        Background: This study was conducted to evaluate the effect of eight weeks of High-Intensity Interval Training (HIIT) on adiponectin and AST, ALT, and ALP enzymes in obese and overweight boys. Materials and Methods: Subjects were 22 boys aged 12-14 years old, who were randomly assigned to experimental and control groups. Experimental group: mean weight 80.08 ± 16.08, Vo2max was 36.56 ± 2.49, and BMI was 30.27 ± 5.9 and control group: mean weight 67.91 ± 7.95, and Vo2max was 44.4 ± 2.75, 38 and BMI of 60.26 ± 6.3. The experimental group performed eight weeks of HIIT training with 80% HRR intensity at 10 turns of 60 seconds, with 60 seconds rest on exercise bikes for 3 days a week. Blood samples were taken 24 and 48 hours before and after the training, ANCOVA was used for data analysis using SPSS 21 software at a significant level (p <0.05). Results: The results showed that HIIT reduced the levels of Adiponectin and AST and ALP enzymes, but this was not significant (P≥0.05). This exercise also reduced ALT and fat percentage and increased Vo2max in subjects, with changes in all three variables significant (P≤0 / 05). Conclusion: It seems HIIT can reduce the percentage of fat and ALT enzyme in children, which can help prevent many metabolic diseases. Also, HIIT can play a role in liver health in overweight and obese children. Manuscript Document

        Background: Improving athletic performance has been one of the issues that athletes have long faced. Hundreds of sports supplements for athletes have been introduced to the market in recent years. The overall aim of the present study was to investigate the interactive effect of whey supplementation and resistance training on growth hormone and IGF1 levels in Men athletes. Materials and Methods: The method of the present study was a quasi-experimental and clinical trial. 24 male working bodybuilders (mean age 26.4 ±5.3, height 173.9 ± 7.7, weight 92.3 ± 11.6 and body mass index 28.8 ± 5.4), randomly divided into 2 complementary groups + Practice and practice were divided. Before and after 8 weeks of combined exercise program and whey supplementation (50 grams daily in the supplement group), selected body composition indicators of insulin-like hormone and plasma growth hormone and physical fitness factors including lower and upper limb muscle strength, speed, endurance Upper torso muscle, and agility were assessed. To compare the results before and after supplementation and exercise in each group, paired t-test was used, and to compare the results of the two groups with each other, an independent t-test was used using SPSS software version 20 and the significance level was P≥0.05 was considered. Results: In both groups, after eight weeks of training and consumption of whey protein, the levels of growth hormone and insulin-like growth factor 1, muscle strength, and endurance increased significantly (P <0.05), but in comparison between groups in the post-test, there was a significant difference. Not observed (P <0.05). Conclusion: Whey supplementation probably does not affect growth hormone and insulin-like growth factor-1 levels and fitness factors in Men athletes. Manuscript Document
