What Is BIA in InBody?⚡️
Bioelectrical Impedance Analysis (BIA) measures what’s inside your body — muscle, fat, and body water — by sending safe, low-level electrical currents through your body’s water.
By analyzing how these currents move through different tissues, InBody reveals a detailed picture of your body composition.
🧠 A Brief History
In the early 1990s, founder and CEO Dr. Kichul Cha recognized that most BIA devices were inaccurate — and from a medical standpoint, often useless for patients who needed body composition analysis the most.
🚀 What Makes InBody Different?
1️⃣ No Empirical Estimations
Results are not based on age, s*x, ethnicity, athleticism, or body shape. InBody measures you, not an average.
2️⃣ Direct Segmental Measurement
Each of the body’s five cylinders — arms, legs, and torso — is measured separately, including the torso where many devices rely on estimations.
3️⃣ Multiple Frequencies
Low and high frequencies analyze intracellular and extracellular water, enabling precise body water analysis.
4️⃣ 8-Point Tactile Electrode System
InBody accounts for contact resistance with strategically placed electrodes to ensure that measurements are accurate and reproducible.
✨ That’s why InBody goes beyond the scale — delivering reliable body composition data for medical, fitness, and clinical applications!
