Abstract:
Obesity and hypertension are among the international problems for which health professionals urge exercise. Exercise might increase if advisers knew how patients normally expend energy. Using the Yale Physical Activity Survey (YPAS), this U.S. study measured energy expenditure in several dimensions of physical activity including exercise, in African American women with hypertension (N = 100). Over half expended at least 6,000 (kilocalories) kcal per week; most expended over 3,500 of those kcal in everyday work activities. Such activities could be enhanced to supplement aerobic exercise. When physical activity is urged to promote health, it is important to consider kcal expenditure beyond exercise.
