Thermoregulatory heat production in man: prediction equation based on skin and core temperatures

equation based on skin and core temperatures. J. Appl. Phys-iol.: Respirat. Environ. Exercise Physiol. 42(3): 377-384, 1977.-The relationship of metabolic rate to skin and core temperatures was measured in eight subjects cooled in 10°C water. Reference core temperatures, based on the tympanic and rectal sites, were 41.0 and 41.4”C, respectively. Refer-ence mean skin temperatures were 41.8 and 42.2”C when determined in relation to tympanic and rectal temperatures, respectively. These results enabled construction of equations for predicting the steady-state metabolic rate (MR, W l kg-‘) of nonexercising man according to thermal inputs from the skin (T,,) and core (TtJ. or Trt) MR = 0.0356(Tsk- 41.8)(T,,.- 41.0
