyslipidemia. Recent studies have also proved that TC is safe and effective for patients with myocardial infarction, coronary bypass surgery and heart failure. Therefore, TC may be prescribed as an alternative exercise program for selected patients with cardiovascular diseases. In conclusion, TC has potential benefits for patients with CHD, and is appropriate for implementation in the community.

ABSTRACT: Objective. The purpose of the study was to investigate the effects of a 12-week program of therapeutic Tai Chi on the motor function and physical function of idiopathic Parkinson's disease patients (PDs). Methods. The participants were 22 clinically stable PDs in Hoehn-Yahr stages 1-2 randomly assigned to a therapeutic Tai Chi group (TTC, N = 11) or a control group (CON, N = 9). Two subjects in control group did not complete the study for personal reasons. TTC was performed three days a week (60 min/session). Motor symptoms by the UPDRS were assessed, and tests of physical function were administered before and after the 12-week trial. Results. The TTC group, as compared to the CON group, showed changes in the mentation, behavior, mood, and motor scales of the UPDRS (P < 0.05, P < 0.01, resp.), with no significant main effects on the activities of daily living scale (ADL). However, there was a significant interaction between the time and intervention group on ADL (P < 0.05). There were no significant main effects for any of the physical function variables. There were significant interaction effects in balance and agility (P < 0.05, resp.). Conclusions. This study showed that TTC training had modest positive effects on the functional status of Parkinson's disease patients.10/2013; 2013:548240. DOI:10.1155/2013/548240

ABSTRACT: Abstract Objective was to investigate the effects of Tai Chi exercise on nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) levels, and blood pressure (BP) in patients with essential hypertension (EH). EH patients were assigned to the Tai Chi exercise group (HTC, n = 24), and hypertension group (HP, n = 16) by patients' willingness. Healthy volunteers matched for age and gender were recruited as control (NP, n = 16). HTC group performed Tai Chi (60 min/d, 6 d/week) for 12 weeks. Measurements (blood glucose, cholesterol, NO, CO, H2S and BP) were obtained at week 0, 6, and 12. SBP, MAP, and low-density lipoprotein cholesterol levels decreased, and high-density lipoprotein cholesterol levels increased by week 12 in the HTC group (all p < 0.05 versus baseline). Plasma NO, CO, and H2S levels in the HTC group were increased after 12 weeks (all p < 0.05 versus baseline). SBP, DBP and MAP levels were significantly lower in the HTC than in the HP group (all p < 0.05). However, no changes were observed in the HP and NP groups. Correlations were observed between changes in SBP and changes in NO, CO and H2S (r = -0.45, -0.51 and -0.46, respectively, all p < 0.05), and between changes in MAP and changes in NO, CO and H2S (r = -0.36, -0.45 and -0.42, respectively, all p < 0.05). In conclusion, Tai Chi exercise seems to have beneficial effects on BP and gaseous signaling molecules in EH patients. However, further investigation is required to understand the exact mechanisms underlying these observations, and to confirm these results in a larger cohort.Clinical and Experimental Hypertension 02/2014; 37(1).

ABSTRACT: Purpose: The study aims to evaluate the effects of Tai Chi applied cardiac rehabilitation program(TCCRP) on cardiovascular risks, recurrence risk in ten years, and cardiac specific quality of life in individuals with coronary artery disease. Methods: The sample was comprised of individuals diagnosed with coronary artery disease within six months of the study who were referred by their primary physicians to participate in the TCCRP. The design was a pretest/posttest with non-equivalent groups with 30 in TCCRP program and 33 wait-listed comparison group. Results: The average age of all participants was sixty seven years. At the completion of the TCCRP, the Tai Chi group showed significant reduction in their ten year recurrent risk for coronary artery disease measured by Framingham's algorithm. The quality of life for the experimental group was reported as significantly higher than the comparison group, especially the area of general symptom. Conclusion: The outpatient cardiac rehabilitation with Tai Chi was applied effectively and safely without any complication to individuals with coronary artery disease. Tai Chi can be useful as an alternative exercise for cardiac rehabilitation program which may provide more access to individuals for cardiovascular risk management in the community settings.10/2013; 25(5).
