Maternal Moderate Physical Training during Pregnancy Attenuates the Effects of a Low-Protein Diet on the Impaired Secretion of Insulin in Rats: Potential Role for Compensation of Insulin Resistance and Preventing Gestational Diabetes Mellitus
Body weight (a) and food intake (b) during pregestation and gestation by control (C, n = 5), trained (T, n = 5), low-protein diet (LP, n = 5), and trained + low protein dams (T + LP, n = 5). The protocol of physical training was initiated four weeks before pregnancy (5 days per week, and 60 minutes per day). During gestation, duration and intensity of each session of physical exercise were progressively reduced and each group received either 17% casein diet (C and T) or 8% casein (low-protein group, LP and LP + T) isocaloric diet ad libitum. The values are presented as means ± S.E.M. ∗P < 0.05 versus C group using two-way ANOVA and Bonferroni’s post-hoc test.
