Today, people are incorporating healthier lifestyles into their daily routines. One of the measurements of your physical form is your BMI. The BIA (Bioelectric Impedance Analysis) is a much better metric, though. It was previously only available in clinics and gyms, but can now be measured right from your wrist using the Galaxy Watch 4 or the Galaxy Watch 5.
A team from Louisiana State University, Pennington Biomedical Research Center, and the University of Hawaii Cancer Center collaborated to determine how accurate the body composition measurement on the Galaxy Watch 4 and Galaxy Watch 5 is and what impact it has on users who use it. The study recruited 109 people, of which 75 completed the test. The readings from the Galaxy Watch 4 were compared with the clinical measurements using an energy X-ray absorptiometry (DXA) scan and a duplicate laboratory-grade octapolar bioelectrical impedance analysis.
In conclusion, it was found that “smart-watch BIA devices are capable of stable, reliable, and accurate body composition measurements, with precision comparable to but lower than that of laboratory measures.” The BIA measurements on the Galaxy Watch 4 and Galaxy Watch 5 had approximately 97% and 98% correlation with the results from the two reference methods using laboratory measures. It means that the BIA readings that you are getting on the Galaxy Watch 4 or Galaxy Watch 5 series smartwatches are fairly accurate.
The study also found that having access to such measurements right on their wrists helped people amp up their physical activities.
You can take some additional steps to improve the accuracy of measurement at your end. Samsung advises using the BIA measurement at the same time of the day, on an empty stomach, after going to the bathroom, when you are not having a menstrual period, before doing exercise, and after removing metal objects from your body.
