Body water, proteins, minerals and body fat which are the components of the human body closely relate to the status of our health. Using the method of quantitative analysis, these elements of body composition and body composition analysis provide basic information required for assessing the status of the body.
First used in the late 1960s, the bioelectrical impedance analysis (BIA) method measures body water by obtaining the impedance index. The impedance index is obtained by applying a small alternating current on the body, based on the principle that the body contains water and that the level of electric resistivity, i.e., resistance, changes according to the amount of water in the body.
The InBody is considered to be approx 98% accurate when compared against DEXA. Q How high is the reproducibility of the InBody? Under the same testing conditions, it shows within an average of +/- 2% of percent body fat.
