COMPARISON OF 2 WALKING INTERVENTIONS ON CHD RISK REDUCTION

这项研究的目的是确定可以有利地降低墨西哥裔美国女性充血性心脏病风险因素的体力活动水平。具体目的是确定两种水平的步行对久坐不动的肥胖女性心血管结果的剂量反应。两个实验组和一个对照组将被研究：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4.8公里/小时的速度步行2.4公里。基线、12周、24周进行人体测量，测量心率、血压、身高、体重和血脂。

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.
