Comparison the Effect of High Intensity Interval Training with and without Portulaca Oleracea Extract on Serum Level of MDA and TAC in Rats with Non-Alcoholic Fatty Liver Disease

Introduction and  Oxidative stress and subsequent oxidative damage is one of the main factors in the development of non-alcoholic fatty liver disease (NAFLD). The aim of present study was to investigate comparison the effect of High Intensity Interval Training (HIIT) with and without Portulaca Oleracea Extract on Serum Level of Malondialdehyde (MDA) and Total Antioxidant Capacity (TAC) in Rats with (NAFLD). Twenty five male Wistar rats were randomly divided into five groups: healthy control, fatty liver control, Portulaca Oleracea, HIIT and HIIT+ Portulaca Oleracea. To induce NAFLD, the rats were fed a high-fat diet for 12 weeks. Portulaca Oleracea supplement at 400 mg/kg was given to the experimental groups. HIIT was performed for 8 weeks, 5 sessions per week with 7 repetitions of 1 minute at 90% maximum speed accompanied by active rest intervals including 2 minutes of running at 20% mmaximum speed. To analyze the data, one-way analysis of variance and Tukey's post hoc test were used at the significance level of p<0.05. Serum Level of MDA in fatty liver control was higher than healthy control group (P=0.034). Level of this index in Portulaca Oleracea Extract and HIIT+ Portulaca Oleracea groups were significantly lower than fatty liver control group (P values 0.021 and 0.049 respectively). But No significant difference was observed in the serum level of MDA in the HIIT group compared to the fatty liver control group (P=0.08). Serum level of TAC were significantly higher in Portulaca Oleracea Extract than healthy control and fatty liver control groups (P values 0.044 and 0.001 respectively). Level of this index in HIIT+ Portulaca Oleracea Extract group was significantly higher than fatty liver control group (P=0.003).Discussion and It seems that long term HIIT and Consumption of Portulaca Oleracea extract by reducing lipid peroxidation and improving antioxidant factors in NAFLD subjects, can play an important role in controlling the progress of this disease.
