Background and Objective: Fat deposition in the liver to the extent of more than 5% of the liver weight in the absence of significant alcohol consumption, viral infections and any etiology of liver disease is called non-alcoholic fatty liver. The aim of this study was to investigate the effect of combined exercises with the approach of "ultimate -fit" and coffee consumption on the levels of liver enzymes in middle-aged men with non-alcoholic fatty liver.
Materials and Methods: The present study was quasi-experimental with pre-test and post-test design. 44 middle-aged men with fatty liver were purposefully selected and randomly divided into four groups: combined exercise (n=11), coffee consumption (n=11), combined exercise + coffee consumption (n=11) and control (n=11). Ultrasound and blood tests were performed to determine the amount of liver enzymes before and after the implementation of the research protocol. The practice groups performed the combined program for eight weeks in three regular sessions per week. Subjects in the coffee consumption group and combined exercise+coffee consumption received 10 grams of coffee every other day. Data were analyzed by using analysis of MANCOVA.
Results: Serum levels of liver enzymes in all three experimental groups were significantly reduced compared to the control group (p < 0.05). In the experimental group, combined exercise with coffee consumption decreased alanine aminotransferase and in other cases no significant difference was observed.
Conclusion: Combined exercise intervention with coffee consumption is effective in reducing liver enzymes. This intervention can be used for sedentary middle-aged people with fatty liver who are on the verge of aging.
