Table 2 Metabolic rate during sitting activities and slow walking for the sample as a whole, and for the healthy weight and obese groups separately. Standard MET values and the mRMR values are shown, along with the results of the independent t-tests comparing MET values between healthy weight and obese participants

From: Energy expenditure during common sitting and standing tasks: examining the 1.5 MET definition of sedentary behaviour
