The Assessment of Changes in Liver Aminotransferases and Insulin Resistance Following 4 Weeks of High Intensity Interval Training and Ginger Supplementation in Active Middle Aged Men

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.

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.

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).

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.
