The Effect of 8 Weeks of Endurance -Resistance Training and Taurine Supplementation on Osteocalcin and Osteopontin Proteins in Diabetic Wistar Rats with STZ

Osteocalcin and osteopontin are related to diabetes and osteoporosis. The aim was to determine the effect of eight weeks of endurance-resistance training and taurine supplementation on osteocalcin and osteopontin in diabetic male Wistar rats.
In this experimental study,40adult male Wistar rats weighing 250-300grams and 6weeks old were randomly divided into 3 diabetic groups (each group, 10Rat); exercise, supplement and a control and a non-diabetic groups were included as a healthy control group. To make diabetic, 55mg/kg of body weight of streptozocin was injected. Combined exercises were performed for eight weeks and 5times a week. Taurine supplementation was taken as a 1% solution in water daily. One-way ANOVA and Bonferroni's post hoc were used to compare the inter-group and intra-group changes of the variables.
Osteocalcin increased significantly in the diabetic exercise group compared to the diabetic control (P=0.018) and decreased significantly in the diabetic control compared to the healthy (P=0.0001). Osteopontin increased significantly in the diabetic control group compared to the healthy control (P=0.003); While, there was no significant difference in other groups (P=1.000). Body weight and BMI increased significantly in the exercise-diabetic group compared to the diabetic-supplement (P=0.0001). There was a significant decrease in food consumption in the diabetic exercise group compared to the diabetic supplement group (P=0.030).
Eight weeks of endurance-resistance training and taurine supplementation led to an increase in osteocalcin and no change in osteopontin.
