Plasma Insulin and Glucose at the Transition from Maintenance to Relapse. Plasma insulin (A) and glucose (B) on day 0 and day 1 of relapse were examined by repeated measures ANOVA for the effects of diet (RS), exercise (EX), time, and their interaction. Exercise potentiated the increase in insulin on day 1, an effect that was attenuated by dietary RS. Plasma glucose was not affected by time, but on day 1 of relapse glucose levels tended to be lower in RS-fed rats (p = 0.07).
