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.
Your level of physical fitness is how healthy your are. Physical fitness is defined as being in shape, generally healthy and able to do routine exercise. An example of physical fitness is when you are reasonably healthy and you exercise and eat right.
