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.
Society sets various social standards for what it deems as physically fit, such as washboard abs or bulging biceps. But true physical fitness is much more important: measurements and fitness tests that are statistically linked to calculating disease risks and your odds of having a long, healthy life.
