Aim: Although obesity is becoming epidemic all around the world, the effort to reduce its prevalence has not been effective. Thus, there is a need to find further paths to prevent obesity. The aim of this study was to determine the effect of endurance training and adenosine on the A1AR gene expression in the visceral adipose tissue of obese male rats Method: Twenty wistar strain male rats were fed with high-fat food for twelve weeks and reached the average weight of 319+-30 grams. The rats were divided randomly into four groups after being conformed. The exercise training session included running on the treadmill with no slope for 12 week. Each week, five sessions were held for 15-31 minutes with the speed of 20-25 meters per minute. In order to measure the relative gene expression of A1AR, the PCR method was used. The data was analyzed using the statistical method of two-way analysis of variance. Results: both variable of endurance training and adenosine consumption (independently) demonstrated a significant decrease in the A1AR gene expression in the visceral adipose tissue. (P=0.001). Also, the intraction of training and adenosine affects significant reduction of the A1AR expression. Conclusion: Endurance training and adenosine are strong stimulants of adipose tissue lipolysis as A1AR antagonists and have the potential to be used as effective lipolysis agents in obesity Keywords: Endurance Training, A1AR, Visceral White Adipose Tissue.

Aim: Effect of zizyphus jujube extract and resistance exercise on liver damaging biomarkers in male rats toxicated by anabolic steroid. Method: 42 Wistar rats were randomly divided into six equal groups: group 1: control, group 2: sham, group 3: anabolic steroid (5 mg/kg), group 4: anabolic steroid (5 mg/kg) + zizyphus jujube extract (600 mg/kg), group 5: anabolic steroid (5 mg/kg) + resistance exercise, and group 6: anabolic steroid (5 mg/kg) + zizyphus jujube extract (600 mg/kg) + resistance exercise. Apart from the control and sham groups, anabolic steroid with a 5 mg per kg dose was injected to other groups once a week. The resistance exercise protocol were consisted of three exercise sessions per week by 5 repetitions in 3 sets of climbing ladder for eight weeks. The data were analyzed by the SPSS software, using ANOVA. Results: The results of this study revealed a significant increase in liver enzymes (ALT, AST, and ALP) and direct and total bilirubins in the anabolic steroid group (group 3) compared to the control and sham groups (p < 0.05). In addition, zizyphus jujube treatment (group 4), resistance exercise (group 5), and treatment with resistance exercise (group 6) caused a significant decrease in liver enzymes (ALT, AST, and ALP) and direct and total Bilirubins. There were no-significant differences in albumin concentration between experimental groups Conclusion: : Zizyphus jujube extract consumption as well as resistance exercise caused a significant decrease in liver damaging biomarkers. Hence, the simultaneous use of resistance exercise and zizyphus jujube extract did not show any increasing effect on these biomarkers.
