Normal liver function is of crucial importance for metabolism and might be affected by exercise training. Accordingly, the aim of this study was to investigate the effects of 8 weeks of resistance training with various intensities on liver function test results in obese males. According to the inclusion criteria of the study, 32 obese males were selected and randomly assigned to 4 groups (each group 8 subjects): control, resistance training with low intensity (30% 1-RM), resistance training with moderate intensity (50% 1-RM) and resistance training with high intensity (70% 1-RM). Three groups carried out the resistance training with different intensities 3 times a week. Blood samples were measured in the pretest, mid-test and posttest (after 12 hours of overnight fasting). The collected data were analyzed by variance analysis test with repeated measures. Body fat percent, ALT, GGT and AST significantly reduced in experimental groups compared with the control group (P<0.05). However, no significant changes were observed in non-enzymatic markers (TB, ALB). According to these results, it can be concluded that resistance training improves enzymatic markers of liver function in obese males. Furthermore, resistance training with low intensity and higher frequency can be more beneficial.
