Question

1.) Air that is not exhaled underwater increases buoyancy of the body and will result in an overestimation of body fat.

True or False

2.) When performing hydrostatic weighing, an accurate underwater weight can typically be determined from 1-2 trials, with little accuracy gained by measuring underwater weight more than two times.

True or False

3.) When calculating body density, the value should be rounded to two places to the right of the decimal (e.g., 1.05).

True or False

4.) BIA methods are often preferable to skinfolds measurements for determining the body composition of athletes.  

True or False

Answer 1

1) False

   The air that is not exhaled underwater increases the buoyancy of the body but it will not result in an overestimation of the body fat.

2) False

     It cannot be determined accurate value of the weight when a person is performed hydrostatic weighing, because the value changes according to a small variation in the setup.

3) True

   During calculating the body intensity, the value should be rounded to two places to the right of the decimal.

4) True

   During the bioelectrical impedance analysis the measurements could be taken for analysis of skin fild measurements for body composition of athletes.
