Abstract
Background: NRF1 and TFAM are proteins that affect mitochondrial biogenesis and play an important role in diabetes. The aim of the present study was to investigate the effect of high intensity training (HIT) training and beetroot consumption on NRF1 and TFAM in visceral adipose tissue of aged type 2 diabetic rats.
Method: In this experimental study, 40 male rats (weight range 270-300 grams and age 12-14 weeks) diabetic with streptozotocin were randomly divided into 5 groups (healthy control, diabetic control, supplement, exercise, exercise + complement) were divided. The training groups were subjected to intense interval training with an intensity of 50 to 90% of the maximum speed for 4 weeks and 4 sessions each week and 44 minutes each session. The groups receiving the supplement received 10 mg of beetroot per kilogram of body weight daily for 4 weeks and 4 times a week orally. The data are statistically significant using two-way ANONA test and (P < 0.05) was evaluated.
Results: The results of the study showed that the induction of diabetes led to a significant decrease in the protein levels of NRF1 and TFAM, so that in the exercise group, beetroot had a significant effect on the changes of NRF1 in the visceral fat tissue of elderly rats with diabetes. (P=0.001), but the interaction of HIT training and beetroot supplement in NRF1 changes is not significant (P=0.56) and also the factor of exercise and beetroot supplement, as well as the interaction of HIT training and beetroot also has a significant effect on TFAM changes in visceral adipose tissue of elderly rats with diabetes. (P=0.001).
Conclusion: Based on the findings of the present research, it seems that high interval training with beetroot consumption can lead to an increase in NRF1 and TFAM gene expression and thus help to improve and control diabetes in the elderly.

Abstract
Background: The purpose of the research was to compare the effect of two types of aerobic exercise—with and without incline—on the modulation of oxidative stress and kidney function in chronic kidney disease (CKD) mice.
Methods: A total of 24 two-month-old female C57b16 mice weighing 25±26.1 grams, were randomly divided into four groups: healthy control, CKD-affected mice, CKD mice undergoing aerobic exercise without incline, and CKD mice undergoing aerobic exercise with incline. To induce CKD, they received adenine powder at a concentration of 0.2% mg/kg for four weeks. The training groups performed eight weeks of treadmill training (five sessions per week), whit one group exercising on a 20-degree incline and the other on a zero-degree incline. After the last training session, blood samples were collected to measure blood urea nitrogen, urea and glutathione concentration using the ELISA method. The expression levels of the SIRT1, NRF1 and TNF-α genes were measured using qPCR (Real-Time PCR) technique. For statistical analysis, a one-way ANOVA test and Tukey's post hoc test were employed, with a significance level set at P≤ 0.05.
Results: The results showed that the induction of CKD caused a significant increase in blood urea nitrogen and a significant decrease in glutathione concentration compared to the healthy control group (P< 0.05). Conversely, in the exercise groups, there was a significant increase in glutathione concentration and a significant decrease in blood urea nitrogen (P< 0.05). The expression level of SIRT1 and NRF1 in the slope training group increased significantly, while the expression level of TNF-α decreased significantly (P< 0.05).
Conclusion: Exercises performed on an incline moderates oxidative stress through the TNFα/SIRT1/NRF1 signaling pathway, improving glutathione concentration and blood urea nitrogen levels in mice with chronic kidney disease. Furthermore, the effects of incline exercise were found to be superior to those of exercise without incline.
