Final 12 months Samsung partnered with the College of Michigan, particularly the Michigan Efficiency Analysis Laboratory (MiPR), to examine 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 information reported by the Galaxy Watches and sport science reference units when measuring coronary heart charge, physique fats share, sweat loss and VO2 max (the final two options have been launched with One UI 4.1). Right here’s the breakdown:
- Coronary heart charge: in all probability probably the most generally used well being function on a watch, the examine confirmed a 90% correlation with electrocardiogram tools when operating (which is trickier than measuring when standing nonetheless for the reason that watch bounces round always).
- Physique fats share: 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 tools, the watches achieved an appropriate correlation of 82%.
“We’re excited to proceed our partnership with Samsung to make sure that improvements in wearable expertise 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.
