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.

AbstractAim: The purpose of this study was to examine the effects of progressive interval training on serum testosterone to cortisol ratio in elite male karate athletes.
Method: Fourteen healthy, physically active males karateka with aged 20.36±3.43 yr, height: 175.71±5.96 cm, weight: 73.43±5.76 kg were recruited for participation in this study. All subjects trained three days a week for five weeks. The intensity and duration of exercise increased from first to fourth weeks and then return to the level of beginning in the fifth week (taper). To identify the level of testosterone and cortisol at rest and after exercise, 10 ml venous blood samples were collected before and immediately after exercise at the beginning of first week and at the end of fourth and fifth weeks.The hormonal assays were performed by using commercially available Enzyme Linked Immunosorbant Assay (ELISA) kits.
Results: No Significant difference was observed between concentration of serum testosterone, cortisol and testosterone to cortisol ratio in week one compare to week four. However, with reduction of training intensity at fifth week the concentration of testosterone significantly decreased (P
