8-Point Tactile Electrode System
Utilizing different combinations of four electrodes at a time, InBody520 is
able to break the body into five different segments and measure the composition
of each accurately. By using two electrodes in each limb, it guarantees the same
point of entry and exit every time a subject is tested. The use of fewer
electrodes results in less accuracy and the need for external variables. If
currents are only sent from hand to hand or from foot to foot, the analysis only
covers half of the body, leaving out a major portion of the body in the
assessment. Tetra-polar (8) electrodes are the most effective way to measure
body composition analysis using BIA equipment.
Basal Metabolic Rate
The InBody520 uses lean body mass to determine BMR. Other equations for basal
metabolic rate rely on age, weight, gender, etc. and do not take into account
Lean Body Mass (Muscle Mass). Lean body mass (LBM) is the most important factor
in determining BMR. Muscle burns more calories than fat, so understandably it is
one of the most important components when determining BMR.
