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.
缺乏身体活动是心血管疾病（CVD）主要的可改变生活方式风险因素之一。本方案旨在评估太极拳与快走在降低心血管疾病风险因素方面的效果。这是一项有三个组别的随机对照试验，即太极拳组、步行组和对照组。太极拳组将接受太极拳训练，包括每周两次60分钟的课程，为期三个月，以及每天30分钟的自主练习。步行组将每天进行30分钟的快走。对照组将接受常规护理。将从两家门诊诊所招募246名有心血管疾病风险因素的受试者。主要结局指标是血压。次要结局指标包括空腹血脂、血糖和糖化血红蛋白（HbA1c）；体重指数、腰围、体脂百分比；感知压力水平和生活质量。数据收集将在基线、3个月、6个月和9个月时进行。将使用广义估计方程模型来比较各组之间随时间变化的结局。预计太极拳组和步行组都能保持更好的健康状况并改善生活质量，并且太极拳在降低心血管疾病风险因素方面将比快走更有效。
