Effect of T'ai Chi Exercise on Hypertension in Young and Middle-Aged In-Service Staff.

Objective: This study aims to investigate the effect of t'ai chi exercise on hypertension in young and middle-aged in-service staff.
Methods: A total of 208 subjects with grade 1 hypertension were enrolled into this study. These subjects were randomly divided into two groups: research group and control group (n = 104, each). On the basis of general daily lifestyle intervention, subjects in the research group underwent 24-Style Simplified t'ai chi exercise for 3 months, whereas subjects in the control group underwent general daily lifestyle intervention. All subjects were followed up at the first and third month of intervention. The body mass index (BMI), blood pressure, blood lipid, and other indexes were measured before and after the intervention, and quality of life was evaluated.
Results: (1) In the research group, after 1 month of exercise, systolic blood pressure (SBP), heart rate (HR), triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) significantly decreased (p < 0.05), while BMI, blood glucose (Glu), diastolic blood pressure (DBP), and pulse pressure (PP) did not significantly change. Furthermore, after 3 months of exercise, BMI, HR, SBP, DBP, PP, TG, TC, LDL-C, and Glu all significantly decreased (p < 0.05). (2) Moreover, the quality of life of subjects in the research group obviously improved after 3 months of t'ai chi exercise (p < 0.05).
Conclusions: t'ai chi exercise can reduce the level of blood pressure in young and middle-aged in-service staff with grade 1 hypertension, control weight, slow down the HR, improve metabolism, and improve quality of life. t'ai chi is an exercise suitable for in-service hypertension subjects.
