12周步行锻炼对高血压患者血压及血脂的影响

Effects of 12-week Walking on Blood Pressure and Lipid of Hypertensive Patients

目的:制定个性化的步行运动方式,探讨步行锻炼对血压及血脂代谢的影响,为科学制定高血压运动处方提供依据。方法:经严格筛选,最终有104人完成了整个干预过程。其中,男性27人,女性77人,平均年龄(56.77±5.40)岁,制定个性化的运动方案,采用步行锻炼的运动方式,观察步行锻炼前后血压和血脂变化情况。结果:(1)经12周步行锻炼,受试者收缩压、舒张压、脉压差显著降低(P<0.001)。(2)总体上总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL-c)、TC/LDL-c具有下降趋势,但无显著性意义(P>0.05);高密度脂蛋白(HDL-c)显著性上升(P<0.05)。步行锻炼前血脂异常者,锻炼后LDL-c、TC/HDL-c显著性下降(P<0.05);TC、TG、HDL-c趋向正常的比例增加。结论:(1)制定的运动处方可行。(2)12周步行锻炼后受试者血压下降显著,血脂代谢改善。

Objective： To make up a personal prescription of walking and study the effect of walking on blood pressure and lipid metabolism in order to provide reference for establishing scientifically a hypertensive exercise prescription. Method： 104 essential hypertensive patients（27male and 77 female with the average age of56.8＋5.4）were selected as the subjects. Personal exercise programs were worked out and the exercise method of walking was adopted so as to observe the changes of blood pressure and lipid metabolism before and after the experiment. Result：（1） After 12-week walking exercise, the blood pressure（systolic blood pressure, diastolic blood pressure, and difference of pulse pressure） decreased significantly（P0.001）.（2） TG, TC, LDL-c and TC/LDL-c showed a trend of decrease, but no significant changes（P0.05）. HDL-c rose significantly（P0.05）.For those dyslipidemia patients before the exercise, LDL-c and TC/HDL-c decreased significantly after the experiment（P0.05）. The proportion of the patients, whose TC, TG and HDL-c were heading toward normal,increased. Conclusion： The personal prescriptions of walking are feasible for hypertensive patients. And 12weeks＇ walking can obviously improve blood pressure and lipid metabolism of hypertensive patients.
