Abstract/OtherAbstract:
Streptozotocin-induced insulin deficient rats allowed to run at will had significantly (P less than 0.001) lower mean (+/- SEM) plasma glucose levels (12.1 +/- 0.9 vs 22.6 +/- 1.7 mM/l) than did equally insulin deficient sedentary rats. Muscle glycogen phosphorylase and synthase activities were similar in exercise-trained and sedentary diabetic rats, and were unchanged from control values. In contrast, muscle phosphofructokinase activity was reduced (P less than 0.001) in sedentary rats with insulin deficiency, and the defect was significantly reversed (P less than 0.01) when such rats were allowed to run spontaneously. These results are consistent with the view that the ability of exercise-training to attenuate the magnitude of hyperglycemia in streptozotocin-induced insulin deficiency is associated with an effect on a key regulatory enzyme in the glycolytic pathway.
