Tai Chi Exercise is More Effective Than Brisk Walking in Reducing Cardiovascular Disease Risk Factors
Invited conference paper presented and published in conference proceedings


摘要Background: Physical inactivity is one of the major modifiable lifestyle risk factors associated with cardiovascular disease (CVD). Tai Chi (TC) is safe and popular among older adults; yet direct comparisons between TC and brisk walking (BW) on reducing CVD risk factors are lacking.
Methods: A total of 246 adults (mean age=64.4±9.8 years, 45.5% men) with hypertension and two other CVD risk factors (i.e., smoker, diabetic, dyslipidemia, or overweight) were randomly assigned to either TC (n=82), BW (n=82), or control (C, n=82) groups. The TC and BW groups had 150 minutes/week, moderate-intensity physical activity for three months; with home-based practice encouraged for another six months. The primary outcome was blood pressure (BP). Secondary outcomes were: fasting blood sugar (FBS), HbA1c, total cholesterol, triglycerides, high and low density lipoprotein, body mass index (BMI), waist circumference and perceived stress. Data were collected at baseline, post-intervention at 3-month, 6-month and 9-month follow-up assessments. Generalized estimating equations models compared changes in the outcomes over time between groups.
Results: At baseline, average BP=141/81, smokers=11%, diabetics=58%, dyslipidemia=61%, average BMI=26; with no significant differences between groups. TC significantly lowered BP (systolic -13.33 mmHg; diastolic -6.45 mmHg), FBS (-0.72 mmol/L), HbA1c (-0.39%), and perceived stress (-3.22 score) at 9-months, compared to C group. Pairwise comparisons indicated significantly greater reductions in SBP (p<0.001), DBP (p=0.049), FBS (p=0.001), HbA1c (p=0.002), and perceived stress (p=0.027) in TC group, compared to BW group. No significant changes in other CVD risk indicators over time between groups were observed.
Conclusion: TC was better than BW in reducing several CVD risk factors, and can be recommended as a viable exercise to build a healthier life free of CVD.
