^aOnly the aerobic component of the 2008 Physical Activity Guidelines for Americans are assessed

^bActivity protocol refers to the type of study in which the cut points were derived: ambulatory (walking/running only) and lifestyle activities (for example, gardening, raking, vacuuming, and playing with children)

^cMethod is the study-specific cut point

^d% Median of the prevalence estimates for meeting the 2008 Physical Activity Guidelines for Americans

^eUnderweight/normal, overweight, and obese classifications are on the basis of body mass index, which is weight (kg) / height (m)². Underweight/normal: < 25.0; overweight: 25.0–29.9; and obese: ≥ 30.0
