title: Effect of running training on brown adipose tissue activity in rats: a reevaluation.
abstract: The effect was investigated of running training on the thermogenic activity of brown adipose tissue (BAT) in rats. The exercised rats were trained on a rodent treadmill for 5 days per week and a total of 9 weeks. After the training, a significantly lower rate of increase in body weight was found, suggesting some training effect, whereas the training failed to induce a decrease in BAT mass. As previously reported (Yamashita, Yamamoto et al., 1993), there was also a markedly lower expression of uncoupling protein (UCP) mRNA in BAT from trained rats; nevertheless, no definite effect of the running training was noted on either UCP content or guanosine 5'-diphosphate binding in the mitochondria recovered from BAT. The results obtained suggest that running training has no overt effect on the thermogenic activity of BAT in rats.
