Summary—In 1995 the American College of Sports Medicine and the Centers for Disease Control and Prevention published
national guidelines on Physical Activity and Public Health. The Committee on Exercise and Cardiac Rehabilitation of the
American Heart Association endorsed and supported these recommendations. The purpose of the presentreport is to update
and clarify the 1995 recommendations on the types and amounts of physical activity needed by healthy adults to improve and
maintain health. Development of this document was by an expert panel of scientists, including physicians, epidemiologists,
exercise scientists, and public health specialists. This panel reviewed advances in pertinent physiologic, epidemiologic, andclinical scientific data, including primary research articles and reviews published since the original recommendation was
issued in 1995. Issues considered by the panel included new scientific evidence relating physical activity to health, physical
activity recommendations by various organizations in the interim, and communications issues. Key points related to updating
the physical activityrecommendation were outlined and writing groups were formed. A draft manuscript was prepared and
circulated for review to the expert panel as well as to outside experts. Comments were integrated into the final recommendation.
Primary Recommendation—To promote and maintain health, all healthy adults aged 18 to 65 yr need moderate-intensity aerobic
(endurance) physical activity for a minimum of 30 minon five days each week or vigorous-intensity aerobic physical activity for
a minimum of 20 min on three days each week. [I (A)] Combinations of moderate- and vigorous-intensity activity can be performed
to meet this recommendation. [IIa (B)] For example, a person can meet the recommendation by walking briskly for 30 min twice
during the week and then jogging for 20 min on two other days.Moderate-intensity aerobic activity, which is generally equivalent
to a brisk walk and noticeably accelerates the heart rate, can be accumulated toward the 30-min minimum by performing bouts
each lasting 10 or more minutes. [I (B)] Vigorous-intensity activity is exemplified by jogging, and causes rapid breathing and
a substantial increase in heart rate. In addition, every adult should perform...
