Bioelectrical Impedance Analysis (BIA) estimates body composition by measuring resistance to an electrical current, with fat tissue presenting more impedance than lean tissue. Accuracy is influenced by electrode placement, and BIA is an essential tool for estimating body fat percentage.
Bioelectrical Impedance Analysis (BIA) is a method used to estimate body composition by measuring the resistance encountered by a small electrical current passed through the body. Fat tissue, having less water, poses more impedance compared to lean tissue rich in water and electrolytes. The accuracy of BIA devices can vary, with point-to-point electrodes offering better results than portable options.
