The effect of eight weeks of aerobic exercise and green tea supplementation on apelin and fat profile of overweight and obese women

Apelin as an adipokine is secreted from adipose tissue and affects various physiological processes, including the modulation of cardiovascular function, glucose homeostasis. The aim of this study is the effect of eight weeks of aerobic training and green tea supplementation on apelin and fat profile.

In this research, 32 overweight and obese non-athletes (age: 25-35 years old) in District 4 of Tehran were included in the study in four groups of 8 people including green tea and exercise group, green tea group, exercise group and control group. The training program was three days a week for 8 weeks and there was 48 hours of rest between sessions. The dose of green tea supplement was 3 capsules of 450 mg green tea extract per day after 3 main meals, breakfast, lunch and dinner. Then the serum level of apelin, total cholesterol, HDL, LDL, and BMI were determined before and after the study in the groups. Data analysis was done with SPSS 25 software and covariance test was used to compare the averages of the groups.

The findings of the research showed that eight weeks of aerobic training and green tea consumption had a significant difference on the effect of apelin in the studied groups compared to each other (P=0.043). Eight weeks of aerobic exercise and consumption of green tea did not have significant differences on cholesterol levels in the studied groups compared to each other (P=0.933). Eight weeks of aerobic training and consumption of green tea had a significant difference on (P=0.038) HDL and (P=0.012) LDL in the studied groups.

According to the results of the present study, it seems that aerobic exercise along with green tea consumption reduces apelin levels and improves the body composition and fat profile of overweight and obese women.
