A Pilot Study Validating Select Research-Grade and Consumer-Based Wearables Throughout a Range of Dynamic Exercise Intensities in Persons With and Without Type 1 Diabetes: A Novel Approach

Abstract

Overall, our study demonstrates that current research-grade wearable technologies operate within a ~10% error for both HR and EE during a wide range of dynamic exercise intensities. This level of accuracy for emerging research-grade instruments is considered both clinically and practically acceptable for research-based or consumer use. In conclusion, research-grade wearable technology that uses EE kilocalories · minute and HR reliably differentiates PA intensities.

ISPAD Clinical Practice Consensus Guidelines 2018: Exercise in children and adolescents with diabetes

“…However, recently a study concluded that wearables have acceptable accuracy regarding monitoring of heart rate and energy expenditures. Thus, wearables may be important in the future as exercise then could be evaluated along with carbohydrate intake, insulin doses and glucose values …”

Current progress of photoplethysmography and SPO2 for health monitoring

“…Wearable devices can also be used to monitor the PR of individuals undergoing cardiac rehabilitation [162] and for diabetes management [163].…”

Enhanced Accuracy of Continuous Glucose Monitoring during Exercise through Physical Activity Tracking Integration

“…This implies that some of the signals that were estimated from each of the devices using hidden algorithms might not be reproducible from other raw data, e.g., FME was an energy expenditure estimation by the Fitbit device calculated from its sensors, which can differ from implementations in other devices. In a recent study comparing different research and consumer devices, an error range of 10% was found for heart rate and energy expenditure measurements [20].…”
