Experimental details

1. Energy Intakes
Energy intakes were calculated from individual dietary surveys.

2. Energy Costs of Activities
Energy costs of activities were calculated by indirect calorimetry using Douglas bags and analysing the O2 and CO2 contents of exhaled air. Measurements were obtained under basal conditions, at rest and at work.

3. Energy Expenditures
Energy expenditures were calculated using time-motion techniques and the average energy cost of work.
