Smartwatches often overreport calorie burn
A new study from the University of Florida reveals that some smartwatches exaggerate the number of calories burned by users during workouts, confusing those who rely on this data for weight loss. The researchers tested four smartwatches on 58 adults during 10-minute cycling exercises, finding significant variability in measurement accuracy, with larger errors observed in individuals with higher body fat percentages. The results indicated that some watches, especially those from Fitbit, provided inaccurate readings, making it difficult for users to rely on the numbers to set their goals. The scientists emphasize that while smartwatches remain useful for overall health monitoring, their accuracy in calculating calories burned during strength training is still under investigation.
