Bioelectrical impedance analysis bia is a commonly used method for estimating body composition in particular body fat and muscle massin bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance resistance of the body. A body fat analyzer measures the resistance the body gives off as this current flows through it.

Body fat resistance measurement. The body fat index is not an indicator of fitness level since the calculation is made with no regard to height or weight. The body fat calculator can be used to estimate your total body fat based on specific measurements. Use the metric units tab if you are more comfortable with the international system of units si. Body circumference measurements and body fat scales that use bioelectrical impedance are both methods you can do on your own. To get the best results measure to the nearest 14 inch 05 cm. Then the sensors in the scale measure the.
Either using a handheld scale or standing on a bia scale a signal passes either from hand to hand or foot to foot. It runs through muscle fat water and bone at different levels and can estimate total body fat. Most body water is stored in muscle. Use a tape measure to determine your waist wrist hip and forearm circumference. You can also find tape. Then input your gender and measurements below to receive a body fat index based on average values.
A basic way to measure body fat percentage is by using a soft tape measure like the kind youd use for sewing to record measurements of different parts of the body. When you step on the scale a small electrical current runs up through your leg and across your pelvis measuring the amount of resistance from body fat. For example the us army uses a body fat calculation that simply requires an individuals age height. The resistance between the conductors will provide a measure of body fat since the resistance to electricity varies between adipose muscular and skeletal tissue. While not as accurate as skinfold measurements taken by a trained. One method allows a weak current to run through the body.
According to the acsm bioelectric impedance analysis bia works by passing a low intensity electric current through the body and measuring its resistance. The faster the current travels from one lead to another the more muscle and less fat the person has. The amount of fat in the body can be measured. Measuring the circumference of certain body parts is a simple method of body fat estimation.
