Introduction: According to confirmed beneficial effects of physical activity during pregnancy, this study was performed with aim to investigate active and passive lifestyle on insulin resistance and the levels of AST and ALT liver enzymes in pregnant women at second trimester of pregnancy.
Methods: This cross-sectional study was performed on 80 pregnant women at second trimester in Isfahan at 2015. After completing the consent form and Pregnancy Physical Activity Questionnaire (PPAQ) based on lifestyle and doing and not doing daily walking were divided to two groups of active and passive lifestyle and were compared in terms of insulin resistance and the levels of AST and ALT liver enzymes. Data was analyzed using SPSS software (version 18) and Kolmogorov-Smirnov test and t-test. PResults: Serum levels of AST liver enzymes in active pregnant women who had daily walk were significantly lower than inactive women (P=0.018), but there was no significant difference between two groups in terms of ALT levels (P=0.079) and insulin resistance (P=0.146).
Conclusion: Physical activity during pregnancy is effective on serum levels of AST liver enzymes, but according to the evaluation of control variables, ALT liver enzyme levels and insulin resistance were not significantly different due to walking with slow speed, long hours of immobility (11.8 ± 2.5)  and sleep longer than the standard (9.9 ± 2.00).
