“…Motivala et al (2006) also found that the practice of TC exercise could induce acute decreases of sympathetic nervous system activity as measured by preejection period in healthy older adults. In our previous study, we also found that TC exercise could lead HOMA-IR homeostasis model assessment-insulin resistance, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein cholesterol * N = 25 for the variables LDL-C, HDL-C, LDL-C/HDL-C to increased normalized high-frequency power and decreased normalized low-frequency power 30 min after exercise in patients with coronary artery disease (Chang et al 2008). Animal studies indicated that, independently of alterations in adiposity, sympathetic nervous system physiologically regulates adiponectin production and the resultant serum adiponectin levels (Imai et al 2006).…”

“…In addition, a single bout of TC exercise was found to increase blood glucose, high-and low-affinity insulin receptor numbers, and their binding capacity (Wang 2008). Furthermore, an attenuated parasympathetic nervous activity has been suggested to contribute to the development of insulin resistance (Lindmark et al 2003), and TC exercise has been shown to be associated with an acute effect of increasing parasympathetic nervous activity as shown by an increased in normalized high-frequency power and a decreased in normalized low-frequency power of heart rate variability (Chang et al 2008). However, to our knowledge, the acute effects of TC exercise on adiponectin have not been reported in the literature.…”

The aim of this study was to evaluate the acute effect of a single bout of Tai Chi (TC) exercise on adiponectin and glucose homeostasis in individuals with cardiovascular risk factors. Twenty-six individuals (mean age 60.2 years) with at least one cardiovascular risk factor who had been practicing Yang's style TC exercise for at least 3 months were recruited from a regional hospital in Taiwan. A one-group repeated measured quasi-experimental design was used. Participants completed a 60-min Yang's style TC exercise routine including warm up, stretching exercises, and TC followed by a 30-min resting period. After a 1-week washout period, the same group of participants underwent a control condition in which they were instructed to remain seated for 90 min at the study location. Blood samples were collected both before and after the TC intervention or the sitting condition. The difference between pre-post measurements for adiponectin was 0.58 ± 1.42 μg/ml in the TC trial and -0.46 ± 0.99 μg/ml in the sitting trial. The differences between the two trials were statistically significant (P = 0.004). The changes from pretrial to posttrial were significantly greater for glycerol (P < 0.001), cholesterol (P = 0.046), and LDL-C (P = 0.038) in the TC trial compared with those in the sitting trial. Conversely, the changes were significantly lesser for HOMA-IR (P = 0.004), log (HOMA-IR) (P = 0.001), and glucose (P = 0.003) in TC trial compared with those in the sitting trial. In conclusion, a single bout of TC exercise had a significant positive effect on blood adiponectin concentrations in individuals with cardiovascular risk factors.

“…16,19) A previous intervention study in healthy men 20) also demonstrated that regular aerobic exercise was able to modulate BRS, but not HRV. Recently, Chang 21) demonstrated that 9 months of Tai Chi training in CHD patients enhanced the change in HRV between resting and post-Tai Chi states, without an increase in resting HRV. There are similarities between the study of Chang and the current study that demonstrate more or less the same results, ie, increased reflex autonomic activity without an effect on tonic autonomic activity.…”

SummaryTai Chi is a traditional Chinese conditioning exercise that has been used to integrate slow movements, controlled breathing, and mental concentration. The aim of the study was to determine whether Tai Chi training in addition to cardiac rehabilitation would result in a shift toward increased vagal activity of autonomic markers, such as baroreflex sensitivity (BRS) and heart rate variability (HRV). Twenty patients with coronary heart disease (CHD) (male/female: 13/7, mean age: 67.8 ± 4.2 years, mean interval time after a coronary event: 19.8 months) completed this study. The Tai Chi group (n = 10) practiced supervised Tai Chi training once a week and home-based Tai Chi training three times a week together with conventional cardiac rehabilitation for one-year. The control group (n = 10) conducted the conventional cardiac rehabilitation only. BRS and HRV were evaluated at the baseline and after one-year of Tai Chi training. Compared with the controls, patients in the Tai Chi group showed statistically significant improvement in BRS (P = 0.036). These associations persisted after adjustment for age and other covariates. On the other hand, there were no significant trends seen in HRV. Additional Tai Chi training during cardiac rehabilitation may augment reflex vagal regulation, which adds importantly to knowledge of cardiac rehabilitation on autonomic regulation and clinical management of CHD.

