La tasa metabólica basal (TMB) es la tasa de gasto energético por unidad de tiempo de los animales endotérmicos en reposo. [1] Se informa en unidades de energía por unidad de tiempo que van desde vatios (joule/segundo) a ml O 2 /min o joule por hora por kg de masa corporal J/(h·kg). La medición adecuada requiere que se cumpla un estricto conjunto de criterios.
