Metabolic parameters after stroke. Differences between groups were determined by two‐way ANOVA with Bonferroni post hoc tests at P ≤ 0.05 (two‐tailed). By this criterion, glucose serum levels reached a statistically significant difference by day 14 poststroke in CR vs AL animals (A). By day 14 after stroke, insulin levels significantly increased in aged CR rats as compared to the young and AL animals (B). After stroke, free fatty acid levels decreased significantly in AL animals and by day 14 also in CR animals (C). By day 7, the circulating IGF1 levels significantly decreased in AL aged animals as well as young rats, but not in CR animals (D). *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001.
