The purpose of this study was: to validate metabolic equivalents (METs) · hr/week by comparing with maximal oxygen uptake (VO 2 max) as a measure of physical activities, to examine the relationships between METs · hr/week,VO 2 max, and coronary heart disease (CHD) risk factors according to the goals of METs · hr/week andVO 2 max in ml·kg −1 ·min −1 for health promotion set in the Ex- Key words --metabolic equivalent·hour/week, maximal oxygen uptake, intensity, quantity of physical activity
