In a significant validation of wearable technology, a recent study by the University of Michigan’s Human Performance & Sport Science Center (HPSSC) has confirmed the high accuracy of Samsung’s Galaxy Watches in tracking various fitness metrics. Conducted in partnership with Samsung, the research tested the Galaxy Watch 4 and newer models, yielding impressive results that underscore the reliability of these devices in monitoring physical activity.
Key Findings:
- Heart Rate Tracking: The study revealed a remarkable 90% correlation between Galaxy Watches and electrocardiogram (ECG) equipment while running, considered the gold standard for heart rate measurement. This indicates that Galaxy Watches provide highly accurate heart rate tracking, a crucial metric for athletes and fitness enthusiasts.
- Sweat Loss Tracking: Galaxy Watches demonstrated a 95% correlation with clinical measurements over varying workout distances, ranging from 2.5 km to 20 km. This high level of accuracy ensures that users can rely on their Galaxy Watch to track sweat loss and optimize their hydration strategies.
- Body Fat Percentage Tracking: The HPSSC’s Michigan Performance Research Laboratory (MiPR) found a 95% correlation between Galaxy Watches and dual-energy X-ray absorptiometry (DEXA), a highly accurate method for measuring body fat percentage. This validates the ability of Galaxy Watches to provide precise body composition tracking.
- VO2 Max Tracking: The study showed an 82% correlation between Galaxy Watches and clinical medical equipment in measuring VO2 max, a key indicator of cardiovascular fitness. While not perfect, this level of accuracy is considered acceptable and demonstrates the potential of Galaxy Watches in tracking this important metric.

Implications and Future Directions:
The HPSSC study highlights the significance of wearable technology in fitness tracking and the importance of accuracy in these devices. Kenneth Kozloff, HPSSC co-director, emphasized the center’s commitment to enhancing heart rate and health monitoring through innovative partnerships like the one with Samsung.
While the study didn’t specify which Galaxy Watch models were used, it’s likely that the Galaxy Watch 7 and Watch Ultra, with their upgraded health sensors, offer even better performance. As wearable technology continues to evolve, we can expect even more accurate and comprehensive fitness tracking capabilities from devices like Galaxy Watches.
