title: Physical activity, body composition, and blood pressure: a multimethod approach.
abstract: The purpose of the current investigation was to evaluate, using multiple measures of physical activity, the relationships among physical activity, body composition, resting heart rate, and blood pressure in an adult population. Subjects were 221 male (135 normal weight, 86 overweight) and 221 female (156 normal weight, 65 overweight) subjects participating in a longitudinal study of cardiovascular risk factors in families. All subjects were administered three physical activity questionnaires. Principal components analyses were conducted to reduce measures into empirically derived subscales; this analysis revealed five stable factors in men and four in women. Results indicated that aerobic/leisure time significantly correlated to body composition and resting heart rate in both men and women. Additionally, aerobic/leisure time activity was related to blood pressure in women, and moderate activity was related positively to blood pressure in men. No other form of activity (e.g., light activity, anaerobic activity) was related to either adiposity or blood pressure. The implications of these results are discussed, and future research directions are highlighted.
