Take your practice to the next level with professional application of advanced Body Composition Analysis.

  • Sports Programs

    Sports Programs

    Track improvements in segmental muscle development, and utilize Phase Angle to track progress and recovery at a cellular level, helping you determine when it’s safe to allow an injured athlete to resume training and tough workouts.

  • Fluid Management

    Fluid Management

    Precise tracking and management of extracellular and intracellular fluid is of utmost importance in a wide variety of diseases, including but not limited to cardiac and renal deficiency. Utilize the Edema Index to evaluate imbalance, and track body water changes as frequently as needed.

  • Obesity Treatment

    Obesity Treatment

    Prioritize clinically important indicators of metabolic risk by tracking changes in visceral fat area. Help evaluate if patient is at risk, and determine if current treatment regimens are effective.

  • Evaluation of Sarcopenia

    Evaluation of Sarcopenia

    In elderly populations, muscle strength can decline much more rapidly than muscle mass. By evaluating muscle effectiveness through evaluation of cellular health, healthcare professionals now have a more useful indicator that may provide early warning for fall risk.

  • Pediatrics


    Body composition analysis provides additional evaluation parameters beyond height and weight. As childhood obesity becomes a growing problem, regular evaluation of excessive body fat has become a key measurement to track

  • Nutrition


    In addition to traditional evaluation methods of nutrition like BMI, whole-body and segmental measurements of muscle and fat provide additional indicators for nutritionists and dieticians.

Bioelectrical Impedance Analysis

What is Body Composition?

First of all, what is "Body Composition"? Simply put, body composition analyzers analyze your body, dividing it into the core components of body water, fat, protein, and minerals. This provides a detailed and accurate breakdown of weight, giving you key insight that traditional methods such as BMI can't provide.

Why isn't BMI enough for advanced use?

Body Mass Index (BMI) is a common method used to assess an individual's health, by comparing their weight with their health. The primary limitation of BMI is that it only utilizes full body weight, and there's no way to tell if weight changes are due to fat or muscle. Two people with the same BMI will be categorized as having the same health risk, even if one person if mostly fat, and the other is mostly muscle!

Why is Body Composition important?

Traditionally, many fitness or dietary goals have been focused on gaining or losing weight - understandably, if all you have is a weight scales. With Bioelectrical Impedance Analysis (BIA) making body composition accessible, safe, and affordable compared to other analysis methods, you can regularly track the key components of your body, providing a valuable snapshot into your health status!

Introduction to BIA

BIA works by sending a weak alternating current through the body, and measuring the resulting drop in voltage caused by the resistance level of body tissue against the current, known as "Impedance" or "Z".

Impedance is formed using a combination of two components: ohmic resistance (known as "Resistance" or "R") of the electrolyte-containing extra- and intracellular fluid, and the capacitive resistance (known as "Reactance" or "Xc") produced by cell membranes.

What can we learn from Resistance?

In general terms, water acts as a conductor, so more body water correlates with decreased Resistance. According to this principle, because muscle contains a significant amount of water, subjects with increased muscle mass will have less Resistance. Conversely, because fat acts as an insulator, more fat correlates with increased Resistance.

What can we learn from Reactance?

When the electric current passes through body cells, cell membranes can store the charge and act like capacitors, creating capacitive resistance. Thus, Reactance is used to determine the cell's ability to store energy, indirectly reflecting cellular integrity and strength.

Using clinically validated algorithms, BIA devices can calculate the amount of fat, muscle, body water, and other parameters using Impedance, Reactance, Resistance, and other variables such as height, gender, age, and weight.

The applicability of a BIA device fundamentally depends on the applied mathematical equations and algorithms used to calculate body composition. Development and validation of these equations is a technically complex process, and the validity of the equations ultimately determines the accuracy of the BIA device!
