Changes in Core Temperature and Thermoeffector Thresholds in Exercise-Trained Rats

摘要: Spontaneous running in a wheel has emerged as an alternative method of exercise small animals. The present study investigated how training with affects core temperature level and thermoeffector thresholds rats. Female rats were allowed to run freely the for 6 months. Sedentary controls did not during same period. After period, they loosely restrained their threshold temperatures tail skin vasodilation cold-induced thermogenesis determined by warming or cooling animals use chronically implanted intravenous thermode. Resting exercise-trained higher than those sedentary controls. results suggest that rat, shifts heat loss production high levels, which may result rise level.
