Abstract :

In addition to their therapeutic purposes, steroids have been abused a lot and have had many side effects. Therefore, this study aims at investigating the effect of eight weeks of aerobic exercise on structural and biochemical changes in the heart tissue of male Wistar rats receiving therapeutic dosages and abuse of Boldenone steroid. Therefore, 49 male rats with 12 weeks of age and 190 g mean weight were divided into 7 groups: control group, sham, therapeutic dosage (2 mg / kg), abuse dosage (5 mg / kg), aerobic exercise, aerobic exercise + therapeutic dosage and aerobic exercise + abuse dosage. Injections were given in the same day of the week on the back of rats with a graduated insulin syringe and placebo was used. The aerobic protocol included running five days a week for eight weeks on a rodent treadmill at a speed of 30 meters per minute and 60 minutes training. The samples were first anesthetized and blood and tissue samples were transferred to the relevant laboratories. The results were also analyzed by SPSS software and one-way analysis of variance and Bonferroni post hoc test with a significance level of 0.05. The results showed that there was no significant difference between the groups in final weight gain and cardiac troponin (p <0.05). Also, plasma testosterone levels in steroid-receiving rats decreased significantly in both therapeutic and abusive dosages compared to the exercise groups (p <0.05). On the other hand, the amount of running distance in rodent aerobic function test in steroid and exercise groups was significantly higher than other groups (p <0.05). Generally, data showed that aerobic exercise can prevent the reduction of endogenous testosterone but it has no effect on cardiac troponin levels and rat weight. In addition, Boldenone steroid appears to be effective on increasing the aerobic function of rats.
