太极拳锻炼对在职警察血脂和血管壁弹性的影响效果

Effects of Tai Chi Exercise on Cardiovascular Function of Serving Police

研究目的:探究太极拳锻炼对警察血脂和血管壁弹性的影响效果。研究方法:在哈尔滨市区内招募在职警察105名,随机分为太极组、快走组和对照组,分别于实验前、实验24周后,分别采用Gp O-p Ap法、化学发光法、酶法和浊度法测定血清甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白(HDL)和低密度脂蛋白(LDL);采用科林全自动动脉硬化测定仪,进行踝肱指数(ABI)与肱踝脉搏波传导速度(bapWV)的测量。研究结果:实验24周后,太极组TC含量显著低于对照组(P<0.05),总胆固醇与高密度脂蛋白比值(TC/HDL)显著低于对照组和快走组(P<0.05);快走组TC/HDL显著低于对照组(P<0.05)。太极组两侧bapWV非常显著低于对照组(P<0.01),快走组显著低于对照组(P<0.05)。研究结论:太极拳锻炼在降低在职警察的总胆固醇含量、总胆固醇与高密度脂蛋白比值,以及肱踝动脉的脉搏波传导速度方面优于快走运动,能够有效降低动脉粥样硬化、冠心病等心血管疾病的发生几率。

objective: We explored the effect of Tai Chi exercise on cardiovascular function of police.Methods: 105 in Harbin city recruit on-the-job police,were randomly divided into the tai chi group, fast walking group and the control group.Before experiment,experiment after 24 weeks,we measured serum triglyceride(TG)by the GpO-p Ap method,serum cholesterol(TC)by chemiluminescence method,high-density lipoprotein(HDL)by enzymatic method,and low density lipoprotein(LDL)by turbidity method.And we measured the brachial index(ABI)and brachial pulse wave conduction velocity(bapWV)with the automatic arteriosclerosis meter of omron Japan.Results: After 24 weeks of the experiment,TC content in serum of Tai Chi group was significantly lower than that of the control group(P<0.05),TC/HDL was significantly lower than that of the control group and fast walking group(P<0.05).TC/HDL in the fast walking group was significantly lower than that in the control group(P<0.05).BapWV on the right and left of the Tai Chi group was significantly lower than that of the control group(P<0.01),and bapWV on the fast walk group was significantly lower than that of the control group(P<0.05).Conclusions: Tai Chi exercise reduced the serum total cholesterol,total cholesterol and the ratio of high density lipoprotein cholesterol(hdl-c),and humerus ankle arterial pulse wave conduction velocity.And Tai Chi on the lipid metabolism was superior to the walking motion.In other words,Tai Chi exercise could improve the function of the lipid metabolism and vascular wall elasticity of the serving police,thereby reducing the cardiovascular diseases risk factor such as atherosclerosis,coronary heart disease.
