| Objective:In this paper, the writer use taijiquan as an intervention on community elderly hypertensive patients, observed moderate taijiquan exercise on the vascular endothelium, lipid metabolism, oxidative stress and other related indicators, analysis of taijiquan on the community elderly hypertensive patients prevention and treatment and related mechanisms, and through the development of the syndrome on exercise prescription, make taijiquan better for the public health service, broaden the research scope of taijiquan on health promotion.Methods:In this study, hypertension patients in community screening of 25 people, of whom the average age was 62.00±3.59 years were graded according to the development of individual exercise intensity.This paper measured each subject’s target heart rate and self-fatigue and impose 1h/day,6 days/week of Small and medium strength such as taijiquan exercise;subjects were detected before the experiment, sports eight weeks,16 weeks height, weight, waist circumference, body fat percentage, blood pressure, pulse and biochemical indicators:vascular endothelial function (ET, NO), lipid metabolism (TG,TC, HDL-C, LDL-C), oxidative stress (MDA, T-SOD,GSH-PX) and related hormones (E, COR,Ang II).Results:(1) After 8 weeks taijiquan exercise, decrease in SBP was very significant (p< 0.01), whereas DBP, pressing of arteries and veins were no significant changes, and after 16 weeks, the subjects SBP, DBP, and pulse pressure difference are significantly decreased (p< 0.01, p< 0.01, p< 0.05), the control group there was no significant change;After 8 weeks and 16 weeks exercise,instantly systolic pressure, diastolic blood pressure were significantly decreased (p< 0.01, p< 0.05), with a significant reduction in the instant heart rate also appears, especially in 8 weeks after the effect is more obvious (p< 0.01). (2) After 8 weeks taijiquan exercise, TC, LDL-C were very significantly decreased (p< 0.01), and BMI, F, TG, HDL-C were no significant changes, and afterl6 weeks, BMI, F, TC, LDL-C were very significant differences (p< 0.01), TG and HDL-C change was not significant, the control group no significant change, individual upward trend; (3) After 8 weeks taijiquan exercise, the rise in serum levels of ET and NO has significant difference (p< 0.01, p< 0.05), after 16 weeks, all have very significant difference (p < 0.01), control group ET and NO were declining trend, but the difference was not significant; (4) After 8 weeks taijiquan exercise, serum E have significantly decreased (p< 0.05), while serum COR, Ang Ⅱ were no significant changes, and after 16 weeks, serum E, COR and Ang Ⅱ were significantly lower (p< 0.01), the control group there was no significant difference; There was a positive correlation and CORE, Ang II (r= 0.933, p< 0.01 and r=0.499, p< 0.05), COR and Ang Ⅱ also positively correlated (r=0.469, p< 0.05); (5) After 8 weeks taijiquan exercise,serum SOD, GSH-PX were significantly increased (p< 0.05), decrease in MDA was very significant (p< 0.01), while after 16 weeks, serum SOD,GSH-PX were significantly higher (p<0.01, p< 0.05), and the decrease in serum MDA was very significant (p< 0.01) and control group in the three indexes have a downward trend, but the difference was not significant; Compared with before exercise, SOD/MDA ratio increases with very significant (p< 0.01); (6) After 16 weeks, SBP and MDA have a positive correlation (r=0.44, p<0.05); DBP and F, LDL-C were positive correlation (r=0.42, p<0.05) (r=0.40, p<0.05), and GSH-PX has a negative correlation (r=-0.43, p<0.05); SOD pulse pressure and there was a negative correlation (r=-0.57, p<0.01).Conclusion:1, Adopt the bull’s-eye rate within the scope of taijiquan exercise prescription is reasonable, basic subjects exercise habit formation, and taijiquan exercise can improve blood pressure, reduce the peripheral resistance, has obvious antihypertensive effect.2,Taijiquan exercise can increase body fat burning with consumption, improve F, BMI and blood levels of TC, LDL-C in the F content and reduced LDL-C concentration can directly cause DBP decreased, may be as one of the antihypertensive mechanism.3, Taijiquan exercise can reduce the content of serum ET participants, increase the content of serum NO, balance, improve endothelial factor may be as one of antihypertensive mechanism, and hormonal regulation, remove free radicals and lipid improve might be collaborative endothelial factor involved in step-down.4, Taijiquan exercise as a form of stress, can reduce sympathetic nervous tension, improve the vagus nerve tension, and significantly reduce serum Ang Ⅱ, E and COR concentration, improve the HPA axis dysfunction within the body. And HPA axis to improve further reduce serum Ang Ⅱ content, make the body in a virtuous circle, this may be as one of antihypertensive mechanism.5, Taijiquan exercise can enhance the subjects cardiopulmonary function, improve the body’s antioxidant capacity, serum gsh-px, SOD activity, MDA content decreased, work together to make the body free radicals, and prompt serum MDA content lower SOD/MDA ratio may be directly involved in the aerobic ability and reach the antihypertensive effects. In addition, Ang Ⅱ content may also be coordinated to reduce the serum GSH-PX level eventually reduce serum MDA content, the specific mechanism needs further research. |
