Matt is having his body fat assessed by ____, a technique that requires a large device called the BOD POD.

skinfold measurements

dual-energy X-ray absorptiometry

bioelectrical impedance

air displacement

Answer

air displacement

a procedure that is non-invasive test-procedure and there is no technical assistance needed compared to the traditional hydrostatic weighing procedure. Explanation

This is basically a recognized and scientifically validated densitometric method to measure human body composition which requires a large device called the BOD POD. The procedure is completely non-invasive test-procedure and there is no technical assistance needed compared to the traditional hydrostatic weighing procedure. The system simply uses uses whole body densitometry to determine body composition (fat vs. lean). In general terms, the principle by which the machine or this technique operates relies on the physics of Boyle’s Law, which states that pressure and volume vary inversely with one another.
