Thus, improvements in physical activity can be gained in all segments of society. Fifteen percent of Americans report vigorous activity (activity intense enough to make the heart beat fast and hard breathing for at least 20 minutes or more 3 times a week). Only about 22 percent of Americans report regular sustained physical activity (activity of any intensity lasting 30 minutes or more 5 times a week). What segments of the population are physically inactive? It was estimated that in 1989 physical inactivity cost the nation $5.7 billion due to hospitalizations and other related health care costs. It is felt through the loss of income and productivity when disabling diseases result. Physical inactivity has a major economic impact. Approximately 60% of all Americans age 18 and older report that they are physically inactive. The significance of this relationship lies in the fact that coronary heart disease is the leading cause of death in the United States with over 700,000 deaths annually. It is estimated that approximately 35% of coronary heart disease mortality is due to physical inactivity. How large is the problem of physical inactivity in the United States?
Regular physical activity has been shown to help protect against first cardiac episode, help patients' recovery from coronary surgeries, and will reduce the risk of recurrent cardiac events. Twice as many adults in the United States are physically inactive than smoke cigarettes.
One reason it has such a large affect on mortality is because of its prevalence. It ranks similarly to cigarette smoking, high blood pressure, and elevated cholesterol. Physical inactivity is a significant risk factor for CVD itself. Less active, less fit persons have a 30-50 percent greater risk of developing high blood pressure. It also helps prevent the development of diabetes, helps maintain weight loss, and reduces hypertension, which are all independent risk factors for CVD. Regular physical activity reduces the risk of dying prematurely from CVD. What are the consequences of physical inactivity for cardiovascular disease (CVD)? 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. Moderate activities include pleasure walking, climbing stairs, gardening, yard work, moderate-to-heavy housework, dancing and home exercise.
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. This recommendation is consistent with guidelines established by the Centers for Disease Control and Prevention, and American College of Sports Medicine. 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. The American Heart Association recommends 30-60 minutes of aerobic exercise three to four times peer week to promote cardiovascular fitness. Physical inactivity is a term used to identify people who do not get the recommended level of regular physical activity.
