Physical Fitness Provides Wide Range of Health Benefits
Physical fitness and exercise is the foundation of a healthy lifestyle. Regular exercise is a critical component in maintaining and extending a disease-free life. For example, being fit and physically active significantly reduces the risk of developing potentially fatal illnesses, such as heart disease, stroke, diabetes and cancer. Regular exercise also helps to control weight, reduce high blood pressure (hypertension); contributes to healthy bones, muscles, and joints; reduces falls among older adults; helps to relieve the pain of arthritis; reduces symptoms of anxiety and depression; and is associated with fewer hospital/doctor visits, and medication-usage.
How to Benefit from Exercise
The benefits of physical activity are easily available. People of all ages who are generally inactive can improve their health and well-being by taking regular moderate-intensity exercise, such as 30 minutes of brisk walking, five or more times a week.
Adult Physical Activity Levels
Despite the proven benefits of fitness and physical activity, more than 50 percent of American adults do not get enough physical activity to provide health benefits. 25 percent of adults are not active at all in their leisure time. Activity decreases with age and is less common among women than men and among those with lower income and less education.
Physical Activity Levels of Teenagers
Insufficient physical activity is not limited to adults. More than a third of young people in grades 912 do not regularly engage in vigorous-intensity physical activity. Daily participation in high school physical education classes dropped from 42 percent in 1991 to 32 percent in 2001 (Source: CDC, 2002).
