 note = {application, In order to knwon a mechanisms of improved thermogenesis to cold in exercise-trained men, 20 nude male subjects (10 non-exercise control group and 10 exerise trained group) were exposed to 10℃ for 60 min. The changes of thermogenesis, plasma catecholamine, corticostroid hormones, glucose, and free-fatty acids levels were studied. Energy metabolic rate was elevated to 14.4±1.2 kcal/m^2/hr and 18.9±2.0kcal/cm^2/hr after 10℃ exposure in control and trained groups, respestively. Energy metabolic rate was also greater in trained group than in control. Then, respiratory exchange ratio(RER) was higher in trained than in control. However, plasma catecholamine increments to cold exposure did not differ between in trained and in control. When exposed to cold, plasma norepinephrine(NE) and epinephrine increments was significantly elevated in both groups. Blood glucose concentration during acute cold exposure was less in control than in trained. Also, mean skin temperature during cold exposure was higher in trained than in control. On the other hand, plasma cortisol levels of trained and control did not differ significantly during cold exposure period. There was a positive correlation between the increase in plasma cortisol and those inenergy metabolism after cold exposure. Also, there was a correlation between the decrease of blood glucose and the increase in energy metabolism to cold exposure. Our results, also show that exercise training: 1) dose not suppress NE-dependent non-shivering thermogenesis. 2) was greater the metabolie sensitivity of plasma cortisol. 3) was greater the utilization of glucose.},
