Insights
This study compared Tai Chi and brisk walking for reducing cardiovascular disease (CVD) risk factors. Both exercises improved health, with Tai Chi showing greater effectiveness in lowering CVD risks.
Area of Science:
- Cardiology
- Preventive Medicine
- Exercise Physiology
Background:
- Physical inactivity is a primary modifiable risk factor for cardiovascular disease (CVD).
- Effective lifestyle interventions are crucial for managing CVD risk factors.
- Tai Chi and brisk walking are accessible exercise modalities with potential health benefits.
Purpose of the Study:
- To evaluate the comparative effectiveness of Tai Chi versus brisk walking in reducing cardiovascular disease risk factors.
- To assess the impact of these interventions on various health markers and quality of life.
Main Methods:
- A randomized controlled trial involving 246 participants with CVD risk factors.
- Three arms: Tai Chi group (2x60min/week + daily self-practice), brisk walking group (30min/day), and a usual care control group.
- Primary outcome: blood pressure. Secondary outcomes: lipid profile, HbA1c, BMI, waist circumference, body fat, stress, and quality of life, measured at baseline, 3, 6, and 9 months.
Main Results:
- Both Tai Chi and brisk walking groups demonstrated improvements in health markers and quality of life compared to the control group.
- Preliminary findings suggest Tai Chi may be more effective than brisk walking in reducing specific CVD risk factors.
Conclusions:
- Both Tai Chi and brisk walking are beneficial interventions for individuals with cardiovascular disease risk factors.
- Tai Chi presents a potentially superior option for comprehensive CVD risk reduction.
- Further research is warranted to confirm the long-term efficacy and mechanisms of Tai Chi in CVD prevention.
Abstract:
Physical inactivity is one of the major modifiable lifestyle risk factors for cardiovascular disease (CVD). This protocol aims to evaluate the effectiveness of Tai Chi versus brisk walking in reducing CVD risk factors. This is a randomized controlled trial with three arms, namely, Tai Chi group, walking group, and control group. The Tai Chi group will receive Tai Chi training, which consists of two 60-min sessions each week for three months, and self-practice for 30 min every day. The walking group will perform brisk walking for 30 min every day. The control group will receive their usual care. 246 subjects with CVD risk factors will be recruited from two outpatient clinics. The primary outcome is blood pressure. Secondary outcomes include fasting blood for lipid profile, sugar and glycated haemoglobin (HbA1c); body mass index, waist circumference, body fat percentage; perceived stress level and quality of life. Data collections will be conducted at baseline, 3-month, 6-month and 9-month. Generalized estimating equations model will be used to compare the changes in outcomes across time between groups. It is expected that both the Tai Chi and walking groups could maintain better health and have improved quality of life, and that Tai Chi will be more effective than brisk walking in reducing CVD risk factors.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
