Effect of Interval and Continued Exercises with Crocin on Bax/Bcl-2 in Diabetic Obese Rats

Diabetes is a metabolic disease which is linked to increased physical disabilities and muscle tissue damage. The aim of this study was to investigate the effect of interval and continued exercises with crocin on Bax/Bcl-2 ratio in diabetic obese rats.

In this clinical trial study, 56 adult diabetic rats (high-fat diet and venous injection of streptozotocin) were selected and randomly assigned to groups (1), intense interval exercises (2), low intensity exercise (3), intense interval exercise with crocin consumption, (4) Low intensity exercise with crocin consumption, (5) Crocin consumption, (6) sham and (7) control were divided. Intense interval and low intensity exercise groups lasted for 8 weeks, three sessions per week, with intensity of 80 to 85 and 50 to 55 percent of maximum treadmill running, and crocin consumption groups for 8 weeks per day, mg / kg 25 crocin were taken peritoneal. To analyze the research hypotheses, Kolmogorov- Smirnov tests, independent T- tests and two-way multi-variable analysis of variance were used along with Benferron's comparison method. It should be noted that the significance level in all measurements was considered to be P-value≤ 0.05.

Results showed that exercise (P-value: 0.12) and crocin (P-value: 0.10) consumption had no significant effect on Bax/Bcl-2 gene expression in diabetic rats. Also interaction of exercise and crocin consumption on Bax/Bcl-2 was not significant (P-value: 0.12).

It appears that exercise and crocin consumption have not interaction effect on improvement of Bax / Bcl-2 ratio in diabetic rats.
