Body composition determination by bioelectrical impedance analysis (BIA) is based upon the:
a. amount of electrical current that flows through body tissues such as fat and muscle.
b. amount of light absorbed and reflected by body tissues such as fat and muscle.
c. density of the body.
d. volume of the body.
Question 2
Determination of body composition by skinfold measurements is based upon the assumption that:
a. people with more body fat have thicker skin.
b. the amount of fat under the skin in specific locations is closely related to total body fat.
c. skinfold thickness in people with more body fat will be lower because fat is compressed more when pinched.
d. skinfold calipers measure the amount of light absorbed and reflected by body tissues such as fat and muscle.
