| Epidemiological investigations show that prehypertension has a higher incidence,and cardiovascular risks and target organ damage may occur in the prehypertension.Intervention from the prehypertension stage can delay the development of hypertension in patients with prehypertension.The current interventions for prehypertension are mainly lifestyle interventions,especially sports interventions.Aerobic exercise,as the antihypertensive exercise recommended by the current guidelines,has a clear antihypertensive effect,but the compliance of aerobic exercise people is low,while Tai Chi exercise is simple and easy to practice,safe,and easier to be accepted by the crowd.As one of the traditional Chinese health exercises,Tai Chi is closely related to the basic theories of traditional Chinese medicine.During its practice,it emphasizes the combination of movement,consciousness,and breathing,and emphasizes the unity of body and mind,so that the body can achieve a state of balance between yin and yang.The development concept of "Heart Medicine" is the same.Objective:By observing the dynamic changes of blood pressure and related indicators of variability of the patients with prehypertension,which are caused by doing Tai Chi and the aerobic exercise during 24hours,this paper aims to assess the influence of Tai Chi and aerobic exercise on blood pressure and blood pressure variability of patients with prehypertension.It further evaluates whether the effectiveness of Tai Chi is superior to aerobic exercise,so as to provide a new idea for the patients with prehypertension of how to choose the way of sports to improve their health condition.Methods:Sixty-one patients with prehypertension were randomly divided into Tai Chi group(n=30)and aerobic exercise group(n=31).Patients in both groups were given guidance of lifestyle intervention,Tai Chi group combined with Tai Chi exercise intervention for 12 months,and aerobic exercise group combined with aerobic exercise intervention for 12 months.Observe the changes of blood pressure index,blood pressure variability index,heart rate index,fasting blood glucose,blood lipid,and body mass index before and after the intervention in the two groups to evaluate the curative effect.Among them,blood pressure parameters include 24-hour average systolic blood pressure,daytime average systolic blood pressure,night average systolic blood pressure,24-hour average diastolic blood pressure,daytime average diastolic blood pressure,night average diastolic blood pressure;blood pressure variability parameters include 24-hour systolic blood pressure standard deviation,24 hourly standard deviation of diastolic blood pressure,standard deviation of daytime systolic blood pressure,standard deviation of daytime diastolic blood pressure,standard deviation of night systolic blood pressure,standard deviation of night diastolic blood pressure;blood lipids include total cholesterol,triglycerides,high-density lipoprotein,and low-density lipoprotein.Results:1.Blood pressure indicators with Ambulatory blood pressure monitoring:There was no significant difference in blood pressure indicators before intervention between the two groups of patients(P>0.05),and they were comparable.The blood pressure indexes of the Tai Chi group and the aerobic exercise group after the intervention were significantly lower than before the intervention,and the differences were statistically significant(P<0.05);the 24-hour average systolic blood pressure and the daytime average systolic blood pressure of the Tai Chi group The degree of reduction in the aerobic exercise group was significantly better(P<0.05).2.Blood pressure variability indexes with Ambulatory blood pressure monitoring:The comparison of the blood pressure variability index of the two groups of patients before intervention,the difference was not statistically significant(P>0.05),and it was comparable.The 24-hour standard deviation of systolic blood pressure,the 24-hour standard deviation of diastolic blood pressure,and the standard deviation of day diastolic blood pressure measured by ABPM after the intervention in the Tai Chi group were significantly lower than those before the intervention,and the difference was statistically significant(P<0.05)),the standard deviation of systolic blood pressure,standard deviation of night systolic blood pressure,and standard deviation of night diastolic blood pressure after intervention in Tai Chi group were not significantly different from those before intervention(P>0.05);blood pressure measured by ABPM after intervention in aerobic exercise group There was no significant difference in the variability index compared with that before the intervention(P>0.05).3.Average heart rate indicators with ABPM:The comparison of the heart rate indicators of the two groups of patients before intervention,the difference was not statistically significant(P>0.05),and it was comparable.The 24-hour average heart rate,daytime average heart rate,and night average heart rate of the Tai Chi group after intervention were significantly lower than those before intervention,and the difference was statistically significant after testing(P<0.05);The 24-hour average heart rate,daytime average heart rate of the aerobic exercise group after intervention were significantly lower than those before intervention,and the difference was statistically significant after testing(P<0.05);the Tai Chi group's 24-hour average heart rate and daytime average heart rate decreased significantly better than the aerobic exercise group(P<0.05).4.Physical and chemical indicators:There was no significant difference in fasting glucose,blood lipids,and body mass index between the two groups of patients before intervention(P>0.05);there was no significant difference between the two groups of patients in fasting glucose and blood lipids after intervention and before intervention(P>0.05);The body mass index of the two groups of patients after the intervention was significantly lower than that before the intervention,and the difference was statistically significant after testing(P<0.05);the decline in the Tai Chi group was not statistically compared with the aerobic exercise group academic significance(P>0.05).Conclusion:1.Both Tai Chi and aerobic exercise can reduce the blood pressure of patients with prehypertension,and the effect of Tai Chi group is better than that of the aerobic exercise group.2.Tai Chi can effectively reduce the variability of systolic and diastolic blood pressure in patients with prehypertension,aerobic exercise has no positive significance in reducing blood pressure variability in patients with prehypertension.and the effect of Tai Chi group in improving the variability of blood pressure is stronger than that of the aerobic exercise group.3.Tai Chi and aerobic exercise can reduce the heart rate of patients with prehypertension,and Tai Chi exercise can reduce the heart rate of patients with prehypertension more effectively.4.Both Tai Chi and aerobic exercise can effectively reduce the BMI level of patients with prehypertension,and there is no significant difference between them. |
