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.