“…In the world, Tai-chi is regarded as a mild-to-moderate intensity aerobic exercise based on Eastern health philosophy [21,22]. Through cultivation of psychological focus, relaxation, bodily coordination, and control, Tai-chi can potentially reduce psychopathological and negative symptoms [23] such as social withdrawal and other mood disturbances, decrease aggression rates [24], and enhance physical and mental quality of life [25,26] and other psychological outcomes [26,27]. Tai-chi originated and is mostly practiced in China [28].…”

Background: Antipsychotic drugs are limited in their ability to improve negative symptoms, quality of life, and medication adherence in patients with schizophrenia. The addition of nonpharmacological interventions like social skills training has a positive effect on medication adherence and decreases rehospitalization rates but is limited in improving patients' symptoms, aggressive behaviors, and quality of life. Aerobic exercise, especially Tai-chi, can potentially reduce psychopathological and negative symptoms, decrease aggressive behaviors, and improve quality of life. It is an ideal rehabilitation intervention for patients with schizophrenia. However, no study has investigated the effects of social skills training plus Tai-chi on outcomes among outpatients with schizophrenia. This study analyzes the effect of antipsychotics combined with community-based integrated interventions on outcomes of schizophrenia. Methods: In this study, a 24-session social skills training plus Tai-chi was used in community settings among patients with schizophrenia. A total of 244 patients were randomly assigned to medication treatment alone (MTA group) or community-based integrated intervention (CBII group), which accepted social skills training plus Tai-chi in addition to medication treatment. Generalized linear mixed models were used to evaluate the intervention effect (group effect), intervention effect over time (time effect), and interaction effect (group × time effect). t tests were used to evaluate between-group differences on clinical variables. Multiple linear regression analysis was used to analyze the differences between the intervention at 12 months and baseline for the Positive and Negative Syndrome Scale (PANSS) negative symptoms and quality of life-social domain. Results: Compared with the MTA group, the CBII group had lower scores on PANSS (F = 17.312, p < 0.001) and negative symptoms (F = 44.909, p < 0.001), a lower risk for aggressive behavior (F = 12.382, p < 0.001), and a greater improvement in adherence to medication (F = 12.391, p < 0.001) after 1 year of intervention. The changes in PANSS total scores, negative scores, and social domain of the World Health Organization Quality of Life Scale-Brief version (WHOQOL-BREF) from baseline to 12 months were significant between the two groups (PANSS total score: t = 4.839, p < 0.001; negative symptoms: t = 8.250, p < 0.001, and quality of life-social domain: t = -2.171, p = 0.031). Multiple linear regression analysis also showed that the intervention was significantly effective for changes from baseline to 12 months on PANSS total score (B = 0.804, p < 0.001), negative score (B = 0.709, p < 0.001), and social domain of quality of life (B = -0.673, p = 0.044). Conclusions: This study suggested that the community-based integrated intervention such as social skills training plus Tai-chi should be part of a rehabilitation effort for patients with schizophrenia in order to improve clinical symptoms, quality of life, and medication adherence.

The Effect of T'ai Chi Exercise on Autonomic Nervous Function of Patients with Coronary Artery Disease

Abstract: The change in heart rate and HRV between resting and post-TC suggested that TC exercise could enhance vagal modulation. The potential beneficial effect of long-term regular TC exercise in patients with CAD merits further investigation.
