Abstract
Background: The relationship between low PGC-1α expression and several metabolic diseases such as diabetes and obesity has been identified. This study investigates the effect of eight-week high intensity interval training (HIIT) and caffeine intake on mitochondrial biogenesis in soleus muscle in diabetic rats induced Streptozotocin.
Methods: In a clinical-interventional animal study, 50 male rats were randomly assigned to 5 equal groups (control group(C), diabetes group(D), diabetes + caffeine group(D+Caf), diabetes + training group(D+T), diabetes + training + caffeine group(D+CAF+T)) and subjected to 8 weeks of caffeine supplementation (70 mg / kg of caffeine powder was injected five days each week) and 8 weeks of 5 sessions per week with 6 to 12 times, 2-min intervals with intensity of 85-90% of maximal speed. Blood was collected directly from the left ventricle to measure blood glucose levels. The soleus muscle of the left leg was extracted and PGC-1α measured by Western Blot method. Independent t-tests, two-way analysis of variance, and Eta squared (p <0.05) were used to analyze the data.
Results: The results showed that induction of diabetes significantly increased blood glucose (P <0.01) and significantly decreased mRNAPGC-1α (P = 0.002). Also, both high-intensity interval training (p = 0.001) and caffeine supplementation (p = 0.03) significantly increased mRNAPGC-1α.
Conclusion: Based on the results of this study, it is possible to suggest the use of HIIT and caffeine consumption as an effective intervention in increasing mitochondrial biogenesis in diabetics. However, a clear statement in this regard requires further research in this area.

Abstract
Background: The health and proper functioning of the endoplasmic reticulum in the liver can lead to an increase in the quality of the metabolism of liver cells. Exercise can lead to liver health by regulating liver enzymes and factors related to apoptosis pathway. Therefore, the aim of the current research is to compare the performance of the endoplasmic reticulum chaperone protein of the liver of healthy model rats with the intervention of different training sessions and starvation.
Methods: In this experimental research, 30 Wistar male rats with a weight range of 330 ± 25 grams were selected and divided into six groups: 1) control, 2) starvation, 3) 3 days of training per week, 4) 5 days of training per week, 5) starvation + 3 training days per week, 6) starvation + 5 training days per week. Training consisted of one hour of continuous running on a treadmill for 4 weeks, and starvation was performed for 14 hours when the rats were awake. Data analysis was performed using one-way analysis of variance and post hoc LSD statistical tests in SPSS version 23 software. A significance level of P≤ 0.05 was considered.
Results: Data analysis showed a significant change in the levels of liver enzymes alanine aminotransferase (ALT) and aspartate transaminase (AST) (P≤ 0.05). This change in CHOP gene expression was also significant (P≤ 0.05).
Conclusion: Aerobic training for 3 and 5 days with starvation can lead to liver health by reducing liver enzymes (AST and ALT) and cell death-related factor (CHOP) through the apoptosis pathway.
