The study is a randomized 3-month community-based exercise intervention with a control group and 2 different exercise groups: walking group and Chinese square dancing group.Eighteen communities will be selected in Beijing, and they will be age matched and randomly grouped into walking, Chinese square dancing and control groups. Each community will include twenty subjects (ten patients with hypertension and ten patients with hypertension complicated with diabetes) aged 40-69 years. All exercise sessions will be supervised and subject's exercise implementation process will be managed with intelligent equipment. The purpose of the study is to evaluate the effectiveness and safety of different training programs. The demographics data, physical activity questionnaires, blood pressure, blood glucose, blood lipids, height, weight and physical fitness (cardiorespiratory fitness,muscle strength, muscle endurance, flexibility, body composition) will be measured before and after 3-month exercise training .The adverse reactions in the implementation of the interventions will be recorded. The primary outcomes are blood pressure and blood glucose.
The global burden of disease study shows that unreasonable diets and physical inactivity are the largest health risks facing the world today. In recent years, foreign and domestic scholars have gradually introduced the concept of " Exercise is Medicine " guide the the public exercise scientifically. However, under the special cultural background of China, it is urgent to answer how to help the public to realize reasonable scientific exercise, how to choose the popular exercise mode and whether the exercise mode is scientific and effective. Previous meta-analysis studies on the improvement of blood pressure and blood glucose by walking have been published, but few studies on Chinese square dancing have been conducted. Previous studies on whether Chinese square dancing was scientific and effective were mostly small sample population studies carried out by Chinese scholars. The research results were of large heterogeneity, and the research design lacked reasonable consideration. This study intends to select two common exercise mode for scientific evaluation, one is walking and the other is Chinese square dancing. The purpose of this study is to evaluate the efficacy and safety of two common types of exercise (walking and Chinese square dancing) in Chinese patients with hypertension and patients with hypertension complicated with diabetes.

Subjects in this group perform exercise consisting of walking for 30 - 60 min at 40% - 60% HRR intensity 3-5 d•wk-1 for 3 months . Each training includes 5 min warm-up and 5 min cool-down, and the exercise should start after meals for 1 hour . Heart rate is monitored by sports bracelet . Subjects using β-blockers will not use heart rate to monitor exercise intensity , but RPE scores . And RPE( Borg scale) scores are ranged from 11-13.
Chinese square dances have been selected from 24 sets of square dances jointly launched in 2015 and 2017. According to the age and physical health status of the subjects, six dance pieces of are selected as the repertoires of the intervention in this study. Subjects in this group perform exercise consisting of Chinese square dances for 30-60 min at 40% - 60% HRR intensity 3-5 d•wk-1 for 3 months. Each training includes 5 min warm-up and 5 min cool-down , and the exercise should start after meals for 1 hour. Make the subjects step for 30 s to 1 min between each track to adjust the heart rate. Heart rate is monitored by sports bracelet. Subjects using β-blockers will not use heart rate to monitor exercise intensity, but RPE scores. And RPE( Borg scale) scores are ranged from 11-13.
Walking group , Chinese square dancing group and control group are given the same health education brochures or health education lectures once a month . Specific contents of the brochure or lecture include : type 2 diabetes , hypertension related medical knowledge and the significance of intervention treatment ; prevention of type 2 diabetes , hypertension nutrition and exercise recommendations ; basic knowledge of scientific exercise and its matters needing attention .

Time and Frequency of Adverse Reactions and Serious Adverse Events through the study completion
This study will collect the following safety information and record it in the CRF, including: research-related adverse reactions and serious adverse events. The relevant definitions and procedures are as follows. The adverse effects of exercise include: cardiovascular and cerebrovascular diseases, aggravation of complications associated with diabetes/hypertension, and sports injuries. Severe adverse events (SAEs) are defined as conditions that result in any of the following outcomes after exercise intervention: death, life-threatening, hospitalization, permanent or significant disability, dysfunction. If a SAE occurs during the course of the study, the investigator should immediately take appropriate treatment on the subject and terminate the trial. Adverse reactions are asked daily by the researcher. In the event of an adverse reaction, the investigator is required to record the following in the CRF: the time, severity, end time, measures taken, and outcome of the adverse event.
Time frame: Every day during the interventions until the end of the study(3 months)
