The effect of endurance training with crocin consumption on the levels of MFN2 and DRP1 gene expression and glucose and insulin indices in the muscle tissue of diabetic rats.

This study aimed to investigate the effect of crocin consumption, high-intensity interval training (HIIT), and low-intensity continuous training (LICT) and their interactive effect on the gene expression of Mfn2 and Drp1 in the skeletal muscle and serum glucose and insulin indices in high-fat diet (HFD) and streptozotocin (STZ)-induced diabetic rats. Fifty-six adult rats were divided into eight groups of seven subjects: crocin consumption, HIIT, LICT, HIIT with crocin, LICT with crocin, diabetic control, healthy control, and sham (placebo). At the end of the course (5 months), metabolic indices were measured.
