Question

1. Wearing loose shorts rather than compression shorts will have what effect on body fat determined by the Bod Pod?

a.) Increases adiabatic air so body fat will be overestimated

b.) Increases adiabatic air so body fat will be underestimated

c.) Increases isothermal air so body fat will be overestimated

d.) Will have little to no effect on measured body fat

e.) Increases isothermal air so body fat will be underestimated

2. Which of the following is an assumption of 2-component models of body composition?

a.) Two of the choices listed

b.) The density of fat is constant among individuals.

c.) Proportions of water, mineral, and protein in the fat-free body are constant among different individuals.

d.) The density of the fat-free body is constant among individuals.

e.) All of the choices listed

3. Which of the following postural deviations would most likely be observed in an individual with osteoporosis?

a.) Scoliosis

b.) Swayback

c.) Kyphosis

d.) Lordosis

Answer 1

Ans 1- Increases isothermal air so body fat will be underestimated.

Air next to the skin and air trapped in hair and the fabric of clothing worn during testing are at isothermal conditions . These isothermal conditions must be taken into account or body fat can be underestimated by as much as 6%.

by Wearing loose shorts air can get trap into them.

Ans 2- e

Most techniques for measuring body composition are based on 2-component models (2-CMs) and depend on assumptions relating to the constancy of the density (DFFM) and hydration fraction (HFFFM) of fat-free mass (FFM).

Ans 3- c

Hunchback (kyphosis) usually refers to an abnormally curved spine. It's most common in older women and often related to osteoporosis.
