The present study aimed to investigate the effects of combined exercise and kefir yogurt consumption on certain indicators of metabolic syndrome in overweight adolescent girls. The statistical population consisted of non-athlete female students with overweight in the age range of 20 to 30 years from the East Tehran branch of Islamic Azad University. A total of 40 individuals were selected as the research sample. Participants were randomly assigned to four groups: combined exercise group, kefir yogurt consumption group, combined exercise and kefir yogurt group, and a control group. Subjects engaged in combined exercise sessions three times a week for eight weeks. Additionally, participants in the kefir yogurt groups consumed 750 milliliters of Pegah kefir yogurt three times a day for eight weeks. The results revealed a significant difference between the combined exercise + kefir group and the other groups, indicating superior performance in the combined exercise + kefir group compared to the others. Probably, exercise training along with kefir yogurt (probiotic) consumption can have an interaction of muscle-related genes on fat tissue. تفاصيل المقالة
