SEOUL, Sept. 4 (Korea Bizwire) – Samsung Electronics announced on September 4 that the health data collected by its Galaxy Watch has been validated for accuracy in a collaborative study with the Human Performance and Sports Science Center (HPSSC) at the University of Michigan.
According to Samsung, the HPSSC simultaneously measured indicators such as heart rate, estimated sweat loss, maximum oxygen uptake, and body fat percentage using both the Galaxy Watch and professional clinical research equipment. The study found a significant correlation between the two data sets in terms of accuracy.
In an experiment measuring heart rate accuracy during running, the heart rate measured by the Galaxy Watch worn by test subjects showed a 90% correlation with measurements from professional ECG equipment used to monitor heart beats.
When comparing estimated sweat loss measurements for various running distances from 2.5km to 20km, the Galaxy Watch measurements showed a 95% correlation with professional equipment. Estimated sweat loss is an indicator of how much fluid should be consumed during or after exercise.

The Galaxy Watch’s measurements of maximum oxygen uptake, which is used to set exercise goals appropriate to an individual’s fitness level, showed an 82% correlation with professional equipment. This metric measures the amount of oxygen the body absorbs during exercise.
Body fat percentage data from the Galaxy Watch demonstrated a 95% correlation when compared to measurements from a DEXA body composition analyzer, which is the standard equipment for body composition analysis.
Park Heon-soo, head of the Digital Health Team in Samsung Electronics’ MX division, said, “Through collaboration with University of Michigan researchers, who have outstanding expertise in health and sports, we have once again confirmed the accuracy of the Galaxy Watch. We will continue to provide more accurate and innovative fitness experiences.”
