Effects of green tea consumption and aerobic- resistance training on lipid profile and body composition in overweight and obese postmenopausal women

Background: It seems that green tea and exercise training may have benefits for improving body composition and blood lipids. However, there are limited documents in the menopause population. Therefore, the aim of this study was to evaluate effects of green tea consumption and aerobic- resistance training on lipid profile and body composition in overweight and obese postmenopausal women. Materials and methods: Using a semi-experimental design, 20 menopausal volunteers women were randomly assigned to experimental (n=10, aerobic-resistance training and green tea consumption) or a control (n=10, no intervention). Intervention group received daily consumption of green tea (340 mg per day) and aerobic- resistance exercise training (three 60 min sessions per week) for 6 weeks. Subjects were tested for changes in body composition and serum lipids before and after the end of the intervention period. Data were analyzed using independent t - test, Mann-Whitney U, paired t- test and Wilcoxon by SPSS software version 16. Results: Body composition analysis revealed reduction in BMI (p=0.005) and body fat percentage (p-0.003) after 6-week intervention. However, there was no significant changes in WHR and blood lipids in the intervention group. In otherwise, there were no significant differences in all measurement, except body fat percentage (p=0.013), in between groups analysis. Conclusion: According to the study results, it is recommended that green tea combined with aerobic- resistance training are used for improving body composition in menopausal women.
