Question

Quizplus · Accepted Answer

Bioelectrical impedance is the body fat assessment technique that relies on the principle that water and electrolytes conduct electricity. It involves sending a small electrical current through the body and measuring the resistance to the current flow, which can determine body fat percentage. Skinfold measurements involve calipers measuring fat layer thickness at specific points on the body, air displacement involves measuring body volume inside a chamber, and underwater weighing involves measuring weight and calculating body density.
