Male Wistar rats, aged 6 weeks were maintained at 25°C for 9 to 11 weeks (W grop), at 10°C for 9 to 11 weeks (C group), and at 25°C for 2 weeks after exposure to 10°C for 9 weeks (D group). Thermogenesis at 10°C was significantly greater than at 25°C. Thermogenesis per body mass in the C group was greater than in the W and D groups. The RQ value at 10°C was greater than at 25°C in the W group, whereas the opposite was observed in the C and D groups. It is suggested that a large part of enhanced thermogenesis, caused by cold acclimation for 9 weeks, is lost because of a decreased secretion of calorigenic hormones, in spite of a slight decrease in BAT mass, during deacclimation for 2 weeks.
