The rates of obesity and related health conditions are rising at an alarming rate, especially among minority populations. Nutrition and physical activity have been particularly linked to the high rates of heart disease and type 2 diabetes. This study was to determine if pedometers promoted daily walking exercise reflected by changes on selected physiological measurements in older Mexican American females. Significance in the study was determined at the 95% level of confidence. The participants for this study were 55 Mexican American females ages 60 to 75 randomly assigned to a treatment or control group. An analysis of covariance was used to examine the data for significance of difference between group means. The variables weight, systolic blood pressure, diastolic blood pressure, predicted Max VO2 and waist girth were influenced by the treatment. The variables BMI and resting heart rate were not influenced by the treatment
