Determining body fat percentage accurately is crucial for health and fitness goals. Body fat machines like bioelectrical impedance analysis (BIA) and air displacement plethysmography (ADP) offer convenient and efficient solutions.
BIA, a common method, uses electrical impulses to measure resistance through body tissues. Fat has a higher resistance than muscle and water, so the machine calculates body fat based on the resistance encountered. ADP, another reliable technique, measures body volume and density in a sealed chamber. Since fat has a lower density than muscle, the machine estimates body fat based on these measurements.
