The Effects Of Walking Exercise On Blood Pressure And Blood Glucose And Relative Hormone In Essential Hypertension

Objective:The hypertension is one of the most common cardiovascular diseases impairing human's health in the world. Nowadays, main treat means is use medicine, while non-pharmaceutical is aid method. At present, because of side-effects of the medicine, non-pharmaceutical means is on rising, especially the low intensity aerobic training, which is thought as an efficient method for essential hypertension. The purpose of this experiment was to study the effects of walking exercise on the patients of blood pressure, blood glucose, insulin and angiotensin II in the patients with essential hypertension, aim at exploring the mechanism of aerobic training reducing blood pressure and making up appropriate exercise scheme.Subjects and methods:40 patients ofⅠ,Ⅱgrade and boundary essential hypertension took part in this experiment, including 11 male and 29 female. Age range 48-64 years. Their averages age was 57.68±5.39 years. Patients had not other complicated diseases. All subjects accorded with the 1999 WHO/ISH norm. All patients who volunteered to participate walking activity(with pedometer). During the whole experiment, patients'living habits had n't changed. According to a health examination and questionnaires and step experiment, to make up individual training prescription. The patients practiced a 20-week aerobic training program in walking(60 minutes per time,6 times per week).Before exercise,after 12-week training and after 20-week,blood pressure(BP), heart rate(HR), body mass index (BMI),waist/hip ratio(WHR) and before exercise,after 20-week blood glucose, insulin, angiotensinⅡwere measured and analyzed in all patients.Results and conclusions:(1).The blood pressure decreased obviously in patients with aerobic training in walking. The systolic and diastolic blood pressure and pulse pressure declined about 18.17mmHg and 6.03mmHg and 12.14 mmHg respectively(P <0.01, P<0.001). (2).The body mass index and fat percentage in the subjects changed significantly after 20 weeks'walking exercise declined about 0.95kg/m2 and 2.86% respectively (P< 0.01, P< 0.001). The waist/hip decreased after 12 weeks, while increasing after 20 weeks. (3).The insulin sensitivity of patients was improved after 20 weeks walking exercise. (4).The angiotensinⅡwas increase after 20 weeks walking exercise. Activity of renin-angiotensin system didn't decrease.
