Bia measures the electrical conductivity of your body. Most importantly dexa body composition technology provides regional body fat results trunk arms legs pelvis and androidgynoid regions.
Body Fat Analyzer And Scale Yimg
Body fat measurement device how does it work. There are also hand held devices and scales which measure body fat but these are often inaccurate. The handheld machines sometimes used to measure body fat rely on bioelectrical impedance which estimates your body fat using a painless electrical signal thats sent through your body. The device measures your weight and volume to determine your body density then uses these figures to calculate your percentage of body fat. A dexa scan can also measure visceral fat abdominal fat which is often associated with increased risk for cardiovascular disease and type 2 diabetes. Measurements are taken at either 3 or 7 different sites on the body. As you hold the device in both hands an imperceptible electrical current passes through your body.
Similarly a faster speed indicates less resistance and a lower body fat percent. Because it takes different amounts of time for the signal to pass through fat muscle bone and water the time it takes it to move from one side of your body to the other can be used to estimate body fat. A small unnoticeable electrical current is sent from one foot up one leg and down the other leg. Muscle tissue in your body contains a high. The device detects the amount of fat based on the speed at which the signal travels. The caliper method which you can learn to do yourself measures skin folds and then puts those measurements into a formula.
Skinfold calipers measure the thickness of your subcutaneous fat the fat underneath the skin at certain body locations. For our purposes the easiest and most accurate choice is the caliper method. As for accuracy a handheld bia device has about a 35 5 margin of error. Fat is a poor conductor of electricity compared to other components of the body such as muscle. Body fat scales use a technology called bioelectrical impedance analysis to measure body fat. A slower traveling signal usually indicates a higher body fat percent.
