Final 12 months Samsung partnered with the College of Michigan, particularly the Michigan Efficiency Analysis Laboratory (MiPR), to research and enhance the accuracy of measurements supplied by its Galaxy Watches. Now they’re able to share their findings.
The MiPR research discovered excessive correlation between the info reported by the Galaxy Watches and sport science reference gadgets when measuring coronary heart charge, physique fats proportion, sweat loss and VO2 max (the final two options had been launched with One UI 4.1). Right here’s the breakdown:
- Coronary heart charge: in all probability essentially the most generally used well being characteristic on a watch, the research confirmed a 90% correlation with electrocardiogram gear when operating (which is trickier than measuring when standing nonetheless for the reason that watch bounces round always).
- Physique fats proportion: right here the watches did even higher, displaying a 95% correlation with the usual diagnostic check of dual-energy X-ray absorptiometry (DEXA).
- Sweat loss: it is a measurement of the quantity of water a runner has misplaced throughout their run and is used to information rehydration afterwards. The watches achieved 95% correlation when examined on distances starting from 2.5km to 20km (1.5-12 miles).
- VO2 max: this measures how a lot oxygen is absorbed by the physique throughout a exercise. In comparison with clinical-grade gear, the watches achieved a suitable correlation of 82%.
“We’re excited to proceed our partnership with Samsung to make sure that improvements in wearable know-how are accessible and correct throughout all segments of the inhabitants. HPSSC and MiPR are desirous to unveil these excellent outcomes that solidify our dedication to enhancing coronary heart charge and well being monitoring and are trying ahead to future collaborations,” mentioned Kenneth Kozloff, HPSSC co-director.
