standard metabolic rate


Also found in: Acronyms.

standard metabolic rate (SMR)

the metabolic rate of a resting post-absorptive animal in a darkened chamber at a specified environmental temperature. For tachymetabolic animals SMR is BASAL METABOLIC RATE plus REGULATORY HEAT PRODUCTION Units: cm3 O2 h-1.
