The participation of shivering and nonshivering thermogenesis in warm and cold-acclimated rats

Rearing mice at 22°C programs increased capacity to respond to chronic exposure to cold but not high fat diet

“…Both groups mounted similar acute responses to an 8 °C decrease in T a . This supports the idea that systems regulating shivering and thermogenic capacity at baseline [ 3 , [29] , [30] , [31] ] are not impacted by rearing temperature.…”

Antioxidative defence alterations in skeletal muscle during prolonged acclimation to cold: role ofl-arginine/NO-producing pathway

“…Thus, the accelerated increase in MnSOD, CuZnSOD and CAT activities observed here in L-arginine-treated rats during the early acclimation to cold could be connected to improved skeletal muscle contraction and oxidative capacity by NO and, consequently, to O 2 · -and H 2 O 2 production. However, after a period of 7 (Cannon and Nedergaard, 2004) or 10 days (Peralta et al, 2003) on cold, the impact of shivering decreases and cannot account for thermogenesis (Griggio, 1982), while NST markedly increases. During prolonged exposure to cold, despite decreased shivering, skeletal muscle retains an enhanced capacity for aerobic support of energy metabolism (although, less than in shivering), i.e.…”
