All forms of BIA have been established as being identical in terms of the method of operation and the utilization of impedance measures that incorporate an alternate electrical frequency to determine body composition, despite marketing collateral of competitors that suggests otherwise. Similarly, whilst our competitors provide research papers in which their devices have been used as part of the methodology of data collection, those studies do not constitute peer-reviewed substantiation of the validity or reliability of those devices. Rather, there is an implied reliability that our competitors refer to as demonstrating the features of their devices, which is very clever marketing, but devoid of substantiated scientific support.
BIA and an alternating current passed through the body is identical regardless of the manufacturer however the algorithms used by different companies is where the variability exists. 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. So the aggressive marketing of some competitors, in fact, highlights a major flaw in their system that categorically demonstrates a high degree of questionably regarding their results.
So 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.
The science behind BIA is well researched and validated in peer-reviewed published literature, the most notable being -
- Gomes et al 2017 BIA of body composition
- Meleleo et al 2017 Evaluation of body composition with Bioimpedance
- Raeder et al 2018 Validity of BIA in estimation of FFM in colorectal cancer patients
- Sergi et al 2104 Assessing appendicular skeletal muscle mass with BIA
The basis of the accuracy and repeatability of BIA as a technology relies on 5 factors to ensure absolute integrity, those being -
- Age
- Gender
- Height
- Weight
- Impedance measurement
Another important factor to consider is that there is no such thing as a direct measure of body composition other than in post-mortem by dissection of tissue.
Other than the logic of age and gender being a significant factor in changes of body composition, you should never expect to obtain the same scan result if you change your age and gender on the machine. I have attached some evidence-based information around age for some further clarity.
BIA provides a reliable, un-intrusive, repeatable measure of body composition when conditions are standardized.
This information is really only highlighting one important factor of why the Evolt 360 trumps other brands of body composition machines. The other main features are -
- Owner's Dashboard to view their scans
- Automated Challenge Platform
- Automated Data Analytics Platform
- Tracking App with Calorie and Macronutrient profile estimation
- Customization of Result Sheet to client logo
