The relative contribution to the total energetic cost during 30 min walking of oxygen uptake, lactate production, net arginine phosphate and ATP use

Metabolic componentControlVibrio
Oxygen uptake73.450.3
Lactate production1413.9
Arginine phosphate use4.64.2
ATP use0.70.6
TOTAL 92.7 69.0
  • Values were calculated as μmol ATP equivalents g–1 h–1

    Net use or accumulation was assumed to occur over the entire 30 min walking period. Arginine phosphate and ATP depletion were calculated on a per gram total body mass basis with the assumption that a typical crab contains 25% locomotory muscle mass (Herreid, 1981)
