Bioelectrical Impedance Analysis (BIA) Terminology
Body Fat - Total Mass of adipose tissue as we know can affect overall health. Excessive accumulation, particularly visceral fat (around internal organs), is associated with metabolic disorders such as:
Lean Body Mass – Is the non-fat tissue of the body and includes:
Dry Lean Weight: Is Lean Body Mass minus Total body water and includes Bone and lean tissue.
Lean tissue is crucial for overall health and functionality. It plays a significant role in:
Maintaining or increasing lean tissue mass is often a focus in fitness and health programs, as it can improve metabolic rate, physical performance, and reduce the risk of various diseases.
Total Body Water (TBW) – The volume of water in the body. Includes Intra & Extracellular water.
Extracellular Water (ECW) – Is the fluid found in the extracellular compartment. It includes plasma, lymph and intestinal fluid.
Intracellular Water (ICW) – Is the fluid found inside the cells of lean tissue. Higher Intracellular fluid levels are found in people with higher muscle mass.
Body Cell Mass (BCM) – Represents the metabolically active component of the lean body mass. In other words, the protein rich compartment involved in energy expenditure. BCM consists of:
Phase Angle (PA) - The phase angle is a non-invasive measurement and provides valuable insights into body composition and health that are not captured by simple measurements of weight or body mass index (BMI).
Higher phase angle values reflect a larger cellular mass, better cell membrane integrity and better cell function. An average PA in normal health people is between 5 and 8.
