The Science Behind the Technology

The Evolt 360 uses a scientifically validated test known as Bioelectrical Impedance Analysis (BIA). It is considered the fastest, non-invasive method of screening total body composition.

Bioelectrical Impedance (BIA) works by passing a safe, low intensity electrical current through the body via the tactical points on the machine (feet and hands). In very basic terms, the
resistance to flow of the current determines the difference between muscle mass, fat mass
(including visceral and subcutaneous), water and mineral.

The Evolt 360 advanced measuring system uses a 5 compartment model, which essentially
provides a more accurate measure than a 1 compartment system (ie. Such as a single scale
that claims to use BIA technology.).

BIA was the science that was originally developed for the use in monitoring hospital patients
after surgery, as well as astronauts after space travel. Nowadays, this technology is used in
many areas of medicine, from Nephrology to Oncology, in Sports Science, Fitness, and Medical
wellness, in Nutrition, Weight Management and Lifestyle monitoring.

BIA is considered safe, non-intrusive, reliable and repeatable when conditions are standardized which is why it is often used in scientific research.  Originally BIA was used in medicine as a means to assess loss of lean body mass in immune supressed patients. Bioelectrical impedance analysis (BIA) which is able to properly identify a subject’s health risk of excessively high or low body fatness is being studied and researched by a number of research groups including doctors, clinicians, medical practitioners, and biomedical engineers.

The science behind BIA is well researched and validated in peer-reviewed published literature, the most notable being –

• Bera 2014 Bioelectrical impedance methods for non-invasive health monitoring 
• Carrasco Marginet et al 2017 BIVA for measuring hydration status in young elite synchronized swimmers 
• Castizo Oliver et al 2018 Bioelectrical impedance vector analysis BIVA in sport and exercise A systematic review 
• Ying et al 2011 Accuracy of direct segmental multi-frequency bioimpedance analysis 

The Evolt 360 data analysis methodology that incorporates a 5- point algorithm has been developed based 100% on evidence-based data presented in the research. 

Some of our competitors, use a 3-point algorithm that ignores age and gender (with default male and age settings that override what the individual enters into the system) which have repeatedly been substantiated in the literature as key components to the accurate determination of body composition in all demographics.  

There is no negation of the key point of difference in the Evolt 360 in comparison to other BIA manufacturers, rather, Evolt stands on a platform of substantiated scientific methodology that is consistent with all current evidence-based practice.
