Final yr 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 fee, physique fats proportion, sweat loss and VO2 max (the final two options have been launched with One UI 4.1). Right here’s the breakdown:
- Coronary heart fee: most likely essentially the most generally used well being function on a watch, the examine confirmed a 90% correlation with electrocardiogram gear when working (which is trickier than measuring when standing nonetheless because the watch bounces round continuously).
- Physique fats proportion: right here the watches did even higher, exhibiting a 95% correlation with the usual diagnostic take a look at 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 an appropriate 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 desperate to unveil these excellent outcomes that solidify our dedication to enhancing coronary heart fee and well being monitoring and are wanting ahead to future collaborations,” stated Kenneth Kozloff, HPSSC co-director.
