MET score = (Activity V̇O2 mL·kg-1 min-1)/(Individual Resting V̇O2 mL·kg-1 min-1).
All accelerometer (Actigraph) values are the mean of right and left hip accelerometer counts; counts per 30 seconds are not necessarily half of the counts per minute because consecutive 30-s periods do not always have identical counts.
