Introduction: Taking anabolic steroids can affect the state of oxidative stress in different tissues of the body such as kidneys. This study aimed to examine the effect of 8 weeks of resistance training with testosterone enanthate consumption on tissue oxidation indicators in male rats. Methods: In the current experimental study, 18 rats with an average weight of 250 ± 50 g were divided into 3 groups of 6 animals including: (1) control, (2) training, and (3) training + testosterone. Rats in the training and training + testosterone groups underwent resistance training for 8 weeks and 5 sessions per week. Also, rats in the training + testosterone group received 20 mg/kg of testosterone enanthate by intramuscular injection 3 days a week. The resistance training protocol consisted of climbing a 1-meter ladder 5 days a week (4 sets of 6 with a rest interval of 60 to 90 seconds) in which the weights were 60% of the rats’ body weights in the first week, and 20% of the body weight was added to the weights every week. One-way analysis of variance was used to analyze the research findings (P≤0.05). Results: Glutathione peroxidase (GPx) level in the training + testosterone group was significantly lower than the control group (P=0.007); however, there were no significant differences in malonaldehyde (MDA) (P=0.64) and superoxide dismutase (SOD) (P=0.29) levels between the research groups. Conclusion: It seems that testosterone consumption can be effective in increasing oxidative stress factors in the kidney tissue of resistance-trained rats.

SARS-COV-2 is the novel type of beta coronavirus that was first seen in December 2019 in Wuhan, China. Type 2 Diabetics are one of the groups most vulnerable to SARS-COV-2 and its associated complications. Many factors such as medication, pathophysiologic-induced compensatory mechanisms, and alterations in protein expression and immune system function can all contribute to severe outcomes in diabetics. In this review article, we first described the possible mechanisms of increased risk and more severe complications rate of SARS-COV-2 in diabetic patients. Secondly, we discussed the crucial roles of exercise in diabetic patients and in balancing of RAS system (ACE2/ACE). Finally, we showed the possible roles of acute and chronic exercise in reducing SARS-COV-2 severe outcomes in diabetics in accordance with the latest evidence. We concluded that regular exercise (especially moderate-intensity exercise) can play immune enhancing, anti-inflammatory, anti-oxidation roles and can balance ACE2/ACE ratio (decreasing ANG2 levels) in diabetic subjects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
