Abstract
Obesity is one of the causative factors of non-alcoholic fatty liver disease. Therefore, therapeutic strategies such as physical activity are useful in the prevention and treatment of fatty liver disease. The aim of the present study was to investigate the effect of combined training (aerobic interval + resistance) on the degree, dimensions of liver and liver enzymes in obese or overweight women with fatty liver.
22 women with non-alcoholic fatty liver (mean age 44.14 ± 6.86 and body mass index 33.87 ± 6.74) were randomly divided into two groups of 11 individuals (training and control). Training group performed Aerobic Interval Training (AIT) (2-5 sets of 4 minutes with intensity of 70 to 75% of maximal heart rate and 2 minutes active rest) with resistance training (6 stations with Performed 8 to 12 repetitions, 2-2 circuits) for 12 weeks, 3 times a week. Body composition, sonography and blood samples were measured before and after 12 weeks of training. Data were analyzed using repeated measures ANOVA (α≥0.05).
Statistical results showed that 12 weeks of combined training significantly reduced dimension and degree of liver compared with the control group (P<0.001 and P=0.009, respectively). There was also a decrease in ALT levels in the combined training but was not statistically significant (P>0.05). There was no significant difference between groups in AST enzyme (P>0.05).
According to the results of this study, it seems that women with fatty liver may be able to use a combined training program (aerobic interval and resistance) to reduce liver fat independent of weight loss and Use this program to improve fatty liver disease as a non-adjuvant therapy.
