Table 4 Absolute increase in energy expended, oxygen (O2) consumed, carbon dioxide (CO2) and heat produced (Hprod), and water required for hydration, during 30-d and 1,080-d missions resulting from the increase in body size alone between a ‘small-sized’ (1.50-m) and ‘large-sized’ (1.90-m) male crew, and the use of countermeasure (CM) exercise.
