Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'ObjectivesThere is considerable promise for using commercial wearable devices for measuring physical activity at the population level. The objective of this study was to examine whether commercial wearable devices could accurately predict lying, sitting, and different physical activity intensity in a lab based protocol. MethodsWe recruited a convenience sample of 46 participants (26 women) to wear three devices, a GENEActiv, and Apple Watch Series 2, a Fitbit Charge HR2. Participants completed a 65-minute protocol with 40-minutes of total treadmill time and 25-minutes of sitting or lying time. Indirect calorimetry was used to measure energy expenditure. The outcome variable for the study was the activity class; lying, sitting, walking self-paced, 3 METS, 5 METS, and 7 METS. Minute-by-minute heart rate, steps, distance, and calor' .
