COMPARISON OF 2 WALKING INTERVENTIONS ON CHD RISK REDUCTION

本研究的目的是确定体力活动的水平，可以有利于减少墨西哥裔美国妇女充血性心脏病的危险因素。具体目的是确定两种水平的步行对久坐的肥胖女性心血管结果的剂量反应。研究分为两个实验组和一个对照组：一组每周5天，以2.4公里/小时的速度步行2.4公里；第二组每周3天，以每小时4.8公里的速度步行2.4公里。基线，12周，24周人体测量，心率，血压，身高，体重和血脂将被测量。

The purpose of this study is to determine the level of physical activity that can favorably reduce risk factors for congestive heart disease in Mexican American women. The specific aim is to determine the dose response of two levels of walking on cardiovascular outcomes in sedentary, obese women. Two experimental groups and one control group will be studied: one group will walk a distance of 2.4 km at 2.4 km/hr 5 days per week; the second group will walk a distance of 2.4 km 3 days per week at 4.8 km per hour. Baseline, 12 week, 24 week anthropometric measures, heart rate, blood pressure, height, weight and blood lipids will be measured.
