The Effect of High-Intensity Interval Training on Liver Enzymes in Active and Inactive Women

Background: owing to the decrease in the level of physical activity in today’s world, it seems that weight gain and fat mass are among the most important causes of non-alcoholic fatty liver disease. studies have also reported the beneficial effects of regular and long-term aerobic exercise on disease prevention. therefore, the present study aimed to investigate the effect of high-intensity interval training (hiit) on serum levels of alanine aminotransferase (alt) and aspartate aminotransferase (ast) in active and inactive women. methods: in this quasi-experimental applied study, 40 female students purposefully selected (20 active and 20 inactive) based on availability who were divided into the passive group (n = 10 in the training group and n = 10 in the control group) and the active group (n = 10 in the training group and n = 10 in the control group). then the training groups performed the selected hiit for 6 weeks and three sessions per week. the levels of research variables were measured in the serum pretest and post-test. results: the findings showed hiit decreased alt serum levels in the active training group (p = 0.03, md = 3.50) and inactive training group (p = 0.002, md = 5.30) compared to the active control group; however, there was no significant difference in terms of ast levels in the research groups (p = 0.46, f = 0.86). conclusions: it seems that hiit independently of weight changes and body mass index can decrease alt in active and inactive women.
