Phase 2 data. Activity energy expenditure based on combined acceleration and heart rate using group cal (kJ/kg/day); Pwear based on acceleration only signal. Where possible; a specific group equation is derived for that study using data from the IC tests. Where this is not possible; the most appropriate equation from another study will have been applied in the calculation of the group estimated physical activity energy expenditure results. Present for all those who have a valid free-living file i.e file present; no corruptions deemed to affect combined acc and heart rate estimate and >20hrs Pwear(Measured/Derived from or related to Acitheart Monitor/Data )

Present for all those who have a valid free-living file i.e file present; no corruptions deemed to affect combined acc and heart rate estimate and >20hrs Pwear. This variable uses the resting metabolic rate as defined in STANDARD_MET and is the same for every individual(Measured/Derived from or related to Acitheart Monitor/Data )
