Is BIA bioelectrical impedance accurate for measuring body composition?
The main variable is actually the water content in the body. It is only measured at the daily fixed time, usually in the afternoon, and after non strenuous exercise, after sweating, it is basically accurate.The relative deficiency is that it is usually measured by hands or feet. If the belly fat content is high, it is difficult to get an accurate response, and it needs to be judged by other methods.
Fat non conductive, muscle moisture content, good conductivity, so through the two points between the current and voltage changes, you can measure the resistance, the higher the resistance, the higher the fat content.
It's available.Not the most accurate method, but cheap, convenient, non-invasive, repeated daily, easy for continuous evaluation.
