Question

John underwent a body composition test that involved being submerged to compare his underwater weight with land weight to determine his level of body fat. This method of assessment is known as a ________.

Answer 1

Hydrostatic weighing.

Step-by-step explanation:

Answer 2

Hydrostatic weighing.

Step-by-step explanation:

Hydrostatic weighing may be defined as the method used to find the density or the measurement of the mass per unit volume of the living organisms. This application is based on the Archimedes principle.

The level of the body fat can also be determined by the hydrostatic weighing. The fat content of the individual body can be determined by the formula , Fat % = [4.950 /Density - 4.500]×100. The density needs to be calculated by

Density = Mass in air / Mass in air - Mass in water ÷ density of water - residual volume.

Thus, the answer is hydrostatic weighing.
