Introduction: The assessment of changes in liver Aminotranspherases and Insulin resistance following 4 weeks of exercise trainings have been of great importance in order to prevent liver diseases. The purpose of present study is to determine the effect of 4 weeks of high intensity interval trainings together with ginger on serum levels of liver enzymes and insulin resistance in pioneer football players. Materials and Methods: In this semi-experimental study, 46 football pioneer men (40-50 years) were selected according to selective and on purpose sampling, and were divided into 4 groups of Ginger+Training, Gnger, Training+placebo and control. The training groups performed high intensity trainings for 4 weeks with 90% HRmax while supplementation groups consumed 3×1000 mg ginger capsules daily. Blood sampling was done before and 48 hours after the intervention in fasting state. Data were analyzed using Shapiro-wilk, Two way ANOVA and Tukey post hoc tests in p < 0.05 significant level. Results: 4 weeks of ginger and HIIT decreased HOMA, ALT, AST, Glucose, Insulin, weight, WC and BMI significantly in experimental groups (Ginger, Train-Ginger, Train-placebo) compared to pretest (p≤0.05). The mean changes in mentioned indices showed better improvements in ginger+training group compared to other groups (p≤0.05). Conclusion: It seems that ginger intake together with high intensity interval exercises is an efficient factor in non-alcoholic fatty liver prevention and improvement by augmentation in fat metabolism through putting desirable results on serum liver enzymes, insulin resistance and body composition in pioneer football men players.

Introduction: Research has shown that various exercises may have different effects on serum levels of brain-derived neurotrophic factor (BDNF). However, there is little information on the interactive effect of intense interval exercises through the effect on weight, body mass index, and waist to hip on BDNF. Hence, the purpose of the present study was to investigate the effect of 6 weeks of high-intensity interval training on serum levels of brain-derived neurotrophic factor and body composition of inactive male students. Materials and Methods: In this quasi-experimental study, 16 non-athlete male students from Sistan and Baluchestan University were divided into two groups of 8 as control and training through simple randomization. The training group, performed 6 weeks of high-intensity interval training, in a 20-meter shuttle run for 30 seconds with a 90 percent maximum heart rate and 30 seconds active rest between each repetition was performed. The control group did not perform activity. BDNF values were measured 24 hours before and 48 hours after the first and last training sessions of exercise using ELISA method by commercial kits. Data were analyzed using independent t-test and t-paired test at p≤0.05level. Results: In the present study, the findings showed that after 6 weeks, weight (p = 0.008) and body mass index (p = 0.005), decreased in high-intensity interval training group compared to control one, which was consistent with a significant increase in serum levels of BDNF (p = 0.031). While, none of the variables significantly changed in control group (p >0.05), in addition, there was a significant increase in serum contents of BDNFin HIIT group compared to control (p = 0.002). Conclusion: Regarding the parameters of study, it can be concluded that high-intensity interval training improve BDNF through reduction in weight and BMI in inactive male students.
