"Body Composition Measurements by Galaxy Watch 4 Show 98% Agreement with Equipment Values"

[Asia Economy Reporter Cha Min-young] A study has found that the body composition measurement accuracy of Samsung Electronics' Galaxy Watch is comparable to that of professional measuring devices.

According to the industry on the 15th, the Pennington Biomedical Research Center at Louisiana State University and the Cancer Center at the University of Hawaii recently published a paper titled "Accuracy of Body Composition Measurement by Smartwatches," which revealed that the body composition values measured by the Galaxy Watch4 showed a high correlation with those measured by clinical standard body composition measurement equipment (DXA) and bioelectrical impedance analysis (BIA) devices. This paper was recently published in the American Journal of Clinical Nutrition (AJCN), a renowned journal in the field of biology and medicine.

The two universities conducted a study involving a total of 75 participants, including 34 men and 41 women aged 23 to 55, measuring six body composition items with the Galaxy Watch4: ▲body fat mass ▲body fat percentage ▲lean body mass ▲skeletal muscle mass ▲basal metabolic rate ▲body water content, and then comparing these measurements with those from professional measuring devices.

As a result, the correlation between the body composition values measured by the Galaxy Watch4 and the professional measuring devices ranged from a minimum of 93% to a maximum of 98%.

The Galaxy Watch4 and Watch5 are equipped with body composition (BIA) measurement functions. Users of these products can measure their body composition using a total of four electrodes: two buttons located on the side and two on the back.

After wearing the watch, if the user places two fingers on the side buttons for about 15 seconds, the 'Samsung BioActive Sensor,' which supports the body composition function, captures a total of 2,400 data points to measure body fat mass, skeletal muscle mass, basal metabolic rate, and more.

Until now, body composition measurements could only be taken using specialized BIA equipment at medical institutions or clinics, but users of the Galaxy Watch4 and Watch5 can measure their body composition anytime and anywhere directly from their wrist to track their physical and health status.

Additionally, through the Samsung Health application (app), users can manage their personal health in more detail, such as weight loss and muscle mass increase, as well as receive motivation for health management.
