Comparison of Physical Activity Sensors and Heart Rate Monitoring for Real-Time Activity Detection in Type 1 Diabetes and Control Subjects

n=17 total, including 9 healthy control subjects (4 males, 37.4±12.7 years old, BMI 24.8±3.8 kg/m2, fasting plasma glucose 4.71±0.63 mmol/L) and 8 patients with type 1 diabetes (6 males, 45.2±13.4 years old, BMI 25.1±2.9 kg/m2, fasting plasma glucose 8.44±2.31 mmol/L).

Physical activity quantified from accelerometers (acceleration units [AU]) during a standardized activity protocol.

Physical activity quantified from heart rate (HR) monitors during the same standardized activity protocol.
