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.
However, exercise scientists have identified nine components that comprise the definition of fitness (Tancred 1995) : 1  Strength-the extent to which muscles can exert force by contracting against resistance (e.g. holding or restraining an object or person).otor Fitness refers to the ability of an athlete to perform successfully at their sport. The components of motor fitness are (Davis 2000) : 1  Agility. 2  Balance. 3  Co-ordination. 4  Power (speed & strength).
