Samsung has teamed up with the University of Michigan’s Center for Human Performance and Sports Science (HPSSC) to evaluate the capabilities of the company’s smartwatch in measuring physical activity and health. The comparison was carried out with reference devices.
To illustrate the experiment, the data from the smartwatch was compared with the indicators of professional devices for measuring heart rate, body fat percentage, sweat loss and maximum oxygen consumption (VO2 max). As a result, a high correlation of the data obtained was recorded:
- heart rate showed a 90 percent correlation between the data from the watch and the equipment for taking an electrocardiogram while running;
- when measuring sweat loss at distances from 2.5 to 20 km, it was possible to record a correlation of 95%;
- in the case of measuring the amount of oxygen absorbed by the body, the Galaxy Watch was 82% accurate compared to clinical-grade equipment;
- measuring body fat percentage with the Galaxy Watch showed 95% accuracy compared to the results of dual-energy X-ray absorptiometry (DEXA).
“We are excited to continue our partnership with Samsung to ensure that innovations in wearable technology are accessible and accurate to all segments of the population,” said Kenneth Kozloff, co-director of HPSSC.
