University of Michigan study finds Galaxy Watch health measurements impressively accurate | Infinium-tech

Last year, Samsung partnered with the University of Michigan, specifically the Michigan Performance Research Laboratory (MiPR), to study and improve the accuracy of the measurements provided by its Galaxy Watch. Now they’re ready to share their findings.

MiPR studies found a high correlation between the data reported by the Galaxy Watch and sports science reference devices when measuring heart rate, body fat percentage, sweat loss and VO2 max (the last two features were introduced with One UI 4.1). Here are the details:

• heart rate: The study showed that the watch, probably the most used health feature, showed a 90% correlation with an electrocardiogram device while running (which is more difficult to measure while standing, as the watch is constantly bouncing around).
• Body Fat Percentage: Here the watches performed even better, showing a 95% correlation with the standard clinical test of dual-energy X-ray absorptiometry (Dexa,
• Decreased sweating: This is a measure of the amount of water lost by a runner during a race and is used to guide subsequent rehydration. The watches achieved a 95% correlation when tested over distances ranging from 2.5 km to 20 km (1.5-12 miles).
• VO2 max: This measures how much oxygen is absorbed by the body during a workout. Compared to clinical-grade devices, the watches achieved an acceptable correlation of 82%.

“We are excited to continue our partnership with Samsung to ensure that innovations in wearable technology are accessible and accurate for all segments of the population. HPSSSC and MIPR are eager to highlight these excellent results that reinforce our commitment to enhancing heart rate and health monitoring and look forward to future collaborations,” said Kenneth Kozloff, co-director of the HPSSC.
