Abstract:

Background & aim: Cardiovascular disease is one of the principal causes of mortality in the world. Oxidative stress plays a major role in the development of cardiovascular diseases. Physical activity improves the antioxidant status of the heart tissue. The aim of the present study was to investigate the levels of oxidative and antioxidant indices of the heart tissue of exposed male rats exposed to doxorubicin after eight weeks of severe routine training and consumption of crocin.

 

Methods: In the present experimental study, 50 male Wistar rats with a mean age of 8 weeks and an average weight of 200-220 g were randomly assigned to 5 healthy control groups (saline), doxorubicin (control), doxorubicin crocin, doxorubicin training, and doxorubicin crocin training. The training groups completed the course with two severe periods in the first week and completed 8 severe periods in the last weeks. After 8 weeks, malondialdehyde levels (MDA) and superoxide dismutase (SOD) and catalase (CAT) enzymes activity were measured in cardiac tissue. Data were analyzed by independent t-test, two way ANOVA.

 

Results: Data analysis indicated a significant increase in malondialdehyde level and a significant decrease in the activity of superoxide dismutase and heart catalase in Doxorubicin group compared to healthy control group (p=0.001). Moreover, the results revealed a significant decrease (P=0.001), crocin (p=0.001), and the combination of exercise and crocin (p=0.025), and a significant increase in the activity of superoxide dismutase and catalase. In the result it was found that exercise (p=0.001), crocin (p=0.001), and exercise combinations (p=0.005) showed that in the comparison between the groups, the effect of exercise and crocin alone success. There was no significant difference, but there was a significant difference between their combined effect and the effect of each of these two interventions (exercise and crocin) alone, and these two effects amplified each other (p=0.001).

 

Conclusion: It seems that regular high intensity interval training, supplementation of crocin, or a combination of these two, could be achieved by decreasing levels of oxidative index, malondialdehyde and increased activity of antioxidant enzymes of superoxide dismutase and catalase of heart tissue, protective effects against oxidative damage of doxorubicin have. It appeared that combining these two interventions may have a better preventive and therapeutic strategy than their one-way use.
