Physical inactivity is a term used to identify people who do not get the recommended level of regular physical activity. The American Heart Association recommends 30-60 minutes of aerobic exercise three to four times peer week to promote cardiovascular fitness. In 1996 the Report of the Surgeon General on Physical Activity and Health recommended the minimum level of physical activity required to achieve health benefits was a daily expenditure of 150 kilocalories in moderate or vigorous activities. This recommendation is consistent with guidelines established by the Centers for Disease Control and Prevention, and American College of Sports Medicine. It also is consistent with the 1996 consensus statement from the National Institutes of Health, recommending adults to accumulate at least 30 minutes of moderate activity most days of the week. Moderate activities include pleasure walking, climbing stairs, gardening, yard work, moderate-to-heavy housework, dancing and home exercise. More vigorous aerobic activities, such as brisk walking running, swimming, bicycling, roller skating and jumping rope — done three or four times a week for 30-60 minutes — are best for improving the fitness of the heart and lungs.
