Ms. Westerterp-plantenga et al., Core-skin gradient of body temperature related to non-shivering thermogenesis 3 in humans at a lowered ambient temperature, J THERM BIO, 26(4-5), 2001, pp. 467-472
We addressed the effect of lowered ambient temperatures i.e. 22 degreesC (7
2 degreesF) versus 27 degreesC (81 degreesF) in 8 women and 16 degreesC (61
degreesF) versus 22 degreesC (72 degreesF) in 9 men as part of a 24h non-s
hivering thermogenesis (NST3) measured in it respiration chamber. We define
d this new concept, NST3 as total energy expenditure -(sleeping metabolic r
ate + diet-induced energy expenditure + activity related energy expenditure
). This was 248 +/- 208 kJ/d at 22 degreesC and 714 + 505 kJ/d at 16 degree
sC, and was related to the core-skin body temperature gradient (r = -0.95,
p < 0.001 and r = -0.7; p < 0.05) thus limiting the increase in this gradie
nt at a lower ambient temperature. (C) 2001 Elsevier Science Ltd. All right
