Label

% tme spent btwn 1.5-3MET grp calibration

Description

Phase 2 data. Fraction of time spent between 1.5-3METs (rmr); acceleration and heart rate using group calibration. 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. This variable uses the resting metabolic rate calculation individualised for each person from the Oxford2005 equation. Equation used is indicated in GROUP_EQUATION. 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 )
