Physicians use the procedure to: 1  identify abnormalities, such as aneurysms, in the aorta, both in the chest and abdomen, or in other arteries. 2  detect atherosclerotic (plaque) disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke.
Physical fitness is a general state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
The 1996 U.S. Surgeon General's Report on Physical Activity and Health is a landmark document that emphasizes the important link between physical fitness and American health. The components of skill-related fitness include agility, balance, coordination, power, speed and reaction time.
