Abstract
Aim: This research investigated the effect of high intensity interval training (HIIT) and melatonin supplementation on oxidative stress markers, antioxidant enzyme activity, creatinine (Cr) and blood urea nitrogen (BUN) concentrations, as well as histopathological changes to evaluate kidney function in male rats with ischemia renal reperfusion. Methods: 30 male Wistar rats were randomly divided into 5 groups, healthy, Ischemia/Reperfusion (IR), IR + intense interval training, IR + melatonin supplement and IR + high intensive interval training + melatonin supplement. Except for the healthy group, the animals were subjected to ischemia-reperfusion. The HIIT protocol was implemented for 12 weeks (5 days per week). Oxidative indicators of SOD, GPX and MDA were measured by spectrophotometric method and for BUN and Cr indicators; urea was quantitatively detected by Urease-GLDH and creatinine by JAFFE method in plasma serum using photometric method. Because of normal distribution of parameters, the data were analysed by one-way analysis of variance and comparison test of two populations at significance level of (p<0.05). Results: A decrease in kidney function after IR was observed with an increase in Cr, BUN and MDA levels and a decrease in GPX and SOD (P < 0.05). Melatonin consumption decreased BUN, Cr and MDA and increased SOD, GPX (P < 0.05) compared to the ischemic group. In the intense interval training group, BUN decreased and GPX increased compared to the ischemic group (P<0.05). Performing intense interval training along with melatonin supplementation decreased BUN and Cr levels and increased SOD and GPX levels (P < 0.05). The histopathological results showed that intense interval training along with melatonin consumption had the least damage to the kidney tissue. Conclusions: The high-intensity interval training and melatonin supplementation are effective in protecting kidney tissue against apoptotic damage and inflammation caused by renal ischemia.
