Bioelectrical Impedance devices use the information from this signal to work out body fat percentage. Tanita offer a range statistical of body fat monitors / scales for use at home - click here for details. Skinfold Measurements This method involves a skinfold caliper to pinch predetermined sites on the body. The tongs pinch the skin, statistical pulling the fat away from the muscles and bones. A gauge on the calipers measures the thickness of that pinch. It is recommended that this statistical test is carried out by a professional and should be repeated to verify measurements. To make the test reliable you should not exercise beforehand. Exercise makes your blood travel to your skin to help you cool down and this causes the skin to swell, making your test inaccurate. Hydrostatic Weighing Tanks This method is the most accurate but also the most uncomfortable. You sit on a scale in a large tank of water and blow all the air out of your lungs, then submerge yourself in the water completely.
