As you probably know, smart watches Galaxy Watch4 to Watch5 enable the measurement of body composition. This measurement was previously only available in clinics and gyms, so it begs the question of how accurate it actually is on a watch. The answer has now been given by an American study, according to which the measurement of biological values is on a watch Galaxy Watch4 to Watch 5 reliable and stable, but not as accurate as laboratory measurements.

A team of researchers from Louisiana State University, the Pennington Biomedical Research Center and the University of Hawaii Cancer Center researched, how accurate is the body structure measurement on the watch Galaxy Watch4 to Watch5 and what effect it has on the users who use them. 109 people participated in the study, of which 75 completed the test. Values z Galaxy Watch4 were compared to clinical measurements using a method called dual-energy X-ray absorptiometry (DXA) and duplicate octapolar bioelectrical impedance analysis.

The team found that "bioelectrical impedance analysis (BIA) smartwatches are capable of stable, reliable, and accurate body composition measurements with an accuracy comparable to, but lower than, laboratory measurements." BIA measurement on Galaxy Watch4 to Watch5 had approximately 97 and 98% correlation with the results of the two aforementioned laboratory methods. This means that the BIA values that at Galaxy Watch4 to Watch5 you get are fairly accurate. In addition, the study found that access to such measurements directly on the wrist helped people increase their physical activities.
