Abstract

In some obese people, the lipid profile changes, which is effective in reducing health and increasing the incidence of various diseases. The aim of this research was to compare the effect of two models of rhythmic aerobic exercise and CX-WORX on the expression of some developmental genes and body composition of obese women.
The statistical population of this research was obese women with an age range of 20 to 30 years. The current method was semi-experimental with a pre-test-post-test design. Balanced aerobic exercise for eight weeks, four sessions each week and each session lasted approximately 60-95 minutes, which was determined by the intensity of exercise in the exercise program between 50% and 80% of the maximum heart rate. The CX-WORX training program protocol was performed for 8 weeks with a frequency of three sessions per week and for 45 minutes per day. The collected data were analyzed using SPSS 22 statistical software. The statistical method of one-way analysis of variance and Tukey's post hoc test was used to investigate the difference between groups at a significance level of 0.05. The findings of the present study showed that eight weeks of rhythmic aerobic training and CX-WORX increased the expression of GH and IGF genes. 1-Folstatin, muscle mass and decreased myostatin gene expression, fat mass and body mass index in obese women. Two models of exercise are effective in reducing obesity in women by making appropriate changes in growth factors and improving body composition.
